The Chevrolet/GMC B series (also known as the S-series) are a series of cowled chassis that were produced by General Motors from the 1967 to the 2003 model years. A variant of Chevrolet and GMC medium-duty trucks, the B-series was developed primarily for bus use. While primarily used for school bus applications, General Motors offered the chassis for multiple commercial and specialty uses.
Like the Chevrolet P-series chassis and the Cadillac Commercial Chassis, the B-series is assembled as an incomplete vehicle for second-stage manufacturers, who produced all bodywork aft of the firewall. Initially derived from the medium-duty C/K series, later examples used the GMT530 platform.
General Motors ended production of the B-series line after 2002, with the company concentrating bus production on cutaway-cab chassis. The medium-duty GMT560 chassis was also used for bus applications, but was only produced with a cutaway cab. As of current production, General Motors still provides a platform for both school bus and commercial bus applications, derived exclusively from the GMT610 cutaway van (Chevrolet Express/GMC Savana).
