Why Choose Strutmasters Instead Of Those Other Guys

We have already seen the assortment of parts that construct the air suspension system. Our conversion kit gets rid of having to depend on all of those parts functioning correctly and in sync. This conversion kit consists of (1) new suspension-light module and (4) completely pre-assembled coil-over struts that are as simple as 4 bolts per strut for installation. It normally only takes about an hour per wheel for installation, and is designed for DIYers! The conversion not only saves you time and frustration, it saves you lots of money. Now let’s take a look at the cost difference between choosing an air vs. a non-air suspension system. Here, we are going to compare three prices: the price for repairing your air suspension system at the dealer, the price for installing aftermarket air suspension parts on your vehicle, and the price of getting rid of the faulty air ride heartache and installing a brand new coil-over suspension conversion kit:

How Do I know If My S550 4MATIC Air Suspension is failing?

The most common symptom of a leaking or failed air suspension is a sudden noticeable uneven height difference between different sides of the vehicle. The vehicle could have a sagging rear end or front end, it could lean to the left side or right side, or the entire vehicle could be squatting down lower than normal. Other symptoms could include a suspension warning message or light in the instrument cluster, or the air compressor no longer working or running way too often (which would be very noisy and noticeable). The last major tip is your vehicle is no longer able to reach or maintain the proper ride height.

Suspension Components List



What kind of suspension does my 2007-2012 Mercedes-Benz S550 4MATIC have?



The 2007-2012 Mercedes-Benz S550 4MATIC is built with the following suspension components:



2007-2012 Mercedes-Benz S550 4MATIC 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.



2007-2012 Mercedes-Benz S550 4MATIC 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.



2007-2012 Mercedes-Benz S550 4MATIC 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.



2007-2012 Mercedes-Benz S550 4MATIC Air Lines- tubes that run from a compressor to the air struts which carry pressurized air to the air bags.



2007-2012 Mercedes-Benz S550 4MATIC 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 spring. 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.



2007-2012 Mercedes-Benz S550 4MATIC Compressor Assembly- creates/sends pressurized 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.



2007-2012 Mercedes-Benz S550 4MATIC Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.



2007-2012 Mercedes-Benz S550 4MATIC 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.

My name is Elizabeth, let me tell you first, the customer service was friendly and informative, product arrived on time. I converted the air suspension on my 2002- S500 merz to strutmasters
suspension, the mechanic who removed and installed the parts found that the instructions that came with the struts made the job easy, but refused to finished the electrical part, he didnt want to cut the wires as indicated with the instructions, but I was able to locate a STRUTMASTER video on their website, I followed the instruction and I was able to do the electrical wiring myself. Thank you for saving me thousands of dollars.
