This line emphasizes durability and consistent performance, making it suitable for heavy-duty applications such as the Ford F-250 Super Duty and F-350 Super Duty. The 680344R rotor benefits from this engineering approach, providing a vented rotor design that supports effective heat management and long service life.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design to improve cooling during braking, reducing the risk of brake fade under heavy loads. The drum-in-hat configuration integrates a parking brake drum within the rotor, eliminating the need for a separate drum assembly. With an outside diameter of 13.380 inches and a nominal thickness of 1.345 inches, the rotor maintains structural integrity while providing consistent braking surface. The discard thickness of 1.276 inches indicates the minimum safe thickness before replacement is necessary. The rotor mounts with eight bolts on a 6.142-inch bolt circle diameter, ensuring secure fitment on compatible Ford Super Duty models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by overheating during heavy towing or hauling\u003c\/li\u003e\n\u003cli\u003eResolves issues with uneven braking or pulsation due to rotor thickness variation\u003c\/li\u003e\n\u003cli\u003eRestores parking brake functionality with integrated drum-in-hat design\u003c\/li\u003e\n\u003cli\u003eImproves braking reliability and safety on heavy-duty trucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 1.276 inches.
