I have a 2013 Jeep Jk with a Mopar Stage Three 3.5 inch lift. I am running 20x12 with 35 in tires. It has a Fox ATS steering Stabilizer on it. This thing is flighty.I mean it swerves at any slight input on the steering wheel.I understand it shouldn't drive light a Lambo but it has to drive better than this for sure.
Any help would be greatly appreciated.

 

Sounds like a caster issue. Have you had an alignment since you upgraded the suspension

 

That's actually a decent kit. The control arms are fixed which should have caster close to spec ?
Do you have a alignment sheet ?

I mean caster is what it is with the control arms.
Toe can be easily set in your driveway.

Did you try adjusting the fox ATS ?

The installer could of not loosened all the CA an TB bolts. Installed the lift and torqued everything down with the axles hanging. This would cause issues.

 

I have not had a alignment since install. Was told this kit didn't require a realignment. And I have heard horror stories of the local 4x4 alignment shop.

 

Have ATS set just over half way.
How do I adjust toe and or check the toe?
I believe that when the kit was installed it was on the lift and tightened up but have not got a answer on that question when I asked. I own a automotive business and that is one thing we make sure we do when we replace suspension parts.
Since I have no spec sheets for the torque sequence or torque amount list from MOPAR I haven't loosened anything yet. MOPAR does not list this info that I could find. I might try Teraflex and see if I can get the info.

 

TB's 125
Lower CA's 125
Rear upper CA's 125
Front upper CA's 75

I Believe there's a alignment DIY on this site in the sticky area.

Toe is good at 1/8 "in" meaning the fronts of the wheels are pointed in,

I wouldn't take much to loosen all the bolts, shake jeep and re-torque with weight on the axles.
Then use a paint marker to draw a line across the bolt/nut heads for quick visual.

 

So use the paint marker across nut and bolt to mark how tight the nut/bolts need to be... Good idea. Okay I will check this.
I know for a fact that if ( and I believe it was) tightened in the air this is not good. But pretty simple to do.

 

Well it's just a quick visual after you torque everything down. Always make a habit of checking torque every few K or after wheeling,

I use a Harbor freight 24" breaker bar and anchor it against the ground. This helps you torque the bolts by yourself.

 

Crap.... Check psi #1

Dealerships/shops like to over inflate tires.
A 35 will have good tread contact around 25 psi.

20" wheels are going to run a little rough. Just a note.

 

Okay I will check tire pressure first! Thanks for the input. This might be the ticket cause this thing rides like a brick. Little bumps will jar the teeth... Will not that bad but it sure doesn't ride good not even close to stock. I figured a little rougher ride but not like this.
Thanks will let you know.
