Detailed description

Power Stop AR85203XPR rotors are designed for drivers who want a replacement rotor with added cooling and surface cleaning features. The slotted X drilled design supports more stable contact between the pad and rotor, while the zinc-plated finish helps protect the rotor surface from corrosion. This part cross-references Monroe Shocks & Struts (e.g., L1MZ 2C026-B) for the same application. Compatible with Ford Explorer rear brake service from 2020-2026 and Ford Mustang rear brake service from 2024-2025, this rotor set follows OE fitment dimensions for a direct replacement.

What it is used for

• Replacing worn rear brake rotors with an OE-style direct fit part.
• Reducing surface rust on exposed rotor areas.
• Improving heat dissipation during repeated braking.
• Helping clear dust, gas, and moisture from the rotor face.
• Restoring braking feel when rotor wear or scoring is present.

Installation notes and tips

Install on the rear position only and verify rotor dimensions before service. The direct OE fit means no special modifications are needed. Confirm application details for Ford Explorer and Ford Mustang models, including the 2022 Explorer note excluding red painted calipers.
