CJ-3B: The CJ Model was updated in 1953, becoming the CJ-3B, with a taller front grille and hood than its military predecessor in order to accommodate the new Hurricane F-head four-cylinder engine. The CJ-3B remained in production until 1968 and a total of 155,494 were manufactured in the U. S.
JEEP CJ- 5: 1955 saw the introduction of the CJ-5, with a rounded front-fender design. It was slightly larger than the CJ-3B, as it featured an increased wheelbase and overall length. Improvements in engines, axles, transmissions and seating comfort made the CJ-5 an ideal vehicle for the public’s growing interest in offroad vehicles, and more than 600,000 were produced.
JEEP CJ- 6: Featured a 20-inches longer wheelbase and offered more cargo space. A forward-control cab-overengine variation was added in 1956. Both the CJ-5 and CJ- 6 were equipped with heavier axles, bigger brakes and a wider track, and in 1965, a new “Dauntless” V6 engine was introduced as an option. This 155-horsepower engine almost doubled that of the standard four-cylinder engine, and it was the first time a Jeep CJ could be equipped with a V6.
