This clutch is the same design found on the 2016 2020 RZR Turbo models

  • Fits ONLY 2020 RZR Pro XP Models 2 & 4 Seat  **DOES NOT fit 2021+ Models as the helix design changed**
  • Kits are build to order with a 1-3 day lead time
  • From trail rigs to high horsepower setups, 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 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.  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, AA primary spring, weight setup sheet, custom primary spring limiter, replacement factory secondary clutch, AA secondary spring, our AA custom cut helix, and now includes AA Extreme Heavy Duty primary sliders (comes installed in clutch).
  • 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. 
  • Great article to read about your P90X Clutches and common issues:  https://aftermarketassassins.com/tech-blog/f/2020-rzr-pro-xp-clutch-issues#
  • 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 S4 Recoil Clutch Kits (S3 kit with a replacement secondary) 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.  
  • Performance Helix 107-1043:    Aggressive helix with acceleration/higher horsepower/aggressive fast pace drivers in mind.  Works on Pro XP 2 seat 30-33" Dirt Tires, 30-32" dune paddles.  Works on Pro XP 4 seat with 30-32" dirt tires, 28-30" dune paddles.  
  • High Load Helix 107-1042:    Slightly less aggressive than the 1043 helix with good acceleration gains/power transfer over the OEM helix.  Designed for a heavier vehicle, heavier tires, heavy sand load or crawling type riding in mind.  Works on Pro XP 2 seat 30-35" Dirt Tires, 30-32" dune paddles.  Works on Pro XP 4 seat with 30-33" dirt tires, 28-32" dune paddles.   Excellent all around helix for any Pro XP!

  •  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 a 4mm.   
  • 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.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol
