• From trail rigs to high horsepower setups, this is the only clutch we will run on our shop vehicles
• 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 and now assembled with AA HD sliders to our AA specifications along with our Revolver Billet Clutch Cover with Tower Lock for even more strength and airflow.
• 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 w/AA Revolver Billet Clutch Cover with Tower Lock, Primary Bolt, AA magnetic adjustable clutch weights, AA primary spring, weight setup sheet, custom primary spring limiter, replacement secondary clutch with encapsulated bushing design, AA secondary spring, our AA custom cut helix, and includes AA Extreme Heavy Duty primary sliders and AA HD secondary rollers (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. 
• Our S4 Recoil Clutch Kits (S3 kit with a replacement secondary loaded with AA HD rollers) 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.   They will simply help primary clutching and get things dialed in to where they should be.
• Buttery smooth engagement, gets rid of the factory jerk off idle
• We especially recommend this with our tuning as it will allow for higher RPM which allows you to reach the peak power of the Ranger 1K motor
• A simply must have when running larger tires
• Faster acceleration
• Wicked throttle response and quicker down shifts
• Cooler running belt temps (especially when running larger tires)
• Longer belt and clutch life
• More consistent clutch performance
• Easily adjustable if needed
•  Helix features a tighter roller & EBS pocket for less clutch slop(clunk) and less chance of rollers breaking:
  • Performance Helix 1043:  Aggressive helix with acceleration/higher horsepower/aggressive fast pace drivers in mind.  Works best on Rangers with 27-30" tires and OEM gearing or those running 31-35" tires with gear reduction.  
  • High Load Helix 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 best on Rangers with 31-35" tires and OEM gearing. Excellent all around helix for any Ranger! 
• 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.
• Our great setup guideline lets you know how to set the weights up for different size tires and other variables, as well as how to check to make sure clutching is setup correctly.
• 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.   
• 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. 
• Have alignment issues? Use our P90X Secondary Clutch Alignment Shim Kit to set things straight
• Highly recommend installing a new belt at the same time, we have the World's Best Belt (Our Stryker)
