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.

If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Kit includes

Turner Motorsport WPC-Treated Race Series Rod Bearing Shells (8) Hardware for Oil Pan & Oil Sump Oil filter Liqui-Moly Molygen 5W-40 (6L) Drain Plug Turner Motorsport Oil Reminder Sticker Oil pan gasket RedLine assembly lube (4 oz.)
