What does a primary clutch spring do?

The primary clutch spring works with the clutch weights to control when your vehicle shifts into a higher gear. Changing the spring allows you to adjust the engagement speed and the maximum RPM your engine reaches, tailoring the power delivery to your needs.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, ensures that each spring performs consistently. This means you get predictable clutch engagement and performance, which is crucial for off-road riding where responsiveness matters.

What are the load specifications for this spring?

This EPI Gold primary spring has a load of 135 lbs at 1.25 inches, 47 lbs at 2.25 inches, and 25 lbs at 2.5 inches. These figures help determine how the clutch will engage and perform under different load conditions.
