Have done some research and wanted to follow up with a question regarding my truck (shown here)...after taking measurements (from ground to edge of wheel well) Im noticing a 3" difference from front & back (36" in front, 39" in the back) and when looking on RC website, it looks like the standard level is 2" -- they also have a 2.5" level kit as well but the price jumps $100 Why is the 2.5" kit so much more money and am I even looking at the right one? Any help from someone who has done this before is super appreciated! https://www.roughcountry.com/gm-leveling-lift-kit-1305-10.html?find=2018-chevy-silverado-1500-4wd-739610#278=516
