Product Details

DFC’s GEOSPEC rotor line is built for drivers who want a direct-fit rear brake solution with added corrosion protection. The coated finish helps resist rust better than conventional paint or zinc coatings, while the dry shipping process eliminates the need to clean oil from the rotor before installation. The rotors are machined to tight tolerances, balanced where required, and inspected to confirm critical dimensions meet OE specifications.

The 5000 Advanced ceramic pads are formulated for stable friction performance and quieter operation. DFC uses post-curing and scorching to help reduce the need for extended break-in and to support consistent stopping response from the first stop. The included hardware kit addresses worn or corroded brake hardware that can contribute to noise, uneven wear, and caliper movement.

This part number, 4512-68028, is a rear brake kit for Infiniti QX56, Infiniti QX80, and Nissan Armada rear axle service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Rear brake noise during stops
• Rust buildup on rotor surfaces
• Uneven or premature pad wear
• Brake pulsation from worn rotors
• Loose or fatigued brake hardware

Installation Notes

Install as a rear axle service kit on the listed Infiniti and Nissan applications. The rotors are shipped dry and ready for installation, so no oil removal is required before mounting. Clean the hub surface, verify caliper hardware condition, and follow the vehicle manufacturer’s torque and bedding procedures after installation.

Quality Assurance

DFC states that each rotor is inspected for critical attributes and built to meet OE specifications. The rotors include a 12-month warranty against defects in material and workmanship.
