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-Up RZR Pro R 4 Cylinder Models **Requires ECU to be sent in for programming** and AA Stage 2 Clutch Kit with primary clutch limiter and butter shift washers.
  • 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.   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 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!

Robust pipe & fittings with a beautiful, smooth black finish
Size: side table leg
This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.

Good DIY Pipe Legs but Powder Coat Quality Lacks
Size: side table leg, Size: side table leg
These industrial style pipe legs make building a DIY end table easy and the kit saves a trip to the hardware store. The fittings go together normally and assembly is simple. Comes individually wrapped. My main issue is the powder coating looks and feels cheap and rubs off easily. The pipes already had marks from touching each other from unboxing. If you do not mind some wear on the finish over time this is a decent purchase. The metal at the hardware store will be thicker and more durable but will cost more. I’d recommend based on ease of having a kit and it being delivered saving me a trip.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top. The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.) If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box. Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT! The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe. While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year. So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.
