What does a primary clutch spring do?

A primary clutch spring controls when your clutch engages and how the engine's RPM changes with speed. Adjusting this spring allows you to fine-tune your vehicle's acceleration and top-end performance to better suit your riding style or the terrain.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, ensures that the spring performs consistently. This means you get predictable clutch engagement and RPM behavior, which is crucial for reliable performance, especially in demanding off-road conditions.

What are the load specifications for this spring?

This EPI primary spring has a load of 105 lbs at 2.25 inches, 280 lbs at 1.25 inches, and 65 lbs at 2.5 inches. These figures help in understanding how the spring will behave under different compression levels within the clutch.

Product Details

If you're looking to dial in your ATV or UTV's clutch for a specific riding style or terrain, this EPI Primary Drive Spring is a solid option. It lets you adjust how your clutch engages and the top RPM your engine can reach, giving you more control over your machine's power delivery. This is especially helpful if you've modified your vehicle or if you're tackling challenging trails where precise clutch action makes a big difference.

EPI makes these springs with good materials and holds them to a very tight 5% tolerance, which is the lowest in the industry.

The spring has a 105 lb load at 2.25 inches, a 280 lb load at 1.25 inches, and a 65 lb load at 2.5 inches, allowing for specific tuning capabilities.
