The stock one is fine unless you are running wheels with quite a bit less backspacing. Stock wheels (depending on which ones you have( have anywhere from 6-6.8" back spacing. Many aftermarket wheels have around 4-5" back spacing. Which 15" wheels having 3.5-3.75". If the tire is sticking out farther (less backspacing) it allows the tires to apply more leverage to the knuckle. When one tire hits a bump, and the other does not (r at a later tim), the bump can push back on the tire. With stock back spacing this would not do anything, as the wheel is centered with the knuckle. But with some aftermarket wheels that have less backspacing, the tire being pushed back can cause it to turn some. Which will then cause you to feel it in the steering wheel. A steering stabilizer can help negate this effect.

But I would wait to see if you actually feel any difference after putting the tires on. Chances are you wont.

 

Mine got bent and leaked oil, Death Wobble started, went to 4wheel parts and picked up a gas Procomp one for $34 today, going to fit it tonight. Seems a hell of a lot stronger than my stock one.

 

I'd run without a stabilizer for a few days to make sure you didn't tweak something else.

 

I found out that an aftermarket SS helps out alot more than people think. Before i got mine every bump i hit weather im wheeling or just a bump in the road my steering wheel would jerk real hard to one side. I mean it got so bad to the point where i could't drive on an end lane because i was scared i would hit a bump and end up over the curb and hit a light pole or something. It got pretty bad and no matter how hard i would grip the wheel i had no control. I took it to get looked at and my alignment was good, my suspension was tightened and everything was fine. The local 4x4 shop suggested an aftermarket SS since im running wider tires than what my stock one is made for. 33x15. They said my 3" lift can make it worse too. So i got the Rc Dual ss and right away i felt a big difference. Thats why i dont understand how some people say its not worth putting one on. But the people that do have them say its 10x better than stock. I guess to each his own

 

You were experiencing bump steer. This is caused by the changed geometry of your suspension after a lift. You should research this, because there may be a way for you to actually fix it.

This is why most folks don't recommend expensive SS set-ups--replace the stock one with a modestly priced one when it breaks; relocate it with something like Wood's/JeepSWAG kit to protect it from trail damage.

 

Yeah, I totally agree with Mark as more caster will give you a more solid feel on your front end, reducing the flightiness or darting.

Here's a quick write up on it from WOL,

OK i get you. So then how did my SS stop what my problem was? I mean by no means im not a mechanic and this jk is my first jeep i have ever owned for about a year now. There is still alot of things i have to learn. Just asking?

 

Positive caster will make it easier for your front wheels to return to center.

Negative caster will make it more difficult for your wheels to return to center.

With a lift, and retaining the factory control arms, you decrease positive caster.

Positive caster will take less intervention to keep your vehicle going straight.

Negative caster will make your vehicle darty, drift more and take more effort to control.

The downside of too much Positive caster is that will make your vehicle more difficult to turn, potentially creating an understeer problem and plowing the front tires.

Negative caster will make it easier to get into turns, potentially creating an oversteer problem making the rear end feel loose.

In a short wheel base vehicle, understeer is more desirable so if your steering feels loose or darty, and especially after hitting bumps adding more positive caster is very helpful.

 

I'm not a mechanic, either. LOL. However, while a beefier/dual SS can stop bump steer, the problem with the steering geometry is still present. A well-running JK can be driven just fine without a SS--or so WOL has attested to on this forum and I trust his advice. There are ways that are often successful to fix bump steer (correct the steering geometry so the wheels continue to go straight when a bump is hit) rather than just dampen it (stop the wheels from reacting to the forces that are trying to push it to one side). I suggest that you read here for some background info on bump steer ...

and then do some searching here on JK-Forum. There are plenty of people who have actually gotten their rigs fixed. In the end you may decide you want to keep you RC dual SS. But, I was just addressing your statement, "Thats why i dont understand how some people say its not worth putting one on."

 

I had great results in solving a death wobble issue and also getting my handling dialed in better after I removed my steering stabilizer. Trying to resolve front end suspension and steering issues with a steering stabilizer installed is like trying to type with mittens on.
