1984 Mitsubishi Jeep J54 Diesel

Description

OFFERED WITHOUT RESERVE

The Mitsubishi Jeep traces its origins to 1953, when Mitsubishi Heavy Industries obtained a license to manufacture Willys‑based Jeeps for use in Japan, initially supplying military, government, and industrial sectors. While Jeep production ended in the United States during the 1960s, Mitsubishi continued refining the original CJ‑3B formula for decades, resulting in a uniquely durable and utilitarian vehicle built to Japanese industrial standards.

By the early 1980s, the J54 represented a mature evolution of the platform. The 1984 model was powered by Mitsubishi’s 2.7‑liter 4DR5 diesel inline‑four, paired with a 4‑speed manual transmission and dual‑range transfer case, emphasizing torque, longevity, and efficiency. The ladder‑frame chassis, solid axles, and leaf‑spring suspension reflected its intended use in agricultural, municipal, and remote‑area service across Japan.

Showing evidence of first ownership in Osaka, Japan, where it was reportedly used as a farm vehicle, this 1984 example was later imported to the U.S. prior to the current owner's acquistion. The seller reports being the third owner and has added approximately 2,000 kilometers since 2021. Outfitted with a Bimini-style soft top, a 10,000‑pound winch, all‑terrain tires, new batteries, and a recent full fluid service, this J54 is well equipped and ready for adventure.

This 1984 Mitsubishi Jeep J54 is now offered with a clean Florida title in the seller’s name.
