Aftermarket Assassins 2024 RZR XP 1000 Stage 1 Lock & Load Kit

Lock and load your 2024 Polaris RZR XP 1000 and get ready for some serious kick!  The 2024 RZR XP 1000 is a fun machine, but Polaris left room for improvement on the table.  This simple kit is the best way to wake up your XP1K 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. 

• Kit includes AA ECU flash for 2024 RZR XP 1000 Models **Requires ECU to be sent in for programming/unlocking** and AA Stage 3 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 XP1K?  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 2024 RZR XP 1000 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 185/180 degrees Fahrenheit (Stock is 205/192) which is just above the thermostat opening temp.
• Speed limiter removed in low and high gears
• More throttle % in low gear and reverse (Stock limits your throttle for torque limitation)
• Rev limit at a safe 9200 RPM (stock is 8800).  Ideal peak RPM @ 55 MPH is 8400-8600 with the flash, but 9200 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 most on higher throttle inputs.
• Level 1 Tune:   This tune can be run on a bone stock XP1K on 91-93 octane fuel.  This tune adds +5 RWHP (6 crank HP) putting you at roughly 120 crank horsepower with just a flash!  This tune can be run with an aftermarket exhaust, but our Level 2 tune is the best option for aftermarket exhaust as it's slightly richer for more power and less heat.
• Level 2 Tune:  This tune is developed for an XP1K with aftermarket exhaust on 91-93 octane.   It has just a bit more timing and a bit more fuel over Level 1.  This tune adds +7 RWHP peak and a massive +9 RWHP at 30 MPH (This is gaining  roughly +10-11 crank horsepower) putting you at roughly 125 crank horsepower with just a flash and exhaust!  Due to how these motors/tuning works, this tune should work with about any aftermarket exhaust, but was tested and designed with our AA slip-on exhaust.
• Looking for race fuel tunes?  We were also, but unfortunately we found no real power increase by adding octane.  Certainly a little extra octane is never a bad thing to keep your ECU from pulling timing, but we tried various attempts to make more power with no results.
• If you're unsure if your XP1K is an EVAP model or not, check your Emissions Control sticker located on the front driver's side frame rail above the front shock. See pictures for location. 
• *** ECU MUST BE SENT IN FOR PROGRAMMING/UNLOCKING:  Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020  ***
• The ECU is located behind the driver seat (rear driver side if 4 seat). Remove the top panel behind the seats to expose the ECU.  Remove the torx bolts and ECU connector
• Customer is responsible for shipping the ECU to AA, a shipping label is not included in the price  **Excludes Express Flash, which includes UPS Next Day Air label to ship ECU to AA
• Programming turnaround will vary, but is normally 1-2 business days.  
• Express ECU service for US main 48 states only.   We'll send you a Next Day Air UPS label, and ship your ECU ONLY back via Next Day.  All other parts will be shipped ground unless otherwise specified/selected during order checkout.  Keep in mind we cannot guarantee same day programming/unlocking 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 and 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.  (This is only for the AA ECU bench flash)
• 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 XP1K 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: Setup/Installation sheet, AA Recoil magnetic adjustable clutch weights, primary spring, primary limiter washer, secondary spring and AA helix.  The initial setup guideline shows the best setups for dunes, mud, or all around trail riding. This also has brief instructions on installing your clutch kit among other important information.
• The 2024 XP 1000 is clutched very odd from the factory.  The vehicle winds out RPM right from the gate and does not transfer any torque until you hit peak RPM.  This is somewhat of a race setup, but really all around it does not work well.  Our kit helps combat this with our helix specifically designed for this model, along with our weights and springs that are all key components in transferring power to the rear tire efficiently.  This is shown on the dyno and felt in real world driving (butt dyno).  The clutch kit also adds huge belt grip and is especially needed when going to larger tires.  The Performance helix gains the most acceleration, while the High Load helix is a little more than stock but less aggressive for excessively heavy/large tires, crawling, or mud riding.
• High Load Helix 1067:  Slightly less aggressive than the Performance helix with good acceleration gains/power transfer over the OEM helix.  Designed to work better for heavier vehicles, heavier tires, heavy sand load or crawling type riding in mind.   Works on 2 & 4 seat models with 30-35" tires or 30-33"  paddles.   Excellent all-around helix!  
• Performance Helix 1068:   Aggressive helix with acceleration/higher horsepower/aggressive fast pace drivers in mind. Works best with a tuned vehicle.  Works on 2 seat models with  30-32" Tires.  Not suggested for 4 seat models.
• The only special tool needed with our clutch kit is our Compression Tool #1
• For more information on our Stage 3 Clutch Kit please follow this link:  2024 RZR XP1K S3 Clutch Kit
• We HIGHLY suggest running our Stryker Belt as we've found it grips much better in the clutches
• We also suggest our Revolver Billet Clutch Cover with Tower Lock for improved strength and airflow
• Have alignment issues? Use our P90X Secondary Clutch Alignment Shim Kit to set things straight
• Highly recommend upgrading to our Heavy Duty P90X Secondary Clutch Rollers
• Oh... and get ready for your XP1K to flat out rip!
