As I send you into the rabbit hole...... making the upper arm shorter will cut down on room for the shocks at full droop. Frame notching may be required. But, leaning your shocks in will give them a better motion ratio,
You sure you don't want to cut the front of your truck off?
Uh oh retard alert. My lower arm was .5" shorter than it should be. Fixed that and new numbers are 1.7 camber at droop, 4.1 at bump and 1/4" bumpsteer at both droop and bump. Still planning to make shorter upper and new mounts on frame.
