Fix your 2000 - 2006 Lexus LS430 Air Suspension Conversion Kit (TD14F)

If you're having air suspension problems on a Lexus LS430, don't spend a dime on the air suspension, without giving an LS430 Air Suspension Conversion some serious thought. Your Lexus is approx. Ten years old, you can bet the airbags need replacing. This vehicle has a total of 4, so if you have one leaking, it is a good rule of thumb to replace all four at the same time. The problem with being pro-active on the air suspension on an LS430 is that each air strut costly approx. $1,200 each! That's not including a compressor, solenoid, electronic module or solenoids. That's just four parts in a system of 15! The better move would be to convert the vehicle to conventional coil springs. Our kit for the Lexus LS430 will instantly eliminate your air suspension problems forever while retaining the factory ride height forever! Conversion requires no cutting, drilling or welding.

This Lexus LS430 Suspension Conversion Kit Includes:

  • The Best Coil Springs Pre-assembled on Premium Front struts.
  • The Best Coil Springs Pre-assembled on Premium Rear struts.
  • Easy to follow instructions clearly show technicians how to install the new conversion kit.
  • Easy to follow instructions included to cancel out the suspension message on your Lexus.

When installing an LS430 Air Suspension Conversion on ANY vehicle be sure to follow all safety procedures. Make sure that when you lift your vehicle, that you're using a sturdy and dependable jack and jack stands and that the car is parked on a flat and level surface. Failure to do so can result in the vehicle sliding off it's supports and onto you! Make sure you have or can obtain all the tools required beforehand. A list of the tools needed is below, but gloves and especially eye protection should be standard equipment on any job.
Be sure to follow the instructions in the specified order, as they are laid out in a particular order for a reason. Improper installation and even installation in the incorrect order can cause damage to these parts that are NOT covered under your warranty!
