Why do it twice? i will almost guarantee you'll be collecting parts for a 4link within 6 months of putting leaves on. Easy wheelbase ya, excessive wheelhop, shitty departure angle, bending and breaking leaves......i also dont believe the sidehill stability. I have very little in everything to stretch the rear of mine and could have done it for cheaper i'm sure.
I watched those videos. Notice the first video he lifts his rear left tire going through that while the next guy was planted the entire time, then the toyota lifting tires, on leaves. I'm not saying leaves are the worse thing, i'm just saying that a link suspension is far superior. They're predictable and simple. My tacoma will stuff the tires and flex pretty damn good, but it lifts the tires like hell and hops like hell. my 82 would axlewrap like a sombitch, you couldnt spin the tires to warm them up or anything it would be like riding a bucking bronco,although worn out springs were the cause of that. I don't give a **** what jeepforum says, leaves dont belong on the rear of a TJ.
