Wiseco 4 Stroke Forged Series Piston Kit, 77.00 MM Bore, 13.2:1 CR

The Wiseco PK1846 Top End Kit includes a piston, rings, wrist pin, clips, and a gasket kit. These pistons are built from race-proven designs, chosen by top race teams, and feature dedicated forgings for superior strength-to-weight ratio, utilizing aerospace alloy construction. They include a high-performance ring set and alloy pin for extended life and sustained power, aiming for maximum compression and oil control, improved combustion flow, horizontal slot pin oiling for reduced friction, and a pressure seal groove for maximum ring seal. Some Wiseco pistons also feature ArmorGlide skirt coating for reduced friction, noise, and increased horsepower, allowing for a tighter piston fit, improving ring seal and reducing piston rock noise.
