NP231 SYE

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.

Nice Fit, Easy to Install

Ordered and installed, then measured and ordered a driveshaft for the Jeep Grand Cherokee ZJ. No problems during the installation of either.

SYE Review

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.

XJ SYE

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.
