The J-Series Pickups was a full sized pickup truck produced from 1963 until 1987 under several model designations during its production years. The J-Series Pickup truck model numbers were used to identify the trucks wheelbase and GVW and had changed over the years.
From 1963 until 1964 a 3 digit number was used to identify wheelbase and GVW (gross vehicle weight) of the vehicle. Models were available with a 120" and a 126" wheelbase and most models were available in Thriftside (narrow box), Townside (wide box) and cab & chassis models. Early models were know as Gladiator pickups.

In 1965 Jeep changed the model number to a four digit number with the exception of the J-100 panel delivery truck. In 1967 the two wheel drive models were dropped. In 1970, the Gladiators received the same style grill as the Wagoneer, which was the first styling change since its introduction. 1971 marked the end of the 3000 series and in 1972 the "Gladiator" name was dropped and the J trucks were simply called Jeep trucks.

In 1974 the model designations were changed to only reflect vehicle load capacity rather than load capacity and wheel base.
