The Lexus LS400 was a five-year, one-billion dollar investment for Toyota, designed to be the absolute epitome of luxury, complete with automatic features, California walnut in the interior, and even an integrated cellular phone. The designers thought of almost everything to make the vehicle the perfect flagship for the brand, but Air Lift Performance thought that a change in ride height was in order. Our engineers started on the Lexus LS400's rear kit by adding exactly what our air suspensions are famous for -- maximum drop without sacrificing performance. But getting you low was not enough for Air Lift Performance. Our kits are also about giving you the ability to achieve the versatility that the common coilover cannot provide, eliminating classic lowered-car problems, such as bottoming out, with the touch of a button. We pride ourselves on making sure that every Lexus LS400 kit we build not only provides a great ride, but also handles the curves like a fine sports sedan should. The rear kit features our double-bellow air springs, providing the ability to air out 4.9in from stock. The threaded-body shocks allow for up to 30 levels of adjustability, creating an air suspension that is completely customizable for your ideal performance setup as well as your daily driving needs. As the leader in air suspension products for more than 70 years, Air Lift Company and its Performance division is committed to delivering quality parts that last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components have all been torture-tested to 1 million cycles on our in-house hydraulic test rig at temperatures ranging from -30 F to 150 F. With a one-year, unlimited-mileage warranty -- not to mention the Air Lift Performance reputation for great customer service and technical support, should you run into any snags in the installation process -- you can purchase this kit with peace of mind.

Installation Instructions

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.


    Donald Wojnar
  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.


    Adam Cranston
  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.


    Bryce Budd
  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.


    William Brunell
  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
