The WOSSNER Piston Kit is designed for Polaris 850 Patriot applications and features an 84.85 mm piston size. Hardcoat anodizing enhances piston durability, heat management and wear resistance. The piston is machined for lightness while maintaining strength in key areas, including the crown and skirt wall cross sections.
External machining is optimized to help prevent port venting in extreme applications with race porting. The kit includes the piston, rings, wrist pin and retaining clips unless noted. Distributor part number: K7080DA-2. Manufacturer part number: K7080DA-2.
