Trans Crossmenber Kit LS Swap GM A/G Body

The Trans Crossmember Kit LS Swap GM A/G Body from HOOKER is the engineered solution for builders relocating a modern LS powerplant into classic GM A-body and G-body platforms. This kit addresses one of the most critical structural challenges in LS conversions: properly supporting and positioning the transmission while maintaining factory-correct geometry and ride quality. Whether you're dropping an LS into a 1970s Chevelle, Cutlass, or other A/G-body classic, this crossmember kit ensures your drivetrain sits at the correct angle and height relative to the engine bay and chassis.

HOOKER engineers this crossmember to handle the unique mounting points and load paths created when adapting a longitudinally-mounted LS engine to vintage GM unibody and body-on-frame architecture. The kit is precision-manufactured to work seamlessly with popular LS swap engine mounts and transmission adapters, eliminating the guesswork of custom fabrication. Proper crossmember placement prevents driveshaft angle issues, transmission torque bind, and uneven weight distribution that can compromise handling and accelerate wear on U-joints and bearings. The robust construction supports the substantial weight and vibration loads of modern LS engines while maintaining clearance for exhaust systems, cooling lines, and fuel delivery components typical in comprehensive restomod builds.

This crossmember kit is essential for serious LS conversion builders working on A-body vehicles (Chevrolet Chevelle, Pontiac GTO, Oldsmobile Cutlass) and G-body platforms (Monte Carlo, Regal, Grand Prix). Installation pairs directly with factory transmission mounting points and integrates with standard LS swap engine bay layouts, making it compatible with popular intake manifolds, alternators, and accessory drive configurations. At 23.33 pounds, the kit arrives fully assembled and ready for installation, significantly reducing fabrication time compared to custom welded solutions. Professional installers and experienced DIY builders appreciate the precision fit, which minimizes clearance issues and ensures repeatable, bolt-on reliability across multiple builds.
