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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on delivering rotors with enhanced heat management and corrosion resistance. Featuring a vented design combined with a drilled and slotted surface, these rotors help maintain consistent braking performance under demanding conditions. The zinc silver hat finish and rust-resistant coating extend rotor life, making them suitable for heavy-duty applications on Chevrolet and GMC trucks.

Detailed Product Description

This disc brake rotor is constructed with a vented design to improve airflow and reduce heat buildup during braking. The directional surface features both drilled holes and slots, which aid in dissipating heat, reducing brake fade, and helping to evacuate water and debris from the rotor surface. The rotor’s nominal thickness is 29.1 mm, with a discard thickness of 26.5 mm, ensuring a solid lifespan before replacement is necessary. The zinc silver finish on the hat and rust-resistant coating protect against corrosion, which is critical for vehicles exposed to harsh environments. With eight bolt holes sized at 16.5 mm and a bolt circle diameter of 165.1 mm, this rotor fits securely on compatible Chevrolet and GMC heavy-duty trucks.

Applications and Problem Solving

• Restores braking efficiency on Chevrolet Silverado 1500 HD and GMC Sierra 1500 HD
• Reduces brake fade during heavy towing or hauling with vented rotor design
• Improves heat dissipation and water evacuation with drilled and slotted surface
• Prevents rust and corrosion in harsh weather conditions with protective coatings
• Ensures proper fitment and secure mounting with precise bolt hole specifications

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the bolt hole pattern and center hole diameter match your vehicle’s hub specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 26.5 mm.

Quality Assurance

Dynamite Friction manufactures the 631-48048R rotor to meet or exceed OEM specifications for Chevrolet and GMC heavy-duty trucks. The rust-resistant coating and zinc silver hat finish contribute to long-term durability.
