The CJ-5 was influenced by new corporate owner, Kaiser, and the Korean War M38A1 Jeep. It was intended to replace the CJ-3B, but
that model continued in production. The CJ-5 repeated this pattern, continuing in production for 3 decades while three newer models
appeared. A total of 603,303 CJ-5s were produced between 1954 and 1983. In 1965, Kaiser bought the casting rights to the Buick 225
in3 (3.7 L) V6 Dauntless and the CJ-5 and CJ-6 got a new engine with 155 hp (116 kW) supplementing the Willys Hurricane engine.
The company was sold to American Motors in 1970, and the GM engine was retired after the 1971 model year. (GM's Buick division
repurchased the engine tooling in the early 1970s which served as the powerplant in several GM vehicles.) AMC began using their
inline six-cylinder engines, the 258 in3 (4.2 L) in 1972 and offering one V8 engine in the same tune as a base V8 muscle car, 304 CID.
To accommodate the new I6 the fenders and hood were stretched 3 inches (76 mm) starting in 1972. Other minor drive train changes
took place then as well. In 1976 the tub and frame were modified slightly from earlier versions. The windshield frame also changed
meaning that tops from 1955-1975 will not fit a 1976-1983 CJ-5 and vice-versa. In the early 1980s, the CJ used a "Hurricane"-branded
version of the GM Iron Duke I4.
The CJ-7 featured a longer wheel base than the CJ-5 and lacked the noticeable curvature of the doors previously seen on the CJ-5. It
was introduced in 1976 and 379,299 were built during 11 years of production. The CJ-7 featured an optional new automatic all-wheel
drive system called Quadra-Trac, as well as a part-time two speed transfer case; an automatic transmission was also an option. Other
features included an optional molded hardtop, and steel doors. The CJ-7 was also available in Renegade and an upgraded Laredo
model. Noticeable by their different body decals, the Laredo model featured nicer seats, steering wheel tilt, and a chrome package
that included the bumpers, front grill, and mirrors. An optional Trak-Lok differential was available for the rear. Ring and Pinion was
typically 3.54, but later went down to 2.73. 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 is believed to have been only between
1980 and 1982.
