What is the main advantage of the infinitely adjustable Vernier sprocket?

The infinitely adjustable Vernier sprocket allows for absolute timing accuracy. This is critical for optimizing performance in high-compression, high-RPM engines and ensures your valve timing is set precisely.

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

The system is designed to absorb crankshaft harmonics, which are vibrations that can lead to valve train instability. By reducing these harmonics, the belt drive helps maintain consistent valve train operation and prevents performance loss.

Does this kit include everything needed for installation?

The kit includes the belt drive, Vernier sprockets, idler system, double lip seals, and the unique camshaft thrust adjustment system. It is designed as a complete timing solution, but always refer to the manufacturer's installation instructions for any additional hardware or specific procedures.

Product Details

The COMP Cams Hi-Tech Belt Drive system uses an infinitely adjustable Vernier sprocket, allowing for absolute timing accuracy. This is crucial for getting the most out of your high-compression engine, especially when pushing it to higher RPMs. The system is built for extreme applications, featuring a unique belt idler system designed to significantly reduce belt flap across the entire RPM range. This not only contributes to a quieter operation but also helps maintain consistent timing under stress.

Beyond just timing, this belt drive is engineered to absorb crankshaft harmonics. This is a notable benefit because it helps guard against valve train instability that can rob your engine of performance. The design also incorporates a unique camshaft thrust adjustment system, eliminating the need for shims and simplifying setup. Double-lip seals are included to ensure long life and maintain maximum crankcase vacuum, which is important for overall engine health and efficiency. This kit is a solid option for serious street performance builds and dedicated race applications where precise timing and durability are paramount.

This Hi-Tech belt drive is designed to fit a wide range of Chevrolet and Oldsmobile engines with a raised cam location, including popular models like the 1987-1994 Chevrolet Blazer, 1988-1995 Chevrolet C1500, and 1987-1992 Chevrolet Camaro. It's a comprehensive kit for those looking to achieve absolute timing accuracy and improved valve train stability in their performance build.
