EPI Clutch Kit WE437433 | Polaris RZR XP 1000 2017–2023 | 30–32” Tires

EPI Clutch Kit | Part# 23-3136 | WE437433

The EPI WE437433 Clutch Kit is designed for Polaris RZR XP 1000 models running oversized tires at 3,000–6,000 feet of elevation. When larger tires are added to a UTV, the extra rotating weight can reduce throttle response, slow acceleration, and increase belt heat. This clutch kit helps bring back the low-end pull, midrange response, and crisp backshift needed for trail riding, work use, occasional mud, sand, and general sport utility riding.

This is a strong all-around clutch upgrade for RZR owners who have moved to larger tires and want better drivability without building a full race-only setup.

Why Upgrade Your Clutch Kit?

Oversized tires can make your RZR feel sluggish off the bottom and harder on belts. The EPI WE437433 clutch kit is designed to help correct clutching for larger tires, giving the machine better response, improved acceleration, and a more efficient power delivery for real-world riding conditions.
