Adjustable Shocks for the Mercedes-Benz G-Class by Öhlins
Ohlin s and Thor springs for 2003 G55
Posted by Adam on 25th Dec 2017
Let me start by saying this. I have owned my 2003 G55 since September of 2003. I bought it with 7k miles and it has 55k on it now. Although I have used it, the low miles signify it’s relatively light use. I have driven it regularly on the beach/sand but never any signifant rock crawling/off-roading. The ride has always been incredibly stiff. More so because 2003, being the first year of the AMG G55 in the states, they used extremely stiff springs. From the day I had it, going over bumps was jarring and there was a clunk that came out of the back since day one. The dealer changed out the shocks and springs twice to no avail.
The day I got my truck back (after many months of waiting ) I was literally blown away. After 14 years, it was another vehicle. The ride was plush yet firm. The handling seemed enhanced, even with the 50mm lift. This upgrade is not only a nice to have item, it’s a necessity. It’s life changing. Not to mention the slight lift that gives the truck a subtle amount of necessary aggressiveness.
So far, zero additional ESP backlash as well.
The question I now have is this. Why hasn’t Mercedes done this type of suspension enhancement on their trucks (not including the 6x6, where these shocks come standard) or the 4x4 Squared, which I believe uses Fox dampers.
Beg borrow and steal to make this upgrade. It’s incredible. (Along with the Thor Springs)
Öhlins designed and manufactured the first shock suspension kit for the giant G63 6x6 truck. The shocks are now available for the G-Class to give you the perfect complimentary shock absorbers to go with your 40mm lift THOR Motorworks spring kit. True to Scandinavian design and quality standards, the shocks are well suited to the high quality of the Austrian/German G-Class.
This new high performing shock absorber kit based on the ORQ-series for the Mercedes Benz G500/G63/G65 and other G-class has been developed by Öhlins and Mercedes-Benz.
The ORQ 16/46 is a very versatile Off-Road damper for all kinds of rally raid vehicles, rally trucks and all-terrain vehicles. The damper has a swiveling hose, for increased flow potential and ease of mounting on the vehicle. The ORQ range is designed Off-Road and Rally Raid Cars in mind, as well as similar kinds of vehicles where this layout is suitable. The dampers are of 46 mm piston type with remote reservoirs. They have compression and rebound adjusters together with the Progressive Damping System, PDS. The damper comes with a protecting sleeve and two circlips to help prevent spring wear. The reservoir is now shorter and the compression adjuster has been redesigned.
The shocks can be very finely tuned: 35-40 clicks on rebound and 25-30 clicks on compression.
Here is an easy to understand explanation from Öhlins regarding the details of show their shocks adjust:
"Öhlins uses a bleed needle and orifice setup for their adjustable damping. Picture a bullet being pressed into the end of a straw....the cone of the bullet making contact with the opening of the straw. It effectively closes the flow of the straw off. That is click “0”, fully stiff/closed. Then imagine moving that bullet a millimeter out of the opening, allowing for a little bit of flow. That is click “2”, and so on. For the fully open setting, the bullet is so far away from the opening of the straw that the flow is completely unobstructed. Even if you moved the bullet closer to closed by a few clicks, it wouldn’t make a noticeable difference because of how much oil is flowing.
The important end of the spectrum is the stiffer end, and that is the end for which Öhlins maintains the tightest tolerances. That way, you can be sure that all of the dampers are matched; click zero is the same for all of them. The discrepancy lies on the open end of the spectrum because it doesn’t affect their functionality.
Additionally, each “click” of the adjuster is only moving the bleed needle a very small amount. So a 5 click discrepancy is only about 1mm of total movement. Considering all of the other parts that need to be dead on, that is a really good tolerance to keep.
A good starting point is 14 clicks on the compression adjuster (on the gold reservoir) and 25 clicks on the rebound adjuster (the allen bolt on the bottom of the shaft.)
Count clicks from 0, which is full stiff/closed, which is full clockwise. So, to get the dampers synchronized turn all of the adjusters full clockwise. That is click zero. Then count the clicks off and you should be good to go. There’s a way bigger difference the stiffer you go (lower clicker setting.)
Öhlins ensures that the tightest tolerances are kept at the closed end of the spectrum, where it matters."
The kit is based on the ORQ 16/46 shock absorbers with a 16 mm piston shaft in combination with a 46 mm piston. The kit has been tested by LeTech in Germany for Mercedes-Benz and all versions and models of the MB G-class. This suspension provides a longer wheel travel compared to the standard suspension which for some models might require installing longer brake hoses in the front.
Clearance between the wheels and the shock absorber reservoir must be checked. Depending on wheels and tires fitted, this may require the use of extra wheel spacers to achieve sufficient clearance. This is typically only the case with extra large tires.
