Refresh your rear brakes with the Dynamic Friction brake kit 4212-42003, a bundled disc brake kit that pairs GEOSPEC-coated rotors with heavy-duty (HD) brake pads plus hardware for the rear axle in a single box. It drops in as a direct-fit replacement for the 2011-2025 Dodge Durango, 2011-2021 Jeep Grand Cherokee, and 2022 Jeep Grand Cherokee WK.
- GEOSPEC-coated rotors: the rotors come with Dynamic Friction's GEOSPEC coating.
- HD brake pads: heavy-duty brake pads for the rear axle.
- Hardware included: brake hardware comes in the kit.
Matched components arrive under one part number, so this 2011-2025 Dodge Durango brake kit — which also covers the listed 2011-2021 Jeep Grand Cherokee and 2022 Jeep Grand Cherokee WK applications — takes the guesswork out of ordering rear rotors, pads, and hardware separately. The rotors give the pads a fresh surface to clamp against, while the HD pads provide the friction for the rear brakes. Worn rotors and pads can show up as reduced braking, brake pulsation, noise, or vibration; if the rear brakes are the cause, this kit replaces them. For even, balanced stopping, it's best to service both rear corners together as a matched set.
