Stock rear rotors on the 2015-2020 F-150 2.7 EcoBoost 2WD do their job until they don't, and replacement quality varies wildly in the aftermarket. EBC's RK7603 Premium Rotors are cast from G3000 spec gray iron, machined to tight runout tolerances, and finished in a Gen 3 silver-grey Geomet-style coating that resists corrosion far better than the black etch paint used on earlier production runs.
Gen 3 silver-grey coating sets a new standard. EBC transitioned to this Geomet-style surface finish in early 2023. The coating is applied at the casting facility immediately after machining and washing, leaving zero time for surface oxidation to develop on bare iron. The result is a highly corrosion-resistant finish that stays silver at the hat and hub area even after bedding in, so the rear axle continues to match the appearance of the front if only one axle is being replaced.
G3000 spec iron and 100-percent runout inspection. Every rotor EBC produces passes through a dedicated runout inspection machine before it ships. No rotor leaves the facility unchecked. The G3000 cast iron specification ensures consistent hardness, thermal stability, and friction compatibility across the full operating range of the 2.7 EcoBoost drivetrain. This is not a commodity import casting.
Produced in controlled manufacturing environments. Over 80 percent of EBC rotor castings originate from European foundries, and all machining for sport rotors is completed in either the United Kingdom or the United States. The coating process is integrated directly into the casting plant, in an air-quality-controlled environment, which is more environmentally responsible than off-site finishing operations.
