Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on delivering rotors with enhanced surface features to improve braking efficiency. The drilled and slotted design helps evacuate gases, dust, and water from the rotor surface, which is critical for maintaining consistent brake performance in demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life especially in harsh environments.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow between the rotor faces, reducing heat buildup during braking. The directional surface pattern combines drilled holes and slots to optimize pad contact and improve debris removal. With a bolt hole quantity of eight and a bolt hole diameter of 16.3 mm, it matches the factory specifications for the listed Chevrolet and GMC heavy-duty models. The rotor's nominal thickness is 40 mm, with a discard thickness of 38.5 mm, ensuring safe replacement intervals. The overall diameter of 355 mm and height of 102.5 mm align with OEM dimensions for proper fitment.
