- 1945-71 Model 18 Transfer Case
Jeep 1945-71 Model 18 Transfer Case
Make Sure It Fits Your Vehicle
The Spicer/Dana 18 was used on the first CJs and their military counterparts until 1971. It was also used on all other trucks until around 1965. From 1941-71 front & rear output shafts on lower end of case were used. 1941-68 have a dual shift lever, while 1968-71 V6 models have a single shift lever. All gears are stamped with 18-8-XX. If you own one of the original Model 18 CJ Jeeps, then you don't need us to tell you how lucky you are. You're living every Jeep enthusiast's dream! Nothing feels better than tearing up the trail in a machine with such character and history. With older Jeeps come older parts, however, and a faulty transfer case may be in your future if you aren't careful.
Keep Your Four-Wheel Drive Running Smoothly
A Dana 18 transfer case is one of the most important parts of the vehicle. If you're driving it for the off-road rampaging it was built to do, you're going to be using four-wheel drive a lot. Since the transfer case is what provides power from the transmission to the wheels during four-wheel drive, it's one of the most important parts of your vehicle. If even one part of the case goes haywire, you might be parking your Jeep for a while. Nothing's worse than a Jeep in the garage instead of on the dunes.
