Advance Adapters Slip Yoke Eliminator for all Jeep NP231 transfer cases. We consider this to be the all around best slip yoke eliminator kit for nearly any vehicle with a 231 transfer case.
If you have a Wrangler with more than 4 inches of lift and/or a raised transfer case, you may want to consider a Teraflex Extreme Short SYE. Call for more details.
If you have upgraded axles and want to run a 1350 series rear drive shaft, you may want to consider our Super Duty SYE. Call for more details.

A needed upgrade.. packed nice and seems top notch quality!
Received it. Opened it. Looks great & as advertised. Looking forward to having it installed & then ordering a cv, dc, ds. But until the conversion is complete i just can't say with 100% certainly that i can recommed it. Sorry but you'll just have to wait and see. I am however not expecting any problems with this sye or the d/s that I'll order.
The hardest part of this job was getting the transfer case down, everything else is very straight forward from breaking the case apart, removing the slip yoke shaft, and removing the gears and then switching them over. Can be done in an afternoon if you have all the right stuff. I also got the rear drive shaft with the SYE and it fit like a glove. Very happy with everything Tom woods gave me, and I’ll be ordering a new front shaft soon, as well as new yokes to make everything new.
Was able to get this done in a long afternoon. Note that circlips on the output shaft requires clip pliers with flat surfaces, not the pin-style used for clips with holes in them. Don't scrimp on these; they're well worth the investment. As always, right tool for the right job makes things go quickly. Everything else was mostly simple hand tools, though an impact wrench does make some things faster and easier. Most difficult part was just muscling the transfer case. It's quite heavy (80 lbs or so from what I understand), and unwieldy to maneuver underneath the Jeep, so having an extra body there to help is crucial, along with a sturdy floor jack. As I'm finding out with this and a recent drive shaft order, Tom Woods customer service is second to none, and Advanced Adapters manufactures a great product. In the future, if either of them have a part that I need, they'll both be on an extremely short list of vendors that I'll get it from.
Sye fit perfect and real easy to install. Look forward to doing more business!
