Horribly Bouncy ride on freeway?

Hey guys, I picked up a 2023 TRD Pro not to long ago and recently did a longer road trip for the holidays. On smooth road it’s fine, but if the road is bumpy at all my truck bounces all around like you’re sitting in a massage chair. Its horrible. It does have the tow package in the rear and eibach springs up front. I figured it’s probably due to a stiffer ride but I have a hard time believing this is normal. Has anyone had similar issues? If so what did you do to fix it? I’m looking into adjustable fox shocks in the rear since I believe that’s were most of my issue is and adjustable dampening may help.

I haven’t checked tire pressure yet, that may be a contributor but I wouldn’t expect them to be to inflated. It does have a rear tow package, slightly larger tires and eibach springs in the front instead of the factory TRD. Tires and springs were installed by the dealer when it was brand new before I bought it.

 

Shocks

 

Is this your first truck?

 

Tire pressure first. Make sure it’s what’s listed on the door.

 

Shocks, or overlifted. if you put too much preload on the shocks they will ride like that.

 

technically, no. First newer truck. I built an older 3rd gen runner.

 

It’s got the factory fox shocks. The dealer installed Eibach springs and slightly larger tires when it was brand new. It only lifted it maybe a half inch or full inch at most

 

It’s got 16k miles on it and is damn near brand new.

 

Well that detail helps a bit. Still verify no leaking.

 

Its probably the springs, being to heavy of a spring rate.
