The SJ series Jeep Cherokee was a full-size SUV produced from 1974 through 1983 by the Jeep division of the American Motors Corporation (AMC). It was similar to the Wagoneer that was originally designed by Brooks Stevens in 1963.
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 (1963–67), although this had the same pillar and window configuration as the four-door Wagoneer.
Based on the Wagoneer, the Cherokee was marketed as the "sporty" two-door variant of Jeep's station wagon. The term "Sport Utility" appears for the first time in the 1974 Cherokee sales brochure. A four-door was not added to the lineup until 1977. Other than the base model, the trim levels of the Cherokee included the S (Sport), Chief, Golden Eagle, Golden Hawk, Limited, Classic, Sport, Pioneer, and Laredo.
Engine choices consisted of AMC I6 or V8 powerplants. When it was equipped with the net 215 hp (160 kW; 218 PS) 401 cu in (6.6 L) AMC V8 engine, it would outrun just about any other 4x4 in its class, and, with 3.07:1 highway gearing, could reach speeds in excess of 100 miles per hour (161 km/h) (early models had 120 mph speedometers). A range of AMC engines were offered: the 110 hp (82 kW; 112 PS) 258 cu in (4.2 L) inline six-cylinder, a 175 hp (130 kW; 177 PS) 360 cu in (5.9 L) V8 with two-barrel carburetor, a 195 hp (145 kW; 198 PS) four-barrel 360, or the 401 cu in (6.6 L) V8. The durable 401 had a forged crankshaft and forged connecting rods, as well as the high nickel content block of the other AMC V8s. The 401 was discontinued at the end of 1978. After acquiring AMC in 1987, Chrysler kept the 360 cu in (5.9 L) V8 in production until 1991 for the Jeep Grand Wagoneer.
The SJ Cherokee - along with the Wagoneer and J-Truck - continues to hold the record for the largest engine ever offered in a Jeep, with the 401's displacement surpassing that of even the SRT-8 Grand Cherokee's 392 cu in (6.4 L) Hemi.
A T-18/T-18a four-speed manual gearbox was standard for all years, while through 1979 the General Motors' Turbo-Hydramatic TH400, more commonly fitted to 3/4- and 1-ton trucks rather than SUVs, was optional. For comparison, the Chevy Blazer used the TH350 automatic. After 1979, the TH400 was replaced by the Chrysler's TorqueFlite 727.
A gear-driven Dana 20 transfer case with 2.03:1 low range was standard with the manual gearbox (which had a much lower first gear of 6.3:1), while the TH400 automatics received the permanent four-wheel-drive QuadraTrac system. The chain-driven, aluminum QuadraTrac was advanced at the time. It included a vacuum-operated center differential lock. The transfer case was offset, allowing it to sit just above the frame to avoid obstacles, and the chain itself is larger than nearly any other. A test by Petersen's Complete Book of Four-Wheel Drive reported that the Cherokee was the only vehicle unable to be dynoed because the transfer case would not allow the rear wheels to spin, unlike the other full-time four-wheel-drive vehicles being tested. In the off-road test, the same held true. This transfer case was also employed successfully in Baja races, for example by Roger Mears in the Baja 1000. A 2.57:1 low range was optional on QuadraTrac.
In 1975, the Cherokee Chief package was introduced. Aside from trim changes, this model received larger fenders and wider axles, allowing larger tires to be fitted to further improve off-road ability. Four-door models were not available with "wide-track" axles.
Dana 44 model axles were used both in the front and the rear at least through 1979. Brake hardware was mostly General Motors equipment (sourced from the straight axle 1/2 ton 4 x 4 light duty truck and SUV line including the six lug rims), with disc brakes up front (optional on earlier models) and drum brakes in the rear.
All Cherokees had semi-elliptical leaf springs in the front and rear.
Around the world
Cherokees were assembled in Brisbane, Australia from 1981, although their heavy fuel consumption and high cost in comparison with Japanese four-wheel drive vehicles made them uncompetitive in that market. The Australian arm of Jeep was denied permission to assemble the upcoming compact XJ model under the Button car plan, and all Cherokee assembly was discontinued in Australia by 1986, three years after the SJ had been replaced in the U.S. by the XJ.
In Argentina, the Cherokee was manufactured by Industrias Kaiser Argentina, who renamed the SUV as Jeep Gladiator, and was sold with one type of engine: the I6 Continental of the AMC, and was equipped with 3-gear manual transmission.
In February 1974, the Jeep Cherokee was the first vehicle to earn Four Wheeler Magazine's "Achievement Award" that later became the annual "Four Wheeler of the Year" recognition.
