Polaris RZR Clutches and Clutch Kits
Bolt 32" tires onto a stock RZR XP 1000 and climb a rutted hill at 6,500 feet, and the factory primary clutch will be scrambling to hit that RPM range the whole way up. The truth of the matter is, it’s a clutch built for sea-level trails and stock rubber, not the setup you're actually running. Swap in a re-weighted primary and a matched secondary spring, and the same climb turns into a much smoother pull with the belt staying cool instead of slipping. That's the whole job of an aftermarket clutch kit: rebalance engagement RPM and shift rate for the tire size, elevation, and riding style your RZR actually sees, using billet weights, aramid-fiber belts, and re-cut helixes instead of the one-size-fits-all setup Polaris ships from the factory.
Fitment is tied fairly consistently to drivetrain lines, but they aren't the only factor. The turbocharged models (RZR XP Turbo, Turbo S, Turbo R, and Turbo S4) run a different primary clutch and puller thread than the naturally aspirated 1000-class machines (XP 1000, Pro XP, Pro S, Pro R, RZR-S 1000, Trail, Trail S), and the older 900- and 570-class RZRs (900, 900 XC, RZR-S 900, RZR-S 800, 800) split off again. Within each drivetrain family, tire size and elevation band (0–3,000 ft., 3,001–6,000 ft., 6,001 ft.+) determine which weight and spring combination is correct: GBoost's XP 1000 kits alone come split across four different elevation-and-tire configurations for that reason. We carry SuperATV, GBoost, and Aftermarket Assassins across every one of those splits, and if you're not sure which combination matches your Turbo S or your Pro R, text us at (920) 644-5280 or call (920) 543-5376. We're fitment experts first, and we'll match the kit to your machine before you spend a dollar. With 25K+ products across 300+ brands before you even count clutch weight and spring variants, this is the deepest Polaris RZR clutching catalog online.

Buyer's Guide for Polaris RZR Clutches and Clutch Kits: Everything You Need to Know
Whether you're running Turbo S4 or XP 1000 power, the clutching system is the same basic architecture underneath: primary clutch, secondary clutch, belt, and cover, with weights and springs tuning how it all shifts.

What you give up |
|
Primary clutch kit (weights + springs) |
Rebalances engagement RPM and backshift for added tire weight or altitude — GBoost's XP 1000 kits are split by 33–35" vs. 36–40" tire bands |
Riders who've stepped up to 33"+ tires or ride consistently above 3,000 ft. |
Needs re-tuning again if tire size changes later |
|
Secondary/helix upgrade |
Re-cuts the helix angle to slow or quicken backshift, paired with a primary for full recalibration |
Hill climbers and mud riders who need lower gearing off the line |
Added cost stacked on top of a primary kit |
|
Clutch cover |
Bolt-on billet or reinforced replacement |
Anyone who's cracked a factory cover or wants better belt cooling |
Doesn't change clutch performance by itself |

Threaded tool for pulling the primary off the tapered crank |
DIYers doing their own clutch swaps or belt changes |
A one-time tool, not a performance part |

High-twist aramid or Kevlar-fiber belt built for the load a re-clutched machine puts through it |
Anyone running big tires or a tuned clutch setup |

What All Good Polaris RZR Clutches Have In Common
What separates a good clutch part from a cheap one shows up under load. A cast-aluminum factory clutch cover flexes and cracks. A factory rubber belt glazes and slips once you've added weight; GBoost's aramid- and Kevlar-fiber belts are built for the shock-load rating a re-clutched Turbo actually generates; that's a materials upgrade, not just a bigger number on the spec sheet. And on the primary side, magnetic adjustable weights (SuperATV's Warthog system, for one) let you fine-tune engagement without pulling the whole clutch apart every time you change tire size, where fixed factory weights mean starting over.
Let's Talk Polaris RZR Clutch and Accessory Pricing
Pricing runs in three real bands. On the low end, a clutch puller (EPI's Pro XP/Turbo S puller runs $51.99) or a bolt-on Quad Logic Turbo cover ($119.95–$134.95) gets you a maintenance-grade fix without touching the clutch's tuning. The sweet spot is a complete primary clutch kit: GBoost and SuperATV kits for the XP 1000 and Pro R run in the $346–$413 range and cover most riders who've added tires or ride at altitude, with adjustable weights built in. At the top, Aftermarket Assassins' Turbo S4 kit with heavy-duty primary and secondary and a billet Revolver cover included runs $1,695. This is the pick for high-horsepower Turbo builds that need the whole clutching system upgraded at once. The most common warranty is between 3–6 months, but Everything Polaris RZR does offer extended 1- and 2-year warranties on all products if that is something you are interested in. You can add the extended warranty right at checkout. Every kit here also ships with our risk-free 90-day return window and price-match guarantee, so a wrong-elevation weight swap doesn't have to be a wrong purchase.

Frequently Asked Questions
Q: I put bigger tires on my RZR and it feels sluggish. Do I actually need a clutch kit, or is something broken?
Nothing's necessarily broken. Bigger tires add rotating weight the factory clutch wasn't tuned for, so it holds a lower RPM and shifts later than it should. A re-weighted primary and matching secondary spring bring the RPM and shift point back to where the engine makes its power, without any other repair needed.
Q: What's actually different between a clutch kit for my Turbo model versus my XP 1000?
The Turbo models (XP Turbo, Turbo S, Turbo R, Turbo S4) run a different primary clutch, puller thread, and cover design than the naturally aspirated 1000-class machines, so kits aren't interchangeable between the two families. Within each family, the kit is further split by your tire size and typical riding elevation.
Q: Do I need a clutch puller to install a clutch kit?
Not always. Some kits install without pulling the primary off the crank. But if your kit calls for removing the primary, or you're doing a belt change, a puller like EPI's threaded tool makes it a five-minute job instead of a fight with a tapered crankshaft.
Q: How do I know which weight and spring setup is right for my elevation?
Manufacturers split kits into elevation bands. You’re typically looking at 0–3,000 ft., 3,001–6,000 ft., and 6,001 ft.+. This is because thinner air at altitude means less engine power, and the clutch needs lighter weights or a different spring rate to compensate. If you ride across more than one band regularly, tell us your typical range and tire size and we'll match the kit before you order.
Q: Are aftermarket clutch covers as good as OEM?
Many are better by spec, not just by the marketing hype. Quad Logic's billet Turbo covers use tower-lock bracing that resists both outward and lateral flex, something the stock cast-aluminum cover isn't built to do, with larger fins added for cooling. OEM covers are fine for stock machines; once you've added a clutch kit and more heat into the system, the reinforced aftermarket version is doing a job the factory part wasn't designed for.
