Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black is designed to meet the braking demands of Chevrolet Blazer, GMC Jimmy, Jeep Cherokee, and other compatible models including K5 Blazer, K10, K1500, and Wagoneer variants. The rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent brake performance and reduces the risk of brake fade.

The drilled and slotted surface enhances water and debris evacuation from the rotor face, improving wet weather braking and pad bite. The directional pattern ensures optimal contact with brake pads, while the zinc black hat finish and rust resistant coating protect against corrosion, extending rotor life. With a nominal thickness of 32.76 mm and discard thickness of 30.86 mm, this rotor maintains structural integrity under demanding conditions.
