What does a primary drive spring do for my ATV?

The primary drive spring is a crucial part of your ATV's clutch system. It helps control when the clutch engages as you accelerate and influences the maximum engine speed (RPM) the clutch will allow, letting you tailor performance to your needs.

Why is the 5% tolerance important for this spring?

A tight tolerance, like the 5% EPI adheres to, means the spring's performance will be very consistent and predictable. This is important for reliable clutch engagement and ensuring your ATV performs as expected under various conditions.

Does this spring come with any other clutch components?

This product is for the EPI Purple Primary Drive Spring (Part# DRS17) only. Other clutch components, if needed, would be sold separately.
