If you’re rebuilding the rear differential on your 2005–2013 C6 Corvette, the differential bushing is a critical component that is no longer available through General Motors. GM part number 89059220 has been discontinued, leaving C6 Corvette owners and rebuild shops without a reliable OEM source. Here at Texas Drivetrain Performance, we stepped up to manufacture this bushing— making TDP the only source for this essential discontinued part.
This bushing is pressed into the driver side differential side cover and supports the CV axle as it enters the differential case. It maintains precise axle alignment and reduces side-load stress on the differential internals, ensuring smooth, consistent axle movement during operation.
After GM discontinued part number 89059220, Texas Drivetrain Performance engineered and began manufacturing this bushing in-house right here in the USA. Our replacement is made from the same high-quality, heat-resistant plastic as the original GM part — ensuring the same precise fit, function, and durability as the factory component it replaces.
