What does a primary clutch spring do?

The primary clutch spring works with the clutch weights to control when your vehicle's transmission engages and disengages. It helps determine your vehicle's low-speed engagement and how it shifts through its RPM range.

Why would I want to change my primary clutch spring?

Changing the primary spring allows you to adjust your vehicle's clutch engagement point and top-end RPM. This can improve throttle response, help you match gearing to larger tires, or optimize performance for specific riding conditions like mud or trail riding.

How tight is the tolerance on these springs?

EPI manufactures these springs to a very strict 5% tolerance, which is noted as the lowest in the industry. This ensures consistent and predictable performance from the spring.

Product Details

This is the EPI Primary Clutch Spring, part number PATV24, designed for 2016 and newer Polaris Ranger XP, Crew, Xpedition, and RZR PRO R, S, and XP Turbo models. This spring is a key component in your vehicle's clutch system, helping to manage how your engine's power gets to the wheels. By changing out the stock spring with this one, you can adjust when your clutch engages and the maximum RPM your engine reaches, letting you tailor the performance to how and where you ride.

EPI makes these springs with good materials and holds them to a very tight 5% tolerance, which is the lowest in the industry. This means you get a consistent and reliable performance every time. For example, it has a 159 lb load at 2.25 inches and a 245 lb load at 1.25 inches, with a 138 lb load at 2.5 inches. This precision helps ensure your clutch behaves predictably, whether you're crawling over rocks or hitting open trails.
