They both have their perks. Body lift; tho cheap is a Pain in the dick to install, especially if your new to trucks. BUT people would argue this not cool because the truck is more top heavy. I have a body lift, and personally dont feel a damn thing. Now suspension, yes tho a little more pricey its safer, and I feel its much eaiser to install. That is if you really like to wrench and get dirty. Just make sure to get an alighnment after. Oh and correct size tires.
