Are these mediocre alignment numbers?

[MattH]

I recently installed the Ford Perf/Fox leveling kit, Icon tubular UCAs, and BDS 1" shackles on the rear and got it aligned on Friday. I'm not too happy with how it drives now for a few reasons and think part of it might be the alignment numbers.
It's got a slight pull the left, I'm assuming because of the uneven caster they put in so I'll be calling them about that on Monday. But I would think with Icon UCAs it should be able to have quite a bit more caster with less camber than what they got. Is this just a lazy alignment?

You don't want lower camber than that and the caster looks fine, you do want a 1/2 degree spread(or so) from left to right to compensate for the crown of the road, you may have a tire pull, get the shop to cross the front tires side to side, unless you have directional tires, then you would have to settle just rotating the tires front to back.
This alignment looks fine

It had factory tires on and pulled to the left, and this morning I got new tires and it pulls just the same so that’s not it

Hi Matt,

My take is too much caster split.

So from my experience on the Old Man EMU lift with the alignment I have the camber and caster right about the same. I want to say my caster is 2.4° on both left and right if i remember correctly. Also something I noticed was I had to check the toe with my fat ass in the truck since it would go out when I got in it. I probably had to do that since the lift has soft offroad springs with the longer travel. I will send you a pm here soon.

I put my leveling kit in last weekend and got an alignment on Thursday. They did a good job and it drives great. Here is the readout they gave me if you would like to compare..

I can already see a problem and it will get worse. The toe is out and I have a feeling when you get in the drivers seat it gets worse. I had this on my ranger and I have had to adjust it twice since installing the Old Man EMU lift after the springs settled.

Thanks, I'll hit you up in PMs to discuss!

Are those specs just with a fox leveling kit and no aftermarket control arms? If so, I don't see why me putting on the Icon UCAs was really worth it...

Hi Chris

You bring up a good point of a change in dynamic toe. I have found that toe out will result in the truck hunting back and forth more than a pull to the left in my experiences, but having toe adjusted with driver in the seat makes a lot of sense.
