  • Fits 2022-Up RZR Pro R 4 Cylinder Models 2 and 4 seat 
  • 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!   
  • The Pro-R comes with the biggest CVT clutch ever fitted on a UTV so far. It has unmatched cooling/airflow to keep the longer belt cool, and some great features. However, this large diameter P90X clutch system still has some flaws.  The biggest problem with Pro R clutching is they do not have enough belt grip.  Just like the Pro XP/Pro R/RZR Turbo models, the secondary spring is too soft from the factory, but just adding a stiffer spring is not the correct solution.  It's the combination of parts that adds correct belt grip.  Our S3 kits help combat this with a custom AA helix and stiffer secondary spring yet for even better belt grip, and the right primary weight/spring to get proper RPM and keep belt grip up in the primary clutch.  We go from seeing a ton of black belt marks on the secondary, to almost nothing during long wide open throttle abuse testing.
  • Our Clutch kit on the Pro-R ramp up RPM faster for better acceleration out of the 4 cylinder motor, making them accelerate much faster and quicker response.  After many tests to hold consistency/RPM run to run, we gained nearly 7rwhp of ramp up power at roughly 40mph over the OEM helix/S2 clutch kit!  This shows us what we felt when driving, the OEM helix is not transferring the torque of the big 4 cylinder.
  • 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 even better acceleration gains and makes you feel more locked to the rear wheels.  This is extremely important on the Pro R as they seem to rev quite a bit down low, without the feel that the RPM is getting to the tire.  We spent many hours in the field and on the dyno testing different angles to find what works absolutely best.  We found this angle works great with all tire sizes and a high load specific angle was not needed due to the low range gearing and larger clutches.  Simple weight adjustment settings will get you dialed in on 32-37" tires.
  • The AA helix has MUCH less roller/ratcheting noise when going from load to unload on the driveline.  Our role pocket is smaller and without the EBS notch (don't worry they still have great engine braking, especially in low).  This also helps extend secondary clutch roller life.
  • Kits work great with both stock or modified machines
  • Works well with tire sizes 32" to 37" and paddles 30" to 33".
  • If running larger tires than listed or gear reduction, please let us know before ordering.
  • A must-have when tuning your Pro-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/vehicle performance
  • Cooler running belt temps (especially when running larger tires or paddles!)
  • Longer belt and clutch life.  This kit allowed us to run on 1 belt in a 350 mile wide open/high speed Iceman race and had more life left.  Others with OEM clutch or other kits had belt issues.
  • Easily adjustable if needed
  • Very smooth engagement (around 1800-2000 RPM).  If looking for higher engagement let us know, we have other spring options.  
  • 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 most common tire or paddle sizes. This also has brief instructions on installing your clutch kit, and other important information.  
  • Installation video see HERE
  • Kits include: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, custom helix, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
  • We highly recommend our Primary Clutch Limiter which fixes the over-shift issue that causes the belt to hit the inner clutch cover and greatly decreases the chance of belt slip along with many other clutch issues
  • We highly suggest our Revolver Billet Clutch Cover with Tower Lock to strengthen the clutch and provide more airflow for even better cooling
  • The only special tool needed is our Compression Tool #1

Read this review. This pillow saved me.
Size: Standard/Queen (Pack of 1), Style: High Loft (6"-7")
I have to testify about this pillow, my brothers and sisters. Ever since I hit my 30s, my body has gone down. Aches and pains. Pops. Crackles. Snaps. It’s ridiculous. Over the last 2 years, I have managed to injure a muscle in my shoulder and the pain is unbearable when it is inflamed. I finally narrowed it down to the pillow I was sleeping on. I have an attachment to a pillow I’ve owned for over 20 years - that’s another story. I could fold it 3 times and it was finally thick enough to support my head. My shoulder got so tore up recently that I had to go through 2 rounds of steroids plus round the clock ibuprofen. Waking up in the night, the whole ordeal. I ordered this pillow after much research all over the internet. I was appalled by the $165 price ticket. But when you’re in that level of pain, you’re just about willing to do whatever it takes. The first night I immediately noticed I got more consecutive hours of sleep than I had in weeks. A week later and my shoulder is pain free. I could’ve cried. The height of this pillow stabilizes my neck and shoulders perfectly. It is firm, but gives and contours to your neck and head. It’s a heavy pillow but I don’t even care. Truly I don’t think I’ll ever go back. This pillow has saved my shoulder and I’ll never stop thanking God for it. If you’re experiencing back, shoulder, or neck pain and are considering this pillow, just order it. Please. Just do it. I’m forever changed. But I’m still keeping 20 year old pillow… just for sentimental purposes. 😂

Really good pillows
Number of Items: 1, Number of Items: 1
I’ve been using this pillow for a while now and it’s honestly one of the most comfortable pillows I’ve tried. It has a soft, cloud-like feel but still gives enough support for my neck and shoulders. I’m a side sleeper and it keeps its shape well through the night. The material feels high quality, and it doesn’t go flat like cheaper pillows. Definitely improved my sleep quality and worth the purchase.

Soft AND supportive
Number of Items: 1
I knew I needed a very soft pillow - all the foam pillows I had bought recently to try to upgrade our home pilllow selection seemed ok to the touch but were still too firm once I tried them out, but recently I also had some neck pain that needed some gentle support and the old old foam pillow I had that was so very soft was losing its supportive qualities and the pain wasn’t getting better. This one seemed by description to fit the bill- very soft by the company’s own definition but also with support. I’m happy to report this is exactly as advertised- the softest foam pillow I’ve tried out of the box but also good support. Pain has improved since I started using this pillow. I would buy more if we need more pillows, it’s perfect for me and I think would be comfortable for most people. I think you just need to figure out how firm you need your pillow and also height preference . I’m an all over sleeper -back, side, even belly sometimes, so it’s fine for me, but it is a little taller compared to other pillows I’ve bought recently. I didn’t compare/try other prominent pillow brands, mostly my experience is Ikea (my daughter uses a very flat and nice foam pillow from them that is even a little pricier than this one and it works well for her), and whatever brands happen to be available at target and Costco. This price point for a name brand is reasonable, I think; I was looking at other brands way over $100, and I was willing to spend that much for something that would work long term, so this one working was great. Also, this definitely does not have any cooling effect technology, which is fine by me, but something to consider if you do like cool pillows. (Although, PSA: I recently had to throw away older foam pillows that had those cooling gel panels because the gel panels started disintegrating into sticky ooze; gross and had to throw away whole pillow because couldn’t dissociate from rest of the pillow. Sad cuz the foam part of those pillows were fine.) Anyway, if you like softer pillows but want good support, this one works well and is worth trying!!

Flatter than a regular pillow but nice and soft
Number of Items: 1
Is it softer than a typical memory foam pillow? Yes. But it’s also a lot flatter. I don’t find this pillow rebounds very well. It’s good for stomach sleepers but not so much for side sleepers. I’m a 2/3 of the night side sleeper so it’s unfortunately not my magic pillow.

Best pillow for my neck pain.
Number of Items: 1
I've tried so so many pillows to relieve my neck pain at night and this one is the first pillow that has actually worked. I was skeptical at first as this pillow is heavy and dense but one night and I was hooked. I couldn't believe I found a pillow that actually not only was comfortable but also relieved my neck strain. It's worth the cost to now be able to wake up without pain.
