EPI Performance Driveline: Engineered Where It Counts

When it comes to driveline components for ATVs, UTVs, and snowmobiles, few names carry the weight of EPI Performance. Founded in 1991 — originally as Erlandson Performance — with the primary goal of building clutch kits for snowmobiles, UTVs, and ATVs, EPI has spent more than three decades refining what it means to build a driveline part that truly performs in the real world. Headquartered in Minnesota, EPI Performance has become a trusted name in the ATV and UTV aftermarket.

A Driveline Lineup Built for Severe Conditions

EPI Performance designs, develops, and manufactures high-performance CVT clutch calibration kits, drive belts, and other quality driveline replacement components for the UTV market. Over time, the brand expanded well beyond clutch kits: EPI also offers high-quality replacement driveline parts such as wheelshafts, U-joints, CV joints, front end and suspension parts, brakes, and more.

One of EPI's most recognized driveline offerings is its Severe Duty drive belt line. EPI Performance built its reputation by delivering real-world results, specifically through its Severe Duty drive belt line. Their Severe Duty line of belts is specifically designed to hold up to all of the major modifications that riders are making to their machines. For riders who have upgraded to larger tires, added a lift kit, or tuned for more power, these belts are engineered to handle the extra heat and stress that a stock belt simply cannot manage.

On the clutch side, the original clutch is good for a stock vehicle, but if you upgrade your machine with bigger tires or add more power to hit the trail, your clutch should be recalibrated to get the most out of your modifications. Every EPI clutch kit is tested in real-world riding environments to ensure it is reliable and efficient and ready for installation right out of the box, without fancy tuning or complicated parts.

Real-World Testing, Not Just Bench Testing

What separates EPI from the competition in the driveline space is a commitment to field validation. EPI Performance takes pride in its meticulous engineering and in-house testing to deliver top-tier performance where it matters most — every product is designed from the ground up to maximize performance, while grueling in-house testing ensures every product delivers. EPI engineers put in countless hours in the dirt and snow dialing in clutch kits, personally testing all of the machines they make kits for and putting them through real-world conditions.

The lineup of EPI Performance springs includes primary and secondary springs, all made from high-tensile chrome silicon alloy and capable of withstanding the harshest riding conditions. Combined with axles, CV joints, and U-joints engineered to the same standard, EPI's driveline catalog covers the full range of components that transfer power from engine to wheel — every piece built to handle the abuse of off-road riding.
