The coated hat finish protects against corrosion, extending rotor life and maintaining appearance.

Product Details and Specifications

This StopTech rotor features a floating disc mounting system that allows for thermal expansion and contraction, minimizing warping under high temperatures. The rotor measures 336 mm in outside diameter with a nominal thickness of 22 mm, ensuring compatibility with Ford F-150 brake systems. The vented design includes 50 straight vanes to optimize airflow and cooling. The hat section is coated to resist rust, and the rotor includes five lug holes sized at 15.6 mm diameter on a 135 mm bolt circle diameter. Note that this rotor does not include ABS tone rings or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford F-150 trucks
• Improves braking performance under heavy load or towing conditions
• Reduces brake fade during extended downhill driving or repeated stops
• Helps eliminate brake noise and vibration caused by rotor surface irregularities
• Prevents corrosion-related rotor damage with coated hat finish

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (20.0 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven contact
• Use proper torque specifications for lug nuts to avoid rotor warping
• Check compatibility with existing brake pads and calipers on Ford F-150
• Verify absence of ABS tone ring requirement as this rotor does not include one
