YUKON CRUSH SLEEVE FR D30 JK

Yukon Gear & Axle's Crush Sleeve for Wrangler JK Dana 30 Axles is made to the highest standards for quality and fitment. When you are replacing or upgrading your ring and pinion gears, a collapsible pinion spacer is crucial for setting the pre-load on the pinion bearings. If you should happen to over tighten the spacer, you have to discard it and start over. Thanks to Yukon, you no longer have to purchase a kit with parts that you don't need, just replace the component that is bad.
