blocks are fine if you don;t mind axle wrap,,or the possability of them snapping in half or spitting out..sure,,a wrap bar will take out the wrap,,but it won't fix the other two problems..there are keepers you an build to help keep the blocks from spitting out,,but as long as you stay on top of the u-bolts and keep them tight they work..I'd look for other options though..like lowering you shackle mount over using a block..
