Polaris Sportsman 400 4×4 Sport Utility Clutch Kit for Stock Tires
The EPI Performance Low Elevation Sport Utility Clutch Kit WE414008 is engineered to improve
the overall performance and responsiveness of your Polaris Sportsman 400 4×4. Designed for
ATVs equipped with stock tires and operating at elevations between
0–3000 feet, this clutch kit optimizes the CVT clutch system to deliver
stronger acceleration, smoother power transfer, and improved throttle response.
This all-around sport utility clutch kit is ideal for riders who use their ATV
for both work and recreational riding. Whether you’re navigating trails, hauling gear,
plowing snow, or tackling occasional mud and sand terrain, the kit recalibrates clutch
engagement to keep your engine operating in its optimal power band.
