The King's don't really require the maintenance everyone thinks they do when comparing them with pre-runner trucks and rock crawlers. They are performance shocks, but they're not getting abused to the same level. The Kings are estimated to have 30k-40k mile maintenance checks. These aren't throw away shocks like the others. They're easily worked on by anyone with the tools, or any local offroad shop. The question is, what do you want out of your suspension. If you want the best handling and control on and offroad, you want the Kings. If you want a budget suspension system with just better than stock expectations, then you can get the other brands.
