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** , AA Stage 3 Clutch Kit with primary clutch limiter and butter shift washers, and AA Stainless Full Exhaust (head pipe & muffler).
- Works with all models including ones with Dynamix and/or EVAP models.
- Looking for the best/most badass ECU tuning available for your RZR Pro R? AA's performance tunes are now available to gain horsepower and torque. Through our advanced ECU tuning we are able to modify parameters correctly to gain you the power needed. We are highly experienced in tuning RZRs and this will show.
- The Pro R uses a new Bosch MG1 ECU. Currently no programmers like the PV3 are available and no ETA, so sending your ECU in for a bench flash is the only way to get a great tune.
- Big horsepower gains depending on the level of tune/modifications (see tune descriptions below for more details)
- Much quicker throttle response and power delivery giving a whole new feel to the vehicle
- Throttle by wire limiters disabled
- Fan on/off at 185 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp. The progressive fan also ramps up quicker to keep you running cooler than OEM.
- Speed limiter removed in low and high gears (Most will be able to run over 100 MPH!)
- More throttle % in low gear and reverse
- Rev limit at a safe 8800 RPM (stock is 8650). Ideal peak RPM is 8200-8500 with the flash, but 8800 is for ramp up overshoot/top speed.
- AA's wicked timing curve is safe for the fuel used, but we do a much better job of finding timing limits for ramp up/more torque. Many others simply focus on wide open throttle timing/fueling.
- AA's modified fuel curve will still get decent mileage cruising, but is corrected over the factory lean AFR when needed.
- AA muffler is now available with an electronic cutout option to adjust sound on the fly without having to install or remove a quiet cap.
- Included Level 2 Tune: This tune is developed for a Pro R with our aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over our Level 1. This tune adds +22 RWHP peak and a massive +33 RWHP at 38 MPH (This is gaining roughly +40 crank horsepower) putting you at roughly 265 crank horsepower with just a flash and full exhaust! Our included Stage 3 clutch kit with this tune really helps the belt to grip and to help drive the extra power to the wheels.
- If you're unsure if your Pro-R is an EVAP model or not, check your Emissions Control sticker located on the front driver's side frame rail above the master cylinder. See pictures for location.
- More tunes coming soon!
- *** ECU MUST BE SENT IN FOR PROGRAMMING: Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020 ***
- 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.
- Customer is responsible for shipping to AA, a shipping label is not included in the price
- Programming turnaround will vary, but is normally 1-2 days.
- Express ECU service for US main 48 states only. We'll send you a next day UPS label, and ship your ECU ONLY back via next day. All other pats will be shipped ground unless otherwise specified/selected during order checkout. Keep in mind we cannot guarantee same day programming or control UPS shipping times/delays. We will do everything possible to turn the ECU around as fast as possible.
- When the ECU arrives we'll read your stock file to determine if it's an Evap model or standard, and we'll keep a file folder for your stock/tune files. We'll then flash with the correct AA tune.
- If you ever need to go back to the OEM tune we charge $95 which includes shipping back to you (shipping back for lower 48 US only). Please contact us if you need to go back to your OEM tune.
- MAKE SURE you insure your ECU for $700. AA is not responsible for shipping delays or lost ECUs. While more expensive over Priority Mail or FedEx, UPS has been the most reliable carrier in our experience.
- While express shipping is available on the ECU, express shipping is NOT available for the other items in this kit (the shipping you select in your cart). To safely ship these parts, they must go into 2 separate boxes and shipping will only calculate for one box. If you need the rest of the parts expressed, please message us first. Please note the 5-10 day lead time for production/assembling/kitting of these items.
- 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!
- If you have any other needs in these tunes, or any concerns; please e-mail!
- Stage 3 Clutch Kit includes: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, AA secondary helix, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
- We highly suggest our Revolver Billet Clutch Cover with Tower Lock to strengthen the clutch and provide more airflow for even better cooling
- The only special tool needed with our clutch kit is our Compression Tool #1
- Follow this link for more information on our Stage 3 Clutch Kit
- Follow this link for more information on our full exhaust system: Stainless Head Pipe & Stainless Slip-On Exhaust

- Oh... and get ready for your Pro R to flat out rip!

Product leaks into the cap
Size: 3.4 Fl Oz (Pack of 1), Size: 3.4 Fl Oz (Pack of 1)
The packaging appears to be defective and potentially tampered with. Specifically, the nozzle is a different color from the rest of the tube—one that is not consistent with the brand’s standard packaging (I am familiar with this brand and have purchased it before). Additionally, the cap does not close properly, causing the product to leak into the lid and resulting in unnecessary waste.
This raises serious concerns about the product’s authenticity, quality control, and whether it may have been previously opened or altered.

Tried + tested on Caribbean vacation
Size: 6 Fl Oz (Pack of 1)
First let me start by saying I have an inflammatory condition so I needed a sunscreen that didn’t contribute to making my symptoms worse like many of the other sunscreens with harsh chemicals. This sunscreen is phenomenal! We just got back from a week in the Caribbean sun in Antigua/Barbuda, and I did not burn once! But there are some key things you must know before buying so that you can apply it properly and get the best protection. First, you must shake the can for about 20 seconds before each use. This way it mixes the sunscreen and applies it correctly. If you spray it and it comes out clear you have not shaken it up enough. It should spray solid white. Second, rub it in quickly after you spray it because it dries fast. Note that this does leave a white cast, but it’s not as bad as everyone says. I have light olive skin (half Hispanic, half white) and I tan easily but I also burn easily. When I applied it, it went on white but I just took the time and rub it in really well. The white cast will fade a little once it dries but it will also sit on top of the skin which is helpful to know when you need to re-apply. I applied in the morning about 20 min before getting in the sun. *Apply before putting on your swim suit! If it gets on your swimwear, it will leave white marks*. The sunscreen stayed on through pool and ocean use without rubbing off. I only needed to reapply on the tops of my shoulders once in the afternoon. Also, this is not to say that you won’t burn. While I was in the intense sun, I also spent time in the shade throughout the day just to make sure I was giving my skin breaks from the heat. But for being in the sun like I was, I am VERY impressed with this sunscreen. And for it only being spf 30, it protected me better than expected in the harsh Caribbean sun. I usually come home from vacations with a little burn but absolutely none this time! Just be sure to take time to apply it correctly and you should be good! I’d rather have a slight, minimal white cast than be burnt and miserable. It’s worth it! I’ll be using this stuff from now on.

I am super white and have great skin which is super surprising ...
I just started using this product and I wanted to write because I thought some of the reviews were mixed when I read them. I used to use Zinka's spray but they changed their formula and now it is a greasy mess, that never dries do not buy that, I wrote the company and they do not care. First and foremost this bottle is heavy so I am not sure if the shaker ball is heavy or what but a 6oz bottle should not be this heavy so that might be a marketing ploy, hope I don't run out and just have a shaker ball. I am super white and have great skin which is super surprising as my childcare was being dumped off at the local pool in TX without sunscreen during the summers, but I attribute that to using a zinc based sunscreen for the past 10-15 years. I use this everyday, rain or shine as I live in TX and it never rains long and winter here has sunshine too. I use it on my face, hands and decolletage. Yes, my face, under my make up or not. Here are the issues, this makes a super white paste that does not fade into the skin if you go too heavy. So you have to rub it in and even then there is a whiteness, and I am already a white gal. I too am longing for a day of clear zinc sunscreen. But none on the market I have found that are not an oily mess that cause breakouts. I like the dry texture of this spray, and if I spray a thin layer I do not need to rub, so that is perfect for me on my face as most make up I put over it has spf protection anyways, so no problem there, and this stuff stays on 12 hours or more. I think the cost is high, I used to pay around $10 a bottle for zinka but it was not as heavy as this so I will see how long this lasts. But so far except for the cost and the having to rub it in I really like this product.

My favorite sunscreen
Size: 6 Fl Oz (Pack of 1)
I love this sunscreen and have been carrying a can in my bag all this summer. To address a couple of common complaints:
“It’s not sheer at all”: “Sheer” does not mean the same thing as “clear,” people. This spray is white and absolutely does rub in to be sheer as advertised. It leaves a slight (“sheer”) white tinge after rubbing in, but it’s not super noticeable on my pale skin. It might be more problematic on darker skin tones. (Also, it should be noted that there is literally no such thing as clear mineral sunscreen- you will have to choose between a product like this and a clear one containing endocrine disruptors. I’d rather look a little pasty, personally.)
“My whole family used this and got burned”: You need to shake the can before spraying, as per the instructions. These sprays are made of zinc (the active, protective ingredient) in a liquid suspension. If you spray without shaking the can first, you risk getting all liquid and no zinc particles, and then yes, you will burn. I’m pretty sensitive and this sunscreen has not failed me yet.
“It’s hard to get off”: This is true. It is hard to get off. But why would you want a sunscreen to come off easily?? This stuff is water resistant to an impressive degree. In the evening if it takes a vigorous scrubbing to get it off, I consider the exfoliation a bonus.
Also, my nozzles have worked just fine and the cans last me quite a good amount of time.
