Jeep CJ-7

[Jimmyb]

The Jeep 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. The other main difference to the CJ-5 was to the chassis which hitherto 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 road springs and dampers to be mounted closer to the outside of the body. 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.

The reports of the CJ7 were different in each type of engine: the 2.4D mounted the 4.10 (the production was that both RENEGADE LAREDO), the 4.2 and 2.5 l6 rode a ratio of 3.73 while the construction with AMC V8 304 (production 76-81, which became part of the Golden Eagle version) was equipped with a ratio of 3.55. From 76 to 80 was mounted a reducer DANA 20, DANA 30 front axle (27 or 31 spline) and an AMC 20 rear very strong (a 29 spline), while in recent years production of 8cioè years' construction Laredo, where were added to the package of chrome bumpers, hooks and interior, comfortable leather seats, clock and tachometer) was fitted with a rear Dana 44 was introduced in 1980 and a gearbox 300 DANA better than the last and still in production and highly sought after by lovers of off-road.

The machine during his 11 years had various equipment packages:
Renegade 1976-1982 (2.4D L6-2.5-4.2-5.0 V
Golden Eagle 1976-1979 (5.0 V
Laredo 1982-1986 (2.4D-4.2 l6)
Jamboree Edition (Limited Edition 2500 models which were built for the 30th anniversary 2.5 and 4.2)

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. This model had the Isuzu C240 engine, T176 Transmission, Dana 300 Transfer box although there are reports of some being produced with the dana 20. Typically they had 4.1 ratio, narrow track axles.
The CJ-7 continues to be used in the sport of mud racing, with either the stock body or a fiberglass replica. It is also a favorite for rock crawling.
