IMPORTANT APPLICATION NOTES AND EXCLUSIONS
- This kit is designed specifically for the GM 7.75-inch independent rear suspension differential.
- Verify the differential application before ordering parts for a rear-end rebuild.
- Manufacturer information contains a conflict regarding ring gear bolts: the general included-components list references ring gear bolts, while the manufacturer's Technical Notes state that this kit does not come with ring gear bolts.
- Because of that conflict, ring gear bolts are intentionally omitted from the customer-facing included-components list until the exact current kit contents are confirmed.
- Do not confuse this IRS-specific kit with Yukon kits designed for other GM 7.75-inch Borg Warner differential configurations.
INSTALLATION NOTES
- Verify the GM 7.75-inch IRS differential before beginning installation.
- Differential rebuilding requires accurate measurement and setup of bearing preload, pinion depth, backlash, and gear contact pattern.
- Follow current Yukon Gear instructions and applicable factory service procedures.
- Inspect the ring and pinion gears and differential components for wear or damage during disassembly.
- Use marking compound to verify the gear contact pattern during setup.
- Check for leaks and abnormal differential noise after installation.
- Professional installation is recommended for customers without experience rebuilding and setting up differentials.
