Jeep CJ7 History

The early history of Jeep CJ7

The first Jeep CJ7 was introduce in 1976 and 379,299 were built during 11 years of production. It was the upgrade of CJ5. The new CJ was much more suitable for “civilian” use than its predecessors. The now fully boxed frame was widened, so stability increased. The leaf springs were altered and moved further outward, and anti-sway bars and a steering stabilizer were added for even more improvements in drivability. Also CJ7 featured another 10 inches in the wheelbase. CJ7 lacked the noticeable curvature of the doors previously seen on the CJ5. The CJ7 offered a compromise between the CJ5 shortie and the long-arm CJ-6. It was just long enough for room and comfort but short enough to get down and dirty on the trail. It has proven a popular rig on all fronts.

The CJ7 featured an optional new automatic all-wheel drive system called Quadra-Trac, a part-time two speed transfer case and an automatic transmission was also an option. Other features included an optional molded hardtop, and steel doors.

The CJ7 was available in Renegade and an upgraded Laredo model. The Laredo model featured nicer seats, steering wheel tilt, and a chrome package that included the bumpers, front grill, and mirrors. It was the first CJ that offered both the Quadra-Trac and Hydra-Matic four-wheel drive system. The standard base motor was an inline six cylinder that was 232 cubic inches through a bore and stroke of 3.75 x 3.50 inches. This engine produced 100 bhp @ 3600 rpm. Since this really didn’t cut it for most jeep drivers, there was always the optional 258 cubic inch inline six cylinder or the 304 cubic inch V8. There were also trim and convenience packages (such as the Renegade package). Locking rear differentials and winches were available options too which most buyers wanted for off-road use.

CJ7 History. Dana Models

In 1980 was the Dana Model 20 transfer case was replaced by the Dana Model 300. The new model had a much deeper low range, 2.62:1 compared to the 2.03:1 Dana 20. The change was necessary due to Jeep no longer offering anything like the granny gear found in the T18 transmission. As for the CJ7's standard axles, Jeep offered the Dana Model 30 for the front and the AMC 20 for the rear. The Dana 44 rear axle was being offered as an upgrade on select models, and later became standard in 1986. Jeep offered no optional factory front axles.

CJ7 today

Between 1980 and 1982 a diesel-powered version had been manufacturing in the Ohio factory and for export only.

In 1987, CJ7 was gone, the AMC badges were lost and the Wrangler was born. Since 1987, there has not been a vehicle produced which could compete head to head with the Wrangler. However, the Jeep CJ7 remains a vehicle in its own class. Today, it remains one of the most sought after Jeeps for off-roading, restoration, or just weekend trips to the beach. Today the CJ7 is still used in the sport of mud racing and it is a favorite for rock crawling.
