Evolve Pinned Crank Hub Upgrade for BMW S55 and N55 Engines
Stop BMW crank hub slip before it starts. The Evolve 2-piece 4-pin pinned crank hub is the proven crank hub fix for BMW S55 and N55 engines, delivering reliability, durability and peace of mind on tuned and stock cars. Ideal for BMW F87 M2 Competition, F80 M3, F82 M4, F83 M4 and F87 M2 N55 owners looking for a permanent S55 crank hub solution that protects your engine and preserves your performance investment.
Why upgrade your BMW S55 or N55 crank hub
The factory crank hub on S55 and N55 engines is known to slip or spin under load, especially on tuned cars and sometimes even on completely stock cars. When timing slips, the best case is an engine retime. The worst case is piston to valve contact leading to a costly engine rebuild. The Evolve Pinned Crank Hub fix eliminates this weak point with a keyed 4-pin interface for secure drive and consistent timing.
