I used 2 "hardened rubber spacers" (NHL approved) on each side to give the 2" lift I needed...I actually left it at about 1 3/4" to give a little extra space between the bumper and body. The "spacers" were perfect as they are hard enough to keep everythign tight but have a minimal amount of give to not have any rattles or anything in my beat up front bumper. Will post pics as soon as I get some....
