A modular independent coil spring suspension for steerable/non-steerable wheel assemblies and driven/non-driven axles having a single coil spring with a low spring rate secured (a) to the lower of two vertically spaced control arms which connect the chassis to wheel assembly on one end, and (b) to the chassis at an upper location approximately level with a tire of the wheel assembly at the other end which provides maximum wheel travel, decreased rearward thrust, and tire/ground mobility.
