This kit combines corrosion-resistant rotor coating with low-dust ceramic friction material for consistent braking performance, quieter operation, and reduced brake fade. The 4302-39017 is a practical choice for drivers looking for a complete rear brake service solution for Chrysler 300 and Dodge Charger platforms.

Key Features

• Rear disc brake kit with coated rotors and ceramic pads
• GEOSPEC rotor coating helps resist rust and keeps the rotor ready to install
• 3000 series ceramic pads are formulated for stable friction and low dust
• Post-cured and scorched pad construction supports consistent initial performance
• Rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Rotor machining and non-directional finish support even pad bed-in
• Part number 4302-39017 for fitment-based ordering and service lookup

Product Details

Dynamic Friction’s GEOSPEC rotor line uses a durable silver-gray coating to improve corrosion resistance compared with conventional painted or zinc-coated rotors. The rotors are processed dry and shipped dry, which eliminates the need to clean off oil before installation. The 3000 ceramic pad formulation is designed for passenger vehicles and light-duty trucks, with stable friction across a wide temperature range and reduced dust output. Together, these components create a service kit intended to restore rear braking performance with OE-style fit and finish characteristics. The 4302-39017 is also referenced as part of the DFC GEOSPEC Rotors with 3000 Ceramic Brake Pads line.

Common Issues This Kit Addresses

• Rear brake noise, vibration, or harshness
• Reduced stopping performance from worn pads and rotors
• Brake dust buildup on wheels
• Rotor surface rust and corrosion
• Uneven pad bedding after brake service

Installation Notes

Compatible With rear brake service applications only. Fitment includes 2005-2022 Chrysler 300 rear, 2005-2021 Dodge Charger rear, 2005-2020 Dodge Challenger rear, and 2005-2008 Dodge Magnum rear, with notes for certain Brembo, Police, Daytona, and vented rotor configurations. Verify the exact rear brake setup before ordering, since some listings exclude specific packages or caliper types. Part number 4302-39017 should be matched to the vehicle’s rear brake configuration and notes shown in the fitment table.

Quality Assurance

DFC rotors are machined to tight tolerances, inspected for balance where applicable, and checked against critical specifications before release. The rotors carry a 12-month warranty against defects in material and workmanship. The 4302-39017 reflects Dynamic Friction’s OE-specification approach for durability, reliability, and stable braking performance.
