Mercedes-Benz S Class W221 Left Rear Air Suspension Shock

Your Mercedes-Benz S Class exemplifies everything great about luxury cars. It’s cozy and cool on the inside, while its motor is more than capable of getting you up and going when you’re craving some speed. But the instant those air struts go faulty, you’ll wonder how this car ever received its luxury status. Even trips down smooth highways become a bumpy mess. And all that power under the hood seems abysmal. Fix all these issues by ordering your Mercedes S Class W221 rear left air strut online through AEROSUS.

Does Your Mercedes-Benz S Class Need Air Struts?

Well, do you enjoy smooth, sporty, and safe rides? If you do, then the answer is a clear S.

Your air struts consist of an air spring and a shock absorber to provide you with some of the best drives you’ll ever experience. Here’s a quick list of some of the benefits air struts bring to you:
• Corner at high speeds with full control
• Slam on your brakes while maintaining control
• Dampen vibrations on rocky roads for a smooth ride
• Get the height you need to cross over potholes and curbs with ease
• Carry heavy loads

How Will You Know When It’s Time to Replace Your Air Struts?
Your Mercedes-Benz lets you know when your air struts are suffering with the following signs:
• Sagging to a corner when parked
• Fluid/ oil leaks when parked
• Rough and uncomfortable rides
• Lower ride height than normal
• Thumping and clanking noises coming from you shocks
• Your air compressor runs non-stop


The actual cause for air strut damage varies. Anything from air spring leaks to faults with your dampers can act as culprits.

When you notice damage, make your replacement ASAP. With no action, your air compressor will burn out trying to compensate for your air struts lack of work.

Worst-case-scenario, you’ll lose control on the road. And when that happens on a highway or at a busy intersection, your safety’s at risk.
