*Some models may require mode fork shift rail to be shortened. Add the Slip Yoke Eliminator to the Wrangler's NP231 transfer case and solve a couple of problems such as changing a damaged drive shaft on the trail without losing all the lubricant, or eliminating the noise, vibration and wear that develops when the NP231 is lifted. Another benefit is the beefier rear output shaft that provides a 54% increase in torque capacity. Other kit components include: specifically designed aluminum rear output housing, bearings, seals, snap rings, bolts and instructions. **CV rear drive shaft is required.

Warranty Information

SYE KIT: One year Warranty against any Defects. No Warranty if broken by excessive torque, or abuse. Seals are a wear item and will only have a one year Warranty.

  1. Top quality SYE kit 5 Star Review

    Posted by on 16th Sep 2020

    Product is build and machined to a high quality. Only problem I had was I needed to take out the needle bearings on my input gears to fit it over to the new style Shaft and it was a bit of a pain (91’ and up)

  2. My review of advance adapters sye 4 Star Review

    Posted by on 25th Oct 2016

    So far seems good, I haven't had a chance to wheel it yet. Instalation was simplestablished; however, instructions kind of lacked. They supply a big snap ring but don't say where it goes or if it must replace the current one. I would recommend them to anyone though
