Manufactured from high-strength alloy steel with precise heat treatment, this integrated starter drive features matched gear teeth and one-way locking mechanism. It engages firmly when cranking and releases automatically once the engine starts, protecting the starter from back-driving damage. It is engineered to replace worn, slipping or broken original units, solving common troubles such as starter free-spinning, harsh meshing noise and failed disengagement. Every component is machined under tight tolerance standards for great compatibility and straightforward replacement.
