Torque Tube Bushings for Non-Z06 shifter boxes are available in Polyurethane or machined from Delrin. We recommend Poly for use on street cars. Delrin offers a firmer feel but does not dampen quite as well as Poly bushings. The factory steel insert is NOT included with Poly Bushings. If you need factory inserts or answers to any other questions please let us know via email CLICK HERE
Our Billet Solid Bushings fit in non-Z06 boxes, feel and function exactly the same as a Z06 box. Solid bushings press together and can be installed by clamping in a vise or tapping with a hammer. They form a tight fit and can be very difficult to remove, for this reason we do not recommend removing them.
