Aftermarket Assassins '13-'22 Polaris RZR 570 Stage 1 Lock & Load Kit

Get ready, your RZR 570 is about to transform!  This simple to install lock and load kit delivers big horsepower and wicked acceleration!

• Kit includes: AA tuned Powervision ECU tuner, S1 Recoil clutch kit (primary weights & primary spring)
• If you are looking for an easy to use ECU tuner loaded with the most badass custom tunes on the market, you've found it!  This DynoJet Powervision is a very simple, yet effective device that programs your ECU in a few minutes, and easily allows you to switch between tunes, or return to the factory tune.  The Powervision has the advantage over other ECU tuners as it actually reads what's inside your ECU before tuning.  This ensures the correct tune is being loaded, making it a very safe device.  The AA custom tunes deliver the most possible power gains.  With our expert knowledge of Bosch throttle by wire ECU tuning, we are able to get around factory limiters, make a more responsive machine, and of course create more horsepower and torque.  Our tunes are loaded on the Powervision just for your machine, so all you do is open the box and download them into your ECU.  We recommend clutching with a tune to get the most out of your vehicle.  See below for even more features of our custom tunes. Huge horsepower & speed gains!  
• For the 2017-22 RZR 570, Polaris switched from a cable throttle to throttle by wire which gives Polaris an easier way to limit your horsepower and how that power comes on.  We change all of that to really bring the 570 motor to life and give its full potential.
• See 5-6 peak horsepower gains
• MUCH quicker throttle response and power delivery
• Throttle by wire limiters disabled
• AA's wicked timing curve built for 91-93 octane fuel
• A great fuel curve that gives much better low end (as well as all around) power as the factory map is very lean in key areas.
• Fan on/off temp lowered to 190/185 degrees Fahrenheit (factory is 198/192)
• Seatbelt limiter disabled
• Speed limiter removed in low and high gears (factory limits are 52mph in high, 32 in low)
• 2 Foot limiters are disabled
• Rev limit at a safe 8000 RPM (factory rev limit is 7500)
• Very easy to use tuner that can also check and erase most trouble codes
• Easily data log 25 parameters with 1 push of a button and review on your windows computer later
• No mess of having to send in your ECU, and a safer way of programming your ECU

  • Level 1: This tune is a huge increase and can be ran with the stock exhaust.  This is seriously worth every penny!  You are looking at a 5-6hp peak gain with the tune, and the down low grunt is absolutely awesome.  Peak power is 7500-7700 @ 45mph.
  • Level 2: This tune has all the same benefits as level 1, with increased fueling for and a slip-on or full exhaust system. Together with a tune and exhaust you can see 8-10 horsepower gains!
  • Level 4: This tune has all the same benefits as Level 2 but with increased fueling and timing for a big bore kit.
• Valet/Kid mode tune is available ONLY FOR 2017 OR NEWER MODELS with throttle by wire. It is perfect if you have a younger one you don't want to have full power.  This tune offers a 35mph speed limit, and only 50% throttle for the 570 model.  These two factors can be customized, just let us know if you would like them set differently in the comments section when checking out online.
• Wondering why go with our tune(s) over the DynoJet tunes? We go the extra mile to make sure everything is gained, and have a few extra tricks up our sleeve because we test in the real world. Other maps take their time to hit peak timing numbers which really hurts performance. Our map gets you into peak timing quicker, so max power seems more instant. We also have a great fuel curve that is designed to go with our timing curve, and offers better fueling for more power at WOT.  We also do some work with torque limiters as in the dirt we saw throttle closures when spinning the tires. Our map fixes that issue giving you 100% locked power delivery.  We also do the easy things like up the speed limiter to where you will never hit, disable 2 foot limiters, and disable seatbelt limiters.
• Looking for a custom race fuel tune? We also have those available upon request. They offer a timing curve set up for race fuel. Please e-mail if you are looking for race fuel tunes.
• To help better transfer the power gained to the wheels and to achieve proper peak RPM, the Lock & Load Kit includes our S1 clutch kit!  With the RZR 570, you normally hit peak around 7200 RPM with the tune and factory clutching.  To gain more power, we get those RPM up with our clutch kit at 7500-7700 RPM.
• Clutch kit benefits:
  • Adjustable allowing for higher RPM & more power
  • Adjustable for larger tires or paddles
  • Faster acceleration
  • Wicked throttle response and quicker down shifts
  • Cooler running belt temps (especially when running larger tires or paddles!)
• A setup guideline is included which shows the best setups for dunes, mud, or all around trail riding. This also has brief instructions on installing your clutch kit, and other important information.
• If you have any other needs or concerns for the tunes and/or clutching; please e-mail!
