Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed to meet the braking demands of Ford Bronco II, Explorer, and Ranger vehicles. Its vented rotor construction allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps to evacuate gases, dust, and water, which can improve brake pad contact and reduce brake fade under heavy use.

With a nominal thickness of 22 mm and a discard thickness of 20.6 mm, this rotor provides a balance between durability and performance. The zinc silver hat finish offers corrosion resistance, extending the rotor's service life. The rotor's 5 bolt holes with a 1/2-20 diameter and a 114.3 mm bolt circle diameter ensure proper fitment and secure mounting on compatible Ford models.
