Eliminate Crank Hub Failure on Your N55/S55 with RK Autowerks’ 4-Pin Solution Crank hub issues have plagued BMW N55 and S55 engines for over a decade—causing crankshaft spin, timing drift, and costly internal damage.
RK Autowerks answers this problem with a precisely engineered fix: the RK 4-Pin Crank Hub.
CNC machined in-house at RK’s Texas facility and made from heat-treated 4130 Chromoly steel, this crank hub offers unmatched durability and precision.
The 4-pin design prevents the valve timing and oil pump chains from spinning independently, locking the crank hub to the crank nose for rock-solid alignment and long-term reliability—even on high-horsepower builds.
Developed by Raza and the RK team, this hub has been laser scanned for perfect fitment and is a direct replacement for the OEM part.
Whether you're running a stock engine or a heavily modified setup, this upgrade is a must-have for peace of mind and performance.
