MCB 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 success of these exceeded our expectations with thousands sold. Taking the proven design to the next step with BP series design.
The original Pro-series design features the following design features.
- 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 considerably more miles 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 failure. The MCB Pro-series uses a threaded collar that incorporates 1-1/4" of overall thread engagement, that's a 400% increase.
- Now in addition to all the above listed features. The new Pro-series BP clutch will incorporate rectangular spider pucks that are 26.5mmx20mm 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. 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.

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 26.5mmx20mm 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.

Four stroke head exchange. MCB now offers fully assembled remanufactured four stroke heads for most common SxS, ATV and MX. Just like our cylinder and crankshaft exchange program we are offering that same service with heads for DIY builders. Heads are so often overlooked, they really are approximately half of a four stroke engine assembly. Burning oil? Most customers always assume oil consumption is a result of worn piston rings. In most MX, ATV and SxS applications that is not the case. A worn head with worn valve guides allows the valve stem to wonder, working and compromising the valve seals and therefore resulting oil consumption. Installing new valve seals will not make the valve stem not wonder, and end up with the same result: Oil consumption.

MCB PREMIUM Re-manufactured, COMPLETELY assembled cylinder heads. All heads are OEM. Heads are hot tanked, bead blasted, Exhaust guides upgraded to Bronze (Intake if needed), Newen Contour Valve job, ALL NEW Alloy HD Valves, All new Viton hat seals (or Minimum if required ,If needed deck is machined (min.), and Head is assembled and vac. tested. Prices and timing vary depending on several factors.

Two and Four Stroke cylinder repair! MCB has long been known for large inventory of remanufactured cylinders for immediate exchange. Many customers do not know the extent of what can be repaired. We now have the technology to weld detonation erosion, broken skirts, base damage! Using CNC programming these cylinders can be welded and machined back to exact dimensions!! Do not scrap them severely damaged cylinders anymore!!
