Product Description

The PowerStop AR85155XL is an Evolution Drilled & Slotted rear left rotor engineered for the 2013-2022 Ford F-250 and F-350 Super Duty equipped with Single Rear Wheels (SRW). At 14.30" diameter with an 8x170mm bolt pattern and 1.500" nominal thickness, it matches OEM dimensions exactly for a direct bolt-on installation with no caliper bracket modifications required. The cross-drilled and slotted design combines the cooling benefits of drilled holes -- which can keep rotor temperatures up to 180°F lower than solid blanks -- with the debris-clearing function of rounded slots that maintain a clean friction contact patch between pad and rotor surface during every stop. PowerStop sources only G3000 grade iron castings from premium foundries for the Evolution line, then precision machines each rotor to strict Disc Thickness Variation (DTV) and runout tolerances for smooth, vibration-free braking. Silver zinc dichromate plating on all non-friction surfaces provides corrosion resistance to extend the service life of the rotor between pad changes. The Evolution Drilled & Slotted is PowerStop's most popular performance rotor for street and light track applications, balancing improved braking performance with daily drivability. Important: this rotor is for Single Rear Wheel Super Duty configurations only -- it does not fit Dual Rear Wheel (DRW) models, which use a different bolt pattern and rotor diameter. This is the left (driver side) rotor only; the right (passenger side) is AR85155XR, sold separately. Rotors should always be replaced in pairs. Backed by PowerStop's 90-day / 3,000-mile warranty on individual components.
