Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Black is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced braking efficiency through advanced surface treatments. This rotor features a vented design that helps maintain optimal operating temperatures during demanding driving conditions, such as towing or hauling. The drilled and slotted surface improves water, dust, and gas evacuation, reducing the risk of brake fade and maintaining consistent pedal feel.

Its zinc black hat finish provides corrosion resistance, extending the rotor's service life, especially in harsh environments. The rotor is directional, meaning it is designed to rotate in a specific direction to maximize performance. With an 8-bolt hole pattern and a bolt circle diameter of 165.1 mm, it fits a range of Chevrolet and GMC heavy-duty models including Avalanche 2500, Express 2500/3500, Savana 2500/3500, Sierra 2500/3500 HD variants, Silverado 2500/3500 HD variants, Suburban 2500, and Yukon XL 2500.

Applications and Problem Solving

• Replaces worn or warped rotors on Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD
• Improves braking performance under heavy load and towing conditions
• Reduces brake fade caused by heat buildup during extended braking
• Minimizes rust and corrosion on rotor hats for longer service intervals
• Enhances water and debris evacuation for consistent braking in wet conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional side facing the correct rotation direction as indicated by the manufacturer. Verify that the bolt hole pattern and diameter match your vehicle’s specifications. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance. Proper torque specifications should be followed for all mounting bolts to avoid rotor warping.
