A worn disc brake rotor can show up as a pulsing pedal, grooves in the friction surface or a grinding noise. Worn pads or a sticking caliper can be behind these signs too, so find the cause before buying a rotor. Replace the pair together, one rotor on each side of the axle; this listing is a single rotor.
Fits
The vehicles it fits include the 2011-2025 Ram 2500, the 2009-2010 Dodge Ram 2500 and the 2011-2012 Ram 3500. It is a direct bolt-on replacement with weight and vane count that match the original equipment design, so no modifications are needed. If your vehicle is not named here, find it in the "Vehicles it fits" section.

Frequently Asked Questions
I'm doing brake pads and rotors on a 2011-2025 Ram 2500. Is the PowerStop AR8374SCR the right rear rotor?
Yes. The PowerStop AR8374SCR rear rotor fits the 2011-2025 Ram 2500, which takes one on each side of the axle. This listing is one rotor; brake pads are sold separately.
Does the PowerStop AR8374SCR work for 2009-2010 Dodge Ram 2500 brakes and rotors?
Yes. The PowerStop AR8374SCR also fits the 2009-2010 Dodge Ram 2500 and the 2011-2012 Ram 3500. If your vehicle is not named here, find it in the "Vehicles it fits" section.
Does the AR8374SCR come with PowerStop brake pads and rotors, or is it just one rotor?
No. This PowerStop AR8374SCR listing is one rear rotor only. Brake pads are sold separately, and the ABS tone ring is not included.
How does the cross-hatched face help PowerStop rotors and pads settle in?
The cross-hatched friction surface on this rotor is there for pad break-in. For the bedding steps, follow the instructions that come with the pads you install.
At what thickness is this rear rotor worn out?
Nominal thickness is 34.20 mm (1.35 in) and discard thickness is 32.40 mm (1.28 in). A rotor measuring 32.40 mm or less is due for replacement, so have it measured at a shop if you are unsure.
