Ok I m doing my research before starting my 4" lift and SYE project. I have read quite a few threads. Most say I NEED Adjustable Upper control arms. Done, ordered them already. But there have been a few that say I NEED adjustable lower control arms. But my skyjacker kit comes with extended lower control arms. I would like to use my extended lower arms and adjustable upper arms to set the correct pinion angle. Am I going to have issues with this? Has anyone done this? Any input is welcome thanks.
