When it comes to leveling you get what you pay for. This great new system specifically incorporates more than just front leveling. The addition of our track bar relocation bracket allows you to correct your truck's track width after lifting the front. Something that is necessary on some new Super Duty trucks. The sound isolator is installed between the spacer and spring to retain that great OEM ride and quiet sound. Shock extensions allow you to retain the use of those great riding brand new front shocks rather than having to replace them with cheap aftermarket versions. In addition, Ford changed the front suspension on the new 2017 Super Duty trucks and in order raise the front of the truck the front sway bar frame mounts must be spaced downward. ReadyLIFT designed new sway bar mount spacers just for this reason, something you won't get with other kits. ReadyLIFT® Smart Suspension Technology is used to make this kit very user friendly to install, requiring no cutting or drilling.
