Product Details

DFC built this brake kit for drivers who want a complete rear brake service with matched components. The GEOSPEC rotors are cast to G3000/G11H18 specifications, machined to tight tolerances, and inspected for balance and critical dimensions. The 5000 Advanced pads are formulated for consistent friction, with surface conditioning that helps reduce initial break-in time. Part number 4502-42050 is a practical choice for rear brake replacement on Jeep Grand Cherokee and Dodge Durango models where OE-style fit and finish matter.

Compatible fitment includes 2021-2022 Dodge Durango, rear; 2022 Jeep Grand Cherokee WK, rear with vented rear disc; 2021 Jeep Grand Cherokee, rear with vented rear disc and 350mm front rotors; 2011-2020 Dodge Durango, rear; 2014-2020 Jeep Grand Cherokee, rear except heavy duty brakes; 2014-2020 Jeep Grand Cherokee, rear heavy duty brakes; 2018 Jeep Grand Cherokee, rear except heavy duty brakes; and 2011-2013 Jeep Grand Cherokee, rear with 350mm front rotors and vented rear rotors.

Common Brake Issues This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Squealing or noise from aged pad friction material
• Reduced stopping performance from thin or heat-affected components
• Rust buildup on exposed rotor surfaces
• Uneven brake feel during rear axle service

Installation Notes

Install on the rear axle only and verify rotor and pad configuration against the vehicle’s brake package before service. The rotors are shipped dry and ready to install, which helps reduce prep time during brake work. For best results, follow the vehicle manufacturer’s brake service procedure and complete a proper pad bed-in after installation.

Quality Assurance

Each DFC GEOSPEC rotor is inspected for critical dimensions and balance, and every rotor carries a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured, scorched, and assembled with premium shims to support stable braking performance and improved NVH control.
