Lowered or not lowered: this is the question

[Le_Combattant]

Thanks for the explanation.

I think I will stick with original VW part

-Front axle:

-Springs: 6R0411105B (SACHS 993 067)
-Shock absorber: 6C0413031AH/6C0413031CR (SACHS 314 717)

-Rear axle:

-Springs: 6Q0511115CL
-Shock absorber: 6C0513025AJ (SACHS 317 357)

However, I'm stuck with the rear spring.

I found this very nice website where all 6R/6C parts are listed.
Rear spring 6Q0511115CL (for my rear axle load) is here: https://catalog.polo.blue/6Q0511115CL/

But there is no manufacturer information unlike spring for the front made by Sachs.
And on internet also nothing.

Some are on eBay but not so much, so it's quite strange.

However, 6Q0511115CK (the rear spring you have) is well know on internet, but the class weight is different (lighter).
-SACHS 994 453

And VW official price are...quite expensive. More than 100 euros per spring.

Just a quick note, the fact that the manufacturer's springs are indicated for VW references does not mean that they are exactly the same as those supplied by 'this' manufacturer to VW. Non-VW springs are usually more generic, that is, they usually have a wider range of use... and this influences the final height and comfort once installed.
You know, then there may be discussions, speculations, interpretations, or feelings different from what was established/discussed.

And since Sachs is not providinf any data sheet, it's hard to know if they are like the same as those one selled by VW.
400 euros just for the spring, RIP my bank account

Concerning the shock absorber, what is your point of view ?
VW or Sachs ?

You think a difference may existe even they have "the same part number", or equivalent's one ?

[ciclo]

I have no experience with non-VW shock absorbers, I only have experience with non-VW springs.

I recently installed the entire DCC suspension on our Golf, and the only non-VW parts were the front springs, Monroe brand, just like the original VW factory springs. I couldn't be happier to have done it, apart from the great improvement that the DCC suspension represents, now all the settings are millimetrically perfect on both sides and the car feels on rails even in those tight turns/curves that are considered highly dangerous (you know, where to get through a curve at a certain speed you have to mandatory to drift ).

The original VW springs had a small 'factory defect', the front left spring was not the same length as the right one once removed, -4mm difference, but due to the factory settings on the front suspension it was not noticeable.
I took measurements before removing them and I could already see this difference, but I thought it was due to the uneven ground or that I had not balanced the body enough before taking the measurements.

Just seeing as you added comments about your Golf, I think that the factory fit DCC dampers are Monroe, that info is from many SEAT Leon Cupra owners needing to replace their leaking from dampers at maybe the 5 year point in the car's life, my older daughter's 2019 SEAT Leon Cupra had weeping front dampers from 3 years old onwards, now I consider that one side, the LHS front damper is leaking and needs replacing, I plan to buy two Monroe DCC dampers for it as they are a lot cheaper than the same item from VW Group.

[ciclo]

This is what the original factory shock absorbers -Monroe- on our Golf looked like after 6 Years 5 Months 4 Weeks 2 Days when swapping them for the DCC suspension.

I didn't notice any seepage/oozing on either of them, I cleaned them and everything looked in normal condition.

For normal use (not specific for large tunings) I see it very good to install the same brand and specification as the originals.

monroe oem ?

Realistically, does that matter nowadays?
Offshoring of production and other factors such as optimising the profitability of selling commonly used products (that which CEOs wrongly do to justify their salaries) make it impossible to know which products end up being good or bad in terms of quality...

Nothing is permanent nowadays...
For example, what do you think about the good reputation that the VW group had before compared to today?

My factory Monroe shock absorbers were/are EXCELLENT in every way... in my opinion they could be used for many more years. I only changed them for the sake of having fun installing the DCC suspension on the Golf. Without a doubt, I bought original VW DCC shock absorbers from the Monroe brand again... and so far I can only say that they are great!

20 years ago I would not have installed Monroe under any circumstances...

[amer6R]

Great job Monroe for the excellent quality!
They probably gave a better offer and got the job.

I just think that people's care should take better care of the people.

[ciclo]

I don't know the ins and outs of the VW group's business relationships with other companies.
I totally agree with you, those who make a profit from selling products should take better care of people/customers, ...except if you have a monopoly, and then you already can be as evil as you want.

The true POWER of a customer is NOT TO BUY...

[Le_Combattant]

So Monroe is the second brand used by VW after SACHS for shock absorber.

Very interesting.
So it may explain why so many shock absorber fail after few years on Golf 7. On a French forum dedicated to Golf 7/7.5 we have many complains about Monroe quality and failure.

[RUM4MO]

It does seem to be the front LHS DCC Monroe dampers that fail most, I think that Monroe is the only supplier that VW Group use for DCC dampers.

Hello all, hope you are doing well.

I'm sorry for the topic digging but I prefer asking now just to be sure.

Here, the current setup of my car with the dedicated PR codes:

PXL_20250608_173346041.jpg (2.33 MiB) Viewed 7451 times

Rear axle is pretty straight forward as the front one with G72 and L39 for the axle load.

Remember, my front axle max capacity is 870 kg and the rear is 800 kg.

Where I have concerne is for the front axle spring's choice, or more precisely, it's PR code about the weight "range".

For the back it's will be pretty simple as my current setup is:

-0YN
-1JP

So for the spring, I could easily swap to:

-0YN
-1JS

With for the spring, part number "6Q0511115CL", matching perfectly my rear axle load.

For the shock absorber, I could have the choice bewteen the factory one (1JP), part number "6C0513025AH"
or
the "sport" (1JS), part number "6C0513025AJ"


But, my main concern is about the front spring.
As you already said, you guys, put the following part number "6R0411105B"
Both of your car have an 860 kg maximum permitted load on your front axle, while mine is 870 kg. 10 kg seems quite light but, still I'm a little bit concerned by the difference between the PR code.

The -15mm front suspension, with the spring "6R0411105B" has an L38 PR code while my factory spring "6R0411105C" have an L39 PR code.

I search everywhere, on ETKA: impossible to found information concerning the range of those "L39" and "L38" PR code.
Maybe it has a link between the lowering spec or not. If you have any informations, I will be grateful

[Le_Combattant]

Okey, I found something interesting:

Capture d’écran 2025-06-08 231304.jpg (108.59 KiB) Viewed 7408 times

So, If I understand, my current setup for the front suspension is G72 + L39.
It means my current load goes from 621 to 650KG.

But with the "6R0411105B" spring (-15mm), I'm not sure about how handle those numbers/table.
PR codes for this spring are: G10,G72,G73+L38

[Le_Combattant]

So today, I take some measures on my current setup:

Front:

LH:330
RH:335

Rear:

LH:335
RH:340

So, in comparison with official chart, it's very very low

But, still, I'm condused about the PR code for the "sport châssis"
G12/G70.
