Jeep Wrangler YJ NP231 Transfer Cases

Make Sure It Fits Your Vehicle

Since 1988, the NP231 has been the Command Trac transfer case used in Cherokees (XJ), Comanches (MJ), and Wranglers (YJ). It has been the Command Trac transfer case in the Grand Cherokee (ZJ) since its introduction. The new Wrangler (TJ) continues to use the NP231. 1987-95 YJ and 1997-04 TJ Wrangler rear of case has circular I.D. tag. Tag has model number, assembly number, serial number and low range ratio. Some 1987 Wranglers came with NP207. Your Jeep Wrangler YJ does it all. Daily commutes, mountain climbing, rock crawling, mud churning and sand blasting—you name the challenge, your YJ tackles it with a powerful four-wheel drive system. To keep such an important system functioning at its best, however, you need a working Jeep YJ transfer case to evenly split your machine's torque and deliver it to output shafts for optimal performance. Otherwise, you might find yourself stranded or at a complete standstill, putting a significant kink in your off-roading fun.

    The NP231 transfer case in your Jeep Wrangler is durable and easily serviceable, which is why despite upgrading so much of your 90s model, you've kept the original transfer case. The YJ transfer case is lightweight coming in around 70lbs but provides the strength to work with newer transmissions and engines whether automatic or manual. 4 Wheel Parts has the parts you need to service your '93 Jeep Wrangler Transfer Case or other ‘80s or ‘90s version.

    Identifying the NP231 Transfer Case
    Not sure if your 1994 Jeep Wrangler transfer case has been upgraded to a newer model, look to the case's rear for a silver and red tag. The Jeep versions have a front face for six-bolts. The 231 is also made for Dodge and Chevy. With longer adapters and only five bolts, the GM transfer case won't work in your Jeep or Dodge. If you want to make one work in your Wrangler, you'll have to purchase parts on a mix and match basis to make it compatible. You can customize your NP231 for additional torque by adding bigger planetaries, more durable tailhousing assemblies and/or chains that are wider. Don't look just at the shift mechanism because 231's come in an assortment even if they are still cumbersome. However, you can replace the “Z-gate” shifter with a universal one for an easier transmission upgrade.
