1952 CJ Coiler, the First TJ You think the TJ was the first Jeep utility coiler? Think again and lookee here! In the early ’50s, Willys began development of a four-wheel-drive independent suspension system. This is one of the early iterations that included coils, swing axles, and portal hubs. It isn’t clear if this design was actually built, but a later iteration was constructed on a CJ chassis and featured front and rear independent suspension with a wishbone SLA (short-long arm) design that used torsion bars. This development led to the IFS offered in the ’63-’65 Gladiator truck and Wagoneer SUV.
