Renew the worn brushes inside your charging unit with the Standard Ignition Alternator / Generator Brush Set, part number RX-99. It is a direct-fit replacement for many vehicles, including the 1965-1971 Chevrolet Impala (L6-4.1L), 1967-1971 Chevrolet Camaro (V8-5.7L) and 1963-1966 Chevrolet C10 Pickup (L6-3.8L). See the Buyer's Guide tab for the full list.
The brushes in an alternator or generator keep sliding electrical contact with the rotating assembly, carrying current between the stationary and spinning parts of the unit. As brushes wear down, that contact can weaken. This part is listed under both names, alternator brush set and generator brush set.
