Detailed Product Description

This disc brake rotor set is specifically designed for the rear brakes of the Ford F-350 Super Duty. Featuring a vented rotor type, it allows air to flow through the rotor, reducing heat buildup during braking. The drilled and slotted surface enhances braking efficiency by improving pad bite and helping to clear water, dust, and brake dust from the rotor surface. The zinc plating adds a rust-resistant coating, extending the rotor's service life in harsh environments. With a nominal thickness ranging from 32.40 mm to 34.00 mm and a discard thickness of 1.28 mm, these rotors provide clear guidelines for maintenance and replacement. The rotor's dimensions, including an outside diameter of 340.10 mm and an overall height of 125 mm, ensure proper fitment and compatibility with the Ford F-350 Super Duty rear brake assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rear brake rotors on Ford F-350 Super Duty
