Unlock the full potential of your F-Body or X-Body by combining it with a T-56 6-speed (GM 4th Gen F-Body or GTO versions) or T-56 Magnum Transmission.

The crossmember is engineered to improve the overall performance of your Camaro by reducing flex and increasing the rigidity of the transmission mount.

This crossmember is designed to provide an exhaust routing path with maximized ground clearance. Worn or collapsed body bushings will further diminish the available installation space and may require increased force or leverage to be applied to the crossmember to persuade it into proper position. It is highly recommended that new body bushings be installed prior to performing your engine/trans swap. No tunnel modifications needed in OE manual transmission cars.
