Advance Adapters Sye Kit

    
 
This Heavy Duty Slip Yoke eliminator kit fits Jeep NP231 transfer cases. This kit features a new 1 3/8”-32 spline rear output shaft, 356-T6 heat treated aluminum alloy tailhousing, 1310 c.v. yoke (other styles of yokes available), bearings, fastening hardware, and detailed instructions.
 

Note: We have designed our heavy duty fixed yoke output shaft with the most current design shaft found in the New Process Gear NP231. This current design shaft was introduced in 1997. Jeep vehicles using the early NP231 can still use our kit, providing that the needle bearings are removed from the stock drive sprockets.
