Two types available. Saddle type crossmember has a square tube cross bar that welds in between the frame rails adding rigidity to the chassis. The removable saddle is bolted to this cross tube. Tubular transmission crossmember is made from 1-3/4” diameter tubing, is 38” wide and has a 6” drop. Crossmember comes with bolt-in hardware kit. Both crossmembers fit GM or Ford transmissions.
