Shopping for a Dodge Durango brake rotor? The Dynamic Friction Company Disc Brake Rotor 900-40124 is a rear replacement rotor for the 2021-2025 Dodge Durango, machined to help deliver smooth, even braking on the rear axle.

  • Precision mill-balanced: 100% mill-balanced for smoother stopping and reduced vibration at any speed.
  • Premium iron castings: engineered with G3000/G11H18 iron castings for strength, stability, and durability.
  • Geomet® coated: provides high-performance corrosion protection.
  • OE vane configuration: a vented design matched to original equipment to support proper heat dissipation.

A fine-turned finish (16 RMS) helps with initial rotor and pad break-in, while tight tolerances — disc thickness variation held to .010 mm maximum and lateral runout to .050 mm maximum — support quiet, consistent braking. This high-carbon disc brake rotor is Geomet® coated for corrosion protection. Because rotors wear together, replacing both rear rotors as a matched pair is recommended for even, balanced braking; this listing is for one rotor sold individually.
