CJ Models

The Jeep CJ (or Civilian Jeep) is a public version of the famous Military Jeep from World War II.

The first CJ prototype (the CJ-2) was introduced in 1944 by Willys, and the same basic vehicle stayed in production through seven variants and three corporate parents until 1986.

A variant of the CJ is still in production today under license. The last CJs, the CJ-7 and CJ-8, were replaced in 1987 by the Jeep Wrangler.

CJ-2

CJ-2
Production 1944-1945

Although it bore the CJ name, the CJ-2 was not really available at retail. The CJ-2s were merely prototypes used for testing purposes. Willys produced slightly more than three dozen CJ-2 Agrijeeps in 1944 and 1945, forty in all [1]. It was directly based on the military Willys MB, using the same Willys Go Devil engine, but stripped of all military features, particularly the blackout lighting. Apart from having a side-mounted spare tire and an external fuel cap, the CJ-2 was the first jeep to feature a tailgate. Eleven CJ-2s are known to have survived to this day [2].

CJ-2A

CJ-2A
Production 1945-1949

Lessons learned with the CJ-2 led to the development of the first full-production CJ, the 1945-1949 CJ-2A. Like the CJ-2 and the military MB, the CJ-2A featured a split windshield. An early column shifter, which was introduced because it was thought that troops returning from WWII needed a change in the Jeep, and full floating rear axle gave way to the more familiar floor shifter and semi-floating rear axle. For CJ-2A production, the T-84 transmission was replaced with the beefier T-90 three speed transmission. It is of interest to note that many of the early CJ-2As were produced using surplus military Jeep parts such as engine blocks and, in a few cases, modified frames. Since the CJ-2A was intended to be used as an agricultural vehicle, it was geared lower than its military counterpart, and could be purchased with a variety of options such as a rear PTO and front counterweight. A total of 214,202 CJ-2A Jeeps were produced.

CJ-3A

CJ-3A
Production 1949-1953

The CJ-3A was introduced in 1949, and replaced the CJ-2A by the next year. It featured a one-piece windshield with a vent as well as wipers at the bottom, and a beefed up suspension to accommodate the various agricultural implements that were being built for the vehicle.[1] Another difference was a shorter rear wheelwell (the wheelwell from the top front edge to the rear of the body is 32 inches (810 mm) on the 3A compared to 34 inches (860 mm) on the 2A) and moving the drivers seat rearward.[2] A bare-bones Farm Jeep version was available starting in 1951 with a power takeoff. A total of 131,843 CJ-3As were produced before the series ended in 1953.

CJ-4

CJ-4
Production 1951-1953
Wheelbase 81 in (2057 mm)

Only one CJ-4[3] was ever built as an experimental concept in 1951. It used the new Willys Hurricane engine and had an 81-inch (2,057 mm) wheelbase.
The CJ-4 body tub was an intermediate design between the straightforward raised hood from the CJ-3B and the all new curved body style of the CJ-5.
The design was rejected and the vehicle eventually sold to a factory employee.

CJ-3B

CJ-3B
Production 1953-1968

The CJ-3B replaced the CJ-3A in 1953, the same year Willys was sold to Kaiser. It introduced a higher grille and hood to clear the new Willys Hurricane engine. The CJ-3B was produced until 1968 with a total of 155,494 produced, although the design was licensed to a number of international manufacturers, including Mitsubishi of Japan and Mahindra of India. Mitsubishi ceased production of vehicles derived from the CJ-3B design in 1998 after selling approximately 200,000 units.[3] Mahindra continues to produce Jeeps today.

Related DJ-5

The CJ-5 was influenced by new corporate owner, Kaiser, and the Korean War M38A1 Jeep. It was intended to replace the CJ-3B, but that model continued in production. The CJ-5 repeated this pattern, continuing in production for three decades while three newer models appeared. “The CJ-5 has the distinct honor of being a vehicle that was hard to kill off… equaling the longest production run of note.”[4] A total of 603,303 CJ-5s were produced between 1954 and 1983.

In 1965, Kaiser bought the casting rights to the Buick 225 cu in (3.7 L) V6 Dauntless and the CJ-5 and CJ-6 got a new engine with 155 hp (116 kW) supplementing the Willys Hurricane engine.

A similar model, the Jeep DJ, was based on the CJ.

The company was sold to American Motors (AMC) in 1970, and the GM engine was retired after the 1971 model year. (GM’s Buick division repurchased the engine tooling in the early 1970s which served as the powerplant in several GM vehicles.) The “Trac-Lok” limited-slip differential replaced the “Powr-Lok” in 1971.

American Motors began using their own engines in 1972. Replacing the Hurricane was the one-barrel 232 cu in (3.8 L) (except in California). Optional was a one-barrel 258 cu in (4.2 L) (standard in California). Also in 1972, AMC’s 304 cu in (5 L) engine became available in the same tune as a base V8 muscle car. To accommodate the new engines the fenders and hood were stretched 5 inches (127 mm) starting in 1972 and the wheelbase was stretched 3 inches (76 mm). Other drive train changes took place then as well including the front axle became a full-floating Dana 30.

In 1976 the tub and frame were modified slightly from earlier versions. The windshield frame also changed meaning that tops from 1955-1975 will not fit a 1976-1983 CJ-5 and vice-versa.

In 1979, the standard engine become the 258 cu in (4.2 L) that now featured a two-barrel carburetor.

From 1980 to 1983, the CJ-5 came standard with a “Hurricane”-branded version of the GM Iron Duke I4.

Several special CJ-5 models were produced:

  • 1973 Super Jeep
  • 1977-1983 Golden Eagle
  • 1979 Silver Anniversary

Early Tuxedo Park models were trim lines, but the Tuxedo Park Mark IV was claimed as a separate model than the other CJ series (marked in 1965 as the “Universal”), with more differences than past models. The Tuxedo Park Mark IV was an attempt to crack the mass market; it was, according to Jeep, “a new idea in sports cars … the sportiest, most FUNctional car on the automotive scene.” It added to the standard CJ chrome bumpers, hood latches, gas cap, mirror, and tail lamp trim. 81 and 101 inch wheelbases were available, with a variety of convertible top and seat colors, and front bucket seats in “pleated British calf grain vinyl.” Sales of this model, introduced in 1965, were low.[5]

CJ-6

Engine(s) F-head 4 cylinder
Perkins Diesel
225 CID V6 Dauntless
Iron Duke I4
304 CID V8
Wheelbase 101 in (2565 mm)

The CJ-6 was simply a 20-inch (508 mm) longer-wheelbase (101 in) CJ-5. Introduced in 1955 as a 1956 model, the CJ-6 was never very popular in the United States. Most CJ6 models were sold to Sweden and South America. The U.S. Forest Service put a number CJ-6 Jeeps in to use. American sales ended in 1975. Just 50,172 had been made when the series went out of production completely in 1981. Just as in the CJ-5, the V6 and V8 engine choices appeared in 1965 and 1972. Former President Ronald Reagan owned a CJ-6 and used it on his California Ranch.[6]

CJ-5A and CJ-6A

CJ-5A & CJ-6A
Production 1964-1968

From 1964-1968 Kaiser elevated the Tuxedo Park from just a trim package to a separate model for the CJ-5A and CJ-6A. A Tuxedo Park Mark IV is signified by a different prefix from a normal CJ-5 with a VIN prefix of 8322, while a normal CJ-5 VIN prefix is 8305 from 1964-1971.

CJ-7

CJ-7
Production 1976-1986
Wheelbase 93.4 in (2372 mm)

The CJ-7 featured a longer wheel base than the CJ-5 and lacked the noticeable curvature of the doors previously seen on the CJ-5. It was introduced in 1976 and 379,299 were built during 11 years of production.

The CJ-7 featured an optional new automatic all-wheel drive system called Quadra-Trac, as well as a part-time two speed transfer case; an automatic transmission was also an option. Other features included an optional molded hardtop, and steel doors. The CJ-7 was also available in Renegade and an upgraded Laredo model. Noticeable by their different body decals, the Laredo model featured nicer seats, steering wheel tilt, and a chrome package that included the bumpers, front grill, and mirrors. An optional Trak-Lok differential was available for the rear. Ring and Pinion was typically 3.54, but later went down to 2.73.

A diesel powered version was made in the Ohio factory for export only. The engines were provided by General Motors, the owners of Isuzu Motor Cars. Production of this diesel version is believed to have been only between 1980 and 1982. This model had the Isuzu C240 engine, T176 Transmission, Dana 300 Transfer box although there are reports of some being produced with the dana 20. Typically they had 4.1 ratio, narrow track axles.

The CJ-7 continues to be used in the sport of mud racing, with either the stock body or a fiberglass replica. It is also a favorite for rock crawling.

CJ-8 Scrambler

 

Jeep CJ8

 

Production 1981-1986
Body style(s) 2-door pickup truck
Transmission(s) 5-speed manual
3-speed automatic
Wheelbase 103 in (2616 mm)

The (CJ-8) Scrambler was a pickup truck version of the CJ-7, introduced in 1981. It featured a 103-inch (2,616 mm) wheelbase and a pickup bed. Only 27,792 were built in the five years of production before being replaced by the similarly-sized Comanche.

The Jeep Scrambler(CJ-8) did not offer the Quadra-Trac system. The majority of Jeep Scramblers (CJ-8) used the traditional transfer case and manual front-locking hubs to engage the four-wheel drive. Most Scramblers(CJ-8) used a four- or five-speed standard transmission but a three-speed automatic transmission was an available option.

A full length steel hardtop CJ8 based on the Scrambler was made for the Alaskan Postal Service, using right hand drive and automatic transmissions. Instead of the rear tailgate the steel hardtop utilized a hinged barn door opening to the back. There were only 230 of these produced and sold in the US. This version was also widely sold in Venezuela and Australia as the “CJ8 Overlander”, with small differences including full length rear windows on the Overlander. Jeep Australia (Circa 1984). “Jeep Overlander CJ8 Specifications and Dimensions”. Press release.  The steel hardtops used on these postal scramblers and Overlanders were known as “World Cab” tops.

Former U.S. President Ronald Reagan also owned a blue Scrambler (CJ-8) and used it on his California “Rancho del Cielo” property(image)[7] with the license plate “Gipper.”[8]

CJ-10

CJ-10
Production 1981-1985
Body style(s) 2-door pickup truck
Engine(s) 3.7l 6 cylinder

The CJ-10 was a CJ-based pickup truck. Produced from 1981 through 1985, it was sold mainly as an export vehicle, though some were used by the United States Air Force for use as an aircraft pulling vehicle. They featured square headlights mounted in the fenders and a 9-slot grille, a homage to the old Jeeps of WWII which originally had a 9 slot grille (the civilian model, the CJ-2 and 2a, were given a 7 slot grille as a distinction between the military and civilian models).
