Aftermarket Assassins '16-'20 Polaris RZR XP Turbo S4 Recoil Clutch Kit

Aftermarket Assassins '16-'20 Polaris RZR XP Turbo S4 Recoil Clutch Kit

Complete clutches assembled with our AA performance clutch kit parts. This kit is normally for those who have clutches that are worn out. Let us know your exact model, modifications and tire size. We'll set your clutches up so they are ready to bolt on. Keep in mind vehicles vary so while they come set up, some minor weight adjustments might be necessary. Always verify your peak RPM after installation.

AA designed/tested/inspected high quality replacement clutches loaded with AA HD components

Our S4 recoil clutch kits pack a huge punch! 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!

S4 kits include our custom cut helix which will give you better power to the wheels on 2017-18 models because of the slightly steeper angle. All models will see a more consistent RPM sweep. Factory helixes start off steep, then go shallower on the top end. For turbo machines, this is completely backwards. We run a straight angle as changing the load on a heavy machine in the middle of a shift can cause some issues. Basically, 2016 helixes were too steep and therefor had belt issues, 2017 helixes went MUCH shallower and the performance to the wheels suffers. We found just the right angle to make everything happy with great belt life and great performance.

Our Recoil clutch weights are easily adjustable with simple magnets. They have a custom AA profile, the BEST coating on the market (nitrocarburizing) which has increased wear resistance, improved fatigue strength, and added surface lubricity. These clutch weights also offer great performance, and the ability to tune for many different applications or modification in the future, without the need to buy extra parts. The magnetic weights are the best option to properly place the mass where we need it on the weight for best performance for your application.

While this clutch comes pre set, 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. View our installation instruction video. Keep in mind all you will need to do is bolt the clutches on and not need to disassemble. Instructions show clutch disassembly.

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): For 2017-2020 2 seat XPT & Turbo S using 28-32" Tires / 28-32" paddles. Only helix we recommend for ALL 2016 models (due to lower gearing) unless running larger than 33" tires. This helix works excellent for the listed setups and has a more aggressive shift angle from 0-25 MPH 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.
• Performance Helix 1024: For 2017-2020 2 or 4 seat XPT & Turbo S 28-33" Tires/paddles. 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. A great all around helix choice.
• High Load Helix 1021/Torsion 1032: For 2017-2020 2 seat XPT/Turbo S 34-35" Tires. For 4 seat XPT 32-35" tires / 32" paddles. 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 32-35" 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 in those higher load situations. If you mostly use your RZR to crawl and/or have heavier 32-35" tires you may want to use this helix. If you have a heavy 4 seat and running 32" paddles, this would also be a good helix for you.
