P/N: RCC10-3 1973-1987 Chevy C10 2WD Pickup Double Hump Crossmember.
This crossmember is a stock replacement 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.
As a direct replacement; most transmission applications are a direct bolt into the factory crossmember holes on the lower frame rail. However the unique design of this crossmember will accommodate many transmissions including a 4L80E with slight modifications or by drilling additional mounting holes.
