Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed to meet the braking demands of Ford Ranger and Mazda B-series trucks including B2300, B3000, and B4000 models. The rotor features a directional surface with both drilled holes and slots, which help evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade under heavy braking conditions.

The rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively than solid rotors. This helps maintain consistent braking performance during towing, hauling, or off-road driving. The zinc black finish on the rotor hat provides corrosion resistance, extending the rotor’s service life in harsh environments.

With a nominal thickness of 26.1 mm and a discard thickness of 24.5 mm, this rotor meets OEM specifications for thickness and durability. The 5-lug bolt pattern with a 114.3 mm bolt circle diameter and 1/2-20 bolt hole diameter ensures proper fitment on compatible Ford and Mazda trucks.
