Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is a vented disc brake rotor designed to meet the braking demands of heavy-duty trucks and SUVs. The rotor features a directional surface with both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade. The vented design enhances airflow through the rotor, allowing for better heat dissipation during prolonged or aggressive braking.

The rotor's nominal thickness is 32.64 mm, with a discard thickness of 30.86 mm, ensuring a long service life before replacement is necessary. The zinc silver coating on the hat provides rust resistance, helping to maintain structural integrity and appearance over time. With an outside diameter of 317 mm and an overall height of 71 mm, this rotor is engineered to fit specific Chevrolet, GMC, and Jeep models equipped with an 8-lug wheel pattern and a bolt circle diameter of 165.1 mm.
