***PLEASE CONTACT 720-600-5743 FOR ORDERING HELP WITH OPTIONS SUCH AS TUNING OPTIONS, CLUTCH OPTIONS, GAUGE OPTIONS ETC***


 Works with all models including ones with Dynamix and/or EVAP models

• Lock and load your Polaris Pro R 4 cylinder and get ready for some serious kick!  The Pro R is an awesome machine, but Polaris left a ton of room for improvement on the table.  This simple kit is the best way to wake up your Pro R as it comes with our proven ECU flash. The ECU flash adds some amazing horsepower from low end to high end RPM and really gives your machine that "snap" you're looking for.  Our AA Stage 3 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup and poor belt grip.  We finish out the kit with our AA RZR Pro-R full exhaust (head pipe and muffler) and it's just what your machine needs!  We set out to produce an exhaust that looks great, sounds great and has adjustable sound levels while producing the most power possible.
• Kit includes AA ECU flash for 2022-Up RZR Pro R 4 Cylinder Models **Requires ECU to be sent in for programming/unlocking unless choosing to purchase ECU outright**

• • The ECU is located behind the passenger (rear passenger if 4 seat) seat. Remove the top panel behind the seats, then remove the fabric panel to expose the ECU.  Remove the Torx bolts and ECU connectors.
• Why AA tunes over others?  We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR.  Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time.  We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs.  Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres.  It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.   We left nothing on the table on the Pro R bolt-on parts, if others claim more power/gains for the same mods use caution in believing it!

•  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
• Stage 3 Clutch Kit includes: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, primary clutch limiter, AA secondary helix, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
