I recently purchased an 07 Sport with 85k on it. The X-REAS isn't leaking yet and it has new tires on it. I'm looking to level it until the tires wear out or the shocks start leaking. What is the best kit for this? Is there a larger kit that I could just use part of it to level for now and add the rest when the time comes? If not what leveling kit would you recommend?
