What does a secondary clutch spring do?

The secondary clutch spring works with your clutch to control how power is delivered to the wheels. Changing this spring can alter when your clutch engages and how it shifts, allowing you to better match your ATV's performance to your riding style and terrain.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI adheres to, ensures that each spring performs consistently. This means you get predictable clutch engagement and performance every time you install one, reducing variability.

What is the load rating for this spring?

This EPI secondary spring is rated for 280 lbs of load at 1.75 inches and 160 lbs of load at 3.0 inches. These ratings help determine how the clutch engages and disengages.

Product Details

If you're looking to get more out of your Yamaha 400-700 Kodiak, 450-750 Grizzly, or Viking's clutch system, this secondary spring from EPI is a solid option. It's designed to help you dial in how your clutch engages and what your top RPM can be, making it easier to match your machine to how and where you ride.

EPI makes these springs with good materials and they hold to a really tight tolerance, just 5%, which is the lowest you'll find in the industry. This means you can count on consistent performance every time. At 1.75 inches of load, it's rated for 280 lbs, and at 3.0 inches, it's 160 lbs. This helps change how your clutch grabs and releases power, giving you a more responsive feel on the trail or wherever you're riding.
