Product Details

DFC GEOSPEC rotors are machined to tight tolerances, then finished and inspected to meet critical OE dimensions. The coated surface is designed to reduce corrosion on exposed rotor areas while the friction surface is cleaned away during normal braking. The included DFC 5000 Advanced pads are formulated for stable friction performance and reduced initial break-in, making this kit a practical choice for rear brake service on Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, and GMC Savana 3500 applications. This part number, 4502-48099, is built for drivers and fleets that need consistent rear braking performance and a clean, service-ready rotor finish.

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

What It Helps Address

• Rear brake noise during stopping
• Rotor rust on exposed braking surfaces
• Uneven pad bedding after brake service
• Reduced braking consistency from worn rear components
