Why Choose Strutmasters Instead Of Those Other Guys

Strutmasters' air to non-air suspension conversion kit saves GL320 owners time, frustration, and money when the air suspension system on the vehicle goes bad. The kit, manufactured in the USA, is an affordable direct replacement alternative to dealership replacement or repair. It comes complete with two new Eibach coil springs with mounts and two passive hydraulic fluid and gas shocks for the rear. Customers appreciate the detailed instructions and online installation videos that help them get the kit installed in about one hour per wheel. If further assistance is needed, our ASE certified experts are on hand to answer questions. The quality parts are backed by Strutmasters' Lifetime Limited Warranty, too.

Compared with dealership prices, and individual aftermarket part prices, our coilover suspension conversion kit is the smartest choice.

How Do I know If My GL320 BlueTEC 4MATIC Diesel Air Suspension is failing?

Early detection of a failed or leaking air suspension system is critical to avoiding total failure. Look for the following signs that indicate the air suspension system on the GL320 BlueTEC 4Matic is going bad. The most noticeable is a sudden height imbalance between different sides of the GL320. A sagging rear end with an inflated front end is commonly seen. There may be a shifting lean from one side to the other. The vehicle may look like it's squatting down too low to the ground. These height variances will wear out the air compressor, if not addressed in a timely fashion. If the air compressor has already ceased working, a suspension warning light will turn on in the vehicle. At this point, suspension failure is advanced and an expensive repair is needed to get the vehicle fixed.

Suspension Components List

The 2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC is built with the following suspension components:

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC Air Struts (models with Active Dampening Suspension) (x2)- shocks whose dampening capabilities are controlled by the suspension control module.

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC Coilover Struts (models without Active Dampening Suspension) (x2)- A type of shock absorber, it is a piece of 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. Coil springs fit around the top portion of the struts and hold the vehicle up, they are rated for and designed to work with the rest of the suspension system.

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC Shock Absorbers (x2)- a 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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC Air Springs (x2)- 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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC Air Lines- tubes that run from a compressor to the air springs, which carry pressurized air to the air bags.

2009 Mercedes-Benz GL320 BlueTEC Diesel Solenoids (models with Active Dampening Suspension) (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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 4MATIC 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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 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.

2009 Mercedes-Benz GL320 BlueTEC Diesel 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.

After having a problem with the air ride suspension on our 2008 Mercedes GL450. We began doing research for replacement options (because all four “bags” had previously been replaced at a pretty high price, but the system was failing again.) It seemed that the best option would be to convert the vehicle to a spring/strut suspension system.
Research showed that I could get a cheaper foreign made spring/strut system but the reviews indicated that they were a lesser quality system than the heavier, American made system made by Strutmasters.
I contacted Strutmasters and was fortunate enough to be connected to Donielle. Donielle is excellent at her job as she was knowledgeable, friendly, and went out of her way to get answers to all of my questions. I found that Strutmasters products were 100% American made and manufactured right in Roxboro, NC. I learned that I could have the replacement system manufactured and shipped to a local mechanic to install but didn’t feel confident with most local mechanics I spoke with about their confidence level to do the work.
When I mentioned this concern to Donielle, she informed me that they also have a shop (Strutdaddys,) right in Roxboro that could do the install. I decided it would be worth the 5 hour drive to Roxboro. The crew at Strutdaddys led by Andrew and Matt got me in and out the same day and the car rides like new.
I hope the management at Strutmasters appreciates how great an employee they have in Donielle. I highly recommend Strutmasters!

I researched my options thoroughly and am thrilled with my decision to go with the complete suspension conversion kit – removing the airmatic system. The Strutmasters employees on the phone were extremely helpful. Now that the kit is installed, my GL450 rides better than ever and as my mechanic says…”I will never have to deal with suspension problems again.” My only regret is that replaced one front airstrut about 6 months before learning about Strutmasters – that repair alone cost me about 75% of what I incurred in total for the complete suspension conversion (parts and labor). Very happy with my results using Strutmasters.
