Developed with German National Champion and World Championship A Finalist Ronald Völker, the use of Ceramic Diff Balls with the thrust bearing's design proves to facilitate ultra smooth diff action and durability over conventional thrust bearings. You will no longer need to rebuild your thrust bearing again when rebuilding your diff, simply clean it thoroughly with motor spray and apply moderate amounts of thrust bearing grease before assembling it to the differential.

Tip: Try to apply as much Thrust Bearing Grease as possible completely covering each diff ball.
