DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a vented design. This combination enhances braking performance by improving heat dissipation and reducing brake fade, while the directional surface pattern helps channel gases and debris away from the contact area. The rust resistant coating and Geospec silver grey hat finish contribute to longer rotor life, making this product line suitable for demanding applications such as heavy-duty Chevrolet and GMC trucks and vans.

Detailed Product Description

This disc brake rotor is designed for compatibility with Chevrolet Avalanche 2500, Express 2500 and 3500, Savana 2500 and 3500, Sierra 2500, 2500 HD, 2500 HD Classic, 3500, 3500 HD, Silverado 2500, 2500 HD, 2500 HD Classic, 3500, 3500 HD, Suburban 2500, and Yukon XL 2500 models. The rotor features a 330 mm outside diameter and a 91.5 mm overall height, ensuring precise fitment. The vented rotor type improves airflow to reduce heat buildup during braking. The directional drilled and slotted surface enhances pad bite and helps maintain consistent braking performance by evacuating gases and debris. The rotor’s nominal thickness is 29 mm, with a discard thickness of 27 mm, providing clear service limits for safety. The rust resistant coating and Geospec silver grey hat finish protect against corrosion, extending the rotor’s service life in harsh environments.

Common Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling with vented design
• Improves braking response and pad bite with drilled and slotted surface
• Prevents corrosion and rust buildup for longer rotor lifespan
• Maintains consistent braking performance under high heat conditions
• Ensures proper fitment for Chevrolet and GMC 2500 and 3500 series trucks and vans

Installation Notes and Tips

Ensure the rotor is installed on compatible Chevrolet or GMC models listed in the fitment section. Verify the bolt hole pattern matches the vehicle’s hub (8 holes, 16.5 mm diameter). Check rotor thickness before installation; replace if below the discard thickness of 27 mm. Clean the rotor surface before mounting to remove any protective coatings or debris. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet or exceed OEM specifications for durability and performance.
