Product Description

The DFC Geospec Rotors line is positioned for vehicle-specific brake service where correct fitment and consistent rotor replacement matter. Part number 4004-45025 covers front and rear disc brake rotor applications across multiple GM platforms, including the Chevrolet Equinox and GMC Terrain, along with several Buick models. If you are replacing worn rotors on a 2018-2020 Chevrolet Equinox or a 2018-2021 GMC Terrain, this rotor set matches the listed applications directly.

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

Common Problems This Part Addresses

• Brake pulsation from rotor wear or thickness variation
• Scoring or grooving on the braking surface
• Reduced braking consistency during normal stop-and-go driving
• Rotor replacement needs during brake pad service
• Front and rear brake maintenance on listed Chevrolet, GMC, and Buick vehicles

Installation Notes and Tips

Verify rotor size and axle position before installation. Compare the old rotor to the new part number 4004-45025 and confirm the vehicle year, make, model, and front/rear application against the fitment list. Brake system service should include inspection of pads, calipers, and hub surfaces so the new rotors seat correctly.

Quality Assurance

DFC Geospec Rotors are offered as a vehicle-specific brake component line from Dynamite Friction. Confirm fitment by VIN when possible, especially on 2017-2025 Chevrolet Equinox, GMC Terrain, and Buick applications, to ensure the correct rotor set is selected.
