What does a secondary clutch spring do?

A secondary clutch spring works with your ATV's clutch system to control how the clutch engages and disengages. Changing the spring can help you adjust the engine's RPM range for better performance on different types of terrain or for specific riding styles.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, means the spring's specifications are very consistent from one unit to the next. This leads to more predictable and reliable clutch performance on your vehicle.

What is the load rating of this spring?

This EPI secondary clutch spring has a load rating of 235 lbs when compressed to 1.75 inches, and 135 lbs when compressed to 3.0 inches.
