EPI Performance Low Elevation Sport Utility Clutch Kit for 2009–2010 Polaris Sportsman 550 (27–28 Inch Tires)

Upgrade your 2009–2010 Polaris Sportsman 550 for improved performance with the EPI Performance Low Elevation Sport Utility Clutch Kit (WE436811). Specifically engineered for ATVs running 27–28 inch tires and operating at elevations between 0–3000 feet, this clutch kit restores lost power and responsiveness caused by oversized tire upgrades.

Larger tires increase drivetrain load and can cause sluggish acceleration and reduced throttle response. This precision-tuned clutch kit compensates for that added weight, delivering stronger low-end and midrange acceleration, quicker backshift, and improved overall drivability. It’s EPI’s best all-around clutch kit for riders who use their ATV for both recreation and work.

Why Choose the EPI Sport Utility Clutch Kit?

Oversized tires increase rotational mass and can reduce the performance of your ATV’s factory clutch setup. The EPI WE436811 clutch kit recalibrates your CVT system to maintain proper engine RPM, restore acceleration, and improve throttle response under load.

If you’re running 27–28” tires and want reliable, all-around ATV performance for work and trail riding, this heavy-duty clutch upgrade delivers improved torque, smoother engagement, and enhanced drivetrain durability.
