It includes six lug holes with a diameter of 0.602 inches, ensuring secure mounting on compatible vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Improving braking performance on Ford F-150 and Lincoln Mark LT
• Resolving uneven brake pad wear due to rotor surface issues
• Upgrading to OEM-equivalent vented rotors for heat management

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 1.122 inches to maintain safety standards. Use proper torque specifications for the six lug bolts to avoid rotor distortion. Since this rotor does not include bearings or an ABS tone ring, confirm compatibility with your vehicle’s existing components. It is recommended to replace rotors in pairs to maintain balanced braking performance.
