What does a primary clutch spring do?

A primary clutch spring, also known as the drive spring, works with your machine's clutch system. It helps control when the clutch engages and how it performs at different RPMs, allowing you to tune it for your specific needs.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, means the spring's performance is very consistent and predictable. This is crucial for clutch tuning, ensuring you get reliable engagement and performance every time you ride.

What is the difference between the 60mm and 32mm load ratings?

These ratings indicate the spring's resistance at different compression points. The 60mm load is measured when the spring is compressed to 60mm, and the 32mm load is measured at 32mm compression. Both figures help define the spring's stiffness and engagement characteristics.

Product Details

EPI is a well-known name in the ATV and UTV world, especially for their drivetrain components. This primary drive spring, part number CVT2, is designed to help you dial in your machine's clutch performance. If you're looking to adjust how your ATV or UTV engages or want to better match your clutch to your specific riding style and the terrain you tackle, a spring like this is a key piece of the puzzle.

What sets these springs apart is how precisely they're made. EPI holds them to a very tight 5% tolerance, which is the lowest you'll find in the industry. This means you get a consistent and reliable performance every time. For example, this spring has a 60mm load of 300 Newtons (about 68 Lbs) and a 32mm load of 600 Newtons (about 135 Lbs). This level of accuracy helps ensure your clutch engages and performs predictably, making a noticeable difference on the trail or in the field.
