Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is designed to meet the braking demands of Ford Ranger and Mazda B-series trucks including B2500, B3000, and B4000 models. The rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under heavy use. The drilled and slotted surface improves water and gas evacuation, maintaining consistent brake pad contact and performance in various driving conditions.

The rotor’s directional surface pattern is engineered to optimize braking force and reduce noise. Its zinc silver coated hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 26.1 mm and a discard thickness of 24.5 mm, this rotor maintains structural integrity and safety throughout its lifespan. The five 1/2-20 bolt holes and 114.3 mm bolt circle diameter ensure a secure fit on compatible vehicles.
