PowerStop AR83074XPR Disc Brake Rotor Set - Front

PowerStop Drilled and Slotted Rotor Pair

PowerStop AR83074XPR is a drilled and slotted brake rotor pair built as a direct OE-fit upgrade for vehicles that need stronger heat management and consistent stopping performance. The vented rotor design, cross-drilled holes, and rounded slots help maintain a cleaner friction surface under demanding braking.

Compatible With select applications using a 15.40 in. outside diameter, 10-lug pattern, and 170 mm bolt circle, this rotor set is finished with silver zinc dichromate plating to help resist rust and corrosion. The Power Stop rotor line focuses on bolt-on replacement parts that install without special modifications.

Product Details

Power Stop drilled and slotted rotors are engineered for drivers who want a service replacement with added thermal control. The cross-drilled pattern helps move heat away from the braking surface, while the rounded slots sweep away gas, dust, and moisture to keep the pad contact area cleaner. This can support more consistent pedal feel during repeated stops and heavier braking conditions. The zinc dichromate finish adds a corrosion-resistant layer that helps the rotor maintain its appearance and surface protection over time. This part cross-references Centric Parts 120.67070 and Raybestos Brakes 780774 for the same application. Fits select 10-lug applications, including 2006-2011 Dodge Ram 2500 and 2006-2011 Dodge Ram 3500, front and rear where specified by the vehicle application. AR83074XPR is a practical choice for owners searching for a drilled and slotted brake rotor pair for Dodge Ram 2500 or Dodge Ram 3500 service replacement.

What It Can Help Address

• Brake fade during repeated stops
• Excess heat buildup in the rotor surface
• Rust and corrosion on exposed rotor surfaces
• Dust, gas, and moisture buildup between pad and rotor
• Uneven braking feel from worn or heat-affected rotors

Installation Notes and Tips

Verify rotor dimensions, bolt circle, lug count, and axle position before installation. This rotor set is a direct OE-fit replacement, so no special modifications are needed when used on the correct application. Inspect pads, calipers, and hub surfaces during service to confirm proper rotor seating and braking performance. For best results, follow the vehicle manufacturer’s brake service procedures and bedding recommendations.

Quality Assurance

PowerStop manufactures this rotor pair as part of its drilled and slotted brake rotor line, using a vented design and corrosion-resistant zinc plating for consistent service use. The AR83074XPR part number identifies the exact replacement specification for the listed applications.
