Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a complete brake service solution for front axle applications. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected to meet OE specifications. The pads are formulated for consistent friction performance and assembled with shims that help reduce noise, vibration, and harshness. Part number 4502-48132 is a practical choice for drivers servicing older Jeep J20 and Chevrolet K20 or GMC K2500 front brake systems.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes

These components are intended for front axle brake service. Verify rotor and pad application against the vehicle’s brake configuration, including rear drum size, brake package codes, and axle details listed in the fitment notes before installation. Clean the hub mounting surface, inspect calipers and hardware for wear, and follow proper bedding procedures after installation to help the pads and rotors seat evenly.

Quality Assurance

Each DFC GEOSPEC rotor is 100% inspected for critical dimensions and OE-spec compliance, with vented rotors also checked for balance and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship.
