Polaris 400 Xplorer, Xpress & Sportsman Clutch Kit for 27–28 Inch Tires – Low Elevation | EPI Performance Sport Utility Clutch Kit
The EPI Performance Low Elevation Sport Utility Clutch Kit is designed to restore lost power and improve throttle response for 1993–2002 Polaris 400 Xplorer, Xpress, and Sportsman models running oversized 27–28 inch tires. Larger tires increase drivetrain resistance and rotational mass, which can reduce acceleration and create sluggish throttle response. This precision-engineered clutch kit recalibrates the clutch system to compensate for the additional load created by oversized tires.
Optimized for riding elevations between 0 and 3,000 feet, this sport utility clutch kit enhances power delivery by improving low-end torque and midrange acceleration. The kit also provides quicker clutch backshift, allowing your ATV to respond faster to throttle input and deliver smoother performance across a wide range of riding conditions.
Whether you’re trail riding, tackling occasional mud or sand, or using your ATV for work tasks such as plowing and hauling, this clutch kit helps maintain reliable performance while reducing belt slip and clutch heat. The result is improved drivetrain efficiency and longer belt life.
