MuscleRods LS Engine Swap Kit for 1963-1972 GM C/K-10 C/K-15 Blazer K5 Jimmy

If you are tackling an LS conversion in a 1963-1972 GM pickup or K5 Blazer this kit provides precision engineered motor mounts and a crossmember that secures engine and transmission at the correct angle to prevent driveline vibration. It accommodates T56, 4L60E, 4L80E and 6L80E transmissions without requiring floor tunnel modifications to preserve the original frame structure. Compatibility with high clearance and LH8 oil pan styles helps retain factory ground clearance while reducing u-joint stress on uneven terrain. MuscleRods designed all brackets, mounts and hardware in the USA to deliver a straightforward installation and drivetrain alignment solution for both home mechanics and professional builders.

Precision Drivetrain Alignment for Vibration Reduction

The conversion kit's precision machined motor mounts and frame brackets lock the LS engine and transmission into the ideal attitude, eliminating torsional stress on U-joints and curbing chassis vibration. By preserving exact geometry between rotating components, the system delivers smoother torque transfer under load and prevents premature wear on driveline parts. Road and off-road users alike benefit from quieter operation, as proper alignment minimizes rattles and driveline noise. This attention to detail ensures the full power of a Gen III/IV LS is delivered cleanly to the rear wheels.

Flawless Transmission Integration Preserving Frame Structure

No tunnel cutting or major frame alteration is needed when fitting T56, 4L60E, 4L80E or 6L80E transmissions. The engineered crossmember and side brackets position each gearbox within the stock tunnel profile, maintaining the truck's structural integrity and classic underbody appearance. Installers save hours of fabrication work and avoid weakening the chassis by relying on the kit's precisely located mounting points. Whether you're a home mechanic or a professional builder, this approach streamlines the swap and preserves your vehicle's original frame strength.

Oil Pan Options to Optimize Ground Clearance

This kit supports both high clearance and LH8 style oil pans, giving builders the flexibility to tailor sump height to their driving needs. High clearance pans raise the sump well above uneven terrain and obstacles, ideal for lifted trucks tackling off-road trails. When standard clearance is acceptable, the LH8 pan keeps the sump close to factory frame rails, maintaining a low profile. These options eliminate the need for custom fabrication and let users balance clearance and sump capacity with simple bolt-on compatibility.

Robust American Made Bracketry for Lasting Durability

Every steel bracket and mount in this assembly is designed and manufactured in the USA to meet demanding use cases. Heavy-gauge steel components resist flex under heavy acceleration or towing loads, while the included polyurethane transmission mount cushions gear-shift shock and isolates vibration. The complete bolt kit ensures each part is secured with correct fasteners, preventing loosening over time. Backed by rigorous quality control, this kit provides installers with a dependable foundation for a long-serving LS swap.
