How tall can you go with a leveling kit on the new 2500's? I see some people on forums referring to their leveling kits as 3 inch kits. But all of the popular kits I see are 2 and 2.5 inches tall. Or maybe they are referring to the actual height they gained. For instance, I have 1.75 inch Daystar spacers on my Jeep Wrangler but I actually gained 2 inches of lift.
