What Makes an Exhaust Parts Manufacturer Different From a Distributor?
A distributor buys from manufacturers and resells. An exhaust parts manufacturer makes the part. Auto-jet has been making school bus exhaust parts since 1959. When a part is older or hard to find, distributors come up empty. We still make it.
Three reasons fleet managers choose manufacturer-direct:
-
OEM-fit parts without middleman markup.
-
65+ years of school bus exhaust engineering.
-
In-stock inventory with same-day shipping.
