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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern. This design enhances braking efficiency by allowing gases, dust, and heat to escape more effectively than plain rotors. The zinc silver hat finish adds a layer of corrosion resistance, extending rotor life in harsh environments. This product line is tailored for heavy-duty applications, making it suitable for Chevrolet and GMC trucks and vans requiring reliable, consistent braking performance.

Product Specifications and Features

This disc brake rotor features a vented design with a 325 mm outside diameter and an overall height of 89.3 mm. The rotor surface is both drilled and slotted in a directional pattern, which improves pad contact and helps maintain cooler operating temperatures. The rotor’s nominal thickness is 38 mm, with a discard thickness of 36.5 mm to ensure safe replacement intervals. The hat is finished in zinc silver and includes a rust-resistant coating to protect against corrosion. It has eight bolt holes with a diameter of 16.4 mm and a bolt circle diameter of 165.1 mm, matching the stud/lug hole pattern for secure installation.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Avalanche 2500 and GMC Sierra 2500 HD models
• Improves braking performance in heavy-duty Chevrolet Silverado 3500 and GMC Savana 3500 vans
• Reduces brake fade caused by heat buildup during towing or hauling
• Helps eliminate brake noise and vibration associated with uneven rotor surfaces
• Protects against rust and corrosion in environments exposed to moisture and road salt

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (36.5 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven contact
• Use proper torque specifications for the eight 16.4 mm bolt holes to secure rotor
• Check compatibility with Chevrolet Avalanche 2500, Express 2500/3500, GMC Savana 2500/3500, Sierra 2500 HD/3500, and Silverado 2500 HD/3500 models before installation
• Inspect brake pads for wear and replace if necessary to maximize rotor performance
