i have the older model of rough country shackle inversion kit. it is exactly like the trailmaster kit. in fact, its missing a couple of bushing so im ordering them from trailmaster cuz rough country no longer supports the older kit. neither kit mentions anything about providing any lift.
1987 jeep wrangler sport, american racing rims on 31'' rubber, 2'' shackle lift for right now, 4.2 motor with offy intake and edelbrock 4 barrel carb, and lots of extra accs.and built with blood, sweat,and tears
