The ACDelco 18A2804XS is a Specialty Performance front disc brake rotor engineered for demanding applications including fleet, police, and heavy-duty service. Backed by General Motors and built to stringent OE tolerances, this rotor delivers reliable, consistent stopping power designed to outlast standard replacements in high-cycle environments.

Key Features:

• Specialty Performance designation — purpose-built for fleet, police, and heavy-duty duty cycles requiring enhanced durability
• Cast iron construction with damped metallurgy — reduces noise and dissipates heat more efficiently under sustained braking loads
• OE-matched vane configuration — mirrors original manufacturer vane design for optimized airflow, cooling, and reduced wear
• Non-directional rotation — eliminates the need for separate left- and right-hand designations, simplifying installation and inventory
• Thickness variation under 0.0004" — minimizes pedal pulsation and brake noise while extending brake pad service life
• SAE structural integrity compliant — manufactured with G3000-qualified material to meet SAE standards for strength and performance
• No machining required — ready to install straight out of the box
• Independently tested — subjected to Noise/Vibration/Harshness (NVH) and durability/wear testing for verified quality
• Inspected for balance — ensures smooth brake operation and noise reduction from the first stop

The ACDelco 18A2804XS is sold individually. As part of the ACDelco Specialty brake lineup, it is designed, engineered, and backed by General Motors — making it a trusted choice for professional technicians and fleet operators who need dependable braking performance under elevated demands.
