blocks

If you don't have any luck, autozone sells blocks and u bolts together for under $30..I bought my 3" blocks from Peyton and bought some 2" blocks from autozone for the u bolts, bitches were barely long enough lol
 
be careful, theyre aluminum and krusn64 (Scott) had a set....he either has hulk like strength or they are shitty cuz they bent and he almost list his axle.
 
That sucks, I've had mine in for about 3 or 4 months or more with no problems so far, hopefully it stays that way lol thanks for the heads up though
