What is the main benefit of using an EPI primary drive spring?

This spring allows you to fine-tune your vehicle's clutch engagement and top RPM. This helps you match the clutch performance to your specific riding style and the terrain you're tackling.

How does the 5% tolerance benefit my vehicle?

A strict 5% tolerance means the spring's performance will be very consistent and reliable. This helps ensure predictable clutch engagement and consistent top-end RPM.

What are the load ratings for this spring?

The spring is rated for a load of 220 lbs at 1.25 inches and 115 lbs at 2.5 inches. These figures help indicate how the spring will behave under different load conditions within the clutch system.
