Product Description

This DFC rotor is built around the core dimensions and mounting pattern needed for the listed Ford Ranger, Ford Explorer, Ford Bronco II, Mazda B3000, Mazda B4000, and Mazda Navajo front right brake applications. The vented design helps manage heat, while the drilled and slotted braking surface supports consistent pad contact and a cleaner rotor face during service. The zinc silver hat finish and rust resistant coating add corrosion protection where the rotor is exposed to the elements.

For shoppers searching for a 1990-1994 Ford Ranger front right drilled and slotted brake rotor, or a 1991-1992 Ford Explorer front right vented rotor, part number 631-54119R provides a direct match to the listed configurations. It is also a fitment-specific option for Mazda B3000, Mazda B4000, and Mazda Navajo front right brake service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Replacing a worn front right rotor with measured discard thickness near service limits
• Restoring braking performance on Ford Ranger, Ford Explorer, or Ford Bronco II front axle setups
• Addressing rotor surface wear, scoring, or uneven pad contact
• Servicing Mazda B3000, Mazda B4000, or Mazda Navajo front brake systems with the listed fitment
• Updating a vented rotor with drilled and slotted surface geometry

Installation Notes

Verify rotor diameter, bolt circle, lug count, and front right application before installation. Confirm the vehicle’s rear drum size and front axle configuration against the fitment notes, especially on Ford Ranger and Ford Explorer models. Clean the hub mounting surface before installing the rotor, and inspect pads, caliper hardware, and bearings for wear during brake service. Part number 631-54119R is directional, so install it in the correct orientation for the front right position.

Quality Assurance

Dynamite Friction DFC brake rotors are specified with defined thickness, finish, and corrosion protection details to support accurate parts selection and repeatable brake service. The silver zinc hat finish and rust resistant coating help maintain rotor appearance and surface protection in normal use.
