The WISECO Piston Kit 66.40 mm is designed for endurance and high-rpm performance. Each piston features an electra-coated dome, ring groove, and pin bore to enhance wear resistance and help protect against micro-welding, galling, and detonation. The GP Series design generally uses less machining on the outside of the piston, helping seal the bore for increased compression.
ArmorGlide® skirt coating helps reduce friction and noise for increased horsepower potential. This kit includes the piston, ring(s), wrist pin, and circlips. The piston is engineered, forged, and machined in the USA. Distributor part number: 824M06640. Manufacturer part number: 824M06640.
