Airtex 5A1110 Alternator Brush Set

The Airtex 5A1110 is a direct-fit replacement alternator brush set designed to restore proper charging system function. Alternator brushes are carbon contact components that transfer electrical current to the rotor's slip rings, enabling the alternator to generate the voltage needed to charge the battery and power vehicle electrical systems. When brushes wear down, symptoms such as a battery warning light, undercharging, or complete charging failure can occur.
