Hey guys. New here to the forums. This may have been discussed... I have looked through some pages and honestly cant get past looking at the pictures of all the awesome trucks builds! I have a 2014 Sierra 1500 4WD Crew Cab. I want to level the truck by lowering the rear. I don't haul anything heavy or tow. However, I have to remember Mom & Dad need to get in sometimes. I was told removing the stock blocks under the leaf springs would level it with the front. Is this true? Or, is the better option to buy the lowering shackles? Thanks in advance!
