The vented rotor construction helps dissipate heat more effectively, reducing the risk of brake fade during demanding driving conditions common in Ford Excursion, F-250 Super Duty, and F-350 Super Duty trucks. The rotor’s zinc silver hat finish provides corrosion resistance, extending the rotor’s service life in various environments.\u003c\/p\u003e\u003cp\u003eThe rotor’s dimensions, including an outside diameter of 331 mm and an overall height of 99.5 mm, ensure compatibility with the specified Ford models. The eight bolt holes with a 16.2 mm diameter and a 170 mm bolt circle diameter align with factory mounting points for straightforward installation. The nominal thickness of 38 mm and discard thickness of 36 mm provide clear guidelines for maintenance and replacement.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This line is designed to improve braking performance by enhancing heat dissipation and maintaining clean pad surfaces, which is particularly beneficial for heavy-duty trucks like the Ford Excursion and Super Duty series. The silver zinc coating on the rotor hat adds an extra layer of protection against rust, making these rotors suitable for long-term use in various driving conditions.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during towing or heavy load conditions on Ford F-250 and F-350 Super Duty trucks\u003c\/li\u003e\n\u003cli\u003eImproves braking response and pad bite on Ford Excursion models\u003c\/li\u003e\n\u003cli\u003eMinimizes rotor surface glazing and pad deposits through slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents premature rotor corrosion with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity under high heat with vented rotor design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 36 mm to maintain safe braking performance. Use the correct torque specifications for the eight 16.2 mm bolt holes to secure the rotor properly. This rotor is directional; confirm the correct orientation during installation to optimize braking efficiency.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-54174L rotor to meet or exceed OEM specifications for Ford Excursion, F-250 Super Duty, and F-350 Super Duty vehicles.
