Dynamite Friction 631-54280L Disc Brake Rotor - Rear Left

Overview of Dynamite Friction DFC Brake Rotor

The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver (part number 631-54280L) is engineered for reliable braking performance on select Ford and Lincoln vehicles. Designed with a directional, slotted and drilled surface, this rotor enhances heat dissipation and braking consistency for models like the Ford Explorer, Mustang, and Lincoln Nautilus.

• Directional slotted and drilled disc surface for improved heat management
• Nominal thickness of 12 mm with a discard thickness of 10.5 mm
• Rust-resistant zinc silver hat finish for extended durability
• 320 mm outside diameter with 5 bolt holes and 15.85 mm bolt hole diameter
• Center hole diameter of 71.06 mm and bolt circle diameter of 114.3 mm

Detailed Product Features and Specifications

This disc brake rotor features a plain disc finish combined with a zinc silver coated hat to resist corrosion and maintain structural integrity over time. The rotor’s 320 mm outside diameter and 27 mm height are designed to meet the exact specifications required for proper fitment on Ford Explorer, Mustang, and Lincoln Nautilus models. The directional slotted and drilled surface pattern helps reduce brake fade by allowing gases and debris to escape, improving overall braking response. With 5 bolt holes sized at 15.85 mm and a bolt circle diameter of 114.3 mm, this rotor ensures secure mounting and compatibility with the specified vehicles.

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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced cooling capabilities and corrosion resistance. This product line incorporates drilled holes and slots arranged directionally to optimize brake pad contact and heat dissipation. The silver zinc coating on the rotor hat adds a layer of rust protection, making it suitable for drivers seeking durability and consistent braking performance in daily driving conditions.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains proper thickness to ensure safe braking performance
• Compatible with Ford Explorer, Mustang, and Lincoln Nautilus models requiring 320 mm rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10.5 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5 bolt holes and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fitment and performance. The rust-resistant zinc silver coating and precise machining contribute to consistent braking and extended rotor life. While no specific warranty information is provided, the product is designed to comply with industry standards for disc brake rotors on Ford and Lincoln vehicles.
