Complete MuscleRods LS Engine Swap Kit for 1968-1972 A-Body Chevelle/El Camino/GTO/Tempest/Cutlass/442/Skylark

Outfitting a 1968-1972 GM A-Body car with a modern LS engine often runs into clearance and alignment hurdles, and the 1968-1972 A-Body LS Conversion Kit tackles these challenges squarely. It includes precisely engineered engine and transmission mounts plus a crossmember that holds drivetrain angles within factory specification. This kit accommodates both 4L60E and 4L80E transmissions without altering the tunnel, preserving the original structure of your Chevelle, El Camino, GTO, Cutlass or Skylark. Whether you are a seasoned mechanic or a dedicated hobbyist, this solution streamlines the swap process while maintaining reliability.

Precision Engine and Transmission Alignment

This conversion kit employs custom motor mounts and a purpose-built transmission crossmember to maintain the factory drivetrain angle on 1968 to 1972 GM A Body cars. TIG-style welds on heavy-gauge brackets ensure consistent tolerances that resist engine torque and prevent driveline vibrations. By preserving the original alignment, the kit delivers smoother operation, quieter performance, and extends the life of u-joints and driveshaft components.

Seamless Transmission Compatibility

Designed for direct fitment with both 4L60E and 4L80E transmissions, the crossmember and transmission brackets align precisely with the factory tunnel-no cutting or reshaping required. Ample clearance is built in to accommodate a high clearance oil pan and a variety of popular LS engine intake manifolds. The included polyurethane transmission mount and spacer kit lock everything securely in place and isolate noise and vibration from the chassis.

Streamlined Installation Process

This all-inclusive kit arrives ready for assembly with two motor mounts, two frame brackets, a transmission crossmember, outer brackets, a polyurethane mount, spacers, and a complete hardware pack. Each piece is laser-cut or CNC-formed to exact dimensions, allowing builders to bolt in their LS engine quickly without complex mockups. Whether you are a hobbyist or a professional, the precise fitment reduces trial-and-error, saving hours of labor and frustration.

USA Craftsmanship for Reliable Performance

All components are proudly made in the USA from high-strength steel and finished with a durable powder coat for superior corrosion resistance. Welds are performed by certified technicians to guarantee structural integrity under repeated torque cycles. The combination of robust materials and precision fabrication ensures your LS swap kit stands up to demanding road and weather conditions for years of dependable service.
