Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built around matched braking components for service work on the rear axle. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions. The pads are formulated for consistent friction and assembled with NVH-focused shims to support smooth, quiet braking on Jeep Wrangler JK rear brake jobs.

This part number 4502-42083 is a practical choice for drivers servicing a 2012-2017 Jeep Wrangler rear disc brake rotor setup, a 2018 Jeep Wrangler JK rear brake replacement, or a 2007-2011 Jeep Wrangler rear brake kit. It is also listed for 2018 Jeep Wrangler rear applications with standard brakes or heavy duty brakes, depending on front rotor configuration noted in the fitment data.

What It Helps Address

• Rear rotor rust and surface corrosion
• Brake noise during stops
• Uneven pad bedding after brake service
• Reduced braking consistency from worn rear components
• Time spent sourcing separate rotors and pads

Installation Notes

Each rotor is processed dry and ready to install, which eliminates the need to clean off oil before assembly. Follow the vehicle-specific service procedure for rear brake replacement, inspect related wear items, and verify proper pad seating during the initial break-in period. Confirm the correct rear application for your Jeep Wrangler or Wrangler JK before ordering, especially on 2018 models with standard or heavy duty brake configurations.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, inspected for balance and critical dimensions, and backed by a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured and scorched to support stable friction performance from the first stop.
