Product Details

Power Stop’s rear drilled, slotted, and zinc plated rotor line focuses on cooling, surface cleaning, and corrosion resistance. The cross-drilled holes help move heat away from the braking surface, while the rounded slots sweep away gas, dust, and moisture to maintain consistent pad-to-rotor contact. On the Ford F-350 Super Duty, rear rotor replacement with AR85118XPR provides an OE-style fit for straightforward service.

This part cross-references Raybestos Brakes 680344 for the same application.

What This Rotor Set Helps Address

• Brake fade during repeated stops or heavy-duty driving
• Surface rust on exposed rotor faces
• Dust and moisture buildup on the braking surface
• Uneven pad contact caused by worn rear rotors
• Reduced braking consistency from heat retention

Installation Notes

Compatible With 2005-2012 Ford F-350 Super Duty rear DRW applications. Verify rotor dimensions, bolt circle diameter, and hub fitment before installation.
