Aftermarket Assassins S4 Clutch Kit with Heavy Duty Primary & Secondary | 2022+ RZR Turbo R
From trail rigs to high horsepower, this is the only clutch we will run on our shop vehicles Works on stock vehicles all the way to our 330 crank HP big turbo setup This kit includes our complete heavy-duty AA primary clutch. This clutch is the same design found on the 2016-2020 RZR Turbo models with an encapsulated tower design. We found this clutch to hold power better, hold up better (no exploding), and slip the beltless. It simply meets the demands of these high-horsepower vehicles and is proven.
This clutch also holds a belt grip better than billet clutches, especially when clutching for higher RPM. This primary clutch is our own version made with higher-grade tool steel for the post, assembled with AA HD sliders, to our AA specifications. With this clutch, you'll notice better power transfer (better acceleration) and lower belt temps than your OEM P90X clutch or any other aftermarket clutch Kit Includes: AA Primary Clutch, Primary Bolt, AA magnetic adjustable clutch weights, weight setup sheet, AA primary spring, custom Primary Limiter, replacement factory secondary clutch, AA Helix, AA secondary spring, and now includes AA Extreme Heavy Duty primary sliders (comes installed in clutch). The clutch does not come assembled. Simply set up your weights according to our setup chart, then install the weights & Spring.
Otherwise, we have the +$25 option to have us assemble the primary clutch for you, as long as you let us know what engine modifications and tire size/type. Great article to read about your P90X Clutches and common issues: https://aftermarketassassins.com/tech-blog/f/2020-rzr-pro-xp-clutch-issues#
Our S4 Recoil Clutch Kits (S3 kit with replacement secondary) packs 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 many hours into testing different setups in the real world. We know you'll be extremely pleased with the performance gained from our clutch kits! The biggest problem with Turbo R clutching is they do not have enough belt grip.
Our S2 kits help combat this with a stiffer secondary spring yet for even better belt grip, and the right primary weight/spring to get proper RPM. Our S3 clutch kit includes everything the S2 does but adds the helix. The helix adds a more aggressive shift to the secondary clutch which gives you great acceleration gains and feels more like your throttle is locked to the rear wheels. Kits work great with both stock or modified machines Works well with tire sizes 32" to 35" and paddles 30" to 33" A must-have when tuning your Turbo R to properly transfer the power to the wheels and prevent even more belt slip A must-have when running larger tires or paddles Wicked throttle response when on & off the throttle More efficient power transferred to the wheels More consistent clutch performance Cooler running belt temps (especially when running larger tires or paddles!) Longer belt and clutch life are Easily adjustable if needed Slightly higher engagement which is still very smooth (around 1800-2000 RPM) 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 modifications in the future, all 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 the best performance for your application. An initial setup guideline (normally very accurate) 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. Helix features a tighter roller & EBS pocket for less clutch slop (clunk) and less chance of rollers breaking High Load Helix 1062: 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 Turbo R 2 & 4 seat models with 32-35" tires or 30-33" paddles. Excellent all-around helix for any Pro XP or Turbo R! Performance Helix 1065: Aggressive helix with acceleration/higher horsepower/aggressive fast-pace drivers in mind. Works best with a tuned vehicle. Works on Turbo R 2 seat models with 32-33" Tires. Not suggested for Turbo R 4 seat models.
View our installation video HERE DISCLAIMER/SPECIAL NOTES ABOUT THIS CLUTCH: This clutch is louder at idle as these clutches have a loose spider/slider tolerance until engine RPM ramps up. This clutch is tight under the cover and MAY slightly contact the plastic at idle, making a few wear marks (extremely uncommon, but we have seen it due to cover variances). The primary bolt has a turned-down (shortened) head to clear under the cover. This is easier to strip, so use care when tightening, and make sure you use an 18mm 6-point socket. If dissembling the clutch, the 6 spring cover button head Allen bolts are also easy to strip if you use the wrong size (or standard), they are 4mm. Clutch Puller Note: You will need the P90X-specific clutch puller to remove your OEM clutch. The AA clutch coming in this kit uses the standard XPT/XP1000 primary clutch puller. Special tools needed Compression Tool #1, P90X Clutch Puller 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.
