What should i choose?

What lift kit holds its height the best? and has the best travel? i currently have a superlift 4" kit and it has sagged a lot and its only been on there maybe 2000 miles. i know that different lifts may be slightly taller then others so which sets the highest for a 4" kit. ive heard the RE 4.5" is good ne one run it? just give me some opinions so i can make a decision on what to do.

 

contact superlift and tell them what's happened
obviously use could dictate what happens to the springs
I have no experience so my comments are limited to the above

 

I put BDS springs on both my jeeps. 3.5" lift Wrangler springs on the 74 and a 2.5 lift kit on the 77. The wrangler springs on the 74 sagged a significant amount. To the point that I am going to have to move my shackle mounts. The rear shackle started out pointing toward the front of the jeep. Further than I wanted to leave it. I was going to drive the jeep for a while and see where it ended up. Now my rear shackle is at such an angle toward the back of the jeep that I actually will need to move it toward the back. I think the soft springs like that are really prone to sag, or settle in or what ever you want to call it. My 74 sits perfect now aside from fixing the minor shackle issue.

The 77 springs have hardly moved since install. I carry a lot of trail tools and parts in this jeep. It also sports a steel hard top and plow in the winter. I have used it like that with the new springs for a couple years and it has held up incredibly well. But I certainly wouldn't trade the ride quality of the 74 for the 77.

 

Jim, i know that use can change things on the springs but i havent been wheeling on it, only road driven and i dont carry loads just the weight of the jeep! i was thinking about going spring over and saw the full traction bolt on kit for doing so, ne one used it or heard ne bad things about it?
