, one of the two main manufacturers of the
World War II military Jeep, built the first prototypes for a commercial version – the CJ, short for "civilian Jeep".
From then on, all CJ Jeeps consistently had a separate body and frame, rigid
live axles with leaf springs both front and rear, a tapering nose design with flared fenders, and a fold-flat windshield, and could be driven without doors. Also, with few exceptions, they had part-time
four-wheel drive systems, with the choice of high and low gearing, and open bodies with removable hard or soft tops.
After remaining in production through a range of model numbers, and several corporate parents, the Jeep CJ line was officially ended in 1986. More than 1.5 million CJ Jeeps were built, having continued the same basic body style for 45 years since the Jeep first appeared.
Widely regarded as "America's workhorse", the CJs have been described as "probably the most successful utility vehicle ever made." American Motors VP Joseph Cappy said the end of "CJ production will signal an end of a very important era in Jeep history." The Jeep CJ-7 was replaced in 1987 by the similar-looking

tested the MB. By 1944, the Allies were confident the war would be won, and wartime production looked to be winding down. This allowed Willys to consider designing a Jeep for the postwar civilian market. Documentation is scarce, but in early 1944, Willys seemed to have found time to start drawing up plans, and one or two prototypes dubbed CJ(-1), for "Civilian Jeep", were running by May of that year. The first CJs had apparently been created by quick modification of the regular military MB, adding a tailgate, lower gearing, a
drawbar, and a civilian-style canvas top. The first CJ served as a quick proof-of-concept test, and when a further design evolution materialized, probably became the CJ-1 by default.
They were manufactured until the CJ-2s appeared, and they were the first Jeeps built from the ground up for civilian use.
No CJ-1s built have survived, and how many were made is unknown.
CJ-2
Although at least 40 were built, the Willys-Overland CJ-2 was not available for retail sale.

s, 5.38 gears, 2.43:1 low-range transfer cases, and driver's-side tool indentations. Rear wheelwells were redesigned so that seats could be enlarged, improved, and moved rearward, and new, more weathertight top designs were tried. A canvas half-top with roll-down doors was one of several top designs tried before production.
The CJ-2 Go-Devil L-head engine was largely the same as the wartime Jeep, but used a different carburetor and ignition system.
Later models were stamped "JEEP" and were painted in a few civilian colors that translated into the "WILLYS" stamping and the colors that appeared on the first production CJ-2A Jeeps built from 1945.
The spare tire was mounted forward of the passenger-side rear wheel on the earlier models and aft of the rear wheel on later ones. The CJ-2s were likely distributed to "agricultural stations" for evaluation purposes.
Of the 40–45 CJ-2s built, serial numbers CJ2-03, CJ2-04, CJ2-06 (X30), CJ2-09 (X33), CJ2-11, CJ2-12, CJ2-14, CJ2-16, CJ2-26, CJ2-29, CJ2-32 (X56), CJ2-37 (X61), and CJ2-38 (X62) have survived, although some in very rough condition. CJ2-06 and CJ2-09 have been restored.

The lessons learned with the CJ-2 led to the development of the first full-production CJ, the 1945-1949 Willys-Overland CJ-2A, or Universal Jeep. A trademark for "AGRIJEEP" was granted in December 1944, but was not used.
The CJ-2A looked very much like a civilianized MB with a tailgate and side-mounted spare wheel. A distinct difference between the MB and the CJ-2A lay in the grilles of the two vehicles. Where the MB had recessed headlights and nine-slot grilles, the CJ-2A had larger, slightly bulging headlights, flush-mounted in a seven-slot grille. While still powered by the reliable L-134 Go-Devil engine, the CJ-2A replaced the MB's T-84 transmission with a beefier T-90 three-speed.
Production of the CJ-2A started on 17 July 1945, sharing production time with the MB – roughly 9000 more MBs were produced through September 1945.
Many of the early CJ-2As were produced using remaining stock of the military jeep components such as engine blocks, and in a few cases, modified frames. Up to serial no. 13453, the MB-style full floating rear axle was fitted. Once they were used up, the CJ got a stronger Dana / Spicer model 41.
[ Sometimes the use of MB parts was due to strikes at suppliers, such as Autolite. Since Willys produced few parts in-house and relied heavily on suppliers, it was vulnerable to strikes. Unfortunately for Willys, strikes were common after the war, and this likely contributed to low production totals in 1945 and early 1946.
Since the CJ-2A was primarily intended for farming, ranching, and industrial applications, stock CJ-2As only came with a driver seat and driver side mirror, and a wide variety of options was available, such as: front passenger seat, rear seat, center rear-view mirror, canvas top, front power take-off (PTO), rear PTO, belt pulley drive, capstan winch, governor, rear hydraulic lift, snow plow, welder, generator,] mower, disc, front bumper weight, heavy-duty springs, dual vacuum windshield wipers (stock CJ-2As were equipped with a manual wiper on the passenger side and a vacuum wiper on the driver side), dual taillights (stock CJ-2As had a taillight on the driver side and a reflector on the passenger side), hot-climate radiator, driveshaft guards, heater, side steps, and radiator brush guard.
The CJ-2As were produced in lively color combinations that in some ways symbolized the hope and promise of postwar America. True to their intended purpose, the combinations also resembled those used by the most popular farm equipment manufacturers of the day. From 1945 to mid-1946, CJ-2As were only available in two color combinations: Pasture Green with Autumn Yellow wheels and Harvest Tan with Sunset Red wheels. Additional color combinations added in mid-1946 were: Princeton Black with Harvard Red or Sunset Red wheels, Michigan Yellow with Pasture Green, Sunset Red or Americar Black wheels, Normandy Blue with Autumn Yellow or Sunset Red wheels, and Harvard Red with Autumn Yellow or Americar Black wheels. The Pasture Green and Harvest Tan combinations were dropped later in 1946. The Harvard Red combinations were dropped in 1947 and replaced with Picket Gray with Harvard Red wheels, and Luzon Red with Universal Beige wheels. In 1948, these color combinations were also added: Emerald Green with Universal Beige wheels, Potomac Gray with Harvard Red or American Black wheels. For 1949, the Picket Gray, Michigan Yellow, and Normandy Blue combinations were dropped. Olive drab was also available for export models.
On early CJ-2As, the front seats were covered in olive-drab vinyl. Around mid-1947, Slate Gray vinyl became available for certain color combinations. Later, Barcelona Red was added to the mix.
A total of 214,760 CJ-2As were produced. Because of the use of military production parts on the earliest CJ-2As, and the many changes made during its early production, restorers and collectors refer to CJ-2As up to around serial no. 34,530 as "Very Early Civilian" and from mid-1946 to about mid-1947 as "Early Civilian". Only minor changes were made after the mid-1947 models.[

CJ-3A
The Willys-Overland CJ-3A was introduced in 1949, and was in production until 1953, when replaced by the CJ-3B. It was powered by Willys' L-134 Go-Devil four-cylinder engine, with a T-90 transmission and Dana 18 transfer case, a Dana 25

front axle and Dana 41 or 44 rear axle. It featured a one-piece windshield with a vent, and wipers at the bottom. The CJ-3A had beefed-up suspension (10 leaf) to accommodate the various agricultural implements that were being built for the vehicle. Another difference was a shorter rear wheelwell (the wheelwell from the top front edge to the rear of the body is on the 3A compared to on the 2A) and moving the driver's seat rearward. As of 1951, a Farm Jeep and a Jeep Tractor version were offered; the latter was very bare-bones, for field use only, and featured a power takeoff

The CJ-3A-derived military jeep was the Willys MC (or M38), and it began complementing the Ford and Willys World War II jeeps starting in 1949.
CJ-4
The Willys-Overland CJ-4 or "X-151" was only built as an experimental concept in 1950 or 1951. It used the new Willys Hurricane engine
The Willys F4-134 Hurricane was an inline-4 piston engine and powered the famous Jeep CJ in the CJ-3B, CJ-5, and CJ-6 models. It was also used in the Willys 473 and 475 pickups, wagons, and sedan deliveries. It replaced the Willys Go Devil engine ...

. The CJ-4 body tub was an intermediate design between the straightforward raised hood from the CJ-3B and the all new curved body style of the CJ-5. The design was rejected and the vehicle was eventually sold to a factory employee.
Evidence has surfaced, that derived prototypes called CJ-4M and CJ-4MA (XM170) have also been seriously considered, as precursors to the 1951 M38A1 and M170 military Jeeps. Although the CJ-4M prototype may not have been actually built, the stretched wheelbase ambulance prototype with registration "CJ-4MA-01" turned up in 2005.

. The Kaiser parent company removed "Overland" from the Willys Motors subcompany name. The CJ-3B introduced a higher grille and hood to clear the new Willys Hurricane engine. A four-speed manual transmission became optional in 1963, at an extra cost of $194. The turning radius was . Until 1968, about 196,000 CJ-3Bs were produced, of which 155,494 were assembled in the U.S.
The CJ-3B was turned into the M606 military jeep (mostly used for export, through 1968) by equipping it with commercially available heavy-duty options, such as larger tires and springs, and by adding black-out lighting, olive drab

. Mitsubishi continued knock-down production of vehicles derived from the CJ-3B design until August 1998, when tighter emissions and safety standards finally made the Jeep obsolete. In total, about 200,000 units were built in this 45-year period. Short, medium, and long wheelbases were available, as well as a variety of bodystyles, and gasoline and diesel engines. In Japan, it was sold at a specific retail chain called Galant Shop. The Japanese GSDF refers to them as Type 73 Light Truck.
The original J3 was a basic, doorless, and roofless version, with steering on the left, rather than the right, despite Japan having left-side traffic. The first right-hand drive versions did not appear until nearly eight years later (J3R/J11R). The original J3 and its derivatives were equipped with the F-head

"Hurricane" (called JH4 by Mitsubishi, for Japanese Hurricane 4-cylinder) inline four-cylinder, originally producing at 4,000 rpm.[Ozeki, p. 140] In 1955 a slightly longer wheelbase J10 which could seat six was added, and in 1956 the J11 appeared, a two-door "delivery wagon" with a full metal body. This was considerably longer, at versus for the J3.
Local production of the JH4 engine commenced in 1955. A locally developed diesel version ( KE31) was introduced for the JC3 in 1958, originally with at 3,500 rpm but with at 3,600 rpm a few years later. Later versions used 4DR5 and 4DR6 (J23 turbo) 2.7 liter overhead-valve diesel engines. The final military version J24A produced 135PS from an improved 4DR5 engine with front-mounted air-to-air intercooler.
By 1962, the output of the gasoline JH4 engine had crept up to . By the time of the introduction of the longer J20 in 1960, a six-seater like the J10, but with a differently configurated (more permanent) front windshield, as well as available metal doors, Mitsubishi had also added small diagonal skirts to the leading edge of the Jeep's front fenders. This remained the last change to the sheetmetal up front until the end of Mitsubishi Jeep production in 1998.
Later models include 2-L, short-wheelbase, soft-top J58 (J54 with a diesel engine), and the J38 gasoline wagon on the longest wheelbase. The last iteration of the Japanese Jeeps was the J53 with diesel turbo engine.

1972 Revamp
The 1972 model year brought significant changes to the CJ-5. American Motors began fitting their own engines, which also required changes to both body and chassis. The base Willys 4-cylinder was replaced by AMC's Torque Command straight-6 engines, giving the entry-level CJ-5 the power of the previously optional Buick V6. Standard became the , and optional the , which was standard in California. Both engines used a one-barrel Carter YF carburetor.

To accommodate the new engines, the wheelbase was stretched by , and the fenders and hood were stretched by , pushing the firewall two inches closer to the rear. A new box-frame was fitted, featuring six cross-members for more rigidity. Also, a larger fuel tank was mounted, moved from under the driver's seat to under the rear, between the frame rails.
A dealer-installed radio became available in 1973, air conditioning became available via dealership in 1975. Electronic, breakerless distributors replaced breaker-point Delco distributors for the full engine line-up, and a catalytic converter was added to models equipped with the 304 V8.
In 1975, for the 1976 model year, the tub and frame were modified from earlier versions. The frame went from a partially open channel/boxed frame with riveted crossmembers, to majoritively boxed with welded crossmembers, and from parallel rails to widening fore to aft to benefit stability. and the body tub became more rounded. The windshield frame and windshield angle were also changed, meaning that tops from 1955 to 1975 will not fit a 1976-1983 CJ-5 and vice versa. The rear axle was also changed in 1976 from a Dana 44

From 1980 to 1983, the CJ-5 came standard with a "Hurricane"-branded version of the GM Iron Duke I4 with an SR4 close-ratio, four-speed manual transmission. The AMC straight-6 engine remained available as an option, but the transmission was changed from the Tremec T-150 three-speed to a Tremec T-176 close-ratio four-speed. The Dana 30 front axle was retained, but the locking hubs were changed to a five-bolt retaining pattern versus the older six-bolt.
The demise of the AMC CJ5 model has been attributed to a December 1980 ''60 Minutes'' segment where the Insurance Institute for Highway Safety

(IIHS) staged a demonstration to illustrate that the CJ5 was apt to roll over "in routine road circumstances at relatively low speeds." Years later, it was revealed the testers only managed to achieve eight rollovers out of 435 runs through a corner. The IIHS requested the testers implement "vehicle loading" (hanging weights in the vehicle's corners inside the body, where they were not apparent to the camera) to generate worst-case conditions for stability.

:The early Tuxedo Park models were trim lines designed to make the CJ "more comfortable and appealing to the general public." However, the Tuxedo Park Mark IV was claimed as a separate model from the other CJ series (marked in 1965 as the "Universal"), with more differences than past models. The Tuxedo Park Mark IV was an attempt to crack the mass market; it was, according to Jeep, “a new idea in sports cars ... the sportiest, most FUNctional car on the automotive scene." It added to the standard CJ chrome-plated bumpers, hood latches, gas cap, mirror, and tail lamp trim. Two wheelbases, and , were available, with a variety of convertible top and seat colors, and front bucket seats upholstered in "pleated British calf-grain vinyl". Sales of this model, introduced in 1965, were low.
*1969-1970 Camper
:From 1969 Kaiser-Jeep offered a camper for the CJ-5 as a factory option, but also available separately, as it would fit any CJ-5 made since 1955. The camper mounted in the "bed" of the CJ-5, extended well beyond the back of the car, and had another axle of its own, that carried most of the weight. It also extended above the front seats of a CJ-5, which is where the main sleeper was located. When AMC bought Kaiser-Jeep in 1970, they ended the Jeep camper option. With only 336 produced, the Jeep Camper is one of the rarest commercial RV models ever.[
*1969 462
:The 1969 Universal offered a "462" performance package. It was a limited-production model that featured the V6 engine, front bucket seats and a rear bench, roll bar, heavy-duty frame and springs, a locking differential, oil-pan skid plate, rear swing-out tire carrier, full wheel covers, ammeter, and oil pressure gauges; padded visors were optional.
]
*1970 Renegade I
:The 1970 "Renegade I" models continued the features of the "462" package, along with special hood trim stripes and limited colors. Renegade I production for 1970 is estimated between 250 and 500 units equipped with all of the previous performance upgrades along with a simple black stripe on the sides of the hood, new 8-inch wide white road wheels with G70x15 tires, and offered in only two bright colors: Wild Plum and Mint Green. Note that there may have been other colors produced including a pale yellow produced in October of 1969.
*1971 Renegade II
:The 1971 "Renegade II" continued the previous year's features with bright alloy road wheels (replacing the painted steel units), the addition of a black center hood stripe, and new color selections: about 200 were painted Baja Yellow, 200 Mint Green, 50 Riverside Orange, and 150 finished in Big Bad Orange, the same paint as available on the "Big Bad" AMC AMX
The AMC AMX is a two-seat GT-style muscle car produced by American Motors Corporation from 1968 through 1970. As one of just two American-built two-seaters, the AMX was in direct competition with the one-inch (2.5 cm) longer wheelbase Che ...

. AMC design studios proposed a striping scheme for a Renegade III model for the 1972 model year, but because of their popularity, the Renegade became a regular production appearance package option.
*1972-1983 Renegade
:The 1972 "Renegade" was available from 1972 to 1983 with AMC's V8 engine, alloy wheels, and a Trac-Lok limited-slip differential.
*1973 Super Jeep
:Only produced in 1973, the Super Jeep was an appearance package created because of a shortage of aluminum wheels needed for the CJ-5 Renegade versions. Only a few hundred were built.
*1977-1983 Golden Eagle
:From 1977 to 1983, the Golden Eagle package came with a soft-top or hard-top option, power disc brakes, power steering, tachometer, 304 CID V8, air conditioning, side steps, and Golden Eagle decals.[
*1979 Silver Anniversary]
:The 1979 Silver Anniversary edition was a limited-edition version (1000 units) of the Renegade model marketed to celebrate 25 years of the CJ-5. Features included a special "Quick Silver" metallic paint, black to silver accent body striping and special Renegade decals on the hood sides, black soft top, special spare tire cover, black vinyl bucket seats, and a dashboard plaque noting the CJ's production from 1954 to 1979.

Australia
In Australia, a unique variant of the CJ5/CJ6 was produced in limited numbers. In 1965, when the CJ was given the all-new Buick V6, Jeep saw the need for something similar in Australia. So, they began to fit Australian Ford Falcon 6-cylinder engines to them at their Rocklea factory in Queensland. The Jeep was fitted with an engine, pedal box, and clutch/brake system corresponding to the equivalent Falcon at the time; a 1965 CJ5 would be fitted with 1965 Falcon engine/clutch components. Combat 6 jeeps were also fitted with Australian Borg Warner differentials, and Borg Warner-brand gearboxes. Very little documentation about these Jeeps remains, and often the only way to conclusively identify them is by owner history.
Brazil
While most foreign assemblers focused on the CJ-3B, Brazil received the CJ-5, instead. After having closed their market to imported cars in 1954, assembly of the "Willys Jeep Universal" (as it was known in Brazil) from CKD kits began in 1957. By 1958, production relied on locally sourced components, with the vehicles equipped with a 2.6 liter I6 engine (also used by Willys do Brasil for passenger cars). The Universals came with a three-speed manual transmission. The Brazilian-built vehicles are easily recognized by their squared-off rear wheel openings. In 1961, a long-wheelbase version, similar to the CJ-6, was added to the line. Called the "Willys Jeep 101", it shared the chassis of the local Rural, a redesigned Willys Jeep Station Wagon

CJ-6
Introduced in 1953 as the M170 military version, the civilian CJ-6 made its debut in 1955 as a 1956 model. It was stretched version of the CJ-5 with a longer-wheelbase (101 in, 1955-1971 / 103.5 in, 1972–1981).[ The extended chassis allowed a variety of configurations, including adding a second row of seats. The M170 military version shared many of the features of the M38A1 (Military CJ-5), but had the passenger-door opening extended back to the rear wheel well. As in the CJ-5, the V6 and V8 engine choices appeared in 1965 and 1972.

CJ-5A and CJ-6A
From 1964 to 1968, Kaiser elevated the Tuxedo Park from just a trim package to a separate model for the CJ-5A and CJ-6A. A Tuxedo Park Mark IV is signified by a different prefix from a normal CJ-5 with a VIN prefix of 8322 and a CJ6a is 8422, while a normal CJ-5 VIN prefix is 8305 from 1964 to 1971.
CJ-7
The Jeep CJ-7 featured a wheelbase 10 inches longer than that of the CJ-5, with its curved side entry cutouts partially squared up to accommodate hinged doors. The other main difference between CJ-5 and CJ-7 was to the chassis, which consisted of two parallel longitudinal main c-section rails. To help improve vehicle handling and stability, the rear section of the chassis stepped out to allow the springs and shock absorbers to be mounted closer to the outside of the body. It was introduced for the 1976 model year, with 379,299 built during 11 years of production.[
Transmission options included the standard part-time two-speed transfer case, automatic, and an optional new automatic ]all-wheel drive

. Other features included an optional molded hardtop, and steel doors. The CJ-7 was also available in Renegade and Laredo models. Distinguished by their different body decals, the Laredo model featured highback leather bucket seats, a tilting steering wheel, and a chrome package that included the bumpers, front grill cover, and side mirrors. An optional Trak-Lok rear differential was available, too.
The reports of the CJ-7 were different in each type of engine: the diesel

was mated to the 4.10 ratio axle (in both Renegade and Laredo), while the 258 cubic-inch straight six and 150 cubic-inch four-cylinder used 3.73 and AMC V8 304-powered models (produced 1976–1981, which became part of the Golden Eagle version) used the 3.55 ratio axles.
A diesel-powered version was made in the Ohio factory for export only. The engines were provided by General Motors, the owners of Isuzu Motor Cars. Production of this diesel version was between 1980 and 1982. This model had the Isuzu C240 engine, T176 transmission, and Dana 300 transfer case, although reports of some being produced with the Dana 20 exist. Typically, they had 4.1-ratio, narrow-track axles.
From 1976 to 1980, the CJ-7 came equipped with a Dana 20 transfer case, Dana 30 front axle (27- or 31-spline), and a 29-spline AMC 20 rear axle, while later years, Laredo packages added tachometer, chrome bumpers, tow hooks, and interior upgrades including leather seats and clock. In 1980, the Laredo was first fitted with an AMC 20 rear axle until mid-1986, when it was equipped with a Dana 44, and all 1980 and newer CJ-7s came with the Dana 300 transfer case.
The Canadian Army took delivery of 195 militarized versions of the CJ-7 in 1985. These were put into service as a stop-gap measure between the retirement of the M38A1 and the introduction of the Bombardier Iltis. They were codified by the Canadian Forces with the Equipment Configuration Code number 121526.
The CJ-7 continues to be used in the sport of mud racing, with either the stock body or a fiberglass replica. CJ-7 has been successfully and widely used as a favorite for rock crawling, through simple and complex modification. These last Jeeps produced were also highlighted with a factory dash plaque that read, "Last of a Great Breed - This collectors-edition CJ ends an era that began with the legendary Jeep of World War II".
During its 11 years, the CJ-7 had various common trim packages:
*1976-1986 Renegade (2.4D L6-2.5-4.2-5.0 AMC 304 V8)
*1976-1980 Golden Eagle (5.0 AMC 304 V8)
*1980 Golden Hawk (5.0 AMC 304 V8)
*1980-1986 Laredo (2.4D-4.2 I6)
Jeep also produced two special edition CJ-7 packages:
*1982-1983 Limited (2,500 units were built as a limited-production luxury model; 4.2-L I6 with T5 or automatic transmissions)
*1982 Jamboree Commemorative Edition (630 numbered units built for the 30th anniversary of the Rubicon Trail; 4.2L). with only 630 units produced (560 Topaz Gold Metallic and 70 Olympic White), the CJ-7 Jamboree is the rarest CJ-7 ever built and one of the rarest Jeeps of all time. The Jamboree is in the same production rarity class as the 1971 CJ-5 Renegade-II. It is the most heavily optioned CJ ever built; it was the Rubicon of its day. All units were uniquely numbered via a dash plaque; it is the only AMC Jeep to have been numbered.

A full-length steel hardtop CJ-8 was made for the Alaskan Postal Service, using right-hand drive and automatic transmissions. Instead of the rear tailgate, the steel hardtop used a hinged barn-door opening to the back. Only 230 were produced and sold in the U.S. It was also widely sold in Venezuela and Australia as the CJ8 Overlander, with small differences, including full-length rear windows on the Overlander. Steel hardtops used on these postal Scramblers and Overlanders were known as "World Cab" tops.[CJ10 technical manual]
