What does a secondary clutch spring do?

The secondary clutch spring works with your UTV's clutch system to control how engine power is transferred to the wheels. It helps determine at what RPM the clutch engages and how it performs at higher engine speeds, allowing for customization to riding style and terrain.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, means the spring's specifications are very consistent. This leads to more predictable and reliable clutch performance, ensuring the power delivery matches your expectations.

Does this spring come with any other clutch components?

This product is for the secondary clutch spring only. Other clutch components, such as weights or primary springs, are sold separately and may be needed for a complete clutch tuning setup.
