a shimmy in the steering wheel is almost always a tire balancing problem. even if you already had your tires balanced, have them balanced again. it's not uncommon to have to have large off road tires balanced multiple times to get them on right. a steering stablizer should not be used to hide or mask problems of this nature.

 

Wayolife hit the nail on the head. I put on TF 2.5" coil lift (for 4 dr on my 2 dr) and got well over 3.5" of lift at the stock Rubi Rock Rails. I put on MT MTZ 33's. I was also told by several knowledgeable people that the stock steering stabilizer is fine. No need to upgrade until needed. My JK is a semi DD and I wheel it on the weekends moderately. No problems with steering. When that stabilizer goes out, then I will upgrade to something nicer at that point.
Save that money for other needed mods! My $.02 for what its worth!

 

You just beat me to the point i was going to make. I picked up a relocation bracket for mine and just a basic, inexpensive Pro Comp stabilizer. I would say the relocation is the more important purchase. I would have used the stock stabilizer if it didn't get smashed

 

Agreed. Unless you're running 40s or larger the stock one will do.

 

I totally agree with Wayoflife, stay stock if you can. The stock stabilizer can handle the 33’s. I have Bilstiens but I crushed mine on a rock. I wish I would have just relocated it so it wasn’t so low. The gas charged one have a slight push to them because they are always wanting expand.

 

Just to add my . The people that said you do not have to upgrade the SS are correct. The purpose of a SS is to stop bump-steer. This is what happens when you are hauling a$$ down the road and hit a pothole, or something else, in the road with only one tire.

The SS dampens the reaction of the steering down to a slow, steadying motion. It resists a sudden jerk as in the above mentioned scenario. As WOL and others have mentioned so many times, a SS should never be used to mask other issues.

In a normal situation a SS is not needed, it is there so you do not lose control like you might if bump-steer happens. But, if you drive without one you are betting on your journey nothing will cause bump-steer and with it a possible wreck.

A hydraulic SS does this by being filled with fluid and there only being a small passage for the fluid to move through as the rod/piston is stroked (try to resist a joke here). As you know fluid does not compress so, it takes time and effort for the rod to be moved. And as you can plainly see a SS does not help the steering to return to center, it actually is trying to keep the linkage exactly in the same position.

It is possible with big enough tires the amount of additional mass may overwhelm the stock size diameter SS but the 33" tire is not even close. The other reason to replace it is looks or, as in my case, I repositioned mine and needed swivel ends to prevent binding.

 

I went with the Jeepswag mount and stabilizer. It is a KYB but mainly I wanted the beefier mount and location.

 

I have the Skyjacker Dual Steering Stabilizer and it works great. Maybe a little more pricey but works like a champ.
