The Supra-Fin™ surface finishing process microscopically polishes the surface of any steel. Using a combination of chemical and mechanical surface improvements means the Supra-Fin™ process can improve life, wear, friction, noise and heat in any metal to metal contact application. 

This process helps by removing microscopic ridges created by cutting and grinding. The results mean break in times are virtually eliminated and installed parts are ready to run.

This process does not significantly affect the metalurgical properties of the part being processed. Hardness remains the same as well as the chemical properties of the alloy. Dimensionally, the parts also remain intact, with less than .0001" typically being removed.

This process can be added to any ring and pinion gear at purchase of a third member or when buying replacement ring and pinion.
