New skirt coating technology is applied to the entire thickness of the piston-to-wall clearance for a zero install clearance; coating then abrades in on start-up to hone for the perfect fit per cylinder
Skirt coating eliminates piston rock for the best possible ring seal with no piston slap noise
Hard anodized crown to aid in heat deflection and to reduce corrosion from alcohol fuels
Hard anodized top ring groove eliminates micro welding of the ring to the groove; this maintains a flat and smooth surface for the best ring seal and top ring groove
Includes piston, rings, pins and clips
Made in the U.S.A.
