If you’re rebuilding the torque tube on your 2001–2013 C5 or C6 Corvette, there’s a good chance you’ve already discovered that the front insulator bushing is no longer available from General Motors. Both original part numbers — 12456214 and 88893996 — have been discontinued, leaving Corvette owners and rebuild shops without a reliable OEM source. Here at Texas Drivetrain Performance, we CNC-machine this bushing in-house as a precise, direct factory replacement — so your torque tube rebuild doesn’t have to stop because of a discontinued part.
