What is the purpose of differential pinion shims?

Differential pinion shims are used to adjust the pinion angle and the distance between the pinion gear and the ring gear. This adjustment is critical for setting the correct preload and backlash, which ensures the gears mesh properly for quiet and efficient operation.

What vehicles does this Omix shim kit fit?

This kit is specifically designed for 2007-2018 Jeep Wrangler JK and JKU Rubicon models that have the Dana 44 front or rear locking differentials. It replaces the original equipment part number 68003556AA.

Does this kit include everything needed to set differential backlash?

This kit provides the necessary shims for adjusting pinion angle, preload, and backlash. However, it does not include other components like bearings, seals, or gear sets, which may be required for a complete differential rebuild. Always refer to your service manual for a full list of parts needed for your specific repair.
