Product Details

The DFC GEOSPEC rotor line is engineered to match OE specifications for durability, stability, and reliable fitment. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry-ready packaging saves time during brake service. The 5000 Advanced pad formulation is developed for consistent friction performance and uses premium shims to support quieter operation. This part number, 4502-68028, is a practical rear brake solution for Nissan Armada and INFINITI QX80 owners looking for a complete rotor-and-pad service kit.

Common Brake Issues This Kit Addresses

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or uneven pad transfer
• Rust buildup on exposed rotor surfaces
• Reduced stopping performance from worn friction material
• Longer service time caused by rotors that require cleaning before install

Installation Notes

Rear axle installation should follow factory service procedures, including proper cleaning of hub mating surfaces and verification of rotor runout after installation. The rotor coating is removed naturally by the brake pads during normal use. Confirm rear fitment by year, make, and model before ordering; this kit is for rear applications only.

Quality Assurance

Each rotor is machined to tight tolerances, inspected for critical dimensions, and checked for balance where applicable. DFC states that these rotors carry a 12-month warranty against defects in material and workmanship. Part number 4502-68028 is built to OE-style standards for rear brake service on the listed Armada, QX80, and QX56 applications.
