A new Advanced Adapters crossmember for the NV3550 transmission must also be used. Since this 5 speed does not offer angular support pads and our adapter is two short to have these provisions, Advanced Adapters designed a new crossmember support for the new transmission. Advanced Adapters new crossmember bolts to the stock crossmember frame hole and includes a new rubber support. The crossmember is designed to fit both stock exhaust and header applications. NOTE: The crossmember will require some additional modifications when using and Atlas transfer case. Will bolt in orginal holes on frame when used with original Dana 20 transfer case.
