MCB Stage-1 Piston kit. Ski-Doo 600R 2018-2024 (MONOBLOCK ONLY) replaces 420893892 & 420893895

MCB Performance is proud to release its NEW in 2022 Top End kit for the Ski-Doo 600R (etec) engines.

Our custom 600R piston was designed with ultimate durability in mind and no compromises in power. Our proprietary FORGED piston incorporates a low-drag skirt profile in conjunction with Dura-Coat piston skirt coating. MCB has also added a second ring to further enhance durability and MORE importantly transfer critical dome heat to the cooling system.

Because the 600 class Engines rely on smaller bore sizes and lighter rotating components, weight becomes a concern with regards to dynamic balance. Keeping this priority, MCB has carefully engineered final machining to produce a piston and Dual-Ring combination that weighs 316.2 grams, factory weight is 314.4 grams. Direct interchangeability!

Lastly MCB has chosen to Type III Hard-Coat anodize the domes of these custom pistons to allow a margin of error with poor fuel quality and availability as we recognize many of these will be used for long distance/remote operations.

All MCB Stage-1 kits include Pistons, Ring sets, Pins, Circlips, Pin BEARINGS, Top-end gasket set and helpful tips / guidelines sheets.
