What is it?
Air springs are heavy duty torsion bars coiled around an axis which compress and expand to absorb motion of the wheels.They are used in car suspension systems and are they are considered more efficient in vibration isolation than steel springs. Air springs are useful to the air suspension system of a vehicle as they offer a smooth ride and they assist in leveling.
The rubber that the air springs are made out of is very tough, but it can wear out for a number of reasons. It can be susceptible to damage from moisture. Extremes of hot and cold can also damage the rubber. Drivers in hot or cold climates are more likely to experience air spring failures than those in mild climates. The rubber could also be punctured by road debris.
Any of these problems can cause the air spring to leak air which will make the suspension sag causing the vehicle to sit uneven or, if the leak is sever enough, the vehicle may not reach proper ride height.
Customers can find the product you need accurately according to the OE part number. This is a compatible replacement part manufactured our factory. Associated vehicle models and part numbers are used in this listing only to identify the vehicles this air spring fits.

I was skeptial at first but decided to give it a try due to the significant cost savings.All parts and fittings were included in the box.It takes a 10mm wrench to connect the airline.The installation was easy and it went very well.The bags were stiff at first and vehicle was higher than normal but they settled in a couple of days.

Installed these two air bags on my GL450. The next day drove for an hour and a half with four people in the car and a few suitcases. The shock blew apart and nearly caused a loss of control. This is a very dangerous inferior quality part that appears correct, but is made of substantially lower quality rubber than the original part. You cannot tell until it fails. Do not risk i buying this garbage! It cost me thousands to get the car fixed when it broke down on the side of the road instead of the few hundred dollars good parts would have cost me when I did the job myself.

We are reviewing this company based on their customer service. The first set of air bags were defective. The representative from TOPS, responded, and sent out two new airbags promptly. Thanks again for everything.

3 stars because one was defective from initial purchase. It has been over a month and I still do not have a replacement. Other than the defect, the product itself is fine.

overall the part was good. I was not Able to use the airline fittings that came with the shocks they were too tight. I ended up sourcing the fittings from Mercedes directly eight dollars apiece nothing major and after that they worked perfect. I installed this on a 2014 GL 450

Great value since Mercedes ones were over $1000 for a pair! Mechanics who installed them said they were a good product.

Though website said not compatible for 2017 GLS-450 rear Air spring but it worked. I did research on several websites for best fit for this vehicle. Found this at much less cost. Took a chance and here you go. The quality of these Air spring appears good. Hope it holds up for long. The installation was super smooth. All you need to do is, remove the wheel followed by removing air hose connector on Air spring using 10MM combination wrench.
