ACDelco 18A80724XS Specialty Performance Rear Disc Brake Rotor

The ACDelco 18A80724XS is an ACDelco Specialty Performance rear disc brake rotor engineered to deliver enhanced stopping power and thermal management over standard smooth-faced rotors. Designed as a high-quality replacement component, this rotor features a cross-drilled and slotted surface that promotes rapid heat dissipation, reduces brake fade under repeated or heavy stopping, and helps expel gases and debris from the pad-to-rotor interface for consistently firm pedal feel.

Key Features:

• Cross-Drilled & Slotted Design — Improves heat dissipation, reduces brake fade, and channels away water, gas, and debris for more consistent braking performance
• Cast Iron Construction — Full-cast, high-carbon grey iron composition delivers excellent thermal conductivity and mechanical strength at both high and low temperatures
• Mill-Balanced — Precision balanced during the machining process to minimize vibration, reduce brake noise, and ensure smooth rotor function from initial installation
• Rust-Resistant Coating — Baked-on protective finish helps prevent brake pulsation, inhibits the rotor from seizing to the hub, and guards against corrosion from road salts and moisture
• Non-Directional Ground Finish — Minimizes thickness variation across the braking surface to extend brake pad life and maintain consistent torque output
• ACDelco Specialty Line — Engineered for performance-oriented applications, meeting ACDelco's stringent standards for fit, form, and function across GM vehicles and many other makes and models

The ACDelco 18A80724XS is a direct-fit rear replacement rotor sold individually. It is quality-validated for proper metallurgy and correct brake plate thickness, making it a reliable upgrade for drivers seeking improved braking response compared to standard OE-style rotors.
