Fleet & Heavy Duty


Heavy-duty and fleet vehicles and equipment are specialty applications that require specialized parts for repair. These vehicles may be equipped with air brake systems, and may have electrical systems with voltages that differ from traditional 12-volt automotive systems.

Air Brakes

Air brakes are common on many box trucks, over-the-road trucks, and fleet vehicles. Any leak in the air brakes can cause the system to drop below the required air pressure and cause the brakes to lock up. We carry the parts you need, from air compressors to wheel end parts, to repair or replace your air brakes. This includes brake drums and shoes and air disc brake pads and calipers for complete maintenance or repair.
