Nachman 09-716 OEM-Style Teflon Coated Piston Kit with Rings Standard Bore

The Nachman 09-716 is an OEM-style standard bore piston kit designed as a direct replacement for Polaris Indy 597cc triple-cylinder two-stroke snowmobile engines. Built to match original equipment specifications, this kit restores proper compression and engine performance during a top-end rebuild.

The piston features a Teflon coating on the skirt, which reduces friction during the critical break-in period and promotes longer service life under demanding operating conditions. The kit is supplied at standard (STD) bore size — 65mm — making it the correct choice for cylinders that are unworn or have been honed back to factory dimensions.

• 1 x Teflon-coated cast piston (OEM-style)
