As a direct replacement most transmission applications are a direct bolt into the factory crossmember holes on the lower frame rail.

This crossmember is a stock replacement and LS swap crossmember designed to allow a dual exhaust system to be routed under the crossmember, allowing ease of header connection, while keeping the exhaust above the frame rails. 

Great for stock chassis and lowered trucks alike.

The unique design of this crossmember accommodates large heavy duty transmissions such as a 4L80E with slight modifications, or by repositioning and drilling additional mounting holes.
