Why Choose Strutmasters Instead Of Those Other Guys

We are The Suspension Experts, so we know every detail about the wide variety of parts that make up the faulty air suspension system on your Benz S430. It can be very expensive to take it to the dealership every time one of those parts needs a repair. We came up with an affordable and high-quality solution that eliminates the dependency on all these parts to function properly and in sync, forever. This air to non-air suspension conversion kit includes four pre-assembled coil-over struts that use high-quality Eibach coil springs. This is the only kit on the market that uses performance-driven Eibach springs! We designed the kit to save you time, frustration, and a lot of money in the long run. Most of our customers chose the conversion kit when choosing between an air vs non-air suspension system because of the low price. On this page, we compare three different costs: that of repairing your air suspension system at the Mercedes-Benz dealership, that of installing aftermarket air suspension parts on your S430 individually, and that of getting rid of the faulty air ride headache for good by installing a Strutmasters coil spring suspension conversion kit.

How Do I know If My S430 4MATIC Sedan Air Suspension is failing?

You want to properly diagnose a failed air suspension system when it is still leaking or going bad, instead of waiting until total failure is obvious. There are universal signs to look for in your 2003-2006 Mercedes-Benz S430 4MATIC sedan. The most noticeable is an uneven height difference between different sides of the S430. It might be sagging in the rear or front end but inflated in the opposite end. This gives the illusion the sedan is squatting down lower than usual. Perhaps there is just a slight lean from one side to another. If you notice any issue with your S430 reaching and maintaining its appropriate ride height then a bad suspension is the most likely suspect. Confirm this by looking for an illuminated suspension warning light or message on the instrument panel. Check the air compressor for signs it is not working- a bad suspension can cause it to wear out. Alternatively, if the air compressor is very loud and noticeably noisy then it is running too often- another indicator the suspension is failing.

Suspension Components List

The 2003-2006 Mercedes Benz S430 (4MATIC Sedan) is built with the following suspension components:

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Air Springs (x4) - commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Struts (x4)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Height Sensors (x4) - a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Compressor Assembly - creates/sends pressurized air to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Air Lines- tubes that run from a compressor to the air which carry pressurized air to the air bags in order to adjust the height of the vehicle, respectively.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Solenoids (x4) - usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air bladder. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Dryer- prevents moisture build-up inside of air suspension parts.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

2003-2006 Mercedes Benz S430 (4MATIC Sedan) O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
