Vehicle Fitment

• 2005-2012 Ford F-250 Super Duty (XL, XLT, Lariat, King Ranch, FX4, Harley-Davidson Edition, Cabela's | 5.4L V8 Gas, 6.0L V8 Diesel, 6.4L V8 Diesel, 6.8L V10 Gas | 2WD, 4WD | SRW, DRW)
• 2005-2012 Ford F-350 Super Duty (XL, XLT, Lariat, King Ranch, FX4, Harley-Davidson Edition, Cabela's | 5.4L V8 Gas, 6.0L V8 Diesel, 6.4L V8 Diesel, 6.8L V10 Gas | 2WD, 4WD | SRW, DRW)

Fitment Notes

• Fits both Single Rear Wheel (SRW) and Dual Rear Wheel (DRW) configurations.
• Compatible with 2WD and 4WD drivetrains across all listed trims.
• Directional rotor - sweeping slots and dimple pattern must point toward the rear of the vehicle upon installation.
• Designed for street use only; not intended for racing, rally, or track day use.

Features

• Dimpled and slotted 3GD Series design reduces rotor temperatures by up to 100°F compared to non-slotted rotors, significantly reducing brake fade under heavy use.
• Blind-drilled dimples degas brake pads without through-drilling, eliminating the stress crack risk associated with fully drilled rotors.
• Wide-aperture scraper slots draw cool air into the pad-rotor interface and expel heat, dust, dirt, and debris for consistent braking performance.
• Slotted surface maintains flat and parallel pad wear, maximizing pad-to-rotor contact throughout the service life.
• Silver corrosion-resistant finish protects non-swept areas from rust and provides a clean, performance appearance.
• Precision-machined from premium grey iron castings with 100% runout and dimensional inspection before release.
• Passed European R90 brake safety certification standards, ensuring consistent performance under rigorous conditions.

Product Description

The EBC GD7321 3GD Series Sport Rotors are a direct-fit rear brake upgrade for 2005-2012 Ford F-250 and F-350 Super Duty trucks across all major trims and engine configurations, including 2WD and 4WD in both SRW and DRW setups. Engineered with wide-aperture slots and EBC's signature blind-drilled dimples - a design EBC pioneered - these rotors actively cool the braking surface while degassing pads without the cracking risks associated with fully drilled rotors. The result is a rotor that runs cooler, lasts longer, and performs more consistently under the heavy braking demands of towing, hauling, and daily driving.

Precision-machined from OE-spec grey cast iron and finished with a silver corrosion-resistant coating, the GD7321 rotors are built to EBC's strict dimensional and runout standards. They install directly in place of factory rotors with no modifications required and are compatible with stock calipers. EBC recommends pairing these rotors with EBC Greenstuff or Yellowstuff brake pads for optimal performance and to protect the rotor surface during break-in. A 500-mile break-in period with moderate braking is advised before full-load use.
