MCB Performance's new direct replacement Dual-Ring Piston for all 2001-2007 Ski-Doo 800cc twin-cylinder motors has a dual-ring Alloy steel, ferrox coated chrome faced design that gives superior durability and prevents ring flake and piston failures that can be common with stock 800cc piston design. The new piston is a hypereutectic cast design with increased silicon content. It has increased hardness, is more resistant to wear, less prone to cold seizure and has an increased ability to withstand higher cylinder temperatures, pressure and detonation. The piston skirts are coated with MOS2 (telfon-molybdenum coating), which is composed of sub-micron sized particles of solid lubricant and resin blend solvents. The coating is applied through a roll impregnated process, not sprayed on, providing 10 times the bond strength. MCB says the advantage of the dual ring design is the ability to draw heat through the top portion of the dual ring piston walls and out the bottom, reducing heat and friction, and prolonging ring life. The coatings help eliminate cold seizure and increases durability. The piston dome top is HRB-105 hard anodized, making it 75% stronger than non-anodized pistons.

MCB offers pistons of this same technology for all Brands of Arctic Cat, Polaris, Ski Doo, and Yamaha snomobiles.

The pistons are available individually or in complete kits that include both pistons, all four rings, wrist pins, circlips, caged wrist pin bearings and a complete  top-end gasket kit. Complete kits are $299.00, individual pistons are $125.

All MCB pistons are MOS2 coated; proven to be the best for durability and lubricity.  The piston material is high silicone content to give the necessary hardness that aluminum pistons need.  The piston-tops are hard anodized for heat resistance and to minimize piston expansion/contraction; this combined with the coating virtually eliminates the possibility of cold seizure.  All pistons are EXACT OEM dimensions and mass, including ring grooves (we actually use OEM rings).  These pistons offer equal or BETTER than OEM performance at significantly less cost.  All kits include everything necessary to rebuild your sled.  Pistons, rings, wrist pins, circlips, and a complete gasket kit.

NOTE:  All '03 REV's stock pistons and rings are widely known to have premature ring failure, known as "ring flake".  Update your sled before catastrophic failure occurs.
