Ford 9" Solid Pinion Spacer Kit Shims Included

this solid pinion spacer kit is designed to install on the pinion and preloads the pinion bearings. This is an upgrade from the crush sleeve which is prone to failure on your Aeroflow performance differential. Eliminate the worry of altering bearing preload when changing yokes while also increasing the life of your gear set by making the assembly more stable under extreme loads. Includes four shims for setting and maintaining optimal bearing tolerance.
