We need some info to get you the correct parts inside your clutch. Primary arm options: The primary clutch comes in a 3 arm, 6 arm or 8 arm setup. For non turbo mild setups we recommend the 3 arm as it is lightest and plenty strong.
If you have a big bore or turbo with less up to 15psi use the 6 arm.Making changes to the clutch that seem insignificant can have huge consequences to horsepower, torque, and belt life. Hang with me for a minute here. Most cars shift through different gears as you accelerate. That means it can stay in the optimal RPM range all the way until you hit the mechanical limitations of the clutch.
But the mechanics that go into that process are a little more complicated.
The primary clutch looks kind of like a couple dinner plates smashed together with some extra hardware on the backside of one. When your foot is off the gas, the clutch is fully open because the primary clutch spring holds it open. As soon as you touch the gas, the RPMs rise and the clutch starts to close.
This makes the two sheaves move closer together and pinch the belt. That pinch is what starts driving the belt and driving the rest of the machine. This is where the magic happens. As the sheaves move closer together, the belt moves further out on the clutch, like a chain on a bike moving to larger gears. Except, because the clutch is CVT, that change is smooth.

This is where your clutch arms and clutch springs come in. The primary clutch spring is trying to keep your clutch open with all its might. The clutch arms fight against the spring by using centrifugal force to try to close the sheaves.
Clutch arms at different weights change the rate that these sheaves close. There are lots of little details that make this run smoothly like the material used in the rollers that arms push against, the bushing in those rollers, the bushings in the arms that allows them to pivot, and the machined curve of the top of the arm.
STM clutch kit for RZR Primary and secondary
Polaris gets those details right so all that matters after that is spring rate and arm weight. When we make a clutch kit for Polaris vehicles, all we do to the primary clutch is change the spring out for a harder or softer spring and change the clutch arms out for a different weight. Sounds simple right? Too stiff and your clutch stays open too long, which means your RPMs will be over the optimal range before you even start moving.
Too soft and your clutch will close quickly, so you might never hit the optimal RPM range at all. We get close by picking a specific spring, but we fine-tune it with the clutch arms.
Our clutch arms have three separate weight points along them. This lets us be very precise. After we get the spring we think we need, we slap some weights onto the clutch arms—the same weights we send with our clutch kits for you to use—and give the machine a pull on our in-house dyno.
The dyno short for dynamometer measures horsepower, torque, and RPM over time. The cool part is that because of the three weight locations on our clutch arms, we can change the behavior of the clutch when it first engages, when it fully closes, and everything in between. If it over-revs too early, pull some weight off the outmost spot. If the torque dips in the middle, then we can add a little weight to the middle.
The clutches might vary slightly from year to year, but they all operate basically the same.
