• Axle length is 29 7/8" long - verify length against your existing axle before installation
• This axle comes with 2 spacers to accommodate multiple axle bearing options - the thin spacer (1/2") is used with sealed RW507CR bearings; the thick spacer (.826") is used with Set 9 bearings. Install the correct spacer before pressing on the bearing

• Bolt-in design retains the factory axle retention method - no C-clip elimination kit or housing modification required

Product Description

The Yukon Gear & Axle YA G8.2BOP-L is a 1541H alloy rear axle shaft engineered as a direct-fit replacement for the GM 8.2" BOP (Buick, Oldsmobile, Pontiac) bolt-in rear axle housing found in a wide range of 1964-1972 classic muscle cars and personal luxury vehicles. At 29 7/8" long with 28 splines and a 5 x 4.75" bolt pattern, this axle replaces worn or damaged factory shafts with a stronger 1541H forged alloy unit that delivers approximately 25% more strength than OEM 1040/1050 steel axles - making it an ideal upgrade for street builds, restorations, and moderate performance applications.

A standout feature of this axle is the included dual-spacer system, which accommodates both RW507CR sealed bearings (thin 1/2" spacer) and Set 9 bearings (thick .826" spacer) - eliminating the need to track down a separate bearing spacer for your specific application. The bolt-in design retains the factory axle retention method, so no housing modification or C-clip elimination kit is required for installation.

This axle is sold individually - one shaft per purchase. Wheel studs, axle bearings, and axle seals are not included and must be sourced separately. Confirm your GM 8.2" BOP housing uses bolt-in axle retention (not C-clip) and verify the 29 7/8" length matches your application before ordering. Backed by a 10-year warranty against manufacturing defects.
