Wiseco Piston 85.00mm Dual Ring – Arctic Cat 800 (3347KD)

The Wiseco 3347KD (kit 2466M08500) is a forged 85.00mm dual-ring piston engineered as a direct replacement for the 2018 Arctic Cat 800-series C-TEC2 twin. Wiseco forges its snowmobile pistons from high-strength aluminum for better heat and fatigue resistance than cast OEM units, making this a strong choice for a top-end rebuild or a durability upgrade on high-hour sleds.

Before you buy

This is a size- and model-specific piston — verify your bore size and that no prior oversize rebuild has been done. Check the kit contents (piston, ring set, wrist pin, and circlips) against what your rebuild requires, and always measure your cylinder before final ring and piston selection.
