Jeep Gladiator (JT)
The Jeep Gladiator is a midsize pickup truck manufactured by the Jeep division of Stellantis North America (formerly FCA US). It was introduced at the 2018 Los Angeles Auto Show on November 28, 2018, and went on sale in the spring of 2019. Based on the same platform as the Wrangler JL, the Gladiator is Jeep's first pickup truck since the Comanche was discontinued in 1992. Jeep Gladiator is also being marketed in Australia, as the first market outside Americas. History The vehicle's name harkens back to the original Jeep Gladiator, made from 1962 through 1988 and known as the J-Series after 1971. Jeep considered reviving the Gladiator name alongside Comanche and most commonly Scrambler, as well as simply using a new name, before deciding on Gladiator, feeling it fits the truck the best. A two-door version of a Jeep Scrambler pickup based on a lengthened Wrangler was shown in 2003 at the National Automobile Dealers Association meeting. In late-2004 the Jeep Gladiator conce ...

Jeep
Jeep is an American automobile marque, now owned by multi-national corporation Stellantis. Jeep has been part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with remaining assets, from its previous owner American Motors Corporation (AMC). Jeep's current product range consists solely of sport utility vehicles – both crossovers and fully off-road worthy SUVs and models, including one pickup truck. Previously, Jeep's range included other pick-ups, as well as small vans, and a few roadsters. Some of Jeep's vehicles—such as the Grand Cherokee—reach into the luxury SUV segment, a market segment the 1963 Wagoneer is considered to have started. Jeep sold 1.4 million SUVs globally in 2016, up from 500,000 in 2008, two-thirds of which in North America, and was Fiat-Chrysler's best selling brand in the U.S. during the first half of 2017. In the U.S. alone, over 2400 dealerships hold franchise rights to sell Jeep-branded vehicles, and if Jeep were spun off ...

Jeep Liberty (KJ)
The Jeep Liberty (KJ), or Jeep Cherokee (KJ) outside North America, is a compact SUV that was produced by Jeep from 2002 to 2007. Introduced in May 2001 as a replacement for the Cherokee (XJ), the unibody Liberty was priced between the Wrangler and Grand Cherokee. It was the smallest of the 4-door Jeep SUVs up until the car platform based 4-door Compass and Patriot arrived for 2007. Description Inspired by styling from the ''Dakar'' and ''Jeepster'' concept vehicles, the Liberty was designed by Bob Boniface in 1998. Intended as a replacement for the discontinued Jeep Cherokee (XJ), the Liberty was the first Jeep vehicle to use rack and pinion steering and the two then-new '' PowerTech'' engines: the 2.4 L straight-4, which was discontinued in 2006, and the 3.7 L V6. However, the Liberty was not the first Jeep vehicle to use an independent front suspension, as the Jeep Wagoneer first used it in the 1963 model. But, that independent front suspension was limited to four wheel ...

Limited-slip Differential
A limited-slip differential (LSD) is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. Early history In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance. The ZF "sliding pins and cams" became available, and one example was the Type B-70 used during the Second World War in the military VWs ( Kübelwagen and Schwimmwa ...

Jeep CJ
The Jeep CJ models are a series and a range of small, open-bodied off-road vehicles and compact pickup trucks, built and sold by several successive incarnations of the Jeep automobile marque from 1945 to 1986. The 1945 Willys Jeep was the world's first mass-produced civilian four-wheel drive car. In 1944, Willys-Overland, 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 li ...

Jeep Cherokee (SJ)
: ''See also Jeep Cherokee for other models using this name.'' The SJ series Jeep Cherokee is a full-size SUV that was produced from 1974 through 1983 by Jeep. It was based on the Wagoneer that was originally designed by Brooks Stevens in 1963. Development The Cherokee was a redesigned reintroduction of a two-door body style, with a single fixed rear side window with an optional flip-out section. Previously, a two-door version had been available in the Jeep Wagoneer line from 1963 to 1967, although this had the same pillar and window configuration as the four-door Wagoneer. The Cherokee was marketed as the "sporty" two-door variant of Jeep's station wagon. The term "Sport Utility Vehicle" appears for the first time in the 1974 Cherokee sales brochure. A four-door was not added to the lineup until 1977. The initial, 1974 Cherokees were only available in the standard "narrow track" configuration as base models (Model 16), or top-of-the-line S models (Model 17). Later, the ...

Dodge
Dodge is an American brand of automobiles and a division of Stellantis, based in Auburn Hills, Michigan. Dodge vehicles have historically included performance cars, and for much of its existence Dodge was Chrysler's mid-priced brand above Plymouth. Founded as the Dodge Brothers Company machine shop by brothers Horace Elgin Dodge and John Francis Dodge in the early 1900s, Dodge was originally a supplier of parts and assemblies to Detroit-based automakers like Ford. They began building complete automobiles under the "Dodge Brothers" brand in 1914, predating the founding of Chrysler Corporation. The factory located in Hamtramck, Michigan was the Dodge main factory from 1910 until it closed in January 1980. John Dodge died from the Spanish flu in January 1920, having lungs weakened by tuberculosis 20 years earlier.
