The model designations were simplified for 1974, with the J-2000 and the J-4000, which designate wheelbase, being swapped out for the J-10 and J-20, designating payload capacity. Larger brakes were made standard and the turning radius was reduced. The Quadra-Trac system was now available with all engines. The AMC was offered from 1974 through 1978. These engines are known for their toughness and excellent power output. The 401 engine produced and of torque. For 1977, Jeep J-10 pickups included Dana's manual four-wheel-drive system, a more powerful six-cylinder engine, and heavier axle tubes, while power front disc brakes became standard equipment and the considerably greater gross vehicle weight rating (GWV) capacity J-20s included AMC's V8 engine. The engine was optional, as well as full-time Quadra-Trac and both automatic and manual transmissions. 1983 saw the new full-time four-wheel drive system, Selec-Trac, replace Quadra-Trac. From 1981 to 1985 a re-bodied version of the J-10 was built and sold as the Jeep CJ-10, featuring a CJ-like nose and cab, as well as a very boxy redesigned rear truck-bed, somewhat resembling that of a Land-Rover. Chrysler bought out AMC in 1987. The full-size Jeep Pickup line was not only an aging model, but also competed directly with the broader range of Dodge trucks. Chrysler discontinued the full-size Jeep trucks, but continued to build the luxurious and highly profitable Grand Wagoneer, which shared the chassis with the large pickups. After the Chrysler buyout, the compact Jeep Comanche pickup (based on the Jeep Cherokee (XJ) platform) received only minor changes and its production continued until 1992. Military versions Military versions of the civilian Jeep pickup included the M715 and M725, built from 1967 to 1969. They were built under contract for nations in addition to the United States. The idea was to reduce costs by starting from a civilian truck and sharing parts with the normal production-line truck, like the later "Commercial Utility Cargo Vehicle" (CUCV) for the military as a ton tactical vehicle. The Swedish Air Force acquired 450 Gladiator vehicles in the early 1980s. They were given the local designations Klargöringsbil 9711 and Klargöringsbil 9712, with the latter variant being equipped with a hard cargo bed top. The vehicles were modified to
