Daystar Leveling Kits work within the factory suspension design, meaning that we work within the factory's design parameters to achieve an increase in ride height that levels the stance of the vehicle. Because we work within the factory's design, there are not a bunch additional modifications involved. Everything needed is included in the kit; there's everything you need and nothing you don't. If there are extra items required, such as longer shocks, it's clearly stated in the application description. This product ships in approximately 1 days
