Molybdenum disulfide (MoS2) coated aluminum piston.
Coating provides a slick, sacrificial lubricant surface compared to bare aluminum.
Designed to reduce friction, cylinder wall contact and skirt wear while coating remains.
Intended to reduce heat, friction and plating wear over time.
Equipped with stiffer cast iron piston rings.
Includes pin clips.
Commonly used in performance applications such as ATVs, dirtbikes and outboards.
