Replace worn Ram 1500 rotors with the Dynamic Friction Company GEOSPEC Coated Disc Brake Rotor 604-40121 (also written 60440121), a rear-axle direct-fit replacement for the 2019-2026 RAM 1500. This blank rotor runs a smooth, non-slotted braking face and ships coated and ready to install.
Built to meet the same form, fit, and function as the OEM rotor for the listed RAM 1500 application, this rotor installs on the rear axle. Because the pair wears together, replacing both rear rotors at the same time is recommended for even, balanced braking. Signs a rotor may need replacing include pulsation through the pedal, vibration under braking, scoring, or grooving on the friction surface. See the Buyer's Guide tab to confirm the engine and fitment for your vehicle.
