DBW 570EBS - Sportsman 570 EBS 28" + tires - 2014-15,18-19 only

Sportsman 570 EBS 28" + tires. (* and some heavy 27" tires for mud applications) - 2014-15,18-19 only (2016,17 have different secondary clutch)

Designed to correct the shift pattern for larger tires. It is physics...larger tires, the resulting gearing, and added rotating weight hurt acceleration. People who have tested tire sizes know that even a slightly larger or heavier tire hurts performance and speed. Proper clutch calibration can help recover much of that loss and improve belt grip and bottom end performance. This kit includes a new primary spring and the Quick Adjust flyweights and hardware, along with a different secondary spring. The instructions and "set up guide" include settings for all tire sizes and terrain.     

* using a heavier secondary spring when not necessary can affect top speed.
