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!

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.

Be wonderful if expert installers were trained by you all. It would make process that much easier great product from my experience with mechanic and product. I was Bless to find a mechanic who knew what they were doing. The mechanic was hard to come by!
Sharon B.
Had installed to take care of future issues with the hydraulic system. I'm told the ride will soften up alfter a few miles...no issues at all.
Gary O.
The struts are great nothing to worry about anymore,car handles great
Tony M.
So far it feels very good, I will know better after I drive it longer. I need to solve the issue of a slight leak on the Hydraulic pump. I will be able to give you a better report in another week or so but I do not expect any issues.

The ABC system on my 2004 SL 500 was giving me a lot of problems, components leaking etc.. very expensive to repair if you can find someone to fix it. The strutmaster system is AWESOME. I replaced it myself. Took it on a long drive today and it feels great. Thanks strutmasters.

Struts have completely changed the ride and handling of our 2003 Mercedes SL 500. We went from a noisy bumpy ride to a quiet smooth one thanks to the struts from Strutmasters…Thank you!

Really makes the car handle like it’s on rails . It’s a much greater improvement than the stock slushy ride suspension with no worries of coming outside and the car being on the ground . Why any manufacturer puts a hydraulic suspension on a car is beyond me . Thanks for the great product . Also thanks for the enclosed instructions.

Best thing your ever made and I am enjoying the ride. Thanks
David S.
The conversion kit works very well. The ride is currently a little stiff, but I've only driven less than 100 miles. Very satisfies with the results. I just wish I would have known about it sooner. Would have saved me a lot of money.
Beau C.
Great kits great price happy customers....
Reggie P.
it was a smart decision and worked out perfectly, i just wish it was a part of the kit. This is a must-have when converting to the Strutmaster system
Reggie P.
This kit is awesome and was pretty easy to install. It comes with everything you need and the support from Strutmasters is second to none. This was something I should have done a long time ago when my first hydraulic strut went out and it cost me just as much as the entire conversion kit to replace. BTW, my SL500 rides much better with the Strutmaster system.
Marc S.
ITS A BETTER RIDE THAN THE AIR SUSPENSION!!!
Louis N.
I replaced my Mercedes SL500 ABC system with Strutmasters [cost $3000 labor and Strutmaster Springs] instead of replacing only two rear rebuilt units @ $4000. Car rides as well, if not better than the original ABC system.
John G.
The module and bypass hose is a big plus in the kit eliminating all that hydraulics and warning lights. I can honestly say the ride is equal to the Mercedes system I don’t see a difference I’m happy with the suspension thank you
Helen W.
Haven't driven it yet, but do have a question about the ABC indicator not going off still, however it is no longer showing in red anymore. I know we hooked the wires as instructed.
Robert O.
Great experience After getting the new suspension put on Drive great and field Better than it did The stock suspension

car runs good now

The installation was easy enough and the vehicle looked and drove perfect. I only had one question regarding the by-pass of the Suspension ECU, and the customer service was exceptional.
