New Coil Spring Conversion Kit for 2000-2006 (W220 w/ AIRMATIC, wo/ 4MATIC) S-CLASS

Just thought this was interesting. Arnott is making a coil spring kit that seems to be very legit. There was another coil spring kit out there from Strutmaster but it seemed a bit shady with the lack of pertinent information.
Check out Arnott's conversion kit here:

I'd trust Arnott's products. I've bought my X5 air strut from them before and my mechanic was impressed with the quality.

Though with the relatively low cost of air suspension parts for the W220, I'd personally just stick with the comfortable airmatic ride than do the conversion.

I have to say that the Sport 2 Mode with the Arnott struts delivered much better handling than the OEM struts. I've driven in comfrot mode the last 3 years on my car and just 2 days ago tested sport 2 and it makes the car feel like a 3K pound car and not a tank anymore. I'm hooked on it

Sport 2 is extremely fun!! But it is also harder on your struts so be careful for potholes! I am wondering how stiff these coilovers are gonna be from Arnott, I would love to drive on a set and compare to sport 1/2

Adam from Arnotts said that this new conversion kit has been tuned to ride like oem. They teamed up with bilstein engineers to make and tune the kit... he said the ride is phenomenal. Arnotts is a member at benzworld, check em out. Goodluck.

I am really thinking about this kit because I THINK I have some pre-warning signs of failure. My airmatic visit workshop warning is on but its been on for months now, even though the car's airmatic works fantastic. Sometimes the driver side rear is a little bit lower than usual. We'll see how that goes, not to sure of the problem...

As for pricing for it, I am guessing it will be more expensive than buying 4 struts from Arnott since (Im assuming) it is a great fix to a very expensive problem.

Mbniko how many miles on your vehicle? If its operating fine , I would not worry. Rear strut are rare to failure. Front airmatic struts were a problem. Get the car inspected from whomever you use for maintenance .... hoping that they know Benz or the dealer? And see what they say about the rear. I'm sure it would be costly to buy new conversion and pay for labor to install it. Arnotts has reman air struts that are far better than oem for dirt cheap. I'm not going to hate on ya but just FYI there are others on this forum that will attack and say keep airmatic , conversion is junk. I personally would just replace what's wrong with it and keep airmatic if its functioning properly. Goodluck.

I have a little bit over 91k on the car. It really does operate fine. 2 times the STOP CAR TOO LOW in red came on and I stopped and took a look at the wheel well clearance of all the wheels and they were all perfectly fine!

I wouldnt actually get this kit just because of one strut though! My issues with airmatic dont seem too critical at the moment. I go to Fluid Motor Union for maintenance, Ill have to go soon for service B so we'll check out the airmatic system too.

Which is why I said that the relatively low cost and easy maintenance of the airmatic system doesn't justify replacing the entire system with coils, especially with the lack of adjustability with the coils.

For the BMW X5 however...that's a different story.

AMEN! They need a ABC conversion BADLY. Nobody can afford to keep an old ABC system up to par on an older MB its just not cost effective.

Hey guys pricing came out over the weekend! Much to my surprise it's listed at $1395 I believe. Not a bad price if your airmatic is really screwy lol this also includes hardware to wipe away any airmatic error codes.

Not bad... but let's see...

~$950 for new airmatic fronts from Arnott
~$600 for new rears
~$350 for new pump
~$350 for new valve block

=~$2250...and the entire system is new, you retain comfort and adjustability.

It's a tough call.

Saying that someone has enough money to choose the conversion option or just replace the airmatic.... I would definitely just install the airmatic system again-saying its all fried/deflated. The fact that Arnott has a lifetime warranty on their items can make MOST people rest easy haha I really enjoy choosing between comfort/sport 1/sport 2 instead of just having one setting like the conversion. Bottom line here is that Arnott is an awesome company

If you take it to your indy shop, hopefully they can cut you a deal. Id say to change all 4 struts would take about 5-6 hours so around $6-700 in labor depending on your shops per-hour rate
