Yukon Gear GM 9.5in Ring Gear Bolt

OEM-Spec Ring Gear Bolt for GM 9.5-Inch Rear Differential

The Yukon Gear YUKYSPBLT-017 is a precision ring gear bolt manufactured as a direct OEM-replacement fastener for the GM 9.5-inch rear differential. The GM 9.5in axle is a heavy-duty rear end found in full-size Silverado, Sierra, Suburban, Tahoe, and Yukon platforms, where ring gear bolts must withstand substantial torque loads from high-capacity towing and hauling. This bolt is machined to OEM thread pitch, grip length, and head bearing surface specifications to deliver factory-equivalent clamping force when torqued to spec. It pairs directly with Yukon's GM 9.5in ring and pinion sets for a complete rebuild solution.

Frequently Asked Questions

What vehicles use the GM 9.5in rear differential?
The GM 9.5in rear axle is found in full-size Chevrolet Silverado, GMC Sierra, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon trucks and SUVs, primarily in GMT800 and GMT900 platform applications from 1988 onward.

How many ring gear bolts does the GM 9.5in differential use?
The GM 9.5in ring gear uses twelve bolts. Order twelve for a complete replacement set.

Why replace ring gear bolts when doing a ring and pinion swap?
Ring gear bolts are torqued-to-yield fasteners in many applications. Reusing stretched bolts delivers inconsistent clamping force, which can allow the ring gear to shift on the carrier, causing gear failure. Always install new bolts with a new ring gear.

What torque should GM 9.5in ring gear bolts be tightened to?
Factory specification is approximately 89 ft-lb for this application. Always verify using the factory service manual for your specific model year, as torque values can vary across production years.

Does this bolt require thread-lock compound?
GM does not specify thread-lock for this application. A clean, properly torqued bolt with good thread engagement provides the required clamping force without additional sealant. Follow the factory service manual.

Is this the same bolt used on GM 9.25in or 8.5in differentials?
No. Each GM differential axle uses a specific ring gear bolt specification. Verify your axle ring gear diameter before ordering to ensure the correct bolt is selected.

What gear oil should I use after reassembly?
The GM 9.5in differential uses 75W-90 GL-5 gear oil. If the carrier has a limited-slip unit, add the specified GM limited-slip friction modifier additive.

What is the warranty on this bolt?
Yukon covers the YUKYSPBLT-017 with a Lifetime Limited Warranty. Drivetrain components qualify for consumer protections under the Magnuson-Moss Warranty Act.

Installation Notes

• Clean all bolt holes in the ring gear and carrier thoroughly before installation
• Replace all twelve ring gear bolts as a complete set; never mix old and new hardware
• Torque bolts in a crossing pattern to the factory specification of approximately 89 ft-lb
• Use a calibrated torque wrench for final torque; do not use an impact wrench for the final pass
• Verify ring gear runout with a dial indicator after torquing to confirm proper seating
