The CJ-5 was produced from 1955 through 1983.

Drive Train


Many engine options have been offered for the CJ-5 over it's long production run. The original engine offered in the CJ-5 was the "Hurricane" F-Head 134 I4. The first optional engine offerred for the CJ-5 was the Perkins 192 I4 diesel followed by the "Dauntless" Buick 225 V6. When AMC purchased Jeep from Kaiser, they soon made the AMC 232, 258, and 304 available in the CJ-5. The last three years of production, the GM 151 I4 was the standard engine.


The T-90 3 speed was the standard transmission for the CJ-5 for many years. It's close brother, the T-86 3 speed was used with CJ-5s with the Dauntless V6. The T-14 replaced the T-90 and later the beefy T-15 was used with CJ-5 with the 304. The T-98 was an optional 4 speed for the CJ-5 until 1971 when the T-18 became the optional 4 speed. In 1976, the T-150 became the 3 speed for the CJ-5. In 1980, the heavy duty 3 speeds and 4 speeds were no longer offered. The lighter duty SR-4, T-4, T-176, and T-5 were used. The CJ-5 never came with an automatic from the factory.

Transfer Case

The CJ-5 used the Dana 18 from '55 until '71. In '72 they switched to the Dana 20. From '80-'83 they used the Dana 300.

Front Axle

The CJ-5 was first offered with the Dana 25 until 1965. The Dana 27 replaced it and was used until 1971. From 1972-1983, the Dana 30 was used in the CJ-5.

Rear Axle

The Dana 44 with two piece shafts was used in the CJ-5 until mid-1970. A Dana 44 with one piece shafts replaced it after that until 1975. After 1976 the AMC 20 was used.

I have removed the passenger tool box from the floor pan of my 74 cj5, now a preformed carpet kit will not fit properly. What year cj5 carpet kit (without tool box) will best fit my 74 now? Thanks for any info.

i just bought a 1975 cj5 jeep. Previous owner had bought an after market valve cover. when i drove the jeep oil would spew out of the breather tube. so i bought an OEM valve cover and gasket installed it back on the jeep. I also put an oil filler cap,new pcv and plugged the crank case vent because i couldnt locate a new or one similar one. drove the jeep around the block now oil is spewing out underneath the valve cover towards the back of the engine so would that mean i have a high pressure problem in the engine?

We have just welcomed to our home a 1967 CJ5. It is all original with only one owner. I have great plans for this gem but have some questions concerning the steering on this model. We would like to put a 2" lift kit in it. Is the standard steering able to accommodate the kit?
