If you go on jeepforum.com you can see many messages about rough country under the YJ section. One of rough country's reps' is actually a member on the site too. They have changed there leaf spring manufacture and apparently it is night and day compared to the original springs from Rough country.
The guy on the forum will even answer all your questions about the lift. Heard there is good warranty too. Lots of guys who had the old style leafs
had them sag and they just sent pics to the rep and they got replaced for FREE!!!! There are lots of good write ups on the forum too about guys liking the
lift.
Personally I would rather deal with a company that has great consumer relations then a company who just sells ya the lift but then hangs you
out to dry on stuff like parts missing from the kit or saging leafs. Mind you BDS has great customer service too but there lifts are three times as much.
But the bds lifts do come with more stuff.
I am looking at getting a rough country 4" lift come summer unless i got with an e-locker.
Gemini sales out of vancouver sells the lifts so no worries about the pesky cross boarder UPS charges.
http://www.gemini-sales.com/index.htmlMy two cents is for $550 my as well try for a first lift kit. You prob will wanna go with a SYE and CV driveshaft tho just to help the angles.
