Dynamic Friction Company Disc Brake Rotor P/N:604-46041

Bring smooth, confident braking back to your rear axle with the Dynamic Friction brake rotor 604-46041, a DFC GEOSPEC coated blank (non-slotted, non-drilled) rotor built to replace the worn rear disc on the 2018-2020 Buick Regal Sportback and the 2016 Cadillac ELR. It is CNC-machined and mill-balanced to spin true for smoother stops during everyday driving. See the Buyer's Guide tab to confirm the engine and options for your vehicle.

• Precision-machined: CNC-machined to tight tolerances and 100% precision cut and mill-balanced for smoother stopping.
• OE vane configuration: matches the original vane configuration to support proper heat dissipation.
• Premium castings: engineered with G3000/G11H18 iron castings for strength, stability, and durability.
• GEOSPEC coating: provides corrosion protection superior to zinc or conventional painting, with a non-directional finish that promotes faster break-in.

The rotor arrives ready to install with no additional pre-degreasing preparation needed. For even, balanced braking, replacing both rear rotors as a matched set is recommended; this listing covers one rotor.
