So i bought my truck having already been dropped with what I believe is a 4/7 drop which i turned into a 4/6 with shackles in the back to level it out. the problem I am having is that my front end camber adjustment is fully maxed out as negative as i can go and both sides are reading 0.8 degrees positive camber which is right on the edge of being out. From what i have gathered info wise they make a 1/2 inch shorter control arm which I believe would give me full adjustment so I can get my numbers around 0.0 to 0.2 which would be ideal. Any input or ideas would be appreciated as to what you think about it. I was also curious if rather then spending $300 on new ones from djm, if I could just go back to stock upper arms for the time being and be able to adjust my camber accordingly. Im sick of the outer tire wear on my $200 tires on a lowered truck and id like to be able to take a turn at a decent speed Thank you for any help that is given.
