I put the DayStar keys on my 2004, and you will need aftermarket shocks. Ride quality is the same, but make sure you get an alignment or your camber is going to be pretty bad. Just watch you CV boots, as they will wear faster due to friction. I put my leveling kit on about a year ago and you can see and feel the wear marks. I am now looking to put a lift kit on, one of the reasons being that they come with differential drop kits. They allow the CV's to be strait, which is alot safer for them.
