4-Pin Crankhub Kit
$649.99Price
Upgrade the factory S55/N55 crank hub with a 4-pin design engineered to help prevent crank hub rotation and timing slip. The factory hub relies on clamping force and friction to maintain its position, which can become a concern on high-torque, tuned, or aggressively driven engines.
The four mechanical pins positively lock the hub to the crankshaft, helping maintain proper crank-to-cam timing under high loads.
