Riding Through Time: The Story of Vintage Jeep Trucks

In 1963, Jeep pickup trucks emerged onto the automotive scene, boasting fresh, clean lines that defined an era. Fast forward to 1987, and these once-boxy trucks, with angular lines and chrome embellishments, find themselves in the spotlight again, standing out amidst the sea of modern, plastic-infused counterparts. The classic Jeep trucks, once deemed outdated, now enjoy renewed appreciation in the vintage truck market, fetching prices three times their original value.

Jeep Truck Model Designations
Navigating the intricacies of early Jeep trucks from the 1960s and 1970s can be a challenge. Originally labeled “Gladiator” under Kaiser’s ownership, the 1963-1970 trucks were categorized into J-200 or J-300 variants, with numbers denoting wheelbase lengths rather than weight ratings. Post-1970, Kaiser introduced J2000, J3000, and J4000, each offering varying wheelbases and weight ratings. Following AMC’s acquisition of Jeep, the Gladiator moniker was dropped in 1972, leading to the introduction of the J-Truck. From 1974 to 1987, the J-10 and J-20 models, with diverse bed options and GVW capacities, dominated the Jeep pickup landscape.

Old Jeep Pickup Factory Engine Options
The classic Jeep truck witnessed a parade of I-6 and V-8 gas engine options throughout its production. Starting with the 1963-1964 models powered by a 230ci OHC inline-six, subsequent years saw engine upgrades, including a 232ci OHV inline-six and the introduction of a 327ci Rambler-sourced V-8. The engine lineup continued to evolve, incorporating Buick-sourced 350ci V-8, AMC’s 258ci inline-six, and various V-8 options such as the 304ci, 360ci, and the formidable 401ci. Despite changes, the Jeep truck maintained its reputation for increased pulling and hauling capabilities, becoming a powerhouse on and off the road.

Shifting Through the Gears
Jeep pickup transmission options kept pace with the diverse engine lineup. Early models featured the T-90 three-speed and later the T-98 four-speed, with an AS-8W three-speed auto as the slushbox option. Subsequent years saw a transition to T14 and T85 three-speed manuals and the introduction of the TH400 three-speed auto. As the engine options expanded, so did the transmission choices, with the T-15, T-18, and Borg Warner T-14A and T-15A becoming the go-to manuals for different engine configurations.

What Transfer Case Came In Old Jeep Trucks?
In the early years, the Dana 20 gear-driven transfer case dominated the Jeep truck lineup, offering robust strength in a compact size. The Quadra-Trac T-case, exclusive to automatic TH400 transmission, introduced a full-time option. Over the years, transfer case options expanded, featuring NP219 and NP228 for full-time applications and NP208 for part-time use, boasting a favorable 2.61:1 low range.

In unraveling the history, generations, and specifications of old Jeep trucks, one discovers a legacy that transcends time. From the Gladiator’s debut to the evolution under AMC’s reign, these trucks have left an indelible mark on automotive history. With diverse engine options, transmission choices, and transfer case variations, the classic Jeep trucks embody resilience and versatility. Whether seeking a vintage ride or simply appreciating automotive history, the old Jeep trucks stand as enduring symbols of craftsmanship and off-road prowess.
