Product Details

DFC’s GEOSPEC rotor line is built for drivers who want corrosion protection and OE-level fit and finish in a brake service kit. The coated surface helps resist rust better than conventional paint or zinc-style coatings, while the dry packaging saves prep time during installation. The rotors are machined to tight tolerances and finished for consistent contact with the pad surface.

The included DFC 5000 Advanced Brake Pads are formulated for stable braking performance and reduced break-in time. This brake kit is a practical choice for rear brake replacement on the Dodge Durango and Jeep Grand Cherokee, especially when you want a complete rotor-and-pad solution under one part number, 4502-42055.

Used For

• Rear brake rotor and pad replacement
• Brake noise caused by worn pads or uneven rotor surfaces
• Rust buildup on exposed rotor hats and edges
