Its vented rotor construction allows for improved airflow, which helps maintain optimal operating temperatures during heavy braking. The rotor features a directional surface pattern with drilled holes and slots that aid in heat dissipation and removal of brake dust and moisture. With an outside diameter of 331 mm and a nominal thickness of 38 mm, this rotor meets strict specifications to ensure proper fit and function. The zinc silver hat finish and rust-resistant coating provide additional durability against environmental elements. The rotor’s 8-bolt hole configuration with a 14x1.5 mm bolt hole diameter and 170 mm bolt circle diameter ensures compatibility with specified Ford models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Ford Excursion, F-250 Super Duty, and F-350 Super Duty\u003c\/li\u003e\n\u003cli\u003eImproves braking performance under heavy load or towing conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake fade caused by overheating during extended braking\u003c\/li\u003e\n\u003cli\u003eHelps prevent corrosion-related rotor damage with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking response in wet or debris-prone environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 36 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 8-bolt, 14x1.5 mm pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM standards for fit, form, and function.
