MMR Oil Pump gears feature larger clearances than factory specifications; these clearances have been optimised for the superior material we have chosen and are purposely engineered into our gears. These increased clearances are similar to those of a factory piston versus an Aftermarket forged piston, which requires more clearance to improve reliability in performance applications.
