3" Ultimate Installed - Truck Wandering

I have a 2007 dbl. cab 4x4. I installed 3" Ultimate lift, 17x9 (4.5 backspace) wheels and M/T Baja ATZ 285-70-17 tires. I still have factory UCA's. My truck wanders on the road to the point that it's not uncontrollable but drives me crazy. Could this be cured with the Light Racing UCA's or would it be an alignment problem. I do know that some of it can be contributed to the wider tires wanting to follow the grooves in the road. If I do need UCA's can I install or is it a project that should be left up to a professional. (I installed the lift with a buddy with above average mechanical skills.) It has been aligned but still have front tires leaning out at top, they told me to bring it back in a week or two so that they could check to see if the alignment needs adjusting. The mechanic told me that the lift needed time to settle and that's why they wanted me to come back.
I really don't want to by another set of front tires if it would be cheeper to go ahead and get the UCA's.
Thanks I would really appreciate the assistance - any assistance!

 

Thanks, I really like to keep things as close to factory specs as possible. I guess it would be different if the thing was paid for. lol

 

I have almost the same setup with the UCA's and have no trouble with mine. Maybe the UCA's will help.

 

Sounds like alignment issue to me, mine has a 3" with stock UCA's, no wandering issues at all.

 

Well even though the LRs aren't "factory" they do keep the alignment specs at factory levels.
