Repl Starter Drive Chevy 10-Pitch/9-Tooth

The Repl Starter Drive Chevy 10-Pitch/9-Tooth (SS140) is a replacement steel starter drive engineered for the Meziere 400 Series starter systems. This is a direct-fit component designed for builders and engine shops upgrading or servicing high-performance Chevrolet engines with aftermarket starter packages. The 9-tooth drive gear with 10-pitch specification ensures proper meshing with compatible ring gears, delivering reliable engagement every time the starter motor cranks the engine.

Steel construction provides durability and resistance to the thermal and mechanical stress of repeated cranking cycles. The precise 10-pitch/9-tooth geometry is critical for matching the Chevy ring gear profile—incorrect tooth count or pitch will result in gear clash, incomplete engagement, or premature wear. Weighing just 1.79 lbs with compact dimensions (3.45 × 3.35 × 4.75 inches), this drive integrates seamlessly into Meziere 400 Series applications without requiring extensive modification. Buyers should verify compatibility with their specific engine displacement and ring gear before ordering.

This component is intended for engine builders, restoration specialists, and enthusiasts performing Chevy engine swaps or custom starter installations. Whether sourcing a replacement due to wear, upgrading from stock starters, or assembling a complete aftermarket ignition system, a quality starter drive is essential to avoid costly ring gear damage. The SS140 supports the reliability expectations that come with investing in a purpose-built Meziere starter system.

Starter drive selection requires attention to detail—the wrong tooth count or pitch can compromise engine starting performance and cause mechanical failure. Verify the 10-pitch/9-tooth specification matches your ring gear before purchase to ensure proper operation and longevity.
