  • Directional drilled and slotted vented rotor surface
  • Nominal thickness of 38 mm with discard thickness at 36 mm
  • Rust resistant coating for extended rotor life
  • Geospec silver grey hat finish for corrosion protection
  • Eight bolt holes with 16.2 mm diameter and 170 mm bolt circle diameter
  • Overall rotor diameter of 331 mm and height of 99.5 mm

Product Line Details: DFC Geoperformance Rotor - Drilled and Slotted

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide enhanced braking performance through improved heat dissipation and debris removal. The drilled and slotted surface reduces brake fade under heavy use, while the vented rotor design helps maintain optimal operating temperatures. This product line is tailored for heavy-duty applications, making it suitable for Ford Super Duty trucks and Excursion models requiring reliable stopping power.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 38 mm and a discard thickness of 36 mm, ensuring a long service life before replacement is necessary. The rotor is vented to improve airflow and cooling during braking. The directional surface type, with both drilled holes and slots, aids in water and gas evacuation, reducing brake fade and maintaining consistent performance. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance, complemented by an overall rust-resistant coating on the rotor surface. The rotor measures 331 mm in outside diameter and 99.5 mm in height, with eight bolt holes sized at 16.2 mm diameter on a 170 mm bolt circle diameter, matching the stud/lug hole pattern for secure fitment.

Applications and Problem Solving

  • Improves braking performance on Ford Excursion and Super Duty trucks
  • Reduces brake fade during heavy towing or hauling
  • Enhances heat dissipation to prevent rotor warping
  • Minimizes rust and corrosion for longer rotor life
  • Maintains consistent braking under wet or harsh conditions

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 36 mm. The directional drilled and slotted surface requires correct orientation during installation to maintain optimal performance. Verify bolt hole alignment with the 170 mm bolt circle diameter and 16.2 mm bolt hole diameter for proper fitment on Ford Excursion, F-250 Super Duty, and F-350 Super Duty models. Clean the rotor surface before installation to remove any protective coatings or residues.

Quality Assurance

Dynamite Friction manufactures the 830-54174L rotor to meet strict quality standards, including rust-resistant coatings and precise machining tolerances. While specific warranty details are not provided, the rotor is designed to meet OEM specifications for Ford heavy-duty trucks, ensuring reliable and consistent braking performance.
