Fitment & Important Notes
Interchanges with GM part number 12456211
- 1997–1999 C5 Corvette (automatic only) This bushing must be removed and replaced any time the torque tube bearings are replaced. The bushing is pressed in and covers a bolt that retains the rear torque tube transmission shaft — the bolt cannot be accessed until the bushing is removed. Because of the way it is pressed in, removal requires cutting into the side and using a chisel and hammer to knock it loose. This process destroys the bushing, making replacement mandatory.
- 2000 C5 Corvette (automatic only) This was a split production year. Some 2000 automatic Corvettes require bushing removal for a bearing replacement and some do not. We recommend disassembling the torque tube before ordering to confirm exactly what your specific unit requires.
- 2001–2013 C5/C6 Corvette (automatic/manual) This bushing is present but does not need to be removed in order to perform a bearing replacement. Replacement is only necessary if the bushing itself is worn or damaged.
- 2014–2019 C7 Corvette (automatic/manual) This bushing is used in the rear and/or front of the C7 torque tube. The C7 arrangement differs from the C5/C6 — if the coupler bushings become damaged on a C7, they will cause these insulator bushings to fail as well, meaning replacement is needed more frequently than on C5/C6 models.
