Why Choose Strutmasters Instead Of Those Other Guys

When one component of an air suspension system goes bad, the rest of the system follows suit. This is no different for the 2002-2012 Mercedes-Benz SL55. Strutmasters built its air to non-air suspension conversion kit to save SL55 owners time, frustration, and money when its air suspension system fails. The kit, manufactured in the USA, comes complete with one custom-designed suspension light fix module and four pre-assembled coilover struts that are installed with four bolts each. Customers appreciate the detailed instructions and online installation videos that guide the repair. If further assistance is needed, Strutmasters' ASE certified technicians are available to answer questions and concerns. Lastly, the cost of this coilover suspension conversion kit is vastly less expensive than dealership direct replacement and individual part replacement. Overall, this kit is the smartest choice for the SL55 owner.

How Do I know If My SL55 Air Suspension is failing?

It is critical to identify the following signs of a failed or leaking air suspension system before total failure sets in. Look for these indicators, in the 2002-2012 Mercedes-Benz SL55, that the air suspension system is going bad before it's too late. Any inability of the SL55 to reach and maintain its proper ride height is a red flag. Look for one sagging end, one inflated end, a squatting appearance, or a lean from one side to the other. These imbalances, if not fixed promptly, will wear out the air compressor. As a result, a suspension warning light will illuminate. At this point, suspension failure is advanced and a repair will be costly.

Suspension Components List

The 2002-2012 Mercedes SL55 is built with the following suspension components:  2002-2012 Mercedes SL55 Hydraulic/Air Springs (x4)- (models with air suspension only). These plastic and rubber sacks, known commonly as "air bags," sit atop the strut and use pressurized air to cushion the vehicle's ride and hold it off the ground. These components are the number one culprit behind all air suspension leaks. Since they tend to take a similar amount of wear and tear, if one has worn out, the rest are soon to follow. These all need to be replaced at the same time to properly repair the active suspension.  2002-2012 Mercedes SL55 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 suspension components.  2002-2012 Mercedes SL55 Struts (x4)- This metal tube, filled with a gas-charged hydraulic fluid, is a type of shock absorber. It is connected to the wheel of the vehicle and dampens the effect of rough surfaces on the vehicle's ride. It features an air spring on top of the strut commonly known as an air strut.  2002-2012 Mercedes SL55 Height Sensors (x4)- These connections are located adjacent to each wheel of the SL55. It constantly measures the ride height of the car and sends this information back to the suspension computer so that it can determine whether or not each wheel needs to be raised or lowered. Like all moving parts, these sensors will inevitably wear out and need replacing.  2002-2012 Mercedes SL55 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.  2002-2012 Mercedes SL55 Solenoids (x4)- These L-shaped plastic pieces serve as a connection between the electrical connection and the suspension components to the suspension computer. The solenoid regulates the amount of air pressure in each spring. As they begin to wear out, they will cause the car to lean or sag, signaling constant need of attention to the suspension control module. This, in turn, will cause the compressor to overwork and eventually wear itself out, causing total failure of the active suspension system.  2002-2012 Mercedes SL55 Compressor Assembly- (models with air suspension only). This is an air compressor that creates and then pumps pressurized air to the suspension components. This compressor takes signals from the suspension control module, meaning that if one part of the active suspension is malfunctioning the compressor will try to compensate by constantly working. This will lead to early failure of the compressor and soon after, the entire suspension system.  2002-2012 Mercedes SL55 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.  2002-2012 Mercedes SL55 Suspension Control Module- This computer manages the entire suspension system and helps it maintain proper ride height.  2002-2012 Mercedes SL55 O-rings- These o-rings are responsible for maintaining the seals where the air lines connect, making them vital to the proper functioning of the entire system. They should be replaced every time the air suspension is serviced.
