Refresh the rear brakes on your Jeep Grand Cherokee with the Dynamic Friction GEOSPEC Coated Brake Rotor (P/N 604-42045). This rear rotor is engineered to meet the same form, fit, and function as the OEM rotor, dropping into the factory location on the 2024-2025 Dodge Charger Daytona, 2022-2025 Jeep Grand Cherokee, and 2021-2025 Jeep Grand Cherokee L — see the Buyer's Guide tab for engine-level applications.

  • GEOSPEC coating: provides superior corrosion protection over zinc and conventional painting.
  • CNC-machined: cut to tight tolerances and 100% precision-cut, mill-balanced for smoother, vibration-reduced stops.
  • OE vane configuration: follows the original equipment vane layout to support proper heat dissipation.
  • Premium castings: made with G3000/G11H18 iron castings for strength, stability, and durability.
  • Non-directional finish: promotes faster break-in and smoother stops, and it's ready to install with no pre-degreasing needed.

Rotors wear as a pair, so replacing both rear rotors together as a matched set is recommended for even, balanced braking. This listing is for one rotor; order two for a complete rear-axle replacement. Diagnose the cause of pulsation, noise, or vibration before replacing, since those signs may have other sources.
