2002 Mercedes Benz SL55, 2003 Mercedes Benz SL55, 2004 Mercedes Benz SL55, 2005 Mercedes SL55, 2006 Mercedes Benz SL55, 2007 Mercedes Benz SL55, 2008 Mercedes Benz SL55, 2009 Mercedes Benz SL55, 2010 Mercedes Benz SL55, 2011 Mercedes Benz SL55, 2012 Mercedes Benz SL55

2002-2012 Mercedes SL55 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 a perch for a metal coil spring, which helps support the weight of the vehicle. The struts on this vehicle are considered "active" because they can be adjusted hundreds of times a minutes electronically. Much like a shock absorber, the strut dampens vibration and bouncing caused by travel on rough road surfaces. 2002-2012 Mercedes SL55 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.

2002-2012 Mercedes SL55 Hydraulic Lines- Lines that carry fluid from a hydraulic pump to the vehicle"s active struts in order to adjust the height of the vehicle.

2002-2012 Mercedes SL55 Hydraulic Pump- A mechanical pump that delivers hydraulic fluid to the active suspension components. The pump can burn up prematurely when leaks in the suspension system cause fluid levels to get too low.

2002-2012 Mercedes SL55 Suspension Control Module- A computer responsible for the operations of the active hydraulic suspension system and maintaining the vehicle"s correct ride height.

2002-2012 Mercedes SL55 Rubber O-rings- Although they are the least expensive parts of the system, they are responsible for maintaining the seal where all of the hydraulic fluid lines connect. Bad Rubber O-rings cause leaks in the system and leads to part failures.

Look for these indicators that the factory active suspension system in the 2002-2012 Mercedes-Benz SL55 is going bad: A sudden loss of three to five inches of ride height in either the front, rear or entire vehicle. A suspension warning light, at times with a chiming noise, is another sign. Sudden loss of power steering is another indicator of a problem. Vehicle owners can check for extremely low fluid levels in the hydraulic reservoir/pump; leaks around the struts themselves; or leaks at connection points in the hydraulic fluid lines. Experienced technicians tell us that when one major component of the system has failed, the others are right behind it. A complete overhaul of the factory suspension system on this vehicle can cost in the $9,000 to $11,000 range with Original Equipment parts and labor at the dealer. The high cost of suspension repairs on the SL55 is exactly why the Strutmasters suspension conversion kit is such a popular alternative.

When one component of the "Active Body Control" hydraulic suspension suspension system goes bad, the rest of the system follows suit. This is no different for the 2002-2012 Mercedes-Benz SL55. Strutmasters built its active hydraulic suspension conversion system to save SL55 owners time, frustration, and money versus a factory system that fails over and over. Our product is manufactured in the USA and comes complete with one custom-designed suspension light fix module and four pre-assembled coil over struts that bolt right in place of the factory components. Customers appreciate the detailed instructions and online installation videos that guide the repair. If further assistance is needed, Strutmasters" technicians are available to answer questions and provide support. We use dual-action premium coil springs which eliminate the need of installing aftermarket anti-sway bars -- a time savings of more than 10 labor hours alone! Our conversion system allows Mercedes owners to enjoy these wonderful vehicles for many more years WITHOUT spending a fortune!

When the wheel speed sensor alerts the ABS that the wheels are moving at different speeds, a hydraulic valve is responsible for releasing, or increasing, the brake fluid pressure to prevent the wheels from losing traction with the ground. Like all pumps and valves, those connected to the ABS are liable to become damaged and unresponsive. This may be due to internal wear typically from dirty brake fluid.

The pressure for the Mercedes Benz ABC system and for the power steering is supplied by one ABC pump, also called a tandem pump. Two pump systems are integrated within the ABC pump, and although the two pumps share the same housing, they are separate components and it is possible that the ABC part of the pump fails, but that the power steering part of the pump is fully functional and vice versa. However, if a part fails, the complete pump must be replaced because it is one unit. The ABC pump can build up the required pressure up to 180 bars through its special construction. The wear of the pump depends on the driving style, the quality of the ABC oil and the purity of the ABC system, etc. A complete pump is always sold without the black pulley or without accumulator, but with a control valve (suction valve). Below you can find the various refurbished ABC pumps that we have in stock.

The new SL55 AMG uses a newly-developed, hand-built, 5.5-liter supercharged engine with more than 465 horsepower to reach 60 mph in just 4.5 seconds from rest, making it the fastest production Mercedes-Benz ever.

The SL55 AMG also provides racing-derived braking power to match the horsepower, according to Mercedes-Benz. Immense vented brake discs at each corner and calipers are engineered with what Mercedes calls the industry"s first electronic braking system.

Similarly, the SL55 AMG uses a further evolution of Mercedes" ABC active suspension to imbue the car with quick handling reflexes while simultaneously offering ride comfort, according to the German car manufacturer.

The new SL55 AMG will be the latest in the SL line, which began in 1954 with the legendary "Gullwing" 300SL. The 2003 Mercedes-Benz SL55 AMG boasts ABC active suspension and ESP stability control, plus what Mercedes calls the world"s first electronic brake system. The new SL55 AMG is capped by a retractable hardtop, giving it characteristics of both a convertible and a coupe.

Visually, the SL55 AMG employs aggressive looks with sculpted rocker panels and rear valence capped off with four chrome exhaust tips and generous 5-spoke, 18-inch forged alloy wheels. The SL55 AMG also tours the world as the Formula 1 Safety Car.

Each SL55 AMG engine produces 465-plus hp and an impressive 516 lbs.-ft. of torque, making easy work of the 0-60 mph sprint in just 4.5 seconds. Every new SL55 AMG"s 5.5-liter, supercharged and intercooled V8 engine is hand-assembled one at a time by expert technicians at Mercedes-AMG in Affalterbach, Germany and is bench-tested to ensure performance, according to the manufacturer.

The SL55 AMG"s prodigious torque requires a high-capacity five-speed automatic transmission with SpeedShift programming that nets 35-percent quicker gear changes, according to Mercedes. Those changes can also be accomplished by pressing either of the two steering-wheel mounted shift buttons - left side for downshifts and right side for upshifts.

Like all Mercedes-Benz cars, the SL55 AMG uses ESP stability control to prevent skids and spins in poor weather driving. However, due to the SL55 AMG"s high performance, ESP is programmed specifically for the model, with the high power, handling grip, dynamics and braking performance all playing a crucial role its new programming, Mercedes said.

The new SL55 AMG"s chassis uses a fully independent, double A-arm front suspension and Mercedes-Benz" patented five-link rear suspension. The latter is mated to a substantial steel subframe that takes the place of the SL500"s aluminum subframe due to the SL55 AMG"s astounding performance levels.

Most importantly, the active suspension is Mercedes" system that it says virtually eliminates body roll in cornering, squat under acceleration and dive during braking. The SL55 AMG uses new software programming specific to the model, loosely akin to increasing the spring rates, shock damping and anti-roll bar stiffness of a conventional suspension.

Mercedes-Benz says its engineers use ABC"s interplay of hydraulic, electronic and mechanical parts to reduce body roll by 68 percent (compared to the same vehicle with a conventional suspension), providing the driver with needed feedback through the vehicle chassis. A Sport switch on the center console can alter this, further limiting roll to 95 percent reduced along with tighter shock damping, if the driver prefers sportier handling.

The active suspension system uses four hydraulic servos (or pistons), one on top of each steel coil spring, applying additional forces in response to split-second signals from the ABC computers. Put simply, active suspension solves the traditional old tradeoff between ride comfort and handling precision. The result, according to Mercedes, is that the SL55 AMG exhibits excellent comfort while offering league-leading handling.

Because of the SL55 AMG"s performance potential, Mercedes-AMG says it fits unique braking hardware to the new sportster. All the brake rotors - not just the fronts - are fully vented, and the front rotors measure a large 14.2 inches in diameter, while the rear rotors are 13 inches.

Clamping onto those generous discs are eight-piston front calipers, a direct result of Mercedes-AMG"s Championship-repeating Touring Car racing program. Mercedes-Benz, the company that invented ABS anti-lock brakes, traction control and ESP stability control, also offers what it calls the world"s first electronic brake system to see production on SL500s, and also on next fall"s SL55 AMG. This system provides faster, more sure-footed brake response, especially in emergencies.

The brake pedal works with a computer that tells four fast-acting valves exactly how hard to apply the brakes on each wheel. A backup hydraulic master cylinder comes into play only if there"s a serious problem or electrical failure. The system can change brake pressure on each wheel over uneven surfaces and can even increase brake pressure on just the outside wheels when braking in turns, taking advantage of the higher loading during cornering. Even ABS anti-lock and ESP stability control work more efficiently since they are more deeply integrated with the brakes, instead of functioning as parallel systems.

At the push of a button, the new SL55 AMG"s retractable hardtop can be fully opened or closed in 16 seconds. As the power roof retracts, the rear window glass "spoons" the stowed roof panel, providing a surprisingly large cargo area of 8.3 cubic feet. With the top up, the trunk holds 11.2 cubic feet. A hydraulic pump and 11 computer-controlled hydraulic cylinders power the system, and top operation is controlled by a switch on the center console.

Top Hydraulics" cylinder rebuild service is widely known as the best possible option, even if you are an excellent Do-It-Yourselfer. Note also our rebuild service for hydraulic valve blocks, distributors, and pumps, as well as manufacture new, superior hydraulic hoses.

Model years 1990-1996 have twelve hydraulic cylinders, while 1997-2002 models have eleven hydraulic cylinders that move and lock the roadster soft top. (The left tonneau cover lock was omitted after 1996.) The original seals in the hydraulic cylinders, aka rams or actuators, will eventually fail in every R129, unless it gets wrecked prematurely, even if you never drive the car or have never used the top before. Rebuilding these cylinders is NOT a matter of changing o-rings. Every R129 cylinder has one o-ring, and those rarely ever fail. What fails most frequently, are the other seals, which have special shapes for proper function.

2) Piston seals. They seal the input and output sections from each other, as the piston slides through the cylinder. The piston seals have been made of different materials and sizes even in the same p/n cylinders throughout the years. Failing piston seals will cause internal leaks, which result in a pressure drop in your hydraulic system. Early model years have the added problem that the piston seals swell up and make it very hard to move the piston inside the cylinder. Crumbling piston seals can block valves or pinholes inside the hydraulic system, and it can be difficult to diagnose a piston seal failure without testing several cylinders once you find that your top is moving slowly or not at all.

4) Port seals. They seal the hydraulic lines where they are pushed into the cylinders. Port seal failure is becoming more and more common as the R129s age. It also applies to the front distributor p/n 1298000022. Port seals have a special shape that makes them seal under pressure. O-rings wouldn"t do the trick. They are secured by precisely machined brass rings (accuracy about 1/100 mm). DIY removal of the brass rings will almost certainly destroy the brass rings. Top Hydraulics installs port seals that are tighter than the originals, just in case the hydraulic line fittings have been scratched. Cylinders and distributors upgraded by Top Hydraulics should easily outlast your car!

For Rebuilding Your Cylinders: You must send your convertible hydraulic top cylinders to us. Once we receive your cylinders, the turn around time is up to two business days for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).

Model years 93-95 have eight hydraulic cylinders that move and lock the convertible soft top. The original seals in the hydraulic cylinders, aka rams or actuators, will eventually fail in every W124, unless it gets wrecked prematurely, even if you never drive the car or have never used the top before. Rebuilding these cylinders is NOT a matter of changing o-rings. Every W124 cylinder has one o-ring, and those rarely ever fail.

Top Hydraulics" cylinder rebuild service is widely known as the best possible option, even if you are an excellent Do-It-Yourselfer. Note also our rebuild service for hydraulic valve blocks, distributors, and pumps, as well as manufacture new, superior hydraulic hoses.

We have two order methods: Either you send in your cylinders first, or choose to "Order now with Core Exchange".  Core exchange currently available for the R171 SLK front lock cylinder, the full set cylinders, and the hydraulic pump unit. There is a $30 surcharge per cylinder for this service, PLUS a refundable deposit of $1000 for the full set. Core deposit will be refunded after we receive your old front lock cylinders back with lines attached and intact, as well the shaft not being scratched by tools. Either scratched shaft or damaged lines result in reduced core refund. Top Hydraulics manufactures replacement shafts and replacement hoses, but there is significant cost involved.

If you send your cylinders in for rebuild service, Top Hydraulics averages a 2-day turn around time. Front lock and main lift cylinders must be received with lines attached and intact. The lines on the trunk lid cylinders are detachable.

The Vario Roof hydraulic system has eight or nine actuators and/or latch cylinders (depending on model year), including the trunk"s load assist, PLUS two pawl lock cylinders and one roll bar lift cylinder. All cylinders have the hydraulic lines attached and must be shipped in that condition.

The seals in ALL these cylinders fail with time. Usually, the roof lock cylinder 2308000872 aka A 230 800 08 72 is first to leak. If you live in a hot climate and you have noticed a hydraulic leak, then having Top Hydraulics upgrade all eleven cylinders and the pump at the same time is the best choice - you will have to deal with the hydraulics only once, you save a lot of labor in the end, and the convertible top hydraulic system will outlast your car.

Top Hydraulics" rebuild service is a true upgrade, since the rebuilt cylinders will last much longer than the originals under the same conditions, and a design flaw gets eliminated from the otherwise excellent hydraulic system.

The hydraulic lines are not detachable from the cylinders. That means the cylinders have to be shipped with lines attached and intact. Top Hydraulics can replace cut lines on the cylinders, but there would be an additional charge.

The R230"s hydraulic Vario roof pump aka hydraulic unit is a complex, high-performance pump with integrated valve block, two different output pressures, high-end electronic noise suppression, and high flow rate. The upgrade service for your hydraulic top pump replaces heat sensitive parts inside the pump with re-designed, precision machined aluminum ones, improves fluid filtering, services the valve block, solenoids and check valves, upgrades electronic components, upgrades internal seals, and replaces the electric motors if needed.

Early model year vario roof pumps p/n 2308000030 and 2308000348 aka A 230 800 00 30 and A 230 800 03 48 fail very frequently at this point, and should be upgraded proactively. Top Hydraulics" service makes these high-performance pumps better than brand new ones!

The W208 CLK-Class convertibles have seven hydraulic cylinders for convertible top actuation and latching. The two aluminum latching cylinders 1298001672 and 1298000072 are usually the first ones to fail, and should be upgraded at the same time. The five black lift cylinders 2088000x72 usually follow as a second stage.

We upgrade your 2088000x72 cylinder(s) by replacing the tiny OEM rod seal with a much larger one made of superior material, and adding custom caps made of CNC machined stainless steel to accommodate these superior seals. Our seals are not sensitive to water and are resistant to most additives in hydraulic fluid. This results in a much longer service life than the standard OEM cylinders, for a fraction of the price.

Owning and driving a convertible with an automatic top is prestigious, convenient and exciting - let Top Hydraulics help you enjoy your beautiful car even more by making your convertible top system truly better than new!

These cylinders typically fail first in the rear of the cylinder. The OEM (Original Equipment Manufacturer) cylinders have front and rear caps that are sealed from the cylinder bodies with a seal material that decays over time. Top Hydraulics replaces those seals with a far superior material that is not sensitive to water and is resistant to most additives in hydraulic fluid. Our seals have a larger cross section for a superior static seal.

Top Hydraulics manufactures and installs its own precision CNC machined front caps in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics" own u-cup seals for a far more reliable seal and much longer service life. In addition, the size and geometry of Top Hydraulics" u-cups is forgiving to tiny scratches and imperfections in the cylinder rods (aka piston rods or shafts), caused during the original manufacture, during removal from the car, during installation into the car, or by impurities in the hydraulic fluid.

Top Hydraulics replaces the port seals (where the hydraulic hoses attach) and ships spares with each cylinder, in case your mechanic accidentally pinches an o-ring while installing the hydraulic hose.

Various options are available - please inquire if you do not find the exact match in our online offering. Top Hydraulics services and upgrades pumps, upgrades the seals in the cylinders, and replaces hydraulic hoses if necessary with far superior material. Why buy new parts - you will get a superior product back from Top Hydraulics at a fraction of the dealer price.

The seals inside these cylinders are similar to those in other convertibles and lift gate cylinders: they decay with time. Otherwise, the cylinders do not normally wear out (unless they are grossly mistreated and get damaged on the chromed shafts). Thus, with Top Hydraulics" superior seals in your cabriolet hydraulics, they will be better than brand new parts.

Top Hydraulics does not currently stock the G-Class convertible hydraulic cylinders p/n 463-805-00-01; you will have to send in yours for rebuild/upgrade service. Please contact Top Hydraulics if you need individual hydraulic lines/hoses/pipes manufactured, or if you need us to rebuild your convertible hydraulic pump.

Top Hydraulics is currently servicing the lift gate pump and cylinder on a case-by-case basis. Send us your pump or pump and cylinder, we will evaluate them, and give you a price for rebuild with warranty. In most cases, the rebuild cost is between $300 and $400 plus return shipping.

Most pumps fail when they accidentally get exposed to too much moisture. The rebuild service of the electrical portion of your pump can entail replacing the electric motor, replacing the solenoid, rebuilding the motor, rebuilding the solenoid, replacing the wiring harness, repairing the wiring harness, or a combination of the above. Further to electrical issues, Top Hydraulics will always rebuild the pump by replacing internal seals, replacing rotor and pistons if necessary, replacing or rebuilding internal check valves, and putting the finished product through an extensive test to ensure that you get back a pump that performs better than a brand new one.
