VTT's SplineLock technology utilizes high tolerance machined splines that press into the crank, securely locking the hub in place to prevent any slippage. These splines are designed to withstand rotational forces, driving the hub deeper into the crank when faced with situations that would typically cause a stock hub to slip.
VTT has dedicated months to testing and retesting this innovative design, using over 10 different samples to ensure the highest quality and performance. The result is a crank hub solution that provides unmatched reliability and durability for your S55 engine.
The VTT "Spline Lock" Crank hub is a top choice for those dealing with spun crank hub problems. While the installation process may be involved and complex, the benefits far outweigh the effort required. This solution is particularly recommended for those who have modified their engines, engage in regular track use, or plan to keep their M2C/M3/M4 after the warranty expires.
It's important to note that the installation of the VTT SplineLock Crank hub will involve tearing down a good portion of the S55 engine to access the crank hub. While it may not be a quick 8-hour job as previously claimed, the labor involved is significantly less than other keyway-based solutions.
Spun crank hubs (SCH) have been a growing concern for S55 engine owners, with failures reported on both modified and stock platforms. To prevent this issue and ensure the longevity of your engine, investing in a reliable solution like the VTT solution is highly recommended.
