This cross member is built based on the Energy Suspension 3.1108 mount. It will fit a number of GM transmissions by sliding the cross member forwards or back in your frame and drilling four(4) 3/8" holes for mounting. Shims are included for between the cross member and trans mount to correct for drive line angle issues should there be any. Templates are included to assist in drilling mounting holes. Dual exhaust cutouts leave lots of room for exhaust coming off long tube headers or other options. Paired with the LSx swap engine mounts and this cross member, a 6L80/90e 6 speed automatic will clear the bottom of the cab in a 73-87 squarebody application with lots of room.
The cross member is extremely light and very strong. They come powder coated so they stand up to the elements and time and are very durable. The cross member is plasma CNC cut, fitted, mig welded and powder coated all in house.
