What is the purpose of the Vernier sprocket in this belt drive system?

The infinitely adjustable Vernier sprocket allows for extremely precise tuning of your camshaft timing. This ensures your engine's valves open and close at the exact moment needed for optimal performance, especially in high-RPM or high-compression scenarios.

How does this belt drive system help with valve train stability?

This system is engineered to absorb crankshaft harmonics. By dampening these vibrations, it helps prevent instability in the valve train, which can otherwise lead to performance loss and potential damage.

Does this kit include everything needed for installation?

The COMP Cams Hi-Tech Belt Drive System includes the belt, idler, Vernier sprocket, camshaft thrust adjustment system, and double-lip seals. It's recommended to consult the manufacturer's installation instructions for any additional hardware or specific procedures required for your application.
