Detailed Product Description

This Dynamite Friction DFC Brake Rotor (part number 633-40078L) is specifically designed for the Dodge Ram 2500, ensuring precise fitment and optimal braking performance. The rotor features a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during heavy braking. The directional slotted and drilled surface improves pad bite and helps evacuate gases, dust, and water, which can otherwise reduce braking efficiency.

The rotor’s hat is finished with a zinc black coating to resist rust and corrosion, extending the rotor’s service life. With a nominal thickness of 32.7 mm and a discard thickness of 30.51 mm, this rotor meets strict durability standards. The eight bolt holes with a 9/16-18 diameter and a bolt circle diameter of 165.1 mm ensure secure mounting on the Dodge Ram 2500 hub assembly.
