The drilled and slotted surface enhances water and debris evacuation, maintaining consistent contact between the brake pad and rotor. The rotor’s directional surface is engineered to optimize braking efficiency and minimize noise. The zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 38 mm and a discard thickness of 36.4 mm, this rotor meets precise wear limits for safe operation. The eight bolt holes, each 13 mm in diameter, and a bolt circle diameter of 156 mm ensure proper fitment on the Ford F-350 Super Duty.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking performance and rotor cooling. This product line is designed for vehicles requiring enhanced heat dissipation and debris removal, making it suitable for heavy-duty trucks like the Ford F-350 Super Duty. The silver zinc coating adds rust resistance, helping maintain rotor integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Ford 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 excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking in wet or dirty environments\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust-resistant coating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is measured before installation; replace if below the discard thickness of 36.4 mm. Confirm bolt hole alignment with the vehicle’s hub using the 156 mm bolt circle diameter and 13 mm bolt hole diameter. The directional surface requires correct orientation during installation to maintain braking efficiency. Clean the rotor surface of any protective coatings or debris before mounting to ensure proper pad contact.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for the Ford F-350 Super Duty.
