I hear what you’re saying. Trouble is, most level kits just give you spacers, and keep all the other factory components, except shocks. What I did know was that the Boss springs gave me a 700lb. spring rate which is a bit heavier than factory and that was a must have for me. Factory springs were way too soft I thought. So I wanted to improve my ride and not go too high as you stated with the lift, and I won’t go any larger with the tires than what I have already. Plus, they are adjustable while on the truck as opposed to having to remove them, compress the springs, disassemble, adjust, reassemble, reinstall. A lot of work if you wanted a small change. Bottom line is, I agree with you. IF you like the factory ride and aren’t afraid of just spacers to achieve lift, then go with a leveling kit. If you’re like I was and wanted an improved ride (less bounce, more planted), and a wanted to level your truck out some, then I think these are hard to beat. They are a bit pricier than some of the kits out there, but their overall ride quality and ease of adjustment was worth it for me. They also use a longer, heavier spring to lift which I liked better than spacers alone.
