MCB Polaris RZR 800 primary drive clutch FOR ALL 2008-2014 models.
- Uses the same belt as your original clutch
- No secondary clutch changes needed
- Uses the same puller as your original clutch

If you are uncertain of your clutching issues and think you might also need a secondary clutch please look at our clutch combination kits that include both a Primary and a Secondary clutch.

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. Our MCB pro series accepts the same spring and weights as a stock Polaris clutch. Additional weights and spring rates are available for those need wide variation in adjustability.

This clutch is our own design. It is a replica of the OEM Polaris primary except our clutch uses superior bushing material. Our open style billet faceplate allows for better cooling, more stable moveable sheave towers, prolonging spider puck wear. The faceplate bushing incorporates more surface area (diameter and height)and is a self lubricating brass oil impregnated material. Our spider is splined instead of threaded on like a Polaris clutch. This eliminates the spider and jamb nut from being able to unthread them self like so many owners experience. Our clutch has no spider nut. Instead it has a thread collar that makes the main post larger for the larger bushing as mentioned above. This also allows for a full 1.5" of thread and loctite engagement further eliminating the spider nut or in our case "post collar" from unthreading. Our weights are "bushed" unlike the factory and other aftermarket clutches that use steel on steel weights and pins. We use only the highest quality alloy materials for the sheaves and nitride coated tool steel on the main shaft and crankshaft mounting countersink area. The clutch is precision balanced. Our spider pucks are 100% PHENOLIC!

We calibrate each clutch that leaves here for 2-seater vs 4-seater, Tire size, elevation, and riding preferences, etc. (see prompts at checkout)

Uses the same puller as your original clutch
