Trans Crossmember Kit GM 4L80

The Hooker Trans Crossmember Kit GM 4L80 is a bolt-on transmission support system specifically designed for vehicles equipped with the 4L80E four-speed automatic transmission. This kit is ideal for street rods, restorations, and high-performance swaps, providing the necessary structural reinforcement when retrofitting a modern overdrive transmission into older General Motors platforms.

Constructed from robust steel, this crossmember evenly distributes the transmission load across the vehicle frame, eliminating flex and vibration that can compromise reliability and driving comfort. The design takes into account the weight and torque characteristics of the 4L80 transmission, preventing excessive driveline movement that can lead to misalignment and failure of components.

This crossmember kit is perfect for restoration specialists, custom builders, and serious enthusiasts performing 4L80E swaps into first- and second-generation Camaros, Novas, C-10 trucks, and other classic GM vehicles. The installation process involves welding to the frame and bolting to the transmission mounts, ensuring a secure fit and maintaining factory-style compatibility.
