What does a primary clutch spring do?

A primary clutch spring, also known as a drive spring, works with your vehicle's clutch system to control how the clutch engages and the maximum engine RPM. Changing it can alter your vehicle's acceleration and top-end speed characteristics.

What is the significance of the 5% tolerance?

A 5% tolerance means the spring's performance characteristics will be very close to its stated specifications. This tight tolerance ensures consistent and reliable clutch engagement, which is important for predictable vehicle performance.

What do the load specifications mean?

The load specifications (1.25 in. load - 200 lbs and 2.5 in. load - 40 lbs) indicate how much force the spring exerts at different compression lengths. These figures help determine how the spring will affect your clutch's engagement point and overall performance curve.

Product Details

This product is a single EPI Primary (Drive) Spring, color-coded Teal, designed to adjust the performance of your ATV or UTV's clutch system. It allows you to fine-tune how your clutch engages and the maximum RPM your vehicle can reach, helping you match your machine's performance to different riding styles and terrains.

EPI makes these springs with well-built materials and holds them to a very tight 5% tolerance, which is the lowest in the industry. This means you get consistent and reliable performance every time. At 1.25 inches of load, it applies 200 lbs, and at 2.5 inches of load, it applies 40 lbs. This spring is a popular choice for riders looking to get more out of their clutch setup.
