Nachman 09-720 OEM-Style Piston Kit with Rings Teflon Coated Standard Bore - 70.50mm

The Nachman 09-720 is an OEM-style piston kit engineered as a reliable replacement for standard bore snowmobile engines. Built to match original equipment dimensions at 70.50mm (2.785 in.) standard bore, this kit delivers a precise, drop-in fit for a proper top-end rebuild.

The piston features a Teflon/MOS2 coating that actively draws heat away from the piston crown and through the piston walls, reducing operating temperatures and friction for improved power output and extended engine life. The hard anodized crown and hypereutectic cast construction provide excellent durability under the demanding thermal and mechanical stresses of two-stroke powersports engines.
