Edelbrock Accu‑Drive camshaft gear drive kit for small‑block Chevy engines replaces the timing chain with a precision compound gear drive to deliver accurate timing control and eliminate chain stretch. The floating main idler optimizes load sharing between crank and cam gears. Billet SAE‑1144 steel gears with induction‑hardened, shaved teeth and hardened idler pins provide durable, precise operation while remaining compatible with standard camshafts.
