Bouncy ride with Koni shocks

I recently had Koni shocks installed on my rig (2012 Fleetwood Expedition) and seem to notice that sometimes the road surface is just right to set up a rather extreme up-and-down "bounce" to the ride that is significant enough to make me slow down (some sort of resonance). Has anyone else experienced this, and if so is there a way to address it (other than slowing down that is)??

Are those shocks adjustable? My rear Konies were. If so you could have them adjusted for more damping.

Koni Shocks

Had that problem on the rear of my 1999 F53 34 foot motorhome. Put the bilsteins back and problem gone. While the konis were on I had drive shaft balanced, and carrier bearings replaced. Returned them to koni. Now have removed konis from the front.

Had new Koni's installed in June and have driven about 6K miles since then. No problems with bouncing, etc., and a good improvement in ride. I saw the shocks before they were installed and if there is an adjustment, it well disguised.

On some Koni shocks you collapse the shock and rotate the central shaft. Usually have 5 settings.

Are they labeled somehow to identify them as adjustable?

I am surprised at this ... People have spoken so highly about the konis...

Do you have a spartan or freightliner chassis. Koni goes with freightliner not spartan.

Freightliner

It does not happen all the time .. Just when the bumps in the road are repeating and a certain distance apart ..

I had Koni's installed last year on our 2000 American Eagle and it was a Huge improvement in ride performance !
That said what you are talking about can happen and can happen with any type or brand of shock on occasion and yes changing speed is about the only way to get out of the rhythm!!! Nothing to do with Koni in particular that said as with any shock setting them up stiffer if you can (mine are not adjustable) may help.

Regards,

Ed

Traveler: Did you notice this type of bounce with the shocks that you took off?

I agree with RVingDutchman, once you get a bounce rhythm, its off the gas.

I run Koni shocks on all axels except my tag axel. They don't support a Koni installation. On the tag axel I run Bilstein shocks. Between the Koni shocks and running my Toyo tires at 80psi (Maximum pressure with 16" rims) I have no handling problems.

I did not notice this with the previous shocks (not sure of brand ... They were the stock shocks on the new rig). Sounds like in general this can happen, so I'll stick with the koni's (a little bit of improvement, but not as much as I might have guessed ... Though I have been lucky in that this unit has always handled very well ... Never even felt trucks coming up beside me. 😀

Check with the shop that installed the shocks if they are adjustable. If you have FSD's they are not adjustable. If the Koni's you have are adjustable, here is the procedure. You can download it in PDF also.

The FSD's are gold, the adjustables are usually red although the new EVO 99 series I just got are red and are not adjustable, they are like FSD's inside but made for our 20,000# front axle.
