Polaris RZR Pro R Stage 4 Clutch Kit with Heavy Duty Primary & Secondary

Our S4 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 biggest problem with Pro R clutching is they do not have enough belt grip. Our S4 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 helix adds more aggressive shift to the secondary clutch which gives you a great acceleration gains and feels more like your throttle is locked to the rear wheels.

This kit includes our complete heavy duty AA primary clutch. This clutch is the same design as OEM but with the option of either a full billet clutch or a billet inner sheave (known weak point) with cast outer assembly for lower cost. We found this clutch to hold power better, hold up better (no inner sheave exploding) and slip the belt less - especially when clutching for higher RPM and horsepower. It simply meets the demands of these high horsepower vehicles, and is proven.

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.

Naturally Aspirated Kit Choices:

Standard Load: The Standard Load clutch kit is meant for stock or near stock size tires and is the one for most fast pace riders or racers. If crawling with a 2 seat model on 34-35" tires, we recommend the High Load setup. You'll sacrifice some acceleration but have much better low end belt grip for less belt slip.2 Seat Models: 32-35" dirt tires or 30-32" paddles 4 Seat Models:  32-33" dirt tires or 28-30" paddles

High Load: The High Load clutch kit is meant for those with larger tires or riding style is mostly low speed crawling.2 Seat Models:  36"+ dirt tires or 33"+ paddles 4 Seat Models: 34"+ dirt tires or 32"+ paddles

Forced Induction Kit Choices:

Helix 1072: 1072 is the safe bet for any tire or paddle size, but especially larger tires like 35-37". If running 450+HP on 32-33" dirt tires, 1078 helix is required.2 Seat Models: 32-37" dirt tires or 30-35" paddles 4 Seat Models:  32-37" dirt tires or 30-35" paddles

Helix 1075: All out performance helix for those running 450+HP consistently.2 Seat Models: 32-37" dirt tires or 32-33" paddles 4 Seat Models:  32-35" dirt tires or light 32-33" paddles

Primary clutch does not come with the spring & weights installed. 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.

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.
