I currently have a set of 1 1/2" Fabtech rear lift blocks on my truck and was going to change them out for a set of Superlift 2" rear lift blocks. Does brands matter with blocks? Is Superlift just as good as Fabtech?

 

I have to say, a block IS a block!!

 

did you stac k the block on the factory block? if so id get a taller block equel to the 2 and get rid of the stacked ones
