Koni FSD Shocks
Would those members who have installed Koni FSD shocks on their Class C do it again? Or do you regret the decision. Thanks.

Are you saying that an 30 ft rv on a E450 chassis will have a different weight to spring ratio than an 25 ft rv on the E450 chassis? I thought that all E450 chassis in the 2005 year had a rear axle weight rating of 9450 pounds. Are you saying that some E450 chassis have different springs?
The "weight" I'm talking about is the weight of the coach. All E450 chassis of a given year-range have the same coach weight carrying capacity.
When a heavier coach is built onto a given E450 chassis, it's more difficult for the springs to raise the coach up when hitting a small roadway bump. Hence the springs just bend more themselves (than they would with a light weight coach) ... instead of the coach getting thrust upwards as much. This then makes the roadway bump feel less severe inside the coach.
The "ratio" I'm talking about is the weight of the coach versus the weight carrying capacity ("stiffness") of the springs carrying the coach.
