• Overall diameter of 308 mm and height of 47.1 mm

Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed to meet the braking demands of full-size SUVs like the Ford Expedition and Lincoln Navigator. Its vented rotor construction allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving pad contact and reducing the risk of brake fade.

The rotor features a plain disc finish combined with a zinc silver coating on the hat to resist rust and corrosion, extending the rotor’s service life. With a nominal thickness of 30.1 mm and a discard thickness of 27.7 mm, this rotor provides a solid balance between durability and performance. The 5-bolt hole pattern with a 135 mm bolt circle diameter ensures proper fitment and secure mounting on compatible vehicles.

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

The DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This design is intended to improve braking efficiency and rotor longevity, particularly for vehicles that require reliable stopping power under demanding conditions. The silver zinc coating on the rotor hat enhances rust resistance, making it suitable for environments prone to moisture and road salt exposure.

Common Applications and Problem Solving

• Reduces brake fade during towing or heavy braking situations
• Improves braking response in wet or humid conditions
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes brake dust accumulation on rotor surface
• Protects against corrosion to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford Expedition or Lincoln Navigator models matching the 5-lug, 135 mm bolt circle pattern. Verify rotor thickness before installation; replace if below the discard thickness of 27.7 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed for lug nuts to avoid rotor distortion.

Quality Assurance

Dynamite Friction manufactures the 631-54176L rotor to meet industry standards for durability and performance. The rust-resistant zinc silver finish on the rotor hat helps maintain structural integrity over time. While specific warranty details are not provided, Dynamite Friction products are generally designed to comply with OEM quality requirements for Ford and Lincoln vehicles.
