A shock-isolation structure for supporting a relatively light load on a supporting surface and having a plurality of spring units operable in both tension and compression oriented in a truss configuration with first ends of said spring units connected to the supporting surface for universal movement and with second ends of said spring units connected to the load for universal movement, with each of the spring units including a coil spring, an end cap, and a rod which extends outwardly through the end cap with a clearance fit in a nonextended position, a clevis body on the end of each of the rods, a groove in each of the end caps, and a ridge on each of the clevis bodies for mating engagement when the rod is in the nonextended position to thereby center each of the rods in each of the end caps.
