So I've just finished installing the 2" Rough Country spring kit, along with all new front end parts. Not bad, the kit only sat in my shop for 6 months before I got around to putting it on. Everything went well, and the ride is fantastic. Just enough lift for me. My question is: When doing an alignment on the SFA trucks, I was under the assumption that camber is not adjustable. Seems like the local shops are split 50/50 on this one. Some say you can use an eccentric sleeve on the upper ball joint,and some say no. I also say no, since that sleeve sets the preload for the upper ball joint. All the eccentric sleeves I have been shown are not threaded, therefore doing nothing for the ball joint preload. My best guess is that when installing these, you would use the castle nut to set preload, but I really don't care for that idea. The caber looks fine to me, however I want a proper alignment. If that includes eccentrics for the camber, then so be it. Just sounded off the wall to me though. Thoughts? Thanks in advance!
