What does a primary clutch spring do?

A primary clutch spring, also known as the drive spring, works with your vehicle's clutch system to control how the clutch engages and disengages. It helps determine your vehicle's acceleration characteristics and its maximum engine RPM.

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 crucial for clutch tuning, ensuring that your adjustments have the intended effect on your vehicle's performance.

What kind of riding is this spring best suited for?

This spring allows you to fine-tune your clutch engagement and top RPM to match specific riding styles and terrain demands. You can adjust it to better suit your needs, whether for trail riding, mudding, or work applications.
