Solid pinion preload spacers (Solid Spacers) replace the traditional crush sleeve in many applications allowing you to remove the pinion nut and replace a pinion seal without losing pinion preload.
The spacers are installed with shims to achieve the correct preload setting and preload cannot be compounded by over tightening the nut or over-crushing the crush sleeve. Solid spacers also prevent pinion preload loss over time, adding to the longevity of your differential parts.
