What is the purpose of clutch weights?

Clutch weights, also known as flyweights, are a key part of your ATV's continuously variable transmission (CVT). As the engine RPMs increase, centrifugal force causes these weights to move outward, which in turn shifts the clutch to engage the next gear ratio. The weight and placement of these components directly influence when your clutch engages and disengages.

What material are these clutch weights made from?

These EPI clutch weights are precision-machined from billet tool-steel. They are then heat-treated and plated to help them resist wear and extend their service life.

Does this set include everything I need for installation?

This set includes three clutch weights, each weighing 73 grams, along with the necessary bushing for installation. It's designed to be a direct replacement for the OE Polaris 36 series weights.

Product Details

If you're looking to fine-tune the performance of your 2021-2023 Polaris 570 Sportsman's clutch system, these S57 Series Weights from EPI are a solid option. These weights are designed to replace the stock Polaris 36 series weights, allowing you to adjust how your clutch engages and disengages at different RPMs. Getting the right weight can make a noticeable difference in how your machine accelerates and handles power.

EPI machines these weights from billet tool-steel, which is a strong material chosen for its durability. They're also heat-treated and plated to help them resist wear over time, meaning they should hold up well through regular use. This set comes with three weights and includes the necessary bushing for installation, making it a straightforward replacement for your existing clutch components.
