Default Suspension issues

Guys,
I have installed the RC 2.5 Premium lift on my 2010 JK Mountain, I've had three alignments, and tye steering is still a little wonky.. floating.
Wondering if anyone has the same suspension upgrade and find their steering this way or find that their shocks are a liitle soft.I also have the RC dual steering stab.Im wondering if I should upbrade to the Bilstein 5100's or are they too harsh of a ride?


Any recommendations on replacing sway bars etc?

Thanks in advance.

LCA's increase your caster a bit.

On the floating, squirrelly, flighty steering: check you castor angle, more than likely it's around 2* when you want at least 4*+.
You can go with front control arm drop brackets or front lower adjustable control arms. The least expensive is cam- bolts. The front lower adjustable control arms are the pricey way to go, but you get what you pay for. The other two methods can not adjust the degree of castor more than a few degrees, so may not offer what you look for. Air pressure will also have some affect on your steering and ride quality.

Alignment was in spec, as per manufactures spec.

"Wonky"... steering is unpredicatable and feels like its wandering all over the road, alot of side dipping on turns.
Oh I also have 1.5'' wheel spacers.

Kit includes the following.

Kit Contents:Front: Coil spring spacers, brake line brackets and performance 2.2 shocks.
Rear: Coil spring spacers, brake line brackets, track bar, sway bar links and performance 2.2 shocks.

Im pretty sure the alignment guys said the Castor cannot be adjusted, mainly the toe.................

I would say Front Lower Control arms are the fix since your kit does not include them.

On your kit do the replacement sway bar links place the new bars in the rear and moving the original rear bars to replace the front sway bar links?

Re: flighty wandering- you have to adjust your castor to 5 or 6 degrees, more than the stock 4.2* ( don't go too high so you don't get drive shaft vibration ) From my prior post there are 3 ways of doing this.

Re: side dipping, body lean in turns - these are your stock springs with spacers between the springs and frame. So the lean was always there, just now exaggerated due to a higher center of gravity. Stiffer shocks that change the dampening can reduce the roll, but you will pay by a harsh ride. And it's not the best way to fix this concern.

If you, on your jeep, want to avoid leaning in turns then stepping up to quality springs with tuned shocks is the answer. Yes, it cost more money. So you have to find that balance that works for you.

So if I get the lower adjustable control arms, better springs and shocks, another wheel alignment, all will be good?
How about lower control arms, and the rear end, anything for back there.
What would you recommend for springs and shocks, that are not too soft and not too hard?
