Alignment after AAL?

Hi there, I recently had the recall done for the new leaf springs. During the installation they told me they couldn’t reinstall the block lift that was installed because they had cut my u-bolts to get the old leaf pack off, and the provided bolts were to short. So I had them install the new leaf pack with no lift in the rear. I drove all winter looking like an idiot with a heavy load in the back. During the winter I had the truck realigned when I got new winter tires put on my rims.
I have now added the AAL lift to the rear to bring the truck back to level. My question is, do I need to get the truck realigned now that I installed the AAL in the rear? I didn’t touch the front since it was realigned in the winter. I just bought brand new tires and don’t want to wear them down with the truck not being aligned properly. Let me know what you think. thanks!!

 

Being solid axle, the rear has no alignment specs that you can change. Can do pretty much whatever you want back there and it won't change anything alignment-wise.

 

TECHNICALLY, lifting the rear will reduce caster up front and will change toe ever so slightly by virtue of the change of caster among other things

2in at the back on a DCSB / ACLB will tilt the truck forward ~ 0.9* (0.818* for DCLB). This will directly correlate to a reduction of the same amount in caster, when we are setting truck around the 2.5-3* caster mark, a change of .8-.9* is quite a bit. There will also be slightly more weight on the front of the truck which might reduce front height and change caster/camber/toe.

Id recommend an alignment CHECK, but if things were good beforehand tirewear should be fine, just might drive a little more floaty.

 

Ok thanks for the responses, I’ll probably get the alignment checked just to confirm. But I won’t worry to much about it.
