LS Engine Mount Swap Kit GM A/G Body 78-88

The LS Engine Mount Swap Kit GM A/G Body 78-88 is a bolt-on solution engineered for enthusiasts and professional builders performing an LS-series engine swap into early General Motors A-body and G-body platforms from 1978 through 1988. This kit addresses one of the most critical challenges in LS swap projects: properly isolating engine vibration while maintaining structural integrity of the original frame mounting points. Built by Hooker—a manufacturer with decades of experience in engine mounting solutions—this kit delivers the precision alignment and durability required for street, race, and off-road applications where engine longevity and driveline stability depend on proper isolation.

The kit features zinc-plated steel construction throughout, resisting corrosion and oxidation in engine bay environments where moisture and heat are constant threats. Steel construction ensures rigid load transfer without flex under high-torque LS power outputs, while the zinc plating provides long-term corrosion resistance without compromising fatigue strength. Each mount point is precisely engineered to match the LS block's dimensional requirements while accepting the original frame attachment points on A-body and G-body chassis—eliminating the need for extensive frame modification. The bolt-on design reduces installation time and complexity, allowing technicians to complete mounting work without welding or significant fabrication, though proper torque sequencing and alignment remain essential for optimal performance and longevity.

This kit is ideal for Chevrolet Malibu, Chevelle, Monte Carlo, and Pontiac Grand AM owners undertaking modern powerplant swaps, as well as restoration shops and performance builders seeking bolt-on compatibility without custom fabrication. The compact footprint (8.9 x 3.95 x 10.05 inches) ensures fitment within factory engine bay constraints common to these vintage platforms. Proper installation requires verification of frame geometry, correct torque application, and alignment checks before final engine installation—procedures standard to any professional LS swap project. Compatibility is confirmed for 1978–1988 GM A-body and G-body vehicles; confirm your specific model year and chassis configuration before ordering to ensure fitment with aftermarket exhaust, cooling, and accessory drive systems.
