My Comanche has a Rusty's 5.5" lift kit and I have been completely satisfied with it. (5.5" taller front springs, lower control arms, spring over conversion in the rear, Rough Country shocks & sway bar disconnects, Rusty's adjustable track bar, ZJ solid tie rod, 31's with slight rubbing up front in full flex.)
When we had a small problem with a brake line bracket a fax to Rusty's when their office was closed prompted Rusty to call us right back. He had a different bracket made for us and shipped it right out. I'm in a 4x4 club that wheels in Colorado's beautiful Rocky Mountains so my Comanche with it's Rusty's 5.5" lift has seen a lot of action on moderate to hard trails, (usually hauling all the gear). I've never had a problem with any Rusty's parts and my family has since bought Rusty's parts for two other Jeeps.
Rusty's even offers a Comanche 5" lift rear leaf spring now so you could get 5" of lift without doing the SOA conversion. With the SOA it's 10.5" of lift so you know what I am saving up for! :brows:
