Hey guys I just purchased a slightly used Skyjacker 4" lift and it came with 3.5" aluminum shimmed block. I found out that every one makes them out of cast iron now, but I'm not too concerened about strength. These blocks are forged, what I need to find out is if I'm going to be sitting level. Does any one have a slighty older Skyjacker lift with these blocks? Wondering if I shouldn't find some regular 4" blocks. Thanks, Matt. Displacement, cubes, and did you say you drive a riceburner???
