Trans Crossmember Swap Kit GM LS Auto Trans

The HOOKER Trans Crossmember Swap Kit for GM LS Auto Transmission is a bolt-on engine swap solution engineered for modern powertrain conversions in classic GM F-Body and X-Body platforms. This crossmember kit enables the direct installation of LS-series engines paired with 4L60E, 4L65E, 4L70E, or 4L75E transmissions, eliminating the custom fabrication typically required when retrofitting newer engine and transmission combinations into older chassis.

Manufactured from steel and finished with black powder coat for corrosion resistance, this kit provides the structural support needed to properly locate and secure the transmission assembly while maintaining correct driveline geometry. The bolt-on design means no welding is required—critical for builders who want to preserve originality or avoid permanent frame modifications. The compact footprint (11 x 5.5 x 32 inches, weighing 17.15 lbs) integrates efficiently within the original vehicle's transmission tunnel while accommodating the additional height and width of modern automatic transmissions.

This kit is essential for restomod builders and performance enthusiasts upgrading second-generation F-Bodies (Camaro/Firebird) and X-Bodies (Citation/Omega) with LS power. Rather than spending countless hours measuring, fabricating, and test-fitting a custom crossmember, this purpose-built solution accelerates the build timeline while ensuring proper transmission support, alignment, and clearance. The HOOKER name carries decades of experience in engine swap applications, making this a dependable foundation for reliable long-term operation.
