Better belt grip and improved performance with extra large tires.

A kit developed to help recover power losses incurred from using very large oversized tires. Rotating weight and gearing from big tires hurts acceleration and speed. The larger you go the more negative the effects. This kit improves bottom end performance without further loss of top speed when used in the application and set up as instructed. Throttle response is improved and better back shifting of the belt when the vehicle senses load form soft terrain or hills. This kit helps bring your vehicle back to life after adding big tires.

The kit includes new primary and secondary clutch springs, along with a custom helix, and a set of adjustable flyweight arms.

There is a set up guide in the instructions that tells you exactly how to set up the kit for different tire sizes (29.5 and larger only) and situations.
