The lengths that are quoted by the manufacturer are only approximate. If the actual length turns out to be within 3mm of what the manufacturer claims, you are doing well. Also, springs might vary a little from batch to batch or from different factories even if they are supposed to be exactly the same.

 

I once looked at some OEM springs in a Mercedes parts department. They both had the same OEM part number so should have been identical, but they weren't. Standing them up together on the bench, you could see that they were about 10mm different in length.

 

When you purchase a pair of springs, always weight them on some accurate digital kitchen scales. A matched pair, that came out of the same batch at the factory, should weigh within a few grams of each other. Also, stand them up together and they should appear to be identical in length. Also, check the wire diameter with digital calipers, check the outside diameter, and check the number of coil turns. Make notes of all your findings, and take some photographs.

 

If after fitting your springs you find that your car is too high or too low, or the ride is too hard or too soft, you can go back to your notes and photographs for further investigation.

Когда вы покупаете пару пружин, всегда взвешивайте их на точных цифровых кухонных весах. Подобранная пара, выпущенная из одной партии на заводе, должна весить в пределах нескольких граммов друг от друга. Кроме того, поставьте их вместе, и они должны казаться одинаковыми по длине. Кроме того, проверьте диаметр проволоки с помощью цифровых штангенциркулей, проверьте внешний диаметр и количество витков катушки. Запишите все свои находки и сделайте несколько фотографий.

Hello, dear Carlston! The springs 5Q0411105DQ I ordered have arrived. The inspection carried out found that the parameters of the springs correspond to the declared ones, except for the weight. Spring weight 2.160 and 2.190 kg instead of 2.3. What to do? Is it permissible deviations between the springs and both springs from the set value?

5Q0411105HS are listed at around 2.03kg to 2.05kg.

 

The only difference between 5Q0411105HS and 5Q0411105DQ appears to be the wire diameter.

 

13.00mm for the 5Q0411105HS and either 13.25mm or 13.50mm for the 5Q0411105DQ.

 

If you have 13.25mm wire diameter, I would expect the weight to be around 2.11kg to 2.13kg.

 

If you have 13.50mm wire diameter, I would expect the weight to be around 2.19kg to 2.21kg.

 

Two matched springs of 2.16kg and 2.19kg in weight isn't that close, as 2.19kg is about 1.4% heavier than 2.16kg. However, as long as the other specifications are similar such as wire diameter, number of coil turns, and uncompressed length, then you shouldn't have a problem.

 

What brand of springs did you order?

The springs were ordered from an official Skoda dealer, a manufacturer of VAG. Given the variation in weight, is it worth installing them?

The fact of the matter is that the diameter of the wire is 13.5, and one of the springs weighs 2.16 kg.

As they both have a wire diameter of 13.5mm, I doubt you would notice any difference when fitted.

Hello dear Carlston! I installed the front springs, now this is the situation: the front is higher than the back.

The first photo is of the rear arch. What to do?

 

May be, https://www.autodoc.co.uk/eibach/13828886 because it is still 4 mm longer.

Hello dear Carlston! I installed the front springs, now this is the situation: the front is higher than the back.

 

Did you fit new 1K0511115CT rear springs?

 

Is that about 8mm higher in the front?

 

The reason of course, is because you have fitted Kodiaq 5Q0411105DQ front springs with a wire diameter of 13.5mm instead of the standard Scout 5Q0411105HS front springs which have a wire diameter of 13.00mm.

 

I suggest you change the Kodiaq 5Q0411105DQ front springs to standard Scout 5Q0411105HS front springs, which should lower your front end by about 6mm assuming that the uncompressed lengths of both springs are about the same.

 

An alternative could be using helper springs that some people use when they tow a caravan. This would make the rear springs stiffer and increase the rear ride height.

 

Although Eibach R10494 are listed at 387mm in length, you may find that they are the same length as your current springs. This is because the uncompressed length of aftermarket springs will often vary by a few millimetres from what the manufacturer claims. Also, the springs might come out of the factory with slightly varying lengths.

 

Can you return Eibach R10494 rear springs for a full refund, if they turn out to be less than 387mm? If they really are about 5mm longer than your current rear springs, then they would help level up the car.

 

Also, consider "Grayson spring helpers" as shown in the photo below.

 

These spring helpers lock out one of the coil turns, so as your rear springs have about 8.8 coil turns these might increase the spring's stiffness by about 10% and increase your rear ride height by about 6mm.

Instead of 1K0511115CT rear springs, you might want to take a look at 1T0511115AB and 1TO511115AC as shown in the chart below.

 

As you can see, 1K0511115CT is listed as weight range 0YH, 1T0511115AB is listed as a weight range 0YJ, and 1T0511115AC is listed as a weight range 0YK.

 

These lists of springs that are ordered by weight range aren't always logical. So it could be that 1T0511115AB and 1T0511115AC are heavier duty than 1K0511115CT, but they might not be.

 

Can you find out the specification of 1T0511115AB and 1T0511115AC, such as wire diameter, number of coil turns, uncompressed length, weight, etc.? It's possible that they won't be available to order even through a Skoda dealer.

 

1T0511115AB and 1T0511115AC isn't available aftermarket, and hence I can find no specifications for them.

You could try the Eibach R10494 rear springs matching OEM part number 1K0511115CT.

https://www.autodoc.co.uk/car-parts/oem/1k0511115ct?search=OEN 1K0511115CT

 

If your current springs have started to sag with age and use, then new rear springs will raise the rear ride height.

 

Also use new top and bottom seats for the rear springs because the original ones might have started to compress.

 

New rear shock absorbers might also help the rear ride height, because these are gas filled and provide some uplift...at least when new.

 

If you do change the rear springs, compare the uncompressed length of the old and new springs.

You have a 2018 Octavia MK3 2.0TDI 135kW/184PS Scout 4x4.

 

What springs were fitted when the car left the factory and what springs do you currently have?

 

The car might have left the factory with 5Q0411105HS front springs and 5Q0511115AM or 5Q0511115AN rear springs. Because the car is a Scout, these are increased ride height springs.

Какие пружины были установлены при выходе автомобиля с завода и какие пружины стоят у вас сейчас?

Currently 5Q0411105DQ. But I'm interested in the following, without reference to the car model.

5Q0411105DQ (height 326 mm, thickness 13.5 mm), 5Q0411105DR (height 323 mm, thickness 13.9-13.7 mm, characteristics are established by actual measurement, manufacturer data could not be found). At the same time, the analogue for both springs is SUPLEX 39686 https://www.autodoc.de/suplex/20493476 (height 326 mm, thickness 13.8 mm).

Now the questions:

which of the springs (5Q0411105DQ or 5Q0411105DR) will give more ground clearance?

will SUPLEX 39686 be better than both springs, or are analogues made from such materials that, despite the stated dimensions, they ultimately correspond to the performance of the original?

If the original front springs have a wire diameter of 13mm and they are changed to front springs with a wire diameter of 13.75mm, they will be about 15% stiffer than standard...all other things being equal such as the number of coil turns.

 

I suggest you try going for softer but longer springs than these, so that the unladen ride height is about the same but without making the front suspension too hard.

 

Bear in mind, that different brands will often have slightly different ideas of what the specification is of a particular OEM part number. For example, Suplex list their Suplex 39686 as having a wire diameter of 13.75mm even though Suplex sell this spring to replace the same OEM part number (ie. 5Q0411105DR) as the Eibach R22922.

 

Looking at the figures, I suspect the Eibach R22922 would increase the front unladen ride height of the Octavia MK3 2.0TDI Scout by about 10mm. If you change the tyres from the standard 225/50R17 to 215/55R17 (perhaps with a change of rim specification, eg. to 6.5Jx17 ET38 from the standard 7Jx17 ET45) you would get an additional 5.75mm of lift. So with the change of front springs and the change of tyres, the front unladen ride height should increase by about 15mm compared to the standard Scout.

Long time since no update with my Scout chassis parts, but I ended up replacing all shocks and front springs in October 2023 after a clutch failure (was driven approx 270 000km at the time). Rear springs I had already replaced in 2022.

 

Eventually I went for this setup, my car was 2.0tdi 150hp + manual Scout 2016:

 

Front shocks BILSTEIN B4 OE Replacement 22-230522

Front springs SACHS 993 960

Rear shocks BILSTEIN B4 OE Replacement 19-230559

Rear springs  SACHS 992 103

 

At the same time I replaced the lower control arms to front, ball joints and front stabilizer bar rods. After a 4-wheel alignment the car was really nice to drive, the suspension was stiffer then earlier, but not harsh. Should have done the updates earlier. I swapped my scout last october to a 2018 Audi A4 Allroad with 150,000km on the odometer, and I think that the Scout was at least as good to drive as this is now.

 

So, best springs to fit to the rear to match Eibach R15459 springs, ride height and general driving but as stiff as is reasonable to assist towing/loaded driving please? SACHS 992 103? Or the EIbach or Bilstein? Thanks.

Here are five rear springs that I would consider when looking for a spring that matches OEM part number 1K0511115CT. This includes the Bilstein 36-199570 that you linked to.

 

As previously mentioned, 1K0511115CT and 5Q0511115AN are the same spring. The proof for this is Kilen 65073 and Lesjofors 4295087 which are sold to replace both 1K0511115CS and 5Q0511115AM...as shown in the link below. The benefit of choosing 1K0511115CT over 5Q0511115AN is availability and price. Kilen/Lesjofors suggests their 1K0511115CS/5Q0511115AM rear spring for the Octavia MK3 4x4 Scout...and 1K0511115CT or 5Q0511115AN is one up in the hierarchy which is about 5% stiffer.

Edited 28 February, 20251 yr by Carlston

I would go with the spring equal to either 1K0511115CT or 5Q0511115AN. I think this will give the best load capacity, and match the front.

 

I don't have a straight dimension or sidepicture from my car, but here is one picture with the above mentioned setup together with 225/55R17 wheels which eliminated the speedo error and gave approx 11mm more ground clearance. 

 

Edit. Here is also a comparison picture of the oem rear shock vs. the bilstein I installed. In the oem shock there is a plastic part which basically limits the piston rod movement. It will not fit to the bilstein shock, in theory one could install ca. 25mm thick nylon washer etc. to imitate the functionality. I didn't put anything to the shock and never had any issues bottoming out etc during my 40,000km with the new parts.
