Detailed Product Description

The Raybestos Element3; Coated Rotor 680344FZN is designed specifically for Ford F-250 Super Duty and F-350 Super Duty trucks requiring a vented disc brake rotor with a drum-in-hat design. The vented rotor construction enhances heat dissipation during braking, reducing the risk of brake fade under heavy load or towing conditions. The drum-in-hat feature integrates a parking brake drum, eliminating the need for a separate drum and simplifying installation.

With an outside diameter of 13.380 inches and an overall height of 4.925 inches, this rotor matches OEM specifications for proper clearance and fit. The nominal thickness of 1.345 inches ensures structural integrity, while the discard thickness of 1.276 inches indicates the minimum safe thickness before replacement is necessary. The rotor includes eight mounting bolt holes arranged on a 6.142-inch bolt circle diameter, providing secure attachment to the hub. The center hole diameter of 5.044 inches ensures accurate centering on the vehicle hub.
