Detailed Product Description

The Raybestos Element3; Coated Rotor 680394FZN is engineered to meet the exacting standards required for heavy-duty Ford trucks such as the F-250 Super Duty and F-350 Super Duty. This rotor features a drum-in-hat design, which integrates the parking brake drum into the rotor itself, reducing the need for separate components and simplifying installation. The nominal thickness of 1.340 inches (34.050 mm) ensures optimal rotor durability and heat dissipation, while the discard thickness of 1.280 inches (32.500 mm) provides a clear wear limit to maintain safe braking performance. The mounting bolt hole circle diameter and bolt hole diameter both measure 5.000 inches (127.000 mm), ensuring precise fitment and secure attachment to the vehicle hub.

About the Element3; Coated Rotor Product Line

The Element3; Coated Rotor line by Raybestos is designed to provide enhanced corrosion resistance and extended rotor life through a specialized coating process. This coating helps protect the rotor surface from rust and environmental damage, which is particularly beneficial for trucks like the Ford F-250 Super Duty and F-350 Super Duty that are often exposed to harsh conditions. The 680394FZN rotor benefits from this coating, contributing to consistent braking performance over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty
• Addresses brake pulsation caused by uneven rotor thickness
• Resolves noise issues related to rotor surface corrosion
• Improves braking consistency in heavy-duty towing or hauling scenarios
• Supports parking brake functionality with integrated drum-in-hat design

Installation Notes and Tips

• Verify rotor thickness before installation; do not install if below discard thickness of 1.280 inches
• Ensure mounting surfaces and bolt holes are clean and free of debris for proper fitment
• Use proper torque specifications for mounting bolts to avoid rotor warping
• Inspect brake pads and hardware during rotor replacement for optimal system performance
