2022-25 Polaris Pro R 4 Cylinder Secondary Clutch

Product Description

Fits all 2022-25 Pro R 4 Cylinder models

• For those looking to replace their factory 2022-Up Pro R 4 Cylinder P90X HD secondary clutch.  Clutch comes with AA heavy duty rollers installed, which are machined in-house from the highest quality material.  Available in OEM setup (OEM helix & spring) or loaded with AA helix, spring and butter shift washers.  If choosing loaded with AA helix/spring,  you must already have primary adjustable clutching.  Contact us if you need to order primary clutching or see the appropriate S4 clutch kit if a replacement primary clutch is also needed.

Benefits of clutches loaded with AA components:

• The Pro-R comes with the biggest CVT clutch ever fitted on a UTV so far. It has unmatched cooling/airflow to keep the longer belt cool, and some great features. However, this large diameter P90X clutch system still has some flaws.  The biggest problem with Pro R clutching is they do not have enough belt grip.  Just like the Pro XP/Turbo R/'21+ RZR Turbo models, the secondary spring is too soft from the factory, but just adding a stiffer spring is not the correct solution.  It's the combination of parts that adds correct belt grip.  Our kits help combat this with a custom AA helix and stiffer secondary spring yet for even better belt grip.  We go from seeing a ton of black belt marks on the secondary, to almost nothing during long wide open throttle abuse testing.  Our Clutch kit on the Pro-R ramp up RPM faster for better acceleration out of the 4 cylinder motor, making them accelerate much faster and quicker response.  After many tests to hold consistency/RPM run to run, we gained nearly 7 RWHP of ramp up power at roughly 40 MPH over the OEM helix/S2 clutch kit!  This shows us what we felt when driving, the OEM helix is not transferring the torque of the big 4 cylinder.
• Kits work great with both stock or modified machines
• Works well with tire sizes 32" to 37" and paddles 30" to 33".
• If running larger tires than listed or gear reduction, please let us know before ordering.
• A must-have when tuning your RZR Pro R to properly transfer the power to the wheels and prevent even more belt slip
• A must-have when running larger tires or paddles
• Wicked throttle response when on & off the throttle
• More efficient power transferred to the wheels
• More consistent clutch/vehicle performance
• Cooler running belt temps (especially when running larger tires or paddles!)
• Longer belt and clutch life.  This kit allowed us to run on 1 belt in a 350 mile wide open/high speed Iceman race and had more life left.  Others with OEM clutch or other kits had belt issues.
• The AA helix has MUCH less roller/ratcheting noise when going from load to unload on the driveline.  Our role pocket is smaller and without the EBS notch (don't worry they still have great engine braking, especially in low).  This also helps extend secondary clutch roller life.
• We offer two clutch kits:
  • Standard Load: The Standard Load clutch kit is meant for stock or near stock size tires and is the one for most fast pace riders or racers. If crawling with a 2 seat model on 34-35" tires we recommend the High Load setup. You'll sacrifice some acceleration but have much better low end belt grip for less belt slip.
    • 2 Seat Models: 32-35" dirt tires or 30-32" paddles
    • 4 Seat Models: 32-33" dirt tires or 28-30" paddles
  • High Load: The High Load clutch kit is meant for those with larger tires or riding style is mostly low speed crawling
    • 2 Seat Models: 36"+ dirt tires or 33"+ paddles
    • 4 Seat Models: 34"+ dirt tires or 32"+ paddles
