I just bought a RC 4.5 kit for the MJ i am building....compared to previous kits i have seen, the quality and appearance are improved....it was well packaged and more complete than i expected....the parts are suitably beefy for my intended use....it's a short arm kit so it WILL ride harsh on the highway....but the on road ride isn't a problem in my case....a nice fluffy set of 12.5/33 TSLs will take care of those pesky road slab expansion joints while i'm on the way to the mudhole...and once i bounce it thru a few ruts and holes, those front springs will break in. Now where did i put my SawZall??
