* Pistons are forged for maximum strength.
* Precision tolerance CNC machined for quality and performance.
* Honed pin bore holes for a precise tolerance fit between piston pin and piston.
* Complex piston skirt profiles that reduce power-robbing friction, yet promote stability in bore for optimum ring seal.
* Precision machined ring grooves featuring excellent surface finish and flatness providing maximum ring seal and minimizes blow by and oil consumption.
*The #1035 94mm Wiseco Forged Piston Set is the #1 choice for Turbo Engines. The kit features a 2mm gas nitrited barrel faced top ring, 2mm Taper faced Napier cast iron 2nd ring, 4mm 3 piece oil assembly with stainless steel flex vent spacers and gas nitrited rails.
