EPI Clutch Kit

Why EPI Performance Is the Go-To Name in ATV & UTV Clutch Kits

When off-road riders talk about CVT clutch upgrades, one name consistently rises to the top: EPI Performance. Known in the powersports world as The Clutch Guys®, EPI has spent decades mastering the science of power transfer for ATVs and UTVs. Clutch kits are not just a product line for EPI — they are the company's core identity, and that focused expertise shows in every kit they produce.

Over 35 Years of CVT Clutch Engineering

EPI Performance, short for Erlandson Performance Inc., has been developing extreme-duty driveline parts since 1991. What began as a passion project has grown into a globally recognized brand. EPI clutch kits are trusted by more dealers, racers, and off-road enthusiasts than any other aftermarket brand — a testament to decades of real-world testing and continuous refinement.

Each kit is designed and tested by The Clutch Guys in real-world conditions, factoring in tire size, elevation, and terrain type to ensure peak performance right out of the box — no complicated tuning required.

A Clutch Kit for Every Riding Style

One of EPI's greatest strengths in the clutch kit category is the sheer breadth of application-specific options. Rather than offering a one-size-fits-all solution, EPI engineers distinct kit families tuned for different demands:

• Sport Utility Kit — The most popular option, designed for trail riding, light mud, sand, plowing, and hauling. Compensates for power loss caused by oversized tires or added weight, while improving low-end and mid-range acceleration and delivering quicker, crisper backshifts.
• Mudder Kit — Engineered specifically for aggressive mud riding with lug tires. Restores power lost to heavier tires and challenging terrain while increasing low-end torque to keep tires turning in thick mud.
• Sand Dune Kit — Designed and tested for sand dune applications with separate tuning for stock and paddle tires. Helps hold peak power RPM when dune riding and climbing hills.
• Rock Crawler Kit — Optimized for the unique demands of rock crawling terrain, where controlled low-end power delivery is critical.
• Pro Series Kit — A combination of Sport Utility, Mudder, Sand Dune, and Rock Crawler configurations in one package, with adjustable weights and multiple springs for riders who tackle varied terrain or plan to modify their machines over time.

What's Inside an EPI Clutch Kit?

Depending on the vehicle and application, an EPI clutch kit may include a primary clutch spring, secondary clutch spring, helix, and clutch weights — all carefully calibrated to work together for maximum power transfer and throttle response. These components are carefully developed to deliver stronger acceleration, smoother engagement, and improved backshift while protecting your belt and drivetrain from excessive heat and slip.

Wide Vehicle Compatibility

EPI builds clutch kits for an impressive range of makes and models, including Polaris, Can-Am, Kawasaki, Yamaha, Arctic Cat (Textron), CFMoto, Honda, John Deere, Cub Cadet, and Suzuki. Whether you ride a Polaris RZR, Can-Am Maverick, or a utility-focused workhorse, there is an EPI kit built specifically for your machine's CVT system.

For riders who want the confidence of a clutch system designed by specialists — not generalists — EPI Performance clutch kits represent over three decades of focused engineering, real-world validation, and a reputation earned one trail at a time.
