Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor construction that supports stable braking performance and corrosion resistance. On this rotor, the plain disc finish is paired with a zinc silver hat finish and a rust resistant coating, while the slotted X drilled surface helps maintain pad bite and manage surface buildup during repeated stops. The 90 mm center hole diameter, 15.5 mm bolt hole diameter, and 16 mm stud/lug hole diameter align with the listed Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Mark LT front right fitments. This part number 631-54204R is a direct fit for the specified applications and is listed for 2007-2021 Lincoln Navigator and related Ford truck platforms.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from heat buildup during repeated stops
• Surface corrosion on exposed rotor and hat areas
• Pad glazing or uneven pad contact on a worn front rotor
• Noise and vibration associated with rotor wear

Installation Notes and Tips

Install only on the front right position listed in the fitment data. Confirm the rotor is matched to the vehicle’s 6-lug, 135 mm bolt circle configuration before installation. The directional brake surface requires correct orientation during mounting. For 2015-2020 Ford F-150 applications, the fitment notes list both manual parking brake applicable and electric parking brake compatible configurations; verify the vehicle’s brake setup before ordering. For 2010-2014 Ford F-150 applications, the fitment notes specify 6 lug wheels and compatibility with drum brake hardware kits. Always inspect pads, caliper condition, and hub surfaces before installing a new rotor.

Quality Assurance

Dynamite Friction supplies brake components for direct replacement use, and this rotor is built with a rust resistant coating and zinc silver hat finish to support long-term appearance and service life in exposed brake environments.
