Design:
More than 35 years of experience in the design of racing pistons and the utilization of the latest CAD software & Finite Element Analysis (FAE) enables us to design strong high performance and yet light pistons for each application.

Manufacturing:
Our pistons are manufactured from extruded high silicon, enhanced 4032 alloy (with additional Cu, Ni & Mg) that has low thermal expansion, excellent wear resistance and higher thermal conductivity. We have successfully used this alloy in our pistons for turbo charged engines using alcohol, up to 42 psi of boost.

A 2 or 3 forging step process yields a fine structural grain oriented in fibers in the same direction of the stresses. Several heat treatments provide the piston with a high tensile strength and evenly distributed hardness.

The pistons are submitted to several machining steps in specially designed machines and in conventional CNC machines with special Diamond tools for dimensional precision, perpendicularity and flatness of the ring grooves. Contact reduction grooves are standard. Honed & reamed pin bores for precise fit.
Wrist pins are constructed of cold extruded Chrome Moly steel for high strength to be used with wire clip locks.

Surface Finish:
Finally our “phosphate dry lubricant” coating is applied to protect the rings against “micro welding” and enhance lubrication on the skirt/ cylinder area.

Piston Rings:
are manufactured in Japan with the latest technology for high performance applications.

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