1973-1987 Squarebody GM Truck LT Swap Power by MuscleRods

Achieve factory precise fitment and rock solid engine support for your LT swap in any 1973-1987 GM 1/2 ton 2WD truck with the MuscleRods conversion kit, complete with all necessary hardware for a seamless installation. Its reinforced crossmember and heavy duty frame brackets lock the engine in place to minimize vibration and ensure reliable performance under load.

Complete MuscleRods LT Engine Swap Kit for 1973-1987 Squarebody GM Trucks

The 1973-1987 GM Truck LT Conversion Kit tackles the fitment challenges of installing an LT engine into a Squarebody frame, ensuring precise alignment and solid support. Delivered by MuscleRods, it includes heavy duty frame brackets, a reinforced crossmember and all the mounting hardware needed to simplify the swap process. Whether you are a seasoned technician or tackling a swap for the first time, you benefit from a reliable powertrain setup that holds firm under load.

Precision Engine Mounting for LT Series Installations

The kit features mounts tailored to GM half ton 2WD trucks from 1973 to 1987, ensuring the LT engine sits squarely in the frame rails. This precision fit eliminates common misalignment issues, reducing strain on driveline components and lowering the risk of premature wear. By matching factory mounting points, the design also streamlines the adaptation of Gen V LT engines such as LT1 and LT4 without the need for custom modifications. This attention to alignment preserves engine efficiency and maintains smooth power delivery under load.

Structural Crossmember and Frame Brackets for Solid Support

Combining a heavy-duty box section crossmember with thick gauge frame brackets, this system delivers robust support where it matters most. The crossmember welds directly to the existing rails, creating a unified structure that resists twisting under torque. Stainless hardware ensures corrosion resistance over years of service, while the bracket geometry positions the engine at the optimal height for accessory drive clearance. The result is a stable platform that minimizes vibration and keeps the powertrain firmly in place during acceleration.

Comprehensive Engine Swap Kit Components

Every necessary part arrives organized and ready for assembly, including engine and transmission mounts, crossmember brackets, a dedicated transmission mount, and a tailored wiring harness. This eliminates the hunt for compatible fasteners and specialty brackets, saving time and reducing frustration during installation. Detailed instructions guide technicians through each step, from locating mounting holes to routing electrical connections, ensuring a smooth process even for first time installers. The result is a turnkey solution that brings modern LT performance to a classic chassis without the need for fabrication shops.
