I have a 3.5 inch lift with 35s. Whenever i go over a bump over 50mph i basically lose control. I do have the stock steering stabilizer, if i get a better once such as the bilstein 5100 will this solve my problem?

 

Death wobble, or does it just dart off in another direction.

I would think an alignment check would be first on the list.

 

It sounds like bump steer. How much actual lift did your 3.5" lift give? If you are at or over 4" of actual lift you may want to install a drop pitman arm. A stabilizer will only mask the problem. You should fix the problem first.

 

Your drag link and track bar need to be at the exact same angle and parallel to each other. If one is at a different angle, then as your axle compresses, it doesn't go up evenly. This causes it to turn, hence the feedback to the steering wheel. With proper steering geometry, steering stabilizers don't do much. And even if you do upgrade your steering stabilizer, if you're angles are off your problem will still persist.

So you fix the angle by different methods- usually a drop pitman arm will lower your drag link on the driver side to match a track bar bracket that's usually also installed with a proper lift. Ideally you want the drag link and track bar to be as horizontal as possible.

 

Its a pretty true 3.5"


Its not death wobble, just darts off in another direction like you said

 

Then your first move should be to get an alignment check. You can't really fix anything 'til you know where the alignment is. Toe and caster, mainly, and axle centering.

 

Also with the 2doors it's worse, but caster plays a huge roll as well. I wouldn't recommend correcting it with bolts but instead do it with control arms. However I have stock control arms and once you dial in your toe right and fix your steering angles, the caster being off doesn't effect it too badly- or at least its not noticeable. This is on a 4 door in which the added wheelbase helps stability to begin with.
