AirRide Custom kits are bolt-on air suspension systems that allow you to control the height and ride quality of your Mercedes.

Custom kits are perfect for dropping your Mercedes right to the ground, but they also provide you with the right amount of lift to ensure your car remains practical and undamaged – it’s the ideal way to make your car both stylish and effective.

This means your Mercedes W114/115’s handling and ride quality will be maintained while you are also able to adjust the ride height at will and while driving, meaning you can avoid any obstacles on the road as they come. Most systems will offer a ride range of around five to six inches but this will vary depending on what Mercedes you have.

NOTE:- Clearances on this kit are tight. It is essential that the installer pays very close attention to ensuring that neither the front nor rear bags touch on anything. If they do then they will be damaged and this is not considered to be a warranty issue. This is an installation issue. If in doubt about installation please reach out to us (or have your installer reach out to us) and we will be happy to discuss prior to purchase or during installation.

You can also choose to include an air management system of your choosing. This allows you to get the very best from your air and adjust your ride height while on the move. See the ‘Management Options’ tab for more info.

Last but not least, each Custom kit from AirRide, with air management, also includes a VIAIR 444C compressor or equivalent. The compressor is integral to the smooth running of your air suspension and the 444C allows you to run your system as much as you want at high pressures. It is compact too, so is easily stored on any Mercedes.

Here’s exactly what you get in your kit:

  • Four Mercedes performance air suspension brackets
  • Rear Mercedes performance air suspension brackets
  • Four air springs/ bags, one for each corner
  • Necessary bolts and fittings to install the system

Most of our Mercedes kits do not include new dampers because of the design of the suspension on these vehicles. We always advise new dampers unless your vehicle is very new or has just had them replaced. Whilst the market is dominated by low cost gas assisted shocks/dampers, Mercedes almost always perform better will hydraulic oil based shocks. Air suspension conversions always do when such dampers are available.

You can also add an air management system if you wish. To get the most from an AirRide Custom kit a control system is recommended. With a management system you also get:

  • An air tank, if needed
  • Viair 444C compressor or equivalent

If your system needs are not met or if you have questions, please don’t hesitate to email or call us on 0800 772 0315.

About AirRide Custom

We’ve been making Mercedes kits at AirRide for more than 15 years. In that time, we’ve honed all our kits to make them the best, most comfortable air suspension kits on the market.

Custom kits are ideal if you want to drop your Merc extra low, as you can fabricate your struts to give the exact ride height you want.

Management Options

AirRide Custom kits can be supplied with or without air control (otherwise known as air management or On-Board Air (OBA)).

Air control allows you to get the very best from your kit at all times. It allows the ride height to be adjusted for road, weather and load conditions, and for those who experience grounding issues it allows the absolute maximum lift to be achieved when needed (i.e. for ferries, petrol stations and rough site entrances). If in doubt, please contact us via email or phone.

No compressor, no tank

You can have an AirRide Custom kit with no air control system but this is not recommended. With this option you will receive the air bags, brackets and struts required for a basic air suspension system, but no compressor or tank, as without some form of control system the compressor and tank would not be able to function correctly.

Manual Paddle Control (MPC)

MPC comes with an aluminium, 100% duty cycle compressor with up to 200 PSI and an air tank. It is controlled with four buttons, one for each air bag. The buttons act like electric window switches, meaning you can either raise or lower the amount of pressure in each air bag by pressing up and down on each switch.

Digital computer system

The computer system comes with an aluminium 100% duty cycle compressor with up to 200 PSI and an air tank. It electronically controls the amount of pressure in each air bag. This can be controlled either with a wired controller or a phone app.  With the computer, you can adjust your car to certain pre-set heights and alter the vehicle’s height while on the move. This is also the easiest system to install; it is the most highly-recommended option.

Other options

If you would prefer an air control system other to those listed, please feel free to call or e-mail us. We are happy to discuss your personal requirements and make sure you get the air control system that is right for you.


Although this kit is specifically for the W114/115, we also offer kits for any Mercedes produced from 1968 onwards. Please feel free to call us on 0800 772 0315 or e-mail us to discuss options for your Mercedes.

One of the main benefits of AirRide Custom kits is that they are easy to fit. This means that your local garage should be able to fit the kit without much difficulty. Alternatively, call or e-mail us and we can conduct the installation for you. We are also happy to talk you or your garage through the installation process.
