Spohn 1993-2002 Camaro & Firebird Torque Arm Front Crossmember-longtube version This torque arm front crossmember is for vehicles running long tube headers/y-pipe set ups. If you have a Spohn standard exhaust version torque arm and want to convert to the long tube style set-up then this is the crossmember you need. Everything else in our torque arm kit is the same, you can just swap out crossmembers.
