Endurance and high rpm. Each piston is electra-coated on the dome, ring groove, and pin bore, for maximum wear resistance and protection from micro-welding, galling and detonation. GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression. ArmorGlide® skirt coating reduces friction and noise for more horsepower potential. Kit includes piston, ring(s), wrist pin and circlips. Engineered, forged, and machined in the USA.
