72-DBMT10001: Better belt grip and improved performance (also works for heavier than stock 26” aftermarket tires).

A simple, effective kit that is primarily developed to help recover power losses and improve performance when using oversized tires. The kit does, however, help even for stock tires for those that use the vehicle in soft terrain or switch tire sizes seasonally.

Larger or heavier tires hurt performance everywhere. Rotating weight and added gearing from larger tires hurt acceleration and speed. This kit helps correct the rate of shift of the belt for the intended use. Improves bottom end performance without further loss of top speed. Throttle response is improved and better back shifting of the belt when the vehicle senses load from soft terrain or hills.

472-DBMT10002: This kit is more specific to very large tire sizes. Developed to help recover power losses and belt performance when using extra-large oversized tires. Larger or heavier tires hurt performance everywhere. The larger the tire size, the more loss incurred from installing them. The rotating weight and added gearing from larger tires hurt acceleration and top speed. This kit improves bottom end performance and improves belt grip without further loss of top speed. Throttle response is improved and better back shifting of the belt when the vehicle senses load from soft terrain or hills. A better clutch recalibration for controlling “rate of shift of the belt” with these tire sizes.

The kit includes new springs for both primary and secondary clutches, as well as a new helix* with a custom ramp that is designed to work with the rest of the kit. There is also a set of new flyweights that are adjustable and built specifically to the application. The instructions include a set-up guide that tells exactly how to set up for different tires and situations.

* The helix and secondary spring in this kit are not the same as in the DBMT 1000-1 clutch kit.
