Lexus GX 470 Air Suspension is made up of two Air Spring Bags in the rear, which is inflated by the Air Suspension Compressor. A Height Sensor tells the Control Module that the vehicle needs to be raised. There are two Gas Shocks in the rear, as well in the front of a Lexus GX 470. Suncore Industries has many of these parts available for purchase. Air Suspension Conversion Kits are also available, which will eliminate the GX 470 Air Suspension completely. Your Satisfaction is our Guarantee!

Air bag or air strut failure - is usually caused by wet rot, due to old age, or moisture within the air system that damages it from the inside. Air ride suspension parts may fail because rubber dries out. Punctures to the air bag may be caused from debris on the road. With custom applications, improper installation may cause the air bags to rub against the vehicle’s frame or other surrounding parts, damaging it. The overextension of an airspring which is not sufficiently constrained by other suspension components such as a shock absorber may also lead to the premature failure of an airspring through the tearing of the flexible layers.Failing of the Air bag may also result in completely immobilizing the vehicle. As the vehilce will rub against the ground or be too high to move.
Air line failure – is a failure of the tubing which connects the air bags or struts to the rest of the air system, and is typically DOT-approved nylon air brake line. This usually occurs when the air lines, which must be routed to the air bags through the chassis of the vehicle, rub against a sharp edge of a chassis member or a moving suspension component, causing a hole to be formed. This mode of failure will typically take some time to occur after the initial installation of the system as the integrity of a section of air line is compromised to the point of failure due to the rubbing and resultant abrasion of the material. An air line failure may also occur if a piece of road debris hits an air line and punctures or tears it.

Compressor failure - is primarily due to leaking air springs or air struts. The compressor will burn out trying to maintain the correct air pressure in a leaking air system. Compressor burnout may also be caused by moisture from within the air system coming into contact with its electronic parts.
In Dryer failure the dryer, which functions to remove moisture from the air system, eventually becomes saturated and unable to perform that function. This causes moisture to build up in the system and can result in damaged air springs and/or a burned out compressor.
