"California Hop"

[sik350]

I was on the freeway and once i reach a stretch of highway that is concrete my truck starts to hop..BTW I have a 07' f350 dually. I call ford but they said that the truck does it because of the wieght in the back, but it dosent seem like the trucj hop in the rear but only in the front. Who has had this happen to them? Wut the darn solution? I was thinking of removing the coils and replacing them with airbags.

Never drove a truck that didnt hop when getting onto concrete from asphalt.

thanks bush
i couldnt get it retrieved

but anywho
it did make a difference for us UNLOADED and running 55 psi in each rear wheel ( always run the correct psi as your load requires)

pretty much smoothes out the bouncy bouncy bounce
to a tolerable level

I.E. passenger seat back no longer jumps around

My Ex. did that a little bit until I got rid of the stock shocks and put on some Bilsteins. But my Dads Dually w/stock shocks really hops around on concrete.
