Jim, sorry for being so lazy right now (to look it up) but I'm thinking the link you earlier provided left me with the impression the suspension was active (computer controlled) hydraulic. As if there would be no shock absorbers since the "springs" themselves were constantly controlling wheel movement.Originally posted by Tree Machine
What they all have is fully-adjustable , independent-wheel air adjustment dealies that eliminate the need for springs. It's like a smallerized version of the air suspension they use on semi rigs. In other words, you can adjust your suspension with increased weight with the touch of a finger.
