Sonnax Transfer Case Split Ring Retainer $21.58
Transfer Case Split Ring Retainer
  • Fits 230 & 240 series with 1.375" Shaft Diameter
  • High-Strength Chromoly Steel that is Through-Hardened
  • Split Retainer, Retainer Ring & Snap Ring Included

  • Sonnax offers split ring retainers as an upgrade to the OE open-end style retainer that commonly breaks.

    The OE snap ring directly behind the rear output shaft bearing fails from fatigue cracks caused by the on/off loading of the snap ring. The open-end-style snap rings cannot withstand the loads from the forward force of the driveshaft.


    The driveshaft spline is designed to slide on the output shaft spline, but spline lock causes the drive shaft to directly load the OE snap ring. When the rear suspension moves up and down, the drive shaft pounds this snap ring until it breaks.

    100420-02K is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Great design on this snap ring upgrade. Best tailshaft snap ring replacement on the market. Well worth the money. Easiest repair I have ever made on a vehicle. Very happy.
