    How hard is it to get the U-bolts off, do I need a really large impact wrench? Also with a 4 inch lift do I need to extend my brake lines?

    A braker bar should get the u-bolts loose. With a 4inch I would reccomend getting some new brake lines. Most 4 inch kits come with brackets so you don't need new lines but if you want to flex it you should get them.

    for the u bolts just spray some pb blaste ron it and uwill be fine.
    extended brake lines are needed if ur gonna wheel, but just street riding u dont.

    Cut the u bolts off. It'll take you forever with a ratchet. An impact wrench would probably be totally useless (always has when I've done it). Usually you destroy them (flatten threads) when you remove them anyway. For the safety factor, I'd replace them.

    Grinder with a cut off wheel. Pops them off in about 1 minute if you get a good wheel. Watch yourself when it comes loose and have a jack under the axle.
    When you put the new ones on you need to set the axle on jack stands to get the weight on the springs. Check them after about 100 miles. They will strech a little and need to be retorqed.
    The EZrides are the ticket for best ride and flex. I hate my Rancho's and about to swap them out after seeing a few trucks with the EZ's. communities.msn.com/OffroadK5s
