This clearance also ensures optimal piston-to-cylinder contact for consistent power delivery.

Each piston kit comes complete with piston rings, piston pin retainers, and new piston pins. The rings are made from high-quality materials and are designed to provide optimal sealing and durability. The piston pins are made from heat-treated chrome molybdenum steel for maximum strength and durability.
