Installation Kit-Gm Shif

The Installation Kit-GM Shift is a complete mounting and hardware assembly designed for classic automatic transmission builds, specifically engineered to simplify shifter installation on Powerglide, TH350, and TH400 transmissions. This kit addresses a critical need for hot rodders, classic car restorers, and transmission technicians who require a straightforward solution for secure shifter attachment. By consolidating all necessary arms, brackets, and fasteners into one package, this kit eliminates the guesswork and multiple sourcing trips that traditionally accompany transmission upgrades.

Constructed from durable steel and finished with cadmium and zinc oxide plating, the Installation Kit-GM Shift provides corrosion resistance and long-term structural integrity in engine bay environments. The cadmium-zinc coating protects against salt spray, moisture, and thermal cycling—critical factors for reliability in both street and performance applications. The kit includes pre-engineered arms and brackets that mate directly with factory and aftermarket shifter mechanisms, ensuring proper cable geometry and smooth shift engagement. Steel construction delivers the rigidity necessary to maintain precise shift positioning under repeated operation and road vibration.

This kit is ideal for builders working with Chevy Powerglide, TH350, and TH400 transmissions—the most common platforms in classic muscle car and hot rod restorations. Installation requires basic mechanical skill and standard hand tools; all hardware is included to eliminate trips to the fastener bin. The compact 6.9 x 1.4 x 8.9 inch footprint and 0.9 lb weight make it easy to transport and handle during assembly. Whether you're completing a frame-off restoration or upgrading an existing drivetrain, the Installation Kit-GM Shift streamlines the process and ensures a professional, reliable result.
