My customer has purchased three sets of the conversion kits so far, and every one of them has been excellent. Easy install and the module for turning off the dash warning light has worked every time! I highly recommend these kits to save money over replacing expensive refurbished air struts as a long term solution to a potentially expensive repair. Zero complaints from my customers with the three kits I have purchased so far!

Why Choose Strutmasters
Why Choose Strutmasters
The SL500 active hydraulic suspension is one of the most complicated and expensive suspensions ever offered in a vehicle sold in North America. The Strutmasters suspension conversion system allows SL500 owners the ability to bypass all the electronics and eliminate the headaches caused by the factory suspension system once and for all. The Strutmasters kit uses variable-rate coil springs that deliver great ride quality and eliminate the need to purchase "anti-sway" bars that can take up to 15 labor hours to install with other products on the market. Designed and assembled by hand in small batches in the USA, this kit comes complete with one custom-designed suspension light fix module and four completely pre-assembled coilover struts. Customers appreciate our detailed instructions and online installation videos to assist with their repair. If further help is needed, Strutmasters' technicians are available to answer any questions. If that isn't enough, the quality parts are backed by our 1-year warranty. Compared to direct replacement at the dealership and individual part replacement, this kit can save SL500 vehicle owners up to $7000 in parts and labor costs.

Replaced Components
The 2003-2006 Mercedes SL500 is built with the following suspension components:
2003-2006 Mercedes SL500 Active Hydraulic Struts (x4) - A long tube (similar to a shock absorber) that fills with hydraulic fluid forced in at varying rates of pressure determined by sensors on the vehicle. The strut is the resting place for a steel coil spring, which works to help support the weight of the vehicle. The struts are known as "active" because they can be adjusted hundreds of times a minute electronically. Much like a shock absorber, the strut dampens vibration and bouncing caused by travel on rough road surfaces.
2003-2006 Mercedes SL500 Height Sensors (x4) - A linkage located near each wheel of a vehicle that electronically measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.
2003-2006 Mercedes SL500 Hydraulic Lines - Tubes that carry hydraulic fluid from a pump to each strut at a high rate of pressure.
2003-2006 Mercedes SL500 Hydraulic Pump - A mechanical pump that delivers hydraulic fluid throughout the system at a high rate of pressure. On many models, the pump may have a second reservoir that works to deliver power steering to the vehicle. The pump can fail due to normal wear and tear OR it can burn up due to low fluid level caused by leaks in the suspension system.
2003-2006 Mercedes SL500 Suspension Control Module - A computer that is responsible for the operation of the active suspension system and maintaining the vehicle's correct ride height.
2003-2006 Mercedes SL500 Rubber O-rings - Although they are the least expensive part of the air suspension, they are responsible for maintaining the seal where all of the hydraulic lines connect. Be sure to replace the O-rings when repairing any active suspension system.
Suspension Failure Signs
A sudden loss of three to five inches of ride height on any or all of the four wheels is the most obvious sign of a problem on the 2003-2006 Mercedes-Benz SL500. Early detection of a bad suspension is the key to avoiding total failure. Check for hydraulic fluid leaking from the struts, lines, connection points or the pump itself. If the fluid level gets too low, it can burn out the pump and lead to a widespread failure of the system. A sudden loss of power steering and you'll know the pump has most likely failed. A suspension warning light, at times accompanied by a chiming noise, is another sign of trouble. And because this system is so complicated, replacing just ONE part will seldom solve the problem. Many experienced technicians will recommend replacing ALL of the major components of the factory suspension to have a high rate of success. This type of complete repair can be in the neighborhood of $9,000 to $11,000!

Customer Reviews
Overall rating: 4.6 / 5 from 67 reviews.
Mechanic had no problem with the install. Ride is a little stiffer than I thought it would be. ( that’s the only reason for the 4 stars And not 5 ) Need to drive it more to know for sure. Delivery time was very good. Never have to worry about hydraulic suspension leaks again.
Fast Shipping, Great Communication.
coil over kit worked great. technical support was also spot on.
The missing component would be the power steering pump for the single pump system VS the dual pump system. The system was installed with no problems and appears to working well
Great fix for the pesky ABC problematic system
You provide the best quality the service is wonderful and the delivery is always accurate. Representative was very helpful! Thank you for all you do.
As always,a great fix and no installation issues! Thanks for a great product!!
So far so good. Missing a male plug. Will have to call customer service
Good fit.
Other than FedEx fucking my on delivery. Product is great installed. Feels like I'm still riding on the ABC system. Instructions were very detailed and easy to understand
Quality parts and detailed instructions for your vehicles install. No issues.
your best
Transaction was pleasant .
The instructions were spot on, made the installation less complicated than expected and made the height great
Perfect!!!
Great conversion kit and friendly staff
BOLTED IN GOOD RIDES GOOD
Great service big help. Thanks
Just got the car back from the mechanic, so far the ride is great. The shipping of the parts directly to the shop made the whole process painless for me. Need more miles to evaluate how the struts perform.
TIMELY SHIPPING, FITMENT WAS PERFECT! NO WARNING LIGHTS. SMOOTH RIDE AND PERFECT RIDE HIGHTH. THANK YOU
It sits a little high in the front, okay quality
.
Hardest part of this kit is removing all the old junk from the hydraulic system. An option for Springs with a different ride height would be nice I think it sits up too high in the front now. I'm hoping with a few more miles things will settle down otherwise it was a very good experience and I would highly recommend it to anyone who has a Mercedes with the old hydraulic disaster system in it.
The struts were installed , currently it’s a very stiff ride and when I go over a bump , it’s not a comfortable feeling and very hard to the point where everything rattles. For the money spent, I thought it would provide a lot better ride. Certainly not even close to orginal Mercedes factory system. Very disappointed and felt like I wasted my money, car is t the same anymore. If I had to do it all over again , I would have fix the air suspension system instead.
Great ride and no ABC headache in the future.
Back was a butt to install. Front was easy.! Ride is nice. But no more headache and worry about the car being on the ground!
product was advertised made in usa but it was made in china it sqeaks very loud and now the car feels like a tunaboat i filed a complaint with bbb to get a full refund and you ignored it so dont be surprised when you see the sheriff come to serve you...i'm taking you to court for fraud and now you're gonna pay back the full amount plus round trip from california to your redneck town plus instalation an removal plus court fees plus lodging,taxiplus incovenience...and after that i'll go for criminal charges
KIT HAS GREAT FITMENT. ADAPTER PLATES HELP MAKE SURE THE CAR IS LEVEL. USED ONE SET OF ADAPTER PLATES IN REAR AND NONE IN THE FRONT. COULD OF PROBABLY INSTALLED BOTH PLATES FOR A PERFECT LEVEL HEIGHT
The kit came very fast, but I am having trouble getting a shop to install it. Although I am a mechanic, I am retired and not as strong as I used to be, this might be a winter project
I had trouble making the decision what strut to use, use StrutMasters or a different brand. Different brand a little cheaper, but no one to talk with. After talking with Tammy a few times, I decided to go with StrutMasters. It was a good choice! My concerns were installation and the level the car sits. Let's start with the level the car sits. I'm satisfied. Not perfect the way I might like, but pretty close. I'm also satisfied with the ride and handling. My wife also said it was good. Now for the installation, I did it on jack stands, would have been a lot easier on a lift. I was a little intimidated to do this, but I did it. Also did the by-pass kit for power steering. I had a few questions during power steering by-pass and ABC light electric module. Jeff in Tech Support helped with instructions and mental support. After all was complete, it was just as Tammy said during purchasing the instructions and tech support will get you through. Thanks for your product, customer service and tech support. You have a satisfied customer. I did it and you can too. Believe in yourself.
Great product
Great way to save money. The difference between the two are quite negligible. Can I stiffen them up by turning the nob at the top. Also I've lost the module to eliminate the sign on the dash. Can you please send me another. Cheers
Absolutely love it ! My car is smoother than when I bought it! Thank you very much! Bob Renneke
It worked out great. If you know anything about mercedes rear suspension it was a fair bit of work. They give fairly good instructions on how to do the job. You will need a rear end alignment when you're done with the job. I would say the ride is closer to the sport feel with the height of the high setting of the original hydraulic suspension. The module to reprogram the dash light for the suspension seems daunting but it's pretty straight forward. They might be a little more expensive than some brands but they're all USA made and very high quality parts. The customer service is USA based as well. I would recommend them to anyone.
La livraison s'est fait très très vite! j'ai commandé le lundi et le jeudi le produit était déjà livré. J'en suis très reconnaissante parce que je ne pouvais pas utiliser mon auto et 2 jours après c'était réparé et maintenant je l'utilise. Un immense merci à vous!
Very nicely thought out! you guy or gals rock the industry thank you
I still cannot install the 2 rear coilovers. Been a week trying to get the trough that the ABC strut is down in.... to separate from the hub. All the bolts are out, but No luck prying on this thing to get it separated. This is an SL 600 , Lorinser package auto, but everything disassembled the same . Sooooo, frustrated at best.
The car drives unbelievable. I mean it feels better than brand new and the suspension is like riding on a magic carpet ride
It makes the car handle better, tighter, more direct, without being hard and uncomfortable like a sportscar. We build as a shop about one to two a month in and I never had customer complaints. On the cars with hydraulic we usually replace the double pump with a standard steering pump for the steering and take best as possible everything that was belonging to the hydraulic suspension out. I think that is the way to go when the air ride or the hydraulics are getting old and start failing.
