Get the best bearing treatment available in racing today!

Proven by independent testing labs, our premiere low friction bearing treatment occurs in a laboratory environment in order to transfer atoms to the treated part. Unlike ‘Coatings’ RF85 does not sit on the surface of the part so it will not chip, peel, wear off or change the dimensions of your metal part.

With 20 years worth of treatment applications, including Motorcycle racing, Indycar racing, and Weapons Manufacturing RF85 has been proven to reduce friction by up to 85%. Add Day Lube low friction grease to your treated bearings and you will have the best low friction solution on the market for your racecar.
