Supertech uses an enhanced 4032 alloy with extruded high silicon. Additional copper, nickel, and magnesium is added to prevent thermal expansion, produce excellent wear characteristics, and increase thermal conductivity.\u003cbr\u003e\u003cbr\u003eThe forging is a 2 to 3 step process that yields a fine structural grain orientated in fibers in the same direction of the stresses. Several heat treatments provide the piston with high tensile strength that is evenly distributed.\u003cbr\u003e\u003cbr\u003eThe surface of each piston are coated with a phosphate dry lubricant to protect the rings from micro welding to the pistons and enhance the lubrication of the skirt\/cylinder area.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eNote: Pictures may not be actual product.\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecs:\u003c\/b\u003e\u003c\/p\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\n\u003cul\u003e\n\u003cli\u003eBore: 83.50mm\u003c\/li\u003e\n\u003cli\u003eOversize: +0.5mm\u003c\/li\u003e\n\u003cli\u003eComp.
