Wiseco Piston Kit for the Polaris 850 Patriot 19-Current Dual Ring

Modern snowmobile engines are a feat of two-stroke performance engineering and they deserve the latest in two-stroke piston technology to match. Building on over eight decades of experience, Wiseco has developed purpose-designed forged pistons for Polaris Patriot 850 engines in a dual-ring configuration for performance and long life, featuring: Forged in the USA from 4032 aluminum alloy for high tensile strength and minimal thermal expansion Hard anodizing on piston crown, in ring groove(s), and in pin bores prevents ring microwelding and protects against potential damages caused by high heat and engine loads common in snowmobiles ArmorGlide skirt coating reduces friction, wear, and operating noise Dedicated forging designs and lightening operations optimize strength-to-weight ratio Kit includes one piston.
