These u-bolts are available in 1/2" diameter grade 5 or fat 9/16" grade 8 for a nice upgrade. They are made to fit the 05+ axle and block height correctly so you aren't left with u-bolts that are a pain to get into the plates and you won't have a bunch of threads hanging down that'll require chopping, which is common with aftermarket grade 3 universal u-bolts. Bumps are Energy to ensure quality and blocks are steel and available in any height with or w/o taper depending on your setup. Either PM for details, or you can order this kit straight from my site by clicking my sig below, going to the products page and searching block kits. Price on the site includes everything, even priority shipping with a delivery #. It doesn't get better than this, only cheaper. This isn't a crappy $32 pep boys kit, it's a bullet proof kit with a real world pricetag. Nothing in the kit is overpriced. This is what it costs to do it right the first time.
