The 1966-1979 Corvette pinion crush sleeve sits between the two bearings on the pinion gear, this when torqued, provides the tension or force between the two bearings required for the correct rolling torque setup on the differential. Crush sleeves are one time use only, and must be replaced when the differential front yoke is removed. Requires special tools for setup.
Note: Zip also offers complete rebuild kits including all bearings, seals and shims to properly rebuild your Corvette's rear differential.
