Location: Puyallup, WA

Why It's Curated: This 1973 Jeep J4000 QuadraTrack is for sale in Puyallup, WA. The J4000, Jeep's full-size pickup built on the Gladiator platform, represents one of the more overlooked segments of early 1970s American 4x4 history, and this example carries the QuadraTrack full-time four-wheel-drive system that was genuinely ahead of its time. The 360 cubic-inch V8 has been modified, though specifics weren't provided by the seller. Suspension has been lifted three inches, and the truck rides on 17-inch aftermarket wheels paired with 35-inch tires, a practical combination that improves trail capability without compromising the truck's period character. The grey exterior is complemented by a grey and black leather interior. Paint and body work has been performed, details of which were not disclosed. This truck suits a buyer who wants a rare, usable classic American 4x4 pickup with room to further develop or simply enjoy as-is.

Model History: The Jeep J4000 represented the long-bed, three-quarter-ton variant of the SJ-platform full-size pickups, positioned alongside the short-bed J2000 during its four-year production run. Built on Jeep's enduring Gladiator truck platform, the J4000 featured a 132-inch wheelbase and offered both manual and automatic transmissions paired with AMC engines — reflecting Jeep's shift toward standardizing American Motors Corporation powerplants across its truck lineup. The 1973 model year brought interior and mechanical refinements, including an AMC-pattern dashboard, repositioned engine, and double-wall bed construction that addressed earlier single-wall shortcomings. By 1974, Jeep rebadged the lineup as J10 and J20, retiring the J-series nomenclature after a quarter-century of truck production.
