Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.
