The Jeep J-Series Pickups were introduced for the 1972 model year. The J-Series were a range of pickup trucks that were created when Jeep rebranded the Gladiator (SJ). J-Series trucks were initially offered as J-2000 or J-4000 variants, but they were later renamed the J-10 and J-20 respectively. The Jeep J-Series pickup trucks were in production until 1988.
