Equip Your 1973-1987 Squarebody LT Swap with MuscleRods

Engineered crossmember and heavy-duty brackets from MuscleRods ensure precise engine alignment and unwavering support for your LT conversion in any 1973-1987 GM Truck (Squarebody), with all required hardware included to eliminate part hunting and minimize vibration under load. Every mount is tailored to the 1/2 ton 2WD chassis for OEM compatibility and reliable performance as soon as the swap is complete.

MuscleRods LT Engine Swap Kit for 1973-1987 GM Squarebody Truck

When adapting a modern Gen V LT into a classic Squarebody chassis, the 1973-1987 GM Truck LT Conversion Kit addresses the toughest fitment hurdles head on. Its combination of engine mounts and a reinforced crossmember delivers precise LT engine fitment within the frame rails, minimizing strain on driveline components. By matching factory mounting points on GM half ton 2WD trucks, vibration under load is held in check and alignment issues are avoided. MuscleRods organizes all brackets and fasteners in a single package so installers can focus on the swap rather than searching for missing parts.

Precision Fitment for LT Engine Integration

The conversion kit's engine mounts are tailored specifically for 1973 to 1987 GM half ton 2WD trucks, ensuring the LT engine sits squarely between 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. Attention to this level of alignment preserves engine efficiency and maintains smooth power delivery under load.

Reinforced Crossmember and Bracket Structure

A heavy duty box section crossmember and thick gauge frame brackets combine to create a unified support structure that resists twisting under torque. Welding directly to the existing rails locks the chassis and crossmember into a rigid assembly while stainless steel hardware resists corrosion over years of service. Bracket geometry positions the engine at the optimal height for accessory drive clearance, preventing interference with steering or suspension components. The result is a stable platform that minimizes vibration and keeps the powertrain firmly in place during heavy acceleration.

Fully Organized Swap Kit for Efficient Assembly

All key parts arrive pre sorted for easy access, including engine mounts, frame brackets, crossmember and brackets, transmission mount, complete hardware set, wiring harness and comprehensive instructions. This organization eliminates the hunt for compatible fasteners or specialty brackets, saving valuable time and reducing frustration on the workbench. Detailed instructions guide installers through each step, from locating mounting holes to routing electrical connections, ensuring a smooth process even for first time builders. The outcome is a turnkey solution that brings modern LT performance to a classic chassis without the need for additional fabrication.

Count on MuscleRods for precision fit and lasting performance on your LT swap. For a more robust kit that lets you customize each component to suit your needs see our Complete LT Swap Kits - LT Kit Builder.
