I don't think I need a coilover suspension like Downey offers. I'd like to do a spacer lift. I'm having trouble deciding between Cornfed and Revtek. Cornfed's rear blocks are aluminum and it states on the cornfed website "Aluminum block are VERY prone to breakage." On the other hand, Revtek uses plastic. I guess I'd rather have aluminum. Who makes a better product? I was thinking 3" of lift. Also, what kind of shocks do you guys recommend?
