The CJ-5 Initially referred to as the Willys CJ-5 but was changed to Jeep CJ-5 after 1964. The CJ-5 brought a short wheelbase and a narrow frame to the table which allowed them to fit into places other off-road vehicles couldn't go.
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 having the longest production run of any US vehicle.
