Prevent costly engine damage to your BMW with S55 or N55 engine with the Evolve pinned crank hub.
The original crank hub can slip or rotate on tuned and sometimes even stock cars. In the best case, the engine has to be retimed; in the worst case, pistons and valves make contact. The two-piece Evolve crank hub with 4 pins into the original crankshaft permanently solves this weak point.
