Dynamic Friction 830-54279L Disc Brake Rotor - Front Left

Front Left Drilled and Slotted Rotor for Explorer and Aviator

The Dynamic Friction DFC Geoperformance Rotor - Drilled and Slotted, part number 830-54279L, is a front left disc brake rotor built for specific Ford and Lincoln applications. It features a vented, directional braking surface with drilled and slotted machining for consistent pad contact and heat management.

Compatible with 2020-2026 Ford Explorer front left and 2020-2025 Lincoln Aviator front left, this rotor uses a 345 mm outside diameter, 5-lug pattern, and a 114.3 mm bolt circle for the listed applications. The Geospec Silver Grey hat finish and rust resistant coating add corrosion protection in service.

DFC Geoperformance Rotor Line

The DFC Geoperformance Rotor line focuses on application-specific brake rotors with drilled and slotted surfaces, vented construction, and directional brake faces. This part number 830-54279L follows that format for the front left position on the Ford Explorer and Lincoln Aviator platforms.

Detailed Description

Use this Dynamic Friction rotor when replacing the front left brake rotor on a Ford Explorer or Lincoln Aviator with the listed brake configuration. The drilled and slotted face is machined to maintain pad bite and support more even rotor surface contact, while the vented design helps move air through the rotor body during braking.

The 30.5 mm discard thickness and 32 mm nominal thickness provide the dimensional reference needed for service planning, and the 71.03 mm center hole diameter supports the specified hub fitment. If you are searching for a Ford Explorer front left drilled and slotted rotor or a Lincoln Aviator 345 mm front disc brake rotor, part number 830-54279L matches the listed applications.

Common Brake Issues This Rotor Can Address

• Brake pulsation from a worn or uneven front rotor surface
• Reduced braking consistency from heat buildup in the rotor face
• Surface corrosion on the braking area or hat section
• Noise or vibration associated with rotor wear
• Need for a direct replacement front left rotor for the listed Ford and Lincoln models

Installation Notes and Tips

Verify rotor diameter, bolt pattern, center hole diameter, and front left position before installation. Confirm the vehicle uses the listed 345 mm front disc specification for the Ford Explorer or Lincoln Aviator application. Clean the hub mounting surface before installing the rotor, and inspect pads, caliper hardware, and wheel bearings for wear at the same time.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
