Here we have our custom built transmission replacement crossmembers for the E4od and the obs zf5 transmission. All cnc cut from 1/4” steel and mig welder for superior strength and durability. These crossmembers are a direct bolt in in place of the factory Crossmember, and you don’t have to worry about if you have done a super duty axle swap if those brackets set in place of where the Crossmember sits it doesn’t effect the installation of these crossmembers.
