What does a primary clutch spring do?

A primary clutch spring helps control when your vehicle's clutch engages and what its maximum engine speed (RPM) is. Changing it can adjust how your machine accelerates and performs at higher speeds.

Why is the 5% tolerance important?

A strict 5% tolerance means the spring's performance will be very consistent and predictable. This is crucial for clutch systems where small variations can affect engagement and overall performance.

What is the load rating of this spring?

This EPI spring has a load rating of 132 lbs at 2.25 inches, 182 lbs at 1.25 inches, and 120 lbs at 2.5 inches. These figures help determine how it will affect your clutch's engagement characteristics.
