Exaggerated shake/bounce of truck when i hit a bump?

Driving down the road my truck is fine, as soon as I hit a bridge joint or bump in the road, my truck seems to exaggerate it about 10 times more. Could this just mean shot shocks or something else? I have had 3 F-250s and not one of them rode this rough when hitting a bump or even sometimes on flat highway roads.......it gets kinda annoying after awhile.

Do you have the Ford 20'' wheels with those OEM Goodyear tires? It's my belief that those tires are pure trash. I've got that setup on my truck now, and are having the same problems. I have noticed that you do need to keep them aired up near the recommended inflation to help eliminate some of that exaggeration of bumps. Seems like they want to bounce more like a basketball when you ride on them with less air.

Your sig lists a Newton 2.5" front lift.....was anything done to correct your caster setting when this was installed?


If not, it's most likely your caster is too negative.


Is your stock stabilizer still on the truck? If so, remove it.

If dual stabilizer in your sig is on the truck, then I would take the stocker off if it is not.


If that leveling kit doesn't come with caster cams, you'll want to be sure to get them. Much more likely to get death wobble without them.

Remember it's also the weight of the oem 20" wheels. They are very heavy and the tires pronounce the bounce.
