Stock rear rotors on the 2018-2020 F-150 2.7L EcoBoost 2WD handle everyday driving, but push into aggressive towing, loaded highway runs, or spirited backroad use and heat buildup starts to rob pedal feel. EBC's GD7784 GD Sport rotors give the rear axle a meaningful upgrade without changing the truck's daily-driver manners.
Wide-aperture slots that actively manage heat. The GD series slots are not decorative. Their geometry draws cooler air into the pad-to-rotor interface, where braking temperatures can exceed 1,000 degrees at the pad contact zone under hard use. Cooler running means more consistent friction, reduced fade, and better pedal confidence lap after lap or stop after stop on a loaded truck.
Dimple drilling without the cracking risk. EBC pioneered the dimple-drilled rotor concept in the 1990s as an alternative to through-drilling. Full through-holes concentrate stress at the drill points and can initiate cracks under thermal cycling. EBC's dimples provide the same pad degassing benefit, clearing gases that build up between pad and rotor during heavy braking, while leaving the rotor structure intact.
Third-generation corrosion protection. Every GD series rotor ships with a silver corrosion-resistant finish that keeps exposed surfaces from rusting between brake applications. Trucks see mud, water, road salt, and grit, and the coating handles all of it without compromising the braking surface.
Manufactured to ISO and TÜV standards. EBC machines the GD series 100% in the UK from R90-approved blanks, with castings sourced primarily from EU foundries. Every rotor passes a 100% runout inspection, dimensional check, and metallurgy review before it ships. All sport rotors are balanced and runout-inspected as a final release step.
Product Benefits
- Rear Fitment: Designed specifically for the 2018-2020 F-150 2.7L EcoBoost 2WD rear axle position.
- Wide-Aperture GD Slots: Draw cool air to the pad interface, reduce heat buildup, and expel dirt, mud, water, and dust.
- Dimple-Drilled Design: Promotes pad degassing without through-hole stress risers that can lead to rotor cracking.
- Corrosion-Resistant Finish: Third-generation silver coating protects non-braking surfaces from rust and environmental exposure.
- R90-Approved Blanks: 100% machined in the UK to meet European type-approval rotor standards.
- Full Quality Inspection: Every rotor undergoes 100% runout, metallurgy, and dimensional checks plus a final balance and runout release inspection.
- Even Pad Wear: Slot geometry promotes consistent pad contact across the full friction surface.
