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 and newly manufactured OEM style replacement parts.

Suncore's Air Struts are manufactured to the Original Equipment specifications to be a perfect replacement for the faulty air strut assemblies in your vehicle. As an air spring installed over a dampener, Air Struts or shocks give you that comfortable ride while providing structural support for your vehicle and its load. Inspect and maintained your suspension at regular intervals to ensure your air suspension is working properly. When your vehicle begins to sag or isn't level, handles poorly when stopping and turning or roughly shudders at the little imperfections in the road, you should immediately have your suspension tested for leaks or damaged components. A leak in the air strut will quickly damage your air compressor as it works to keep the bellows full, stressing the compressor and overworking it.

I don't see a sport/comfort button in my 07 Mercedes Benz gl450. So this is the correct item I will be purchasing to change all the bags?

Customer Service

Hi Jerome, Correct, this is the kit you would need, If you need anything else, please feel free to let us know. - Tabby


Customer Service

Hi BNZFXR, All of our parts come with a 1 year warranty. Have a great day. -Tabby

After the vehicle is not driven after a few days, the vehicle lowers in the front. When snowing, the rear of the vehicle lowers while driving. But will raise to normal ride height after it warms up. Rear bags were replaced within last year. However nothing else has been replaced since then. Would be advisable to replace everything?

Customer Service

Nathan, Thank you for providing the details on this situation. During the winter time its common for air suspension parts to freeze up; that delays the response time to fill your air springs. I recommend checking the air compressor by performing a bench test. You may need to replace just the compressor. I hope this information helped, I do apologize for the delayed response. Have a great day! -Stephanie
