Not sure what you need?
The Nitro Gear and Axle Solid Pinion Pre Load Spacer Kit is designed to provide your Jeep Wrangler JK or compatible vehicle with increased durability of your set up by getting rid of the use of a crush sleeve. Once the preload has been set, it will not change, which allows you to swap yokes or seals without worrying of crushing the factory crush sleeve.
Kit Includes:
- One (1) solid pinion preload spacer
- Pre-load adjustment shims
- Installation instructions
