Polaris Ranger 1000 with SOHC (single overhead cam) 2021-current MCB performance Primary drive clutch and Secondary driven clutch combination.

MCB Polaris Ranger 1000 w/SOHC primary drive clutch and secondary driven clutch combination FOR ALL 2021-current models.

Both clutches come fully calibrated ready to mount. Customized 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. 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.

Primary Clutch: This is our own MCB design. It is a replica of the OEM Polaris primary except our clutch uses superior bushing material. Our faceplate is an all billet design. Our main post is 38mm instead of stock 28mm diameter. This allows our faceplate bushing to have 64% more surface area. This significantly stabilizes the moveable sheave in staying parallel to the fix sheave. This results in less "clutch binding", reduces heat and results in an overall more durable and smoother shifting clutch. Our open style faceplate has more effective cooling. The billet design is stronger and doesn't deflect. This prolongs the spider puck life by not distorting the moveable sheave towers that the spider pucks push off of. Our spider pucks are 100% PHENOLIC. 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.

Secondary Clutch: This is a considerably better design than stock for both performance and durability. You stock 2021-current SOHC Ranger 1000 secondary uses a single set of rollers in a twin track small diameter helix. This makes the moveable sheave unstable based on the overall design and narrow stance of the single set rollers. This effectively creates "binding" resulting in poor upshift and backshift as well as excessive heat. This new clutch is a true tied roller clutch with 4 rollers, one set at both sides of the clutch creating maximum stability, no binding and significantly less heat. The rollers roll instead of slide and therefore wear is significantly reduced.

We calibrate each clutch that leaves here for Bench or Crew, Tire size, riding preferences = plowing, towing, slow trail, rock crawling, etc. (see prompts at checkout)
