I have the silver shocks on my truck. My buddy wants to purchase shocks but its unclear to me if the blue and yellows will fit on a truck with stock rear suspension and a front leveling kit. When i bought mine Geno's told me that the blue's won't work with a 2 inch leveling kit. Does anyone know if this is true? He would like to get the blue and yellow because they are specific to the truck as oppose to the silvers which are a universal shock. Thanks in advance.
