Iatco Truck Parts

Illinois Auto Truck Co., Inc., known as IATCO, was founded in 1939 by Fred Greenberg as an independent truck parts jobber in the Chicagoland area. IATCO began manufacturing and supplying replacement components for the rebuilding of heavy duty clutches in the early 1940s and Fred Greenberg’s son-in-law, Leonard F. Stein joined the company in 1946.

By the 1960s the truck parts jobbing aspect of Illinois Auto Truck wound down in favor of concentrating on the manufacturing of heavy duty replacement clutch components.

Now a fourth-generation family business, IATCO’s unsurpassed customer service, on-time delivery and technical expertise has truly made them “Best in the Clutch.”
