DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface features such as drilled holes and slots to improve braking efficiency and reduce heat buildup. This product line is tailored for vehicles requiring directional rotors that maintain consistent performance and durability. The 830-42004L rotor exemplifies these characteristics with its solid construction and rust-resistant coating, making it suitable for both daily driving and moderate performance applications.

Detailed Product Description

This Dynamite Friction disc brake rotor features a solid design with a 330 mm outside diameter and a nominal thickness of 14 mm, ensuring structural integrity and longevity. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance alongside the rust-resistant coating applied to the entire rotor. With 5 bolt holes sized at 17 mm diameter and a bolt circle diameter of 127 mm, this rotor is engineered for precise fitment on compatible Dodge and Jeep models.

Applications and Problem Solving

• Improves braking performance on Dodge Durango and Jeep Grand Cherokee vehicles
• Reduces brake fade during extended or aggressive braking
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes rust and corrosion for longer rotor life
• Enhances pad bite and braking consistency in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor is installed on vehicles with matching bolt pattern and dimensions, specifically Dodge Durango and Jeep Grand Cherokee models. Verify the rotor thickness before installation; the nominal thickness is 14 mm with a discard thickness of 12.5 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor distortion. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet industry standards for durability and performance. The rust-resistant coating and Geospec silver grey hat finish contribute to corrosion protection, extending rotor service life. While no specific warranty information is provided, Dynamite Friction products are manufactured to maintain consistent braking performance on compatible Dodge and Jeep vehicles.
