Bring smooth, vibration-free stops to your van's rear brakes with the Dynamic Friction Company Disc Brake Rotor 604-40115 — a DYNAMIC FRICTION brake rotor built as a direct-fit rear replacement for the 2014-2021 RAM ProMaster 1500, 2500, and 3500. This DFC GEOSPEC coated rotor is a blank (non-slotted, non-drilled) casting designed to meet the same form, fit, and function as OEM brake rotors, so it installs in the factory location without modification.

  • GEOSPEC coating: provides superior corrosion protection over zinc and conventional painting.
  • Premium iron castings: engineered with G3000/G11H18 iron for strength and stability.
  • Precision machined: CNC-machined to tight tolerances, then 100% precision cut and mill-balanced for smoother stopping and reduced vibration.
  • OE vane configuration: carries the original-equipment vane configuration to support proper heat dissipation.
  • Ready to install: non-directional finish promotes faster break-in, and no additional pre-degreasing is needed.

Because rotors wear as a set, replacing both rear rotors together as a matched pair helps keep braking even and balanced. This listing covers the rear position for the 2014-2021 RAM ProMaster 1500, 2500, and 3500 — see the Buyer's Guide tab for full engine-level fitment.

Frequently Asked Questions

What vehicles does the DYNAMIC FRICTION brake rotor 604-40115 fit?

It is a direct-fit rear replacement for the 2014-2021 RAM ProMaster 1500, 2500, and 3500. Check the Buyer's Guide tab to confirm the engine-level fit for your van.

Is this a blank disc brake rotor?

Yes. It is a blank rotor with a smooth, non-slotted and non-drilled braking surface, finished with a non-directional pattern to promote faster break-in.

What is the GEOSPEC coating?

GEOSPEC is DFC's rotor coating that provides superior corrosion protection over zinc and conventional painting, helping the casting resist rust.

Do I need to clean or degrease the rotor before installing it?

No. It ships ready to install with no additional pre-degreasing preparation needed, which saves time during installation.

Should I replace both rear rotors at the same time?

It's recommended. Rotors are sold individually, but replacing both rear rotors as a matched pair helps keep braking even and balanced from side to side.
