This Hooker Blackheart Transmission Crossmember is designed to allow the swap of a TremecT56 Magnum manual transmission with a fifth-generation GM LT1 or LT4 Engine into a first-generation Chevrolet Camaro that is equipped with a Detroit Speed and Engineering front subframe suspension system. The crossmember provides the proper driveline inclination angle with the DSE subframe and provides clearance for up to a 3-inch exhaust.
