I have a buddy that wants to lift his zj. i was wondering if you need adj trac bars and such for 5in of lift? Any help would be great. thanks

Yes, all your links for that matter should be adjustable to dial in caster/pinion angles.

Agree'd

I am at 3" of lift, with all new LCA's, Front adjustable Track bar. and rear track bar relocating bracket.. The bracket is just not enough in the rear, the axle is still 1/2" off...
