About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking efficiency through its vented design combined with drilled and slotted surfaces. This configuration helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life in harsh environments.

Detailed Product Description

This disc brake rotor features a 330 mm outside diameter and an overall height of 85.7 mm, making it suitable for heavy-duty applications. The rotor is vented to allow better airflow, which helps maintain optimal operating temperatures during braking. The drilled and slotted surface design improves water and gas evacuation, enhancing brake pad contact and reducing the risk of brake fade. The directional surface ensures the rotor is installed correctly for maximum performance. With eight bolt holes measuring 16.5 mm in diameter and a bolt circle diameter of 165.1 mm, this rotor fits securely on compatible Chevrolet, GMC, and Hummer models.

Applications and Problem Solving

• Replaces worn or warped rotors on Chevrolet Silverado 1500 HD and GMC Sierra 2500 HD
• Improves braking performance for heavy-duty vehicles like the Hummer H2 and Chevrolet Avalanche 2500
• Reduces brake fade during towing or heavy load conditions
• Minimizes rust and corrosion with zinc silver coating for extended rotor life
• Enhances braking consistency in wet or dusty environments

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 16.5 mm bolt hole diameter and 165.1 mm bolt circle diameter. Check rotor thickness before installation; replace if below the discard thickness of 26.5 mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures the 631-48039R rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and vented design contribute to long-term durability.
