2021+ Sportsman 570 EBS/Trail - oversized tires. not for standard non engine brake models.

(this kit fits the 21 and newer EBS clutches on most models with power steering and EBS)

The 2021 Trail/EBS versions come with clutching that is ok for stock tires and huge gains will not be made with clutching the vehicle if you retain stock tires. This kit is a re-calibration kit for oversized tires and primarily focused on 27-28” tire sizes.

There is good improvement to be made with proper clutching (compared to stock clutching) for oversized tires.
The flyweights in this kit are adjustable and the set up guide shows you how to set up for different tires and terrain. Dalton “Quick Adjust” flyweights allow you to add or subtract grams without even removing the flyweights from the clutch.
There are even settings included in the instructions for set up of the kit for stock tires so that easy adjustment can be made if you go back and forth from stock tires to larger ones on different seasons, or even if you use stock tires in power robbing situations like sand dunes or higher elevations.
