Detailed Product Features and Specifications

This Dynamite Friction rotor features a 325 mm outside diameter and an overall height of 85.3 mm, designed to meet OEM specifications for proper fit and function. The rotor’s drilled and slotted surface improves brake pad bite and helps evacuate gases and debris, reducing brake fade during heavy use. The vented design promotes airflow to dissipate heat efficiently, extending rotor and pad life. The zinc silver coating on the hat area provides corrosion resistance, helping maintain structural integrity and appearance over time. With six bolt holes measuring 16.4 mm in diameter and a center hole diameter of 78.7 mm, this rotor is engineered for precise fitment on compatible Chevrolet and GMC vehicles.
