Aftermarket Assassins ’17-’20 Polaris RZR XP Turbo Stage 1 Lock & Load Kit

• Fits 2017-2020 RZR XP Turbo & Turbo S Models
• DoesNOT fit 2021 models, please see the 2021 RZR Turbo & Turbo S product section if you have a 2021 as the clutch system is different
• Kit Includes: AA Tuned PV3 Tuner, S3 Clutch Kit (2017-20 XPT 64″or2018-20 Turbo S 72″), Snap Ring Delete Kit
• Lock & Load! This Stage 1 kit provide a big increase in horsepower and torque simplified into an easy package. Tuning and clutching on the XPT go together like high powered rifles and tannerite. Together they pack a huge punch for the ultimate power gains to the wheels. For tune levels 3 and up, we’d recommend a performance exhaust. Our billet diverter valve (or blow off valve/BOV) is also highly recommended. The factory diverter valve is made from plastic and known to leak/fail prematurely. Our billet valve with double o-ring seals ensures no boost leak.
• This package features AA’s performance tunes loaded directly on the Powervision ECU tuner! This versatile tuner allows our tunes to easily be uploaded to your factory ECU, switch between tunes, and even return to stock. The Powervision is also a great gauge showing boost, timing and more. You can leave the Powervision hooked up for gauges, or completely remove it after flashing your ECU. The Powervision also has excellent data logging capabilities if you download the software, and use your laptop. You can even view trouble codes and erase them on the fly. We are highly experienced in tuning these RZRs and that will show. Our tunes are simply set up correctly, and everyone with a Powervision should have these tunes! They are also easily labeled and will show rough horsepower claims with supporting mods such as exhaust and clutching. These tunes modify all the necessary maps to create big horsepower, while still maintaining a reliable and safe RZR. Each tune is built specifically for your Powervision allowing us to change the tire size or fan temp if needed.
• This package also features our S3 clutch kit. No matter the terrain, they hit hard and just keep pulling for days. On the trail or at the race you’ll notice wicked acceleration and instant clutch response when getting back into the throttle after hammering that corner. In the dunes you’ll see the same benefits, but also have much less bogging when climbing that big dune. The machine will hold RPM so you can get where you need to go, and get there faster! Going mudding? Our mud setup will help turn those tires through the thick and deep with much better RPM and wheel speed that’s key to climbing out of that hole. We have a huge amount of CVT knowledge, a great passion for the sport, and spent many hours testing different setups in the real world. We know you’ll be extremely pleased with the performance gain from our clutch kits!
• Massive horsepower gains bundled in to a simple package
• Quicker throttle response and power delivery
• All level tunes feature: Throttle by wire limiters disabled, No overboost code, Fan on/off temp lowered to 185 degrees Fahrenheit, Seatbelt limiter disabled, Speed limiter removed in low and high gears, Rev limit at a safe 9200 RPM, more throttle in low gear, better throttle response, and much more!
• ECU Type/O2 Color drop down choice: 2017-18 models ALL have the standard black lead. In 2019+ models blue o2 leads are wideband models and we must know this. These models are a different ECU type and will NOT do an ECU read (we supply your stock file). For more information on this, see this link:/tech-blog/f/rzr-turbo-evap-ca-models#
• 1 tune is included in the price. We would recommend going with 2 tunes, especially if you choose level 3 or higher.
• For reference; a 2017-Up 168 HP crank horsepower stock machine will dyno at 135-138 RWHP on our dyno
• All tunes level 3 and higher will need the waste gate rod shorter for maximum power. ClickHEREfor a link on how to easily adjust the waste gate.
  • Level 1: This tune is a modified stock power level tune, but has better boost maps to help keep you in the power. We disable many limiters, up the speed limit, rev limit, and make necessary fuel & timing changes. The 2017 factory tune runs a max of14.5-15 PSIof boost, and we keep that in this tune, it’s just easier to obtain & maintain that level.
    • No wastegate adjustment required.
  • Level 2: This tune offers16-16.5 PSIof boost and a10-12 RWHPgain. This tune can be used with the stock or aftermarket exhaust. Clutching is not needed but highly recommended with this tune, as just tuning the machine will not properly transfer the power to the ground. Clutching is another big horsepower gain. 91 Octane tune.
    • Suggest Mods: Aftermarket exhaust and clutching.
    • No wastegate adjustment required.
  • Level 3: This tune is a game changer! Hitting hard at+20-25 RWHP, this tune offers the highest boost possible (17-17.5 PSImax) on 91-93 octane fuel. Due to the thicker head gasket and larger injectors on the 2017+ models, we are able to get away with his kind of power on pump fuel. These are absolutely huge power gains that will have you grinning from ear to ear. 91 non ethanol/non oxygenated fuel or 93 octane is required. If fuel in your area is poor, we’d suggest using a half can of VP Madditive or Boostane to help fuel quality. 1/2 gallon of 110 or better race fuel would also work to boost octane levels.
    • Required Mods: Aftermarket exhaust and clutching.
    • Suggested Mods: Billet Diverter Valve (BOV)
    • Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
  • Level 4: This tune is designed for 98-100 octane (will run on UTV 96, or most fuels up to 110 octane) and was developed using one can of VP Octanium to a tank of fuel. Mixing other race fuel with the tune to get 100 octane output would work great, just keep in mind leaded fuels can take out O2 sensors when running leaded fuel consistently. This tune runs around17.5-18 PSImax. We correct many maps for this octane rating, ensuring the most possible power. This tune pack a huge punch with just a small amount more octane.
    • Required Mods: Aftermarket exhaust and clutching.
    • Suggested Mods: Billet Diverter Valve (BOV)
    • Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
  • Level 5: Get ready to drop the hammer! If you don’t like to lose races, this tune is your friend…. and If you’re friends don’t like to lose either… they might not be your friends for long. This tune is developed for 110 octane fuel (unleaded is recommended if you are keeping you plan on running your O2 sensor) and really hits hard. This tune runs around18.5-19 PSImax. From extensive testing, we know that this is the limit of the factory turbo before it becomes inefficient and simply starts blowing too much hot air so we went to our timing tables and did some work. Adding a revised timing curve with these boost pressures is a recipe for absolutely stupid power that hits harder than you can imagine.
    • Required Mods: Aftermarket exhaust and clutching.
    • Suggested Mods: Billet Diverter Valve (BOV)
    • Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
  • Level 6: Have E85 local to you? Time to fill up and start turning heads! This tune is developed on the stock injectorsandstock fuel pump for E85 fuel… that’s right, just gas up and hammer down. E85 is a great race fuel replacement as it runs very cool and can sustain high boost and advanced timing maps….. which equal awesome power! We crank out all that our Level 5 tune has to offer and even push it a little more. Keep in mind E85 takes about 30% more fuel to run, so it will guzzle fuel fast. This tune runs an average of18.5-19 PSIof boost.
    • Required Mods: Aftermarket exhaust and clutching.
    • Suggested Mods: Billet Diverter Valve (BOV)
    • Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
• Why our tunes over the DynoJet tunes? This really depends on our tune level. The great thing with our tunes is they are easily labeled, list boost numbers, and rough horsepower gains. They have been proven to make and hold power longer than the DynoJet tunes. Not only this, but we test with clutching, exhaust, and other parts to ensure our tunes work well with all factors. Lower level tunes (1-2) are actually much safer than a DynoJet “max boost” tune especially if running stock exhaust, yet deliver more power than their low boost tunes. Safer tunes will hold power longer, and be much easier on your motor. When your RZR de-tunes because boost is too high for the modifications or fuel, it can become slower than stock! Our Level 3 tune has higher boost, and comes on harder. Our Level 4 and up tunes are adding in race fuel and will offer even more power than any DynoJet tune. Since we have so much time on RZRs, we know the limits and can push the limiters further giving you higher speed limits, and many other things hidden in our maps. Everything is taken care of for you, ensuring you have the best tune(s) out there… that should be worth every penny!
• Please see helix options below:
  • Torsion Anti-Chatter Kit: Upgrades to a complete secondary converted to a Torsion style spring and helix. The main benefit is better belt grip with the Torsion spring that gains rate as it shifts. Constant pressure against the helix buttons for less annoying secondary clutch chatter which also extends the life of the buttons. You’ll also notice smoother engagement which is excellent for those crawling. Secondary bushing comes peened over to prevent walking out. The Torsion kit slightly limits top speed and should be used with the AA primary clutch limiter. 80-85 MPH top speed for most models.
  • Performance Helix 1031/Torsion 1026 (aggressive holeshot): This helix works excellent for the listed setups and has a more aggressive shift angle from 0-25mph over the 1024 performance helix. This is best for holeshots and aggressive riders that are trail riding, dune riding racing, and drag racing. This setup will still crawl good when needed, but if your riding is more slow speed/crawling, we’d suggest the 1024 helix or 1032 Torsion helix.
    • XPT 64″ 2 Seat: Works well with 28-32″ Dirt Tires, 28-32″ Dune Paddles
    • XPT 64″ 4 Seat: Not Recommended – See 1024 or 1021 Helix
    • Turbo S 72″ 2 Seat: Works well with 30-33″ Dirt Tires, 30-32″ Dune Paddles
    • Turbo S 72″ 4 Seat: Not Recommended – See 1024 or 1021 Helix
  • Performance Helix 1024:The only difference over the 1031 performance helix is the shift angle from 0-25 MPH is slightly less aggressive. This makes it better for crawling and those slow speed situations, but it still pulls like crazy when needing to accelerate hard. **Keep in mind if you have a 2018+ 4 seat model they are geared higher. If your tires or paddles are 31-32″ and heavy, you may want to go with the high load clutch kit**
    • XPT 64″ 2 Seat: Works well with 28-32″ Dirt Tires, 28-32″ Dune Paddles
    • XPT 64″ 4 Seat: Works well with 28-32″ Dirt Tires, 28-32″ Dune Paddles
    • Turbo S 72″ 2 Seat: Works well with 30-33″ Dirt Tires, 30-32″ Dune Paddles
    • Turbo S 72″ 4 Seat: Works well with 30-33″ Dirt Tires, 30-32″ Dune Paddles
  • High Load Helix 1021/Torsion 1032: If you are using very large/heavy tires, the high load helix might be the choice for you. The high load helix is recommended for those turning heavy 34-35″ tires. This angle slows the shift down to help act like it’s “gearing down” the secondary clutch. This helps not over shift and cause belt slip. **Keep in mind if you have a 2018+ 4 seat model they are geared higher. If your tires or paddles are 31-32″ and heavy, you may want to go with the high load clutch kit**
    • XPT 64″ 2 Seat: Works well with 34-35″ Dirt Tires, 32″+ Dune Paddles
    • XPT 64″ 4 Seat: Works well with 32-35″ Dirt Tires, 32″+ Dune Paddles
    • Turbo S 72″ 2 Seat: Works well with 34-35″ Dirt Tires, 32″+ Dune Paddles
    • Turbo S 72″ 4 Seat: Works well with 34-35″ Dirt Tires, 32″+ Dune Paddles
