What does a primary clutch spring do?

The primary clutch spring works with the clutch weights to control when your ATV or UTV's drive clutch engages. Changing the spring allows you to adjust the engagement RPM and the engine's top RPM, tailoring the power delivery to your specific riding needs.

Why is the 5% tolerance important?

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

What are the load ratings for this spring?

This EPI primary spring has a load rating of 45 kg at 2.25 inches and 72 kg at 1.25 inches. These figures help you understand how the spring will behave under different load conditions within the clutch.
