Koni FSD shocks for Class C Motorhome

Note that Koni offers only one set of FSD shock part numbers that supposedly are for BOTH the E350 and the E450.

This doesn't seem right to me: In order to properly deal with the additional weight that an E450 chassis under a motorhome most likely would be carrying, the same part number FSD shock would be overall too stiff for an E350 - wouldn't it? While in order to properly deal with the less weight that an E350 chassis under a motorhome most likely would be carrying, the same part number FSD shock would most likely be overall too soft for an E450 - wouldn't it?

You can't have it both ways without a compromise somewhere somehow. I would feel more comfortable with the E350/E450 FSD shocks that Koni is offering if they had different part number sets for the two different chassis.

I'll probably soon (42,000 - 44,000 miles on our current original Ford shocks) try these new Koni FSD shocks -> taking a slight chance that they'll make a pretty good improvement in the hits from highway cracks. My E450 chassis is lightly loaded with our RV - as an E350 chassis could easily carry our motorhome's weight - so the current FSD shock set Koni is offering will probably work great for us.

To my knowledge, we've had one Class C owner to add FSD's and he thought the ride was slightly worse. He has not reported back. I don't know if there's a break-in period for them. There was for some Monroe automotive front struts.

I put them on my KODIAK Super C and they did improve the ride they are designed to soften the "hit".

I may install them in the rear only, sometime this year, and will post here on how they perform. However, we have only a small 24 foot Class C but on the heavy duty E450 chassis ... so it needs something in the rear for those lateral highway cracks.

The newer Michelin M&S"2" tires I put on it help too, but I'm hoping that the FSD Koni's step up the comfort another notch.
