WARNING CA Proposition 65
Suncores Coil Spring Conversion Kit is designed to be a cost effective replacement for the components of your air suspension while keeping your vehicle at its designed factory height. Our powder coated coil springs are manufactured to be long lasting and rust resistant, while at a much lower price tag than conventional air suspension components. With our air to coil spring conversion kit, you can replace just the front, rear or both segments of your suspension quickly and easily, saving yourself the hassles and headaches of a faulty air suspension.


Suncore Industries was established in 2000 and have been a member of the Automotive Parts Rebuilders Association (APRA) ever since. Our mission began with rebuilding air suspension components and moved quickly into offering better solutions with conventional suspension conversion kits to give our customers the longevity they can rely on.

The most common reason for an air strut failure is due to dry rotting of the air bag. This is something that happens over time, the air bag starts to deteriorate and causes leaks, when this happens the air bag can no longer hold air pressure. A leaking air bag can cause the strut it fits over to fail as well. The second factor of an air strut failure is the strut itself. The strut is pressurized with fluid, and if the strut begins to fail it will no longer have the same pressure to hold the vehicle. If this system begins to fail one visible sign will be that your vehicle will be lower than factory height. If Air Struts are not replaced on time, it will cause an Air Suspension Compressor Failure.

Front Air to Coil Spring Suspension Conversion Kit - Mercedes E Class W211 RWD

Hi Sales / customer service Need to enquire if your w221 mercedes air to coil front set will fit a 2006 cls500 as stipulated on your website. I need to bring the set South Africa but need to make sure its a fit. Your assistance will be grealy appreciated Kind regards Jose

Customer Service

Hello, Yes this is the correct kit for your 06 CLS500 as long as the vehicle is not a 4matic model these will fit and work in the factory mounting locations with no alteration Thank you

Is this part #127M-31-F correct for 2003 Mercedes Benz e500 Read wheel drive?

Customer Service

Hello! Yes the 127M-31-F will be compatible with your 2003 E500 RWD. These front struts will eliminate your current electronic air suspension and replace it with a passive conventional suspension. This conversion is one of our more popular parts.

Hi, Does the kit include instructions on how to disable the electronic components and warning lights after converting to conventional suspension?

Customer Service

Hello, We appreciate your question regarding conversion. This kit requires a Star Scanner to disable your air suspension system, unfortunately we do not provide a module. Our instructions do not include steps to bypass the light, you will have to take your vehicle to a Mercedes specialist shop or dealer to disable your air suspension. Please let us know if you have further questions regarding this kit. Have a great day. -Stephanie

Do you make air to coil front set for 07 e350 4matic?

Customer Service

Hi David, At this time we do not offer conversion parts for a 4 matic model; we apologize for the inconvenience. These front struts will not settle evenly or give a quality ride in a 4 matic model. Please let us know if you have any further questions, we hope you have a good day. -Stephanie

What are my options for a 2006 e350 4matic front struts (conversion,refurbished,new)? Thx

Customer Service

Hi John, at this time we do not offer a conversion for a 4 Matic model, we do apologize! Your options are new and remanufactured air struts, please see the link below for compatible parts: Have a good day!

Can i just change the front to coil and leave my rear air on my e500

Customer Service

Hi Jose, Yes you can do a partial conversion on your E500. If you should have any other questions, please feel free to ask. Have a great day. - Tabby

When changing just front do have to program with star or just plug off front lines

Customer Service

Ramiro, You will need a star scanner to disable your air suspension ONLY if you are converting all 4 corners. For now you can just plug the airlines and tie them off to the side. Please let us know if you need anything else. -Stephanie

Does this work with 2006 CLS 55 amg and do you have the rear as well along with the by pass for the warning dash lights ?

Customer Service

Scott, This is compatible! The dash light has to be programmed out using a Star Scanner, however to do that you will need to convert all 4 corners. For now you will just have to plug your front airlines and tie them off to the side. Let us know if you need help with anything else. -Stephanie

When you say for a 4matic model it will not settle properly can you still buy this kit and put it on a 05 e500 4matic..i am sick of the air ride problems i just need the front raised just a little i dont care about ride quality..Just wondering will the conversion kit work for the front of a 2005 e500 4matic as far as matching up?

Does this product have adjustable dampening?

Customer Service

Thank you for reaching out, No this does not retain the active damping
