The Jeep NP231 is one of the most popular transfer cases, but it creates an extremely short rear driveshaft. These fixed yoke kits from Advance Adapters add 3 to 4 in. to the rear driveline length on a YJ, and up to 6 in. on a TJ. This results in a better driveshaft angle, eliminated driveline vibrations, and a transfer case that's ideal for trail use.

Straightforward and doable with the right tools

This kit comes with everything you need to upgrade your NP231 T-case to a fixed yoke. The new main shaft is much beefier and uses a plastic speedo drive so you don't chew up your speedo gear. Instructions are clear. Get a good pair of lock ring pliers or you won't get far. Older style cases will require you press out the old needle bearings for the new main shaft to fit. You may run into issues with a vacuum style 4x4 indicator sensor because of the new tail house design. Kit doesn't come with new driveshaft bolts so be prepared for a trip to the hardware store. ...read more

Outstanding!

Been a few years since I have ordered from Summit. I was very happy with not only the pricing but the fact that they had my part in stock. Thanks Summit Racing!
