Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed to meet the braking demands of heavy-duty Ford trucks such as the Excursion, F-250 Super Duty, and F-350 Super Duty. This rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under heavy loads or extended use. The directional surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the rotor surface, improving braking consistency and performance.

Constructed with a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor ensures a long service life while maintaining safety standards. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance, complemented by a rust-resistant coating on the disc surface. The rotor’s dimensions include an outside diameter of 326 mm and an overall height of 98.5 mm, with eight bolt holes sized at 16.1 mm diameter on a 170 mm bolt circle, matching the factory specifications for the specified Ford models.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The drilled and slotted pattern is directional, optimized to improve braking performance by facilitating better heat dissipation and debris removal. This product line is suitable for heavy-duty applications where consistent braking performance and rotor longevity are critical.

Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling
• Improves braking performance in wet or dusty conditions
• Minimizes rotor surface corrosion with rust-resistant coating
• Maintains consistent brake pad contact with slotted and drilled surface
• Compatible with Ford Excursion, F-250 Super Duty, and F-350 Super Duty models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the vehicle’s hub using the 170 mm bolt circle diameter and 16.1 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 830-54161L rotor to meet OEM standards for fitment and performance. The rust-resistant coating and Geospec silver grey hat finish contribute to extended rotor life. While no specific warranty information is provided, the product is designed for durability and consistent braking performance on compatible Ford models.
