MCB Performance releases it's Polaris RZR 1000 Pro-series "BP" (big puck) clutch.
Two years ago we released our STD Pro-series Polaris RZR 800/900/1000 clutches. The reliability and success of these clutches exceeded our expectations with thousands sold across the USA and Canada. Taking the proven design to the next step with "BP" series design.
The original Pro-series design features the following design enhancements.

- Main post is 38mm vs stock 28mm, resulting in the faceplate bushing surface area to be increased by 44%. This results in a more stable moveable clutch half. Reducing clutch binding, scrubbing, friction, heat and noise by keeping the entire moveable half true to the fixed half for considerable more miles/hours before unsustainable wear occurs.

- In addition, the stronger open design Billet faceplate keeps the moveable sheave spider towers from flexing at the six bolt locations and causing premature spider puck wear by preventing tower deflection under high load.

- MCB Pro-series clutches use a splined spider vs threaded. High HP applications have proven to strip the aluminum spider threads, this cannot happen with the MCB Pro-series.

- MCB Pro series clutches do not use a spider jam nut. As many RZR owners know the stock spider jam nut only allows for 1/4" of thread engagement. Many have experienced the jam nuts coming lose and allowing the spider to move resulting in catastrophic failure. The MCB Pro-series uses a threaded collar that incorporates 1-1/4" of overall thread / loctite engagement. That's 400% more thread engagement.

- Now in addition to all the above listed features. The new Pro-series "BP" clutch will incorporate rectangular spider pucks that are are 25.5mmx20mm vs 16.0mm diameter standard puck. Resulting in 150% increase in surface area. Why is this needed? All HP and Torque that your given RZR makes is transferred to the moveable sheave in order to close in on the belt via the spider pucks! The fixed sheave just goes along for the ride. The moveable sheave does all the work clamping the belt for upshift / acceleration. Dispersing this load over a puck that is 150% larger prolongs puck wear, moveable sheave tower wear and deflection. Resulting in an overall smoother, longer lasting clutch that provides a more efficient transfer of horsepower to the ground.

- All MCB Pro-series come with a 1 year limited warranty and they are individually calibrated for your tire size, modification, riding style, and elevation.

Comes fully calibrated ready to mount. Custom if you have oversize tires by choosing the appropriate box / tire size. We can also custom tune your clutch for specific applications. Rock crawling where high speed is not a need. Deep mud only where all you want is lots of low end torque. High speed trail of seasonal road running where you'll be in the mid to higher RPM's most the time. We can custom tune for your needs. In all cases the clutch comes with some adjustability by adding or subtracting weights. This is easily done with no special tools. You do not even need to remove the primary spring, or even take the clutch off the machine for that matter. Additional weights and spring rates are available for those need wide variation in adjustability.
