Default This "correct 19mm spring" cobblers..

After a spate of phone calls from confused customers concerned about the springs they are about to buy being "The correct 19mm" thickness I thought I would take a few sets from the shelf and measure a few up, and post the results here for you to see.
I'm not exactly sure of the source of this 19mm cobblers, hopefully this should put pay to it.
What confused me is the fact that most of these springs are tapered wire, meaning the wire that the spring is made from tapers from about 10mm up to around 19mm in the middle, then back down to 10 ish again.
I would hate to drive a T4 with springs that were 19mm throughout their length!

Gen VW (888 special springs, white spots)

no Pics, soz like, sure you know tho...

Coils 7.666
Ends - 9.9mm
Thickest part - 19.8mm
Overall height - 255mm

Gen VW (Caravelle - 1996, 2xbrown spots - heavy duty!! may have had wrong springs fitted!!)

No pics.

Coils - 6.75
Ends - 10mm
Thickest part - 17.9mm
Overall height - 270mm


H&R (advertised as -20mm to -40mm, depending on spec of van to start with)



Coils - 7.5
Ends - 10.2mm
Thickest part - 19.7mm
Overall height - 242mm
TUV Cert - Here


KW (advertised as -40mm)



Coils 7.25
Ends - 9.1mm
Thickest part - 19.4mm
Overall height - 245mm
TUV Cert - Here


Weitec (advertised as -40mm, the lighter duty parallel wire one, the cheaper one)



Coils 7.75
Ends - 13.6mm
Thickest part - 13.6mm
Overall height - 250mm
TUV Cert - Here


Weitec (the proper ones, the tapered wire ones, the ones that will carry weight)



Coils 8
Ends - 10.96mm
Thickest part - 18.5mm
Overall height - 235mm
TUV Cert - Here

So, there you go.
The 19mm ain't far off to be fair, but I think it's a bit daft to go saying only anything thats 19mm is "correct" when as you can see from the small range above they vary quite a bit between the brands, the Weitec HD one weirdly having fatter ends and a slimmer middle, but it's not just down to how it's wound and the thickness of the wire it's also down to how the spring is tempered.

In all fairness I really don't think you can go far wrong with most of these springs, go for the cheaper Weitec ones if you really don't expect to carry weight, but the difference in price between the other is minimal and they are all TUV approved (hence modest drop)
I will say the one I measured that didn't match the TUV cert (That I noticed anyway) was the KW, so, I presume subject to change applies here, or engineering tolerances..

Also worth noting is that I have measured the spring including is surface protection, obviously once this has been stripped away the spring will be much narrower.

Mods - I have used pictures on purpose without watermarks with my business name on, not that that stops any of the other traders nicking images from my site and posting them on theirs!! Bless.

For those wishing to buy springs, I hope that this thread is of some use to you, I just wish I had some Eibach to measure up as I think it would be useful to add this info to this page.

Simon.

Oh, and anyone ever seen a TUV cert for any Jamex springs?
I don't think I ever did when I sold them, they certainly weren't in the box!

That one is the light weight one

List prices can be found here for KW http://www.kwsuspensions.de/uk/index.php

and here for Weitech http://www.weitec-suspensions.co.uk/uk/index_uk.htm


Very comprhensive list, nice input


the 19mm reference is in comparison to stock springs which is near enough for most applications.

Thats the lighter duty one, not the HD duty one, read the headings



Prices, Out of the tapered wire ones the H&R are the cheapest, but to be fair theres not much in it.
I like H&R due to their heritage, plus the T3 stuff is sh!t hot.
KW and Weitec are fine, not driven Eibach, can't comment but I hear nothing but positive comments about them.

Very good interesting post Simon!! I thought I had settled on the Weitec HD kit for my Westy but after seeing the pic of those H&R's I'm liking the look of them

Simon, you have the H&R's on your van don't you? any idea which would sit lower out of the two? I don't want it really low just want to lose a little gap out of the arches.

Much of a muchness I would say, I am more than happy with mine.
not dissing the rest, why would I, I sell them all but I think that the H&R's prices just that bit cheaper, better value for money.
The only ones I would have reservations about selling to you would be the cheaper Weitec's.
And like i SAID SOMEWHERE ELSE, CAN'T REMEMBER THE THREAD, Ah, b*llocks, I hate caps lock me...
Anyway, There should be another brand on the market soon, bit cheaper still but has been modeled and tweaked from the above information but made from parallel wire, just as a budget line as I understand that a lot of people simply don't have the money to buy these springs above, I appreciate they ain't cheap so I'm working on a work around so you get the features but at a better price, and something that will carry the weight that the ones above will.

Thanks Simon, the H&R's do look better value for money as you say and also look like they would handle the heavy westy better. I have to count my pennies are they in stock?

Turn around is usually 7-10 working days, just sold the sets I had at the garage, more on it's way, if you want 'em they come from Germany, same as KW and Weitecs.
