Dynamic Friction Company Disc Brake Rotor P/N:600-40127
Dynamic Friction 604-40127 rear brake rotor for the 2019-2026 Ram 3500 is the machined surface the pads clamp against to slow the wheel. This Dynamic Friction brake rotor is a DFC GEOSPEC coated rotor.
A pulsing brake pedal, deep grooves on the face of the disc brake rotor, or a thickness at or below the discard spec can mean the rotor is worn. Pulsation alone does not prove the rotor is the problem, since worn pads can cause it too.
This rotor fits the 2019-2026 Ram 3500 and is designed to meet the same form, fit and function as OEM brake rotors. The 2019-2026 Ram 3500 takes two. This listing is one rotor for the rear axle; the other side of that axle is normally replaced at the same time.
