Detailed Product Features and Specifications

This Dynamite Friction rotor features a vented design that helps reduce heat buildup during heavy braking, which is critical for the demanding conditions faced by Ford Excursion, F-250 Super Duty, and F-350 Super Duty trucks. The drilled and slotted surface improves brake pad bite and helps evacuate gases, dust, and water, maintaining consistent braking performance. The rotor’s directional surface ensures proper rotation for optimal wear and heat dissipation.

The rotor’s nominal thickness is 38 mm, with a discard thickness of 36 mm, indicating when replacement is necessary to maintain safety. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life. With eight bolt holes sized at 16.2 mm and a bolt circle diameter of 170 mm, this rotor matches the factory specifications for the listed Ford models.
