Upgrade from the regular Load Lifter 5000 to the Load Lifter 5000 ULTIMATE built specifically for the NEW 2015-2019 Ford F150 4wd. The Ultimate series created by Air Lift includes an exclusive 3 stage jounce bumper that will replace your worn out factory jounce bumper while still providing you with all the other "Load Lifter" benefits. Made from closed cell urethane foam the aftermarket bumper will absorb shock and further protect your F150 during times of heavy load without the need for maintenance. The new jounce bumper can run safely with zero air pressure and will properly compress as weight is added to your vehicle. The 88385 kit from Air Lift has been tested to fit the 2015-2019 F150 4WD and is considered "top of the line" when it comes to dealing with load support and ride stability.
To top it all of you can have this kit installed onto your Ford in about 2 hours and are covered from manufacturer defects with the Air Lift Limited Warranty
As an added bonus you may want to look into installing an Air Lift on board compressor in order to manage spring control with the touch of a button
