Rugged Ridge Heavy Duty NP231 Slip Yoke Eliminator Kit
The model NP231 transfer case is a compact, chain-driven transfer case manufactured by New Venture Gear (New Process Gear) in Syracuse, New York. Since the early 80?s, the model 231 has been used in many vehicles and is designated as follows: NP231C = GM S-10, S-15 trucks & Blazers 1983 - 1991, NP231D = Dodge midsize and fullsize trucks, NP231J = Jeep Wrangler YJ & TJ, Cherokee XJ, Commanche MJ, and Grand Cherokee ZJ from 1988-03. This transfer case was first introduced in Jeep Wranglers in 1988 after replacing a 1-year run of NP207 transfer cases.
The Kit shown here is designed for all applications of the NP231J model. All "J" models of the NP231 are not created the same. There are internal differences among different year models and this kit has been designed to be compatible with each version. Our fixed yoke kit has been installed in hundreds of V8 equipped Wranglers (small block and big block) to date without a single shaft failure. Because of this success, the new output shaft carries a lifetime replacement warranty.
With this kit you need a
Custom Driveshaft.

FREQUENTLY ASKED QUESTION:
Iím installing the slip yoke eliminator kit onto my 231 transfer case and have found that the replacement main shaft is larger than my old unit. I can not reinstall the roller bearing back onto the shaft; did I get the wrong kit?
The slip yoke eliminator kit you have purchased has several improvements made to the unit including the main shaft that make it stronger than the parts you are replacing. The kit comes with the thicker main shaft that does away with the roller needle bearings all together. These parts will not be needed as stated in the installation instructions.
