PowerStop AR85138XPR Disc Brake Rotor Set - Front

Overview

Power Stop AR85138XPR is a drilled and slotted disc brake rotor set built as a direct OE-fit upgrade for heavy-duty braking applications. It combines cross-drilled cooling paths with rounded slots to help maintain a cleaner friction surface under heat, dust, and moisture.

Compatible with Ford F-250 Super Duty and Ford F-350 Super Duty front brake applications, this rotor set is engineered for straightforward replacement without special modifications.

Key Features

• Slotted X drilled surface helps move gases, dust, and moisture away from the rotor face.
• Vented rotor construction supports heat management during demanding stops.
• Silver zinc dichromate plating helps resist rust and corrosion.
• Direct OE fit simplifies replacement on supported applications.
• Part number AR85138XPR for easy identification and ordering.

Detailed Description

Power Stop AR85138XPR is a front disc brake rotor set with a 13.70-inch outside diameter, 8-lug bolt pattern, and vented construction. The drilled and slotted design is intended to improve cooling and maintain consistent pad contact by clearing surface contaminants from the braking area. For buyers searching for a Ford F-250 Super Duty front brake rotor or Ford F-350 Super Duty front brake rotor, this part provides an OE-style replacement with performance-focused surface machining. The AR85138XPR also cross-references Centric Parts 120.65121 and Raybestos Brakes 680640 for the same application.

Power Stop’s drilled and slotted rotor line focuses on bolt-on replacement parts that combine OE fitment with surface features aimed at heat control and surface cleaning. The AR85138XPR follows that approach with corrosion-resistant plating and a direct-fit design for supported Ford truck applications.

What It Helps Address

• Brake fade during repeated or high-load stops.
• Rotor surface buildup from dust, gas, and moisture.
• Corrosion on exposed rotor surfaces.
• Fitment issues caused by non-OE dimensions.
• Uneven braking feel from worn or heat-affected rotors.

Installation Notes

Fits 2006-2007 Ford F-250 Super Duty, front, from 12/18/06. Fits 2008-2012 Ford F-250 Super Duty, front. Fits 2008-2012 Ford F-350 Super Duty, front, SRW disc brake rotor. Verify rotor dimensions, bolt circle diameter, and hub fitment before installation. Part number AR85138XPR should be matched to the vehicle’s front brake application before service.

Quality Assurance

Power Stop designs this rotor set as a direct OE-fit replacement with drilled and slotted machining, vented construction, and zinc dichromate plating for corrosion resistance. Part number AR85138XPR is built for supported Ford Super Duty brake applications.
