General Motors has started to sell its T-Series trucks in 1998. The vehicles were based on the Isuzu’s F-Series medium duty range of trucks and shared the same design and technologies with their siblings.
The Chevrolet T-Series range consisted of three models namely the T6500, T7500 and T8500, all powered by a 7.8 liter Isuzu diesel engine. All Chevrolet T-Series trucks had a cab over engine configurations and were equipped with various Allison transmissions.
The Chevrolet T Series was sold until 2009 and came with GVM (gross vehicle mass) ratings between 24,350 lbs. to 39,000 lbs. and 4x4, 6x2 and 6x4 axle configurations.
