Product Details

Power Stop’s rear drilled and slotted rotor line focuses on brake cooling and consistent friction contact under load. The cross-drilled holes help dissipate heat, while the rounded slots clear surface contaminants to maintain a cleaner pad-to-rotor interface. For Ram ProMaster owners looking for a rear rotor replacement with OE-style fitment and added surface treatment, PowerStop AR8394XPR provides a practical upgrade path. This part cross-references Raybestos Brakes 781109 for the same application.

Common Problems This Rotor Can Address

  • Brake fade during repeated stops or heavier-duty use
  • Surface rust and corrosion on exposed rotor faces
  • Dust, gas, and moisture buildup between pad and rotor
  • Uneven braking feel caused by worn rear rotors
  • Reduced cooling performance from standard replacement rotors

Installation Notes and Tips

Verify rear axle fitment before ordering and match the rotor dimensions to the existing brake setup on your Ram ProMaster 1500, 2500, or 3500. The direct OE fit means no special modifications are needed, but rotor replacement should be paired with a full brake inspection, including pads, caliper operation, and hub condition. Clean the hub mounting surface before installation to help prevent runout and uneven wear.

Quality Assurance

PowerStop manufactures this rotor with a zinc dichromate coating for corrosion resistance and a direct-fit design for OE-style replacement. Part number AR8394XPR is built to meet the listed fitment for 2014-2021 Ram ProMaster rear applications.
