With a nominal thickness of 36.00 mm and a discard thickness of 34.40 mm, it maintains structural integrity under heavy braking conditions. The rotor’s outside diameter of 345.00 mm (13.60 inches) and overall height of 90.50 mm ensure proper fitment and clearance. The mounting bolt hole circle diameter of 165.10 mm and 8 lug holes provide secure installation on compatible Ford rear hubs.

Applications and Problem Solving

• Replacement for worn or warped rear rotors on Ford E-150, E-250, and E-350 Super Duty
• Addresses brake pulsation caused by uneven rotor surfaces
• Helps reduce brake noise and vibration
• Prevents rust-related rotor degradation with Geomet coating
• Improves braking consistency under heavy load or towing conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 34.40 mm before installation. Clean the mounting surface and hub to remove rust or debris for proper rotor seating. Use the correct torque specifications on the 8 lug bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet OEM standards and undergo rigorous quality control to ensure durability and performance. The Geomet coating provides additional protection against corrosion, extending rotor life. Warranty details should be confirmed with the manufacturer or distributor, as coverage may vary.
