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. A different spring can change how quickly your machine engages or how high it revs before shifting.

What does the 5% tolerance mean for performance?

A tighter tolerance, like EPI's 5%, means the spring's performance will be more consistent and predictable. This leads to more reliable clutch engagement and a smoother power delivery across different units.

Does this spring come with other clutch components?

This product is for the primary clutch spring only. Other clutch components like weights or secondary springs are typically sold separately.
