2022 Pro R 4 Cylinder Stage 1 Lock & Load Kit
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 2 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.
- Kit includes AA ECU flash for 2022 RZR Pro R 4 Cylinder Models **Requires ECU to be sent in for programming** and AA Stage 2 Clutch Kit with primary clutch limiter.
- 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.
- Level 1 Tune: This tune can be run on a bone stock Pro R on 91-93 octane fuel. This tune adds +10-11 RWHP (15-16 crank horsepower) putting you at roughly 240 crank horsepower with just a flash! Our included Stage 2 clutch kit helps belt grip and gain additional low to mid-range power. This tune can be run with an aftermarket exhaust without any issue, but our Level 2 tune is the best option for aftermarket exhaust as it's slightly richer for more power.
- Level 2 Tune: This tune is developed for a Pro R with 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 +16 RWHP peak and a massive +19 RWHP at 38 MPH (This is gaining roughly +25 crank horsepower) putting you at roughly 250 crank horsepower with just a flash and exhaust! Our included Stage 2 clutch kit with this tune really helps the belt to grip and to help drive the extra power to the wheels. Due to how these motors/tuning works, this tune should work with just about any aftermarket exhaust, but was tested and designed with our AA slip-on exhaust (AA header now available!).
- 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 connector
- 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.
- 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.
- If you have any other needs in these tunes, or any concerns; please e-mail!
- Stage 2 Clutch Kit includes: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
- Optional AA custom helix to upgrade your S2 clutch kit to a S3 clutch kit. This is highly suggested as it adds even more acceleration and helps transfer the power to the rear tires. The helix also cuts down on secondary slop/clanking.
- 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
- For more information on our Stage 2 Clutch Kit please follow this link: RZR Pro R 4 Cylinder S2 Clutch Kit

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

Seems to have done a great job.
Size: Full-size Truck, SUV (2-pack)
One of our cars has suffered from rim leaks and was driving me nuts. Constantly being asked by my wife to top off the tires on her car. When I replaced a damaged rim I asked the tire shop to look for the source of the leaks. They said the "alloy" rims had started to corrode and did their best to get them to seal but warned me they would likely leak again. This spring when I removed her snow tires I found 3 of her 4 tires had gone completely flat in storage. The fourth was the new rim which was fine. I considered buying new rims that won't have this problem but wanted to wait until her times need to be replaced. The batteries in the TPMS sensors are getting very low so likely these will need to be replaced as well. I thought to try some sort of sealant. Most of the products I saw were not rated for automotive systems and offered warnings about risk to the TMPS sensors. This seemed to be the only product rated for my application and claimed it would not harm our car's sensors. So I gave it a shot. I ordered the SUV package that came with an injector and two 8-oz bottles. I put 4 oz in each tire per the instructions. Overall the process was easy except the valve core extractor broken on one of the tires. I had to pick up a replacement at a local auto parts store. Also, injecting the sealant creates a small amount of pressure in the tire that, if one doesn't release by drawing out the plunger, will burp a small amount of sealant onto the rims. Fairly easy to clean up with WARM water and easier to avoid after the first experience. Drove the car around at a variety of speeds for 10-15 minutes (had errands to run) and waited to see what happened. Great results. Weeks later and the tires still have the correct pressure. I am not sure how long this will last but hopefully for the remaining life of the tires at least. I took one star off for easy of use / easy to install because the valve core extractor is made of extremely cheap aluminum and I am sure others will have a poor experience with it. Be forewarned and consider buying one before you start jacking up your car and letting the air out of the tires only to find you break the tool on a sticky valve core and are unable to complete the job without a trip to the auto parts store. I'll update this review in about a year to report on the long-term outlook for this product.

It Works!
Size: Full-size Truck, SUV
When I bought my vehicle it didn't come with a spare. I knew what I was in for. I was on my way to an important meeting and as fate would have, the tire pressure indicator reported a flat. I imagined the worst but experienced the best!
The directions said to let all the air out of tire and remove the valve stem core, it seemed like I was making a bad situation worse. Then it said to attach the tube to the stem and squeeze the contents into the tire. I thought "this is never going to work" the fluid seemed too watery to seal anything, but I followed instructions, I reinstalled the valve core and reinflated the tire, and it worked!
I expected it to leak immediately, it didn't. It lasted all day and most of the next day until I could get the tire to the shop. They removed a nail and patched the hole, overall I'm very satisfied, I bought a replacement right away, just in case!

Better than the green goo
Size: Full-size Truck, SUV (2-pack)
Recently, while I was at work, I noticed that I had at some point run over a nail with my car. Normally, you'd take your car to the tire shop and let them plug the hole for you. Well, the only problem was that the nail decided that it was going to poke my tire where the sidewall meets the tread, and most shops will refuse to plug a tire when it's punctured there. Makes sense, it's a liability issue for them, so I can't blame them. That still leaves me with the problem of having a tire with a nail in it. So, I could either replace the tire with either a new or used tire, which is expensive or I can try using a sealant to try and get as many miles out of my tire as I can.
In the past, I had tried using the green goo sealant on nail holes, and while it works to get you 15 miles down the road, that's about it. Now, while TireJect doesn't recommend using their product on punctures on the shoulder of the tire, I decided that I'd give it a try to see if it would work. And as of writing this review, it's been about 10 days since I put TireJect in my tire, and so far, it hasn't leaked any air, despite it not being meant for the shoulder. When money isn't so tight, I'll probably go ahead and replace the tire, especially since there's only about 4/32 tread depth left, but for the time being, I'll keep running it, and hopefully it keeps holding pressure properly like it has been.
Now, as for how easy it is to use, the only tools you will need that aren't provided, is an air compressor to allow you to re-inflate the tire. The kit comes with everything else you will need, including a valve core removal tool and a syringe to add the sealant to your tire. To use this product, you will first need to carefully remove the valve core with the provided tool, careful not to lose the core, since it doesn't come with a replacement core. After that, thread the hose on the syringe on to your valve stem, and then carefully add the required amount of sealant to the syringe. If you accidentally spill some, wipe it off before it dries, so that it doesn't stain anything. From there, just push the goo into the tire with the plunger, adding more to the syringe as necessary. When you're all done, re-install the valve core into the valve stem snuggly, careful not to over-tighten, and air up the tire to the recommended PSI with your compressor. After all that is done, go take a short, slow drive to distribute the sealant, and then recheck your air pressure.

TPMS Compatability is a LIE
Size: Sedan, Crossover, Small Truck
2018 Subaru Impreza, with one tire with a slow leak (about 2 PSI a week) that I couldn't trace.
I bought the "Full-Size Sedan, Small Truck, Crossover" kit (the 6 oz. pouch) based on my tire size, 225/40/18.
After I removed the valve core, attached the dispensing hose and opened the cap, the product would not flow into the tire. I squeezed the pouch, but that only made the product leak out around the valve stem onto the wheel and driveway. I tried rotating the tire so the valve stem was at the top, and and also at the bottom. I even took the wheel off so I could get a fully vertical flow. Nothing worked. I finally gave up after only about half the product was dispensed, and I do think most of it went somewhere other than in the tire.
I reinstalled the valve core, remounted the wheel, plugged in my little lighter socket-powered compresseor, and tried to inflate the tire. And ... NOTHING. The pressure reading on the compressor immediately shot up to over 100 PSI, and it automatically shut off. Tried multiple times, with the same result. I again removed the valve core, and a) no air came out of the tire when I removed it, and b) even with no valve core the compressor still would not pump air into the tire. Clearly the gunk had completely blocked the valve/TPMS.
Fortunately, when I took the tire to Costco (where I'd bought it), they were able to fix the damage I'd done, as well as patching a small nail hole in the tread I hadn't seen (that was clearly the source of the slow leak) for no charge. Since I've already submitted a refund request, ultimately all it really cost me was my time and effort ... and a whole lot of stress.

Forget the gooey stuff, this product WORKS! See UPDATES 1 and 2
Size: Compact Car, Mid-size Sedan
I've had a slow leak in one of my tires for some time. It's a common thing with chrome plated alloy wheels, they get corrosion on the bead area where the tire seals and then you get a slow leak. This was the only product which is water soluble so it's not going to make a permanent mess inside the tire; additionally, it contains tiny bits of Tufsyn which is the material some tires are made from. So it's not just a liquid that is sealing the leak, it's tiny bits of rubber. I was putting 5 or 6 lbs of air in my tire every few days, and I could see that the tire was getting low. I installed this TireJect per the instructions a week ago and the tire appears to be doing great, despite the fact that we've had some very cold weather. (I didn't want to check it with a gauge while it was this cold out because just in case the tire's valve didn't seal all the way; I'll check with a gauge when this cold snap is past.) While I can't say for 100% sure that there is no more leak, I suspect that the leak has been sealed up completely. This is a product unlike the others and I think it's worth the price.
FIRST UPDATE: It has been two months and I haven't had to add any air at all to the tire where I used this product. There was a slow rim leak which was losing about a pound or so per day and it has been totally fixed. The car has sat for several days a few times, including in single digit cold weather, as well as driven regularly otherwise, and the tire hasn't lost any air. I think it's the micro Tufsyn fibers in this product which seal leaks better than some goopy glue stuff other brands are made of. I totally recommend this product!
SECOND UPDATE - it's been eleven months since I added this to my tire with the slow rim leak and I have not had to add air a single time. Not once. THIS STUFF WORKS. Forget the slime and foam and get this.
