Carbahn Autoworks S55/N55 Keyed Crank Hub Kit
The keyed crank hub kit includes the Keyed hub, Crank bolt, Drill, drill fixture, and drill fixture bolt.
The original flawed design allows the timing gear to spin independently from the crank, especially when the motor is modified. Best case scenario the motor needs to be re-timed with new components. Worst case, the valves contact the pistons requiring a complete overhaul. Common symptoms are rough running and camshaft angle deviation faults. This crank hub uses OEM gears and hub machined and pinned to prevent slipping. Metallurgy is superior to most aftermarket sprockets on the market.
Estimated Installation Time: 18 hours
