Do yourself a favor. Go with a body lift and not a suspension lift. To illustrate my point, here's Scotty Kilmer pointing out why a suspension lift (if not done correctly) can really be hard on your truck. The one he's pointing out is a GMC/Chevy Sierra/Silverado. No, not a ford ranger, but same thing will happen.
In contrast, body lifts don't do any of what these kits do.
