This rotor features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during demanding driving conditions. The drilled and slotted surface improves water and debris evacuation, maintaining consistent braking performance in wet or dirty environments. The directional brake surface ensures optimal pad contact and braking efficiency.\u003c\/p\u003e\u003cp\u003eThe rotor’s hat is finished in zinc silver, providing a rust-resistant coating that extends the rotor’s service life by protecting against corrosion. With a nominal thickness of 38 mm and a discard thickness of 36 mm, this rotor meets strict durability standards. The eight bolt holes with a 16.2 mm diameter and a 170 mm bolt circle diameter ensure precise fitment and secure mounting on compatible Ford Super Duty models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty trucks\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat during towing or heavy loads\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or muddy conditions with slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on brake components for longer service intervals\u003c\/li\u003e\n\u003cli\u003eRestores smooth and consistent braking response for safer driving\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 hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the eight 16.2 mm bolt holes to secure the rotor firmly. The directional surface requires installation in the correct rotation direction to maintain optimal braking performance. Always inspect brake pads and hardware during rotor replacement for best results.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction’s DFC Brake Rotor - Drilled and Slotted - Silver line is manufactured to meet OEM specifications for Ford Super Duty trucks.
