The HOOKER Engine Mount Swap Kit for GM A-Body with LS Engine (MPN 71221008HKR) is a bolt-on motor mount solution engineered for LS-series engine conversions into classic 1964–1967 GM A-Body platforms. This steel, zinc-plated pair delivers the structural support and alignment precision required when retrofitting modern LS powerplants into vintage muscle car and street rod builds where original mounting geometry no longer applies.
Constructed from welded steel with zinc plating for corrosion resistance, the mounting surfaces are machined to factory tolerances to ensure proper engine positioning and minimal vibration transmission to the chassis. Bolt-on installation eliminates the need for custom fabrication or welding, reducing labor time and complexity during the conversion process. The zinc-plated finish protects against rust in high-heat engine bay environments where standard paint would break down rapidly. Each kit is sold as a pair, providing mounts for both driver and passenger sides of the engine bay.
This kit addresses a specific market: restomod and classic car builders performing LS swaps into early A-Body vehicles. Original rubber isolator mounts and brackets designed for small-block Chevrolet or inline-six engines cannot safely support the weight and vibration characteristics of an LS platform. The HOOKER solution maintains proper driveline geometry, supports engine mass, and isolates vibration without requiring ground-up frame modification or custom welding work.
Engine mount selection directly impacts shift feel, NVH (noise, vibration, harshness) control, and long-term reliability of associated drivetrain and suspension components. Undersized or misaligned mounts lead to excessive engine movement, broken isolation bushings, accelerated transmission wear, and steering feedback issues. HOOKER's application-specific design ensures the LS engine stays where it belongs, maintaining chassis dynamics and drivability standards expected from a properly engineered conversion.
