All this stuff can be bought separately on eBay if missing.MTH said:Not really. Springs do sag over time, but as long as they weren't beat up with a ton of weight they should be alright. Make sure you get all the parts--brake line extensions, bump stops, track bar relocation bracket, mounting hardware, etc.
i would agree on trying to buy lower mileage parts. if you're wary of suspension parts because you don't think they'd hold up to wheeling or time, you probably shouldn't even consider that companies parts to begin with. I have no issue buying quality gear, even over a year old, from teraflex or old man emu or any of the other big names. just be sure to check out what people have to say about that companies parts before you buy. some folks, like rough country or pro comp, are known to make cheap parts that just dieI personally would avoid buying a used lift kit unless you were very sure it had low miles and was well taken care of. Knowing how fast some of them wear out and how hard people (especially Jeep people) can be on their Jeeps off road, I'd be wary of buying suspension parts used.
