Got my lift on and took the truck for an alignment. Since I don't know anything about it i'm wondering if you guys could tell me how these specs are? The numbers seem to vary side to side a lot to me?

I added a 6" Tough country lift
Bilstein shocks
Superlift dual steering stab with Bilsteins
Rock Krawler Adjustable track bar
Will get some pics up soon

 

That doesn't look bad at all. Overall caster is good, between 3 & 4 degrees, slightly less positive on left to compensate for road crown.

Camber isn't terrible, less than 1/4 degree difference side-to-side. Ideally, the left would be slightly more positive, but it's well within reason.(and not adjustable).

Toe looks good, a bit more than 1/16" toed in, right where it should be. Thrust angle is less than .1 degree, so you know your rear axle is straight.

One small concern is that your rear wheels have negative camber. (they lean in at the top). The right is pretty slight, but the left has twice that amount. Likely cause is that your rear wheel bearings have a bit of end play, or maybe a slightly bent spindle. It's not the end of the world, and not worth getting upset about, but I thought I'd point it out.

Anyway, it looks good and should handle well.

 

That sounds good, thanks a lot for the reply. I just bought the truck last year with 58k miles on it, put about 12k more on myself. It handles great and everything looks good to me as far as I can tell, but a few things like a 30k gooseneck hitch and the type of hard plastic air bag type things on the rear point out that it might of been doing heavy hauling. It didn't concern me a lot when I was buying it because it was in such nice shape so it looked to be taken care of well. As far as the rear, is there anything to look into this matter more? Is the only effect going to be a tiny bit of abnormal wears on my tires? I am pretty easy on the truck, but I do haul a sled deck in the winter and it will see 3,000lbs+ on the rear end so I don't want any weak links.

 

I don't think there would even be any abnormal wear on the rear tires. If the rear wheels were toed in or out, then it may scrub some tread off the edges, but with just a small amount of camber they will wear fine. Next time you have the rear rotors off, you can check for some end play worn into the axle bearings, but I wouldn't bother taking it apart just for that. If I recall, on the AAM axles like yours, it's not always possible to lock the adjustment exactly where you want it, so you may end up with some end play.
