Slip Yoke Eliminator for all Jeep NP231 transfer cases. Choose between Advance Adapters or Teraflex brands, both kits are essentially the same design. We consider these to be the all around best slip yoke eliminator kit for nearly any vehicle with a 231 transfer case. This is an especially common slip yoke eliminator for TJ and YJ Wranglers. 

If you have a TJ Wrangler or a YJ Wrangler with more than 4 inches of lift and/or a raised transfer case, you may want to consider a Teraflex Extreme Short SYE. 

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.

Products/customers service

Got my products on time and build quality was great but I have to say the customer service was outstanding I had a mishap on one my parts and they took care of me right away.

Solid kit. Works.

Ray Mayhew
Great product, fitment was excellent with very detailed and comprehensive instructions.

I bought the NP231 SYE kit, along with a double cardan custom driveline and adjustable upper control arms for my lifted 2003 Jeep Wrangle TJ. The products shipped very quickly. Everything you needed for the install was included. This combination of parts was exactly what I needed to cure the drivetrain vibration in my lifted jeep.
The staff at Tom Woods were very helpful at time of purchase to assist me to get what I needed. I would definitely recommend them to anyone with a lifted jeep that is having drivetrain vibration.

Great SYE for the price

Everything in my AA sye seemed good quality and very good price. I received it in less than a week! A little disappointed in driveshaft availability but that’s not Tom Woods fault...
