ToyTec ULK (Bilstein/Eibach) CV Angle Question PLEASE HELP

I know this is a very common thread and I'm sorry but after hours of research I still haven't found a certain answer... hopefully this will help future buyers as well! So I have a 4WD 2003 TRD V6 XtraCab (with a semi-heavy tube bumper up front) and I'm looking at the 5100s with the Eibach 3" coils. I know that the shocks should be set to the lowest setting, 0", and the springs will lift the truck 3". Since I have the 4X4, I understand that I need to use the differential drop kit, but will I still have issues with CV angles after the install? I've read people buy UCAs to fix the CV problem but I wasn't sure it's necessary because I see people throw this shit on 4-bangers and expect the same results. Then they follow up with CV complaints. I'm trying to do as the kit says in the description, as it says it's suited for my truck, but I don't want to damage anything. Also don't want install/align just to have to order UCAs later. If anyone has this setup and/or has an answer for me it would be much appreciated!!! Thank you!
