The NEW MCB Pro-Series RZR 1000 Polaris pistons have been designed with ULTIMATE DURABILITY in mind. These FORGED Custom MCB pistons feature full round skirt design to dramatically improve bore stability, increase ring sealing/life, improve oil-ring control and offer extensive internal milling to reduce localized mass.

In addition to these features our new pistons offer a state of the art reverse dome profile, ultra flat ring lands, and improved pin oiling. Extended high RPM requires a fine balance between piston weight while maintaining stability and pin deflection. Our custom RZR 1000 piston accomplishes this while enhancing the all important ring seal at the same time. we have also engineered oil cooling reliefs in to the skirt profile to aid in the factory use of piston dome temperature control.

For those looking to increase power later, our RZR 1000 pistons are so durable you can use these in MILD (up to 7 lbs) boosted applications with the proper head gasket!

Last but not least, MCB includes PREMIUM ring sets that feature Gas Nitrided top rings, Napier second rings and Flex-vent oil control rings all of which will greatly improve the ring seal and life of your engine.

Fits most all 1000RZR (NOT PRO)

INCLUDED:
-(2) Custom design MCB FORGED reverse dome, full round skirt pistons in 11.25-1 compression ratio, with oil squirt cooling reliefs. This last mentioned feature makes for a PTO and MAG specific piston (see photos)
-(2) Premium ring sets
-(2) HD Alloy piston pins and locks
-(1) Superior quality Top-End gasket kit

Customers MUST ensure that your bore condition and sizing has been properly measured and verified. This is critical for any top end rebuild and if it is out of spec. see our cylinder exchange section for a replacement.

The Polaris Pro-Star 900/1000 engines used in the RZR and RANGER vehicles are the most mass produced engines in the UTV industry. These engines have a reputation for producing reasonable power and mediocre reliability. MCB has done extensive research and testing and are confident in what we believe is the BEST replacement Piston/Ring available for these engines.
