Supertech pistons are manufactured from extruded high silicon, enhanced 4032 alloy that low thermal expansion, excellent wear resistance and higher thermal conductivity. A phosphate dry lubricant coating is applied to pistons to protect against ring micro welding and enhance skirt lubrication.

Features:

Forged from enhanced 4032 alloy and CNC machined

Contact reduction grooves are standard

Honed & reamed pin bores and precise fit

High tensile strength and evenly distributed hardness

Withstands up to 42psi of turbo boost, w/alcohol, w/out any problems

A 2 or 3 forging steps process yeilds a fine structural grain oriented in fibers in the same direction of the stresses.

Wrist pins are constructed or cold extruded chrome molly steel for high strength to be used with the wire clip locks.

Quality Control is performed after every step of the manufacturing process in climate controlled environments to ensure reliability of dimensions

Rings, wrist pins, and wire locks are included.
