long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 2000-2006 Mercedes S430?

We know all about the wide variety of parts that make up the faulty air suspension system on your 2000-2006 Mercedes S340. That’s why you’re here, after all- we are The Suspension Experts. These faulty air suspension systems depend on all the complicated electrical parts functioning properly and in sync in order for your suspension to continue working. We wanted to get rid of this dependency, so we created our renowned non-air conversion kit. This kit, for your Mercedes S430, includes one new suspension light module and four completely pre-assembled coil-over struts that are installed with four bolts per strut. We created the kit for our DIYers especially since each wheel can be installed in about one hour. The kit saves you lots of time, and the headache of the dealership replacement, but what about the money? Well, most of our customers will tell you they converted because of the low price. Let’s take a look at the cost difference between choosing an air vs a non-air suspension system. On this page, we compare three prices: that of a dealer repair or replacement of your S340 air suspension, that of installing aftermarket air suspension parts on your S340, and that of tossing out the faulty air ride headache and installing a brand new Strutmasters coil-over suspension conversion kit.

long-icon-xIs Your Suspension Failing?

How do I know if my 2000-2006 Mercedes S430 Air Suspension is failing?

We are The Suspension Experts, and we want to teach you about the common signs of a failed or leaking air suspension in your 2000-2006 Mercedes S430 so that you can properly diagnose it yourself. You will want to get a bad suspension fixed immediately because the S430 will never be able to maintain its appropriate ride height. All other major components will begin to wear out, and then you’re too late. So, the most common sign is a sudden noticeable uneven height difference between the S430’s different sides. It’s common to see the rear end sag, while the front end remains inflated. This makes the S430 look like it’s squatting down too low to the ground. Some drivers notice leaning from the left to the right side, or vice versa. If any of these visible changes are present, a suspension repair or replacement is likely needed. Also, check the instrument cluster for an illuminated warning light or message. Lastly, look at the air compressor. If it is not working or running too often (will be very noticeable and loud), then you may have a bad suspension.

long-icon-gearVehicle Components

What kind of suspension does my 2000-2006 Mercedes S430 have?

The 2000-2006 Mercedes S430 is built with the following suspension components: 2000-2006 Mercedes S430 Air Springs (x4)- (models with air suspension only). 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. 2000-2006 Mercedes S430 Hydraulic Reservoirs (x4)- (models with hydraulic active suspension). If your model of Mercedes-Benz has this, then the steering pump also pushes hydraulic fluid to your 2000-2006 Mercedes S430 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. 2000-2006 Mercedes S430 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. 2000-2006 Mercedes S430 Air/Hydraulic Lines- tubes that run from a compressor to the air struts (or a hydraulic pump to the hydraulic struts for models with hydraulic active suspension), which carry pressurized air to the air bags (or hydraulic fluid to hydraulic struts) in order to adjust the height of the vehicle, respectively. 2000-2006 Mercedes S430 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. 2000-2006 Mercedes S430 Compressor Assembly- (models with air suspension only). 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. 2000-2006 Mercedes S430 Hydraulic Pump- if your Mercedes has hydraulic suspension instead of air suspension, then the hydraulic steering pump will also serve as the reservoir for the hydraulic fluid going into the struts. 2000-2006 Mercedes S430 Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height. 2000-2006 Mercedes S430 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 2001 s500 Mercedes Benz hydraulic suspension failed. So instead of having it replaced with oem struts. I called Jason @ strutmasters and purchased the coilover conversion kit. I paid my mechanic 500 usd to install it. Contrary to peoples opinion about Strumasters and negative review of the product on the Mercedes Benz forum, the s500 ride is super smooth and performed like a new car. I drove the vehicle at different speeds from normal city driving with lots of stop and go and freeway driving @speed 75 up to 140mph when it’s safe to do so for 2 weeks and my conclusion is that the Strutmasters coilover kit is superbly manufactured and performed very well. I rate it from 1 to 10, believe it a happy 10. Thank you Strutmasters for a great product. And saving me money. God bless the USA and God bless all of you @ Strutmasters!
