I have Icon Leaf Springs with the Add-A-Leaf and Camburg 6" Length Drop Shackles Installed, but want to reduce the rake more. A$$ end still sits up too high, and my Fox Factory 3.0 coilovers are already cranked up 3 full turns, so can't go higher up front(according to Fox). Anyone gone to a Foutz Motorsports 7" Ext. Length shackle in the rear to get more level? Any feedback or suggestions? Don't want to reduce my loading capacity by switching out the add-a-leaf. Prefer keeping the add-a-leaf in for when I do load it up with add'l spare and gear.
