Our Surface Finish
Supertech takes great pride in what we call our pistons surface finish. This finish is our "phosphate dry lubricant" coating that is applied to protect the rings against "micro welding" and enhance lubrication on the skirt/cylinder area.
Our Piston rings are manufactured in Japan with the latest technology for high performance applications. We have quality control in place at every step of the manufacturing process in a climate controlled environment to ensure reliability of dimensions.
