Technical Description and Specifications

This vented disc brake rotor features a smooth surface type designed to reduce noise and vibration during braking. The nominal thickness of 1.417 inches (36.000 mm) ensures structural integrity, while the discard thickness of 1.354 inches (34.400 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter measures 13.583 inches (345.000 mm), with an overall height of 4.213 inches (107.000 mm), matching OEM specifications for the Ford E-350 Super Duty and Econoline Van/Wagon models. The rotor includes eight stud/lug holes with a diameter of 0.512 inches (13.000 mm) and a mounting bolt hole circle diameter of 5.709 inches (145.000 mm). It does not include an ABS tone ring or bearings, so these components must be sourced separately if required.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford E-350 Super Duty and Econoline models
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores braking efficiency lost due to rotor thickness below discard limits
• Improves heat dissipation in heavy-duty braking scenarios with vented design
• Eliminates noise and vibration from damaged or uneven rotors

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets nominal specifications
• Clean rotor surface and hub mounting area to prevent uneven contact
• Use proper torque specifications on lug nuts to avoid rotor warping
• Check compatibility with existing brake pads and hardware
• ABS tone ring not included; confirm ABS system requirements before installation
