  • Fits ONLY 2020 RZR Pro XP Models 2 & 4 Seat  **DOES NOT fit 2021 Models as the helix design changed (coming December 2020)**
  • 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 belt less. It simply meets the demands of these high horsepower vehicles, and is proven.  This clutch also holds belt grip better than billet clutches, especially at higher RPM's.
  • Kit Includes: AA Primary Clutch, Primary Bolt, AA magnetic adjustable clutch weights, AA primary spring, weight setup sheet, custom primary spring limiter, AA secondary spring, & our AA custom cut helix
  • Primary clutch does not come assembled.  Simply setup 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. 
  • The biggest problem with Pro XP clutching is they do not have enough belt grip.  When the first Pro XP models arrived they had a soft secondary spring that slipped the belt under full shift.  They were then fitted with a stiffer secondary spring and now the problem is they rev too high for good belt grip with that spring. Our kit helps combat this with a stiffer secondary spring over factory 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 more aggressive shift to the secondary clutch which gives you big acceleration gains and feels more like your throttle is locked to the rear wheels.
  • Our S3 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 have many hours into testing different setups in the real world.  We know you'll be extremely pleased with the performance gain from our clutch kits!   
  • Kits work great with both stock or modified machines
  • Works with tire or paddle sizes 28" to 32"
  • 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 with larger tires or paddles
  • Longer belt and clutch life
  • Easily adjustable if needed
  • Slightly higher engagement which is still very smooth (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 modification 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 best performance for your application.
  • An initial 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 video HERE 
  •  DISCLAIMER/SPECIAL NOTES ABOUT THIS CLUTCH:  Primary is tight under the cover and MAY slightly contact the plastic... Making a few wear marks. The primary bolt has a turned down (shortened) head to clear under the cover. This is easier to strip, so use care when tightening. 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 a 4mm.   
  • We HIGHLY suggest running our Stryker Belt as we've found it grips much better in the clutch
  • Clutch Puller Note:  You will need the P90X clutch puller to remove your OEM clutch.  The AA clutch uses the standard XPT/XP1000 primary clutch puller. 
  • Special tools needed Compression Tool #1,  P90X Clutch Puller

    Growing up with robots...
    I'll spare you the obvious and only mention in passing that this is obviously a Roomba-wannabee. That aside, it turns out to be a pretty good R-wbee. Which is unsurprising since I combed through a couple of different comparison YouTube videos, both of which ranked this model near the top of their lists in the category of powerful vacuum robot on a budget. This lil sucker is indeed quite effective. I only have a carpeted bedroom, so it doesn't wander much, but it easily traverses even the bulged or steeped edges of my old burber carpeting. Like any such device, if you're going to leave it unattended, you will need to clear away any cords or other small debris (anything up to about popcorn size will just get vacuumed). I empty mine every other time I use it, and it's rarely brimming over. The only problems I've encountered have always been some kind of cordage or wire or string getting wrapped around the spinning scrubber unit--easily corrected. I'm very happy with the remote. I tend to use it mostly as a remote controlled vacuum device; ie, me lazily stalking behind it, using the remote to reverse it or to bring it back round for a second pass, til I'm satisfied. In addition to allowing N-S-E-W directions, you can also press and hold a direction button to make it speed up. You can also toggle between carpet and hardwood mode. The device charges pretty quickly and usually lets me get 2 to 3 large room sessions completed before displaying low battery. I will note that my kitten was a mere 3 months old when I got this device and she has literally grown up with it. It long ago stopped frightening her and now she regards this device as a friend and playmate to such an extent that I had to move the charging dock from a floor corner to a low dresser drawer--because when I left it out in the open, my cat would always manage to depress the big GO button and send it off partially charged, destined to tangle up my charging cables and neckties. So if you plan on letting your cat grow up with this robot, take precautions. I would definitely buy another one of these, and probably will. Recommended.

    Jury is still out
    Size: eufy L60 SES (renewed), Size: eufy L60 SES (renewed)
    I really didn't want to purchase another Eufy product. I'm very mad at them because they're security doorbell cameras failing so readily (like a hardwired doorbell that stops working and gives me the input that there's no batteries even after we had it rewired.) And I caution everyone I am not a fan of their customer service anymore. Years ago it used to be fantastic. It is rare today, when you send in a request for help that anyone fully reads what your expressing. You get scripted answers or links to technical information that you've already told them in previous communications you've tried. Anyway... We have a dumber, earlier version of the Eufy vacuum cleaner that is about 5 years old --recently replaced the battery because I really love how well it draws up dirt and hair... Though the little chamber constantly gets jam-packed and the machine always gets stuck. I decided to move that one upstairs and get a smarter vac (only) and looked into several that could manage pet hair and that had good mapping and the ability to avoid scooping up toys etc. What I like is the software's easy (much friendlier than Narwal!). I think the mapping was perfect right out of the gate. Ease of splitting out larger areas into rooms is just wonderful. The on-screen guidance as you're using this software is mostly excellent. I really like how you can choose a setting that the vacuum will go to recharge and re-start itself back into motion to finish the job that wasn't finished when it went kaput. I like that you can choose the frequency of having the vacuum empty into the charging station. These two features that I just mentioned are a little bit hidden under settings. I think tabs would be nice for some pictures like this. I don't like that it only has one rotating brush. The older Eufy has two and I think it's a much better design to sweep things into the suction range. I like the quiet of this vacuum. The older version was quiet and this one is quieter yet. As a matter of fact it worries me because the difference in suction sound makes it seem as though it really isn't changing at all. I am not so sure the suction is as effective as It's been bragged about in its right up and in other reviews... it's actually gone over places on my carpet and it really didn't pull up all the fur. (That is in the video) I have also watched it go over small pieces of cardboard from a scratching post and it didn't pick it up... Again if the brush was there on that side it would have been pushed into the suction path better. I am not a fan of how it seems to not know how to avoid things. When setting up and getting ready to map your home with the LIDAR, the guidance is to take everything off the floor that is possible. Of course I put things back down like the tall cat toy that that has absolute presence, no different than a small cat --and the vacuum just runs right into it and starts pushing it...Our cat food bowls and water bowls just get pushed around. And the vacuum simply runs right into any toy and doesn't bother going around any of it so I would be sure you DO NOT BUY THIS IF YOU HAVE A CAT OR DOG THAT LEAVES MESSES ON THE FLOOR! Also on some things that were not picked up like the kitchen table, I don't get how come this vacuum just runs into it with full speed. Also it is very weird that it has a real problem transitioning to rugs. I have a leather throw rug that stays in place with people and animals going across it. But this machine's able to nose it up into the air and then get tangled in it. It means that when I have my schedule in place I have to roll up this carpet and my toilet carpets. As you can guess it's annoying. I also found it odd that when I'm trying to have it avoid going over something I will stand in place and despite the fact that it is vacuuming according to a grid it actually came back and circled and bumped into my feet five times before it finally gave up. What if that was an animal that was standing there? Would it bump into it also? There are reviews on here that are so much more detailed. All I can say is I tried a Roomba (returned it to store) and I tried the Narwal (The mapping was awful and I returned that one also.) I'm simply not wanting to return another vacuum. I do want to note that I purchased this one and accidentally ordered a 'used' model which means somebody else returned it. I have a feeling it has to do with this weird occasional click click click sound that makes it sound as though something is stuck in the rollers or something to that effect. Now that I finished muddling through this review I do know that this week I'll be getting in touch with Eufy. I can't help but wonder is this really the way this thing is supposed to be working. Oh, I did get the setup with the vacuum bag tower. As others have said it is extremely loud. The feature that reportedly cuts cat hair also has some volume to it, but for all its noise I don't think it really cuts but maybe 50% of the hair. I still have to manually clean the roll brush frequently. See photo.

    Better than my new fancy robo
    Great suction power. Doesn't get stuck often. I've had this vacuum for 5 years and it still works great. We got an AirRobo with a mop feature and demoted the Eufy to the basement. But, the eufy works way better and I frequently bring it upstairs to pre-clean before the AirRobo. Love this vacuum! Do you have a version with a mop?

    The best little helper!
    Size: eufy L60 SES (renewed)
    I've never owned a robot vacuum prior to this, and was somewhat curious on how it would work, and what it would really do in my small home. I got the L60 refurbished unit, and it came in a brand new box and it looked brand new when I removed it from the packaging. I charged it up, setup the app and connected it to Wi-Fi, ran a cycle and it was all so easy. It mapped my home and it is was off! It does an absolutely fantastic job. I run it daily and can notice just how much cleaner my hardwood floors are. We have a cat who is intrigued by it, but it does a fantastic job of cleaning up the litter that is tracked from his litter box. That alone is a lifesaver. I will run it in the morning and at night in cats area to keep the hair and litter completely cleaned up. So far I've only had a few small issues where it got stuck, twice from items left out, and once from a dirty sensor. You really need to make sure you have things put away and have the areas picked up, especially of cat toys and shoe laces, and once in a while wipe the sensors off if they get really dusty. I highly recommend this, it truly has been a huge help just in daily pickup and keeping the house clean. Its absolutely worth the money.

    Changed my life!!!
    Size: C20
    Detailed review below if you want to read it. If you just want a quick summary: It changed my life, it’s worth every penny, just buy it! I don’t normally spend this much money on anything but, for me, it has been 💯 worth it! It does take some time to get it set up and get the settings that work for your needs and house but is worth it a thousand times over. Handles a massive amount of dog hair like a pro. Does good on all surfaces except cheap bath mats, you’ll have to pick those up. There is maintenance but it is not difficult or time consuming. App works well and issues are easily to troubleshoot. Anytime maintenance needs to be done, the app sent you a message and a video on how to do it. Detailed review: I’ve had this vacuum/mop for 6 weeks. I don’t normally do reviews but I’ve been telling everyone I know how this bad boy changed my life! Important to note I’m also cheap as H@ll! I don’t have much to compare it to in terms of how it measures up to the competition. I have a 10 year old first generation Eufy vacuum named BB8 that will fall down the stairs and suck up the dogs tail if not supervised so that’s my baseline. I have two 80lb Labs, two feral kids, a blue collar husband and OCD (like the kind you take medication for and left unchecked does permanent psychological damage to children). We moved from an 800 sqft house to a 3,000sqft house and by the time I was done cleaning the floors at one end of the house my family had already destroyed the other end. Keeping the floors clean and dealing with the dog hair tumble weeds was a full time job. My family had to be punking me with hidden bags of dirt and dog hair or something. I was losing my mind, literally! I spent the last 20 years saving for my dream house and the floors looked like a trap house no matter what I did! I thought our floors at our old house were bad because we had so many people in a small space. Turns out my family is just gross. In terms of this robot, who my kids have loving named Consuela, after the house keeper from Family Guy. (It is important to name them, they work better when they have names😅.) You don’t have to worry about her becoming self aware and taking you prisoner Terminator style as she is not super smart. She doesn’t always know what she is doing but she works hard at it! The first week of training was a little rough but now that Consuela and I have a system it’s a complete game changer. Comes right out of the box and set up is a breeze. I had a little trouble with the app because I already had Eufy everywhere in my house. I downloaded the Eufy cleaning app which made my Eufy home security app stop working. Eventually, I got everything on the same app and it works seamlessly (this was probably my own fault as I didn’t read the instructions bc I like to do things the hard way). Out of the box she has to map out your house. I found this was the most important step. The first time I had her map my house I didn’t move or pick up anything. The map sucked and it was a disaster. I redid the mapping step and literally picked up everything not nailed down, chairs small end tables, trash can, pots, etc. and kept the dogs downstairs. After I did this the map was absolutely perfect (a good base map is key). You don’t have to move everything when she cleans, just the first time to get a good map. My main level is one massive open concept (probably 1,000sft and Consuela identified it as one room), then 2 bathrooms and three other bed rooms. At first I tried telling her to clean the entire main level as it is one of the options. That did not go well. I feel like she might have a little adhd. I ended up taking the time to set up “Zone cleaning” scenarios and saved them on the app. Zone cleaning is the way to go with big open areas. I broke the great room into 3 sections. We have Apple home we linked to it so now we just say, “Siri, tell Consuela to clean the kitchen, living room, bathrooms, etc.” We played with the cleaning setting and found what worked for us. I have her programmed to clean different zones at different times a day. With my feral family we have to run max vacuum suction and two passes with heavy mopping so the battery drains fast. If your children were not born in a barn yard, you don’t run a wood shop and mowing business out of your garage and don’t have dogs who shed 12 lbs of hair per hour the normal settings would be fine and she could probably do our main level on one charge. With our workload she does two zones, takes a break to charge and then does two more. I have her programmed to clean each zone twice a day. I think for a normal family once every other day would be fine. My floors have never been so clean. NO dog hair anywhere! I’ve never lived in a house without dog hair. I did a deep cleaning of the floors throughout my house the day I got her and I have not had to vac or mopped since! I also think starting with clean floors is a key to success. This does not deep clean but if your start clean and run it often the floor stay spotless. With her running everyday nothing builds up in the corners, under beds and couches. It’s life changing (for me anyway)! We have laminate floors, carpet, tile and a few very thin rugs. She is amazing on the tile, carpet, and laminate but does struggle with the rugs. My rugs are super cheap, thin, and lightweight. She has lots of trouble with the bathroom rugs so we started hanging the bathroom mats after we shower which is actually better for us. Our large area rug is a bit of a struggle and hard to watch 🤣 but if I don’t watch her, eventually she moves on and it is clean. She has only gotten stuck on the rug once. So cheap rugs are a challenge but going from hard floor to carpet works perfectly! I do think she would do well with high quality heavy rugs. Like I said I have OCD so I keep a tidy house without much clutter. She does a good job avoiding objects, if the dog is napping she can “see” it and doesn’t suck up a tail like our other robot vac. It does an okay job avoiding cords but if it hits a phone charger on the floor just right it will suck it up. (Only happened once) My son left a shirt on the floor and it did end up sucking it up but it was an easy fix. All and all it does a good job avoiding dog toys and things on the floor but if she hits something at just the right angle she does get stuck but you just have to pull it out and hit restart. Consuela not going to clean up an entire bowl of cereal, a can of spaghettiOs or big spills. She would probably destroy the entire room. However, if my dogs leave a trail of muddy footprints she does do a good job spot cleaning stuff like that. She will keep clean floors clean indefinitely. Maintenance: this is not a set it and forget it type of thing. There is maintenance that needs to be done regularly to keep her going but it is not hard. There is a tray that pops out that needs to be rinsed. If you don’t, it gets clogged and pauses the cleaning cycle. Even when this happens it’s an easy fix. It has a disposable bag for dust and dog hair. Ours fills up once a week, a normal family could probably get several weeks per bag. They are not terribly expensive but I do NOT replace the bags! I just dump them out into the trash can because I’m cheap. I’m still on my original bag. Water tanks: we mop at least twice per day with the high water setting and a full water tanks lasts two days. The mop pads are cheap. We bought several and I just wash them once per week and it takes two seconds to change them. I think they’re supposed to be disposable. The worst part, which is not the vacuums fault or a design flaw, just the nature of the beast. The dirty water tank! We can go on a tank of water for two days but if you leave dirty water in the tank for an extended period of time it reeks like rotten sewage🤢. It does NOT make your house smell at all. You can’t smell it until you open it. If you empty it every day it doesn’t smell but if you forget and go on vacation like we did it’s bad! I started putting a few drops of bleach in the dirty water tanks when I empty it and we have zero smell now (no idea if it’s okay so do at your own risk). The app is awesome. If there is an issue the app sends an alert and tells you what’s wrong. It also pops up a video telling exactly what to do to fix the issue. Yesterday it told me I needed to clean the sensors and showed me how to do it. I don’t like to spend money on things like this but I use it so much I almost wish I would have spent the money on the top of the line model. Although I don’t have any complaints with this one.
