The Jeep CJ-8 was a long-wheelbase version of the CJ-7, introduced in 1981 and manufactured through 1986. It featured a 103.5 in (2,629 mm) wheelbase and a removable half cab, creating a small pick-up style box instead of using a separate pickup bed. CJ-8s used the traditional transfer case with manual front locking hubs to engage the four-wheel drive. Most had either a four- or five-speed manual transmission, but a three-speed automatic transmission was an option.
The term "Scrambler" comes from an appearance package with which many CJ-8s were equipped, which included tape graphics and special wheels. Former President Ronald Reagan owned a CJ-8 and used it on his California ranch.
A full-length steel hardtop CJ-8 was made for the Alaskan Postal Service, using right-hand drive and automatic transmissions. Instead of the rear tailgate, the steel hardtop used a hinged barn-door opening to the back. Only 230 were produced and sold in the U.S. It was also widely sold in Venezuela and Australia as the CJ8 Overlander, with small differences, including full-length rear windows on the Overlander. Steel hardtops used on these postal Scramblers and Overlanders were known as "World Cab" tops.
