Gas strut drop down bed confusion (1 Viewer)

[CazPaul]

I sent a photo and VIN to Concorde dealer Southdowns and they have come back with the gas strut I require.

The original strut is rated at 1000N but when speaking to other people with drop downs(not Concordes), Hymers they say they use either 1700N or 2300N.

The bed is a big, heavy lump.

So question is would you go with what Concorde say?

They take 2 to 3 weeks to come from Germany or is better to just go to SGS engineering but what Newton rating should I go for. I have put a message on the Concorde owners group but got no reply.

I bought some from SGS, made the mistake of ordering what they had listed as Hymer bed struts, the ones they sent were much lower rating than we actually had fitted

Now reordered from them same size but much higher number, can’t recall the values now

I would be worried about the bed lifting if too strong a strut was fitted though ours is really heavy must get round to fitting the new ones

Thanks David

The price from Concorde is £265.32 for 2 struts, I presume a lot more expensive than the SGS ones.

About £60 from memory

I will have the 1700N fitted but not used you can have even cheaper to try just need to get Terry over to swap them

What length are they David fully extended?

If you can duplicate the size with adjustable ones from SGS then they would work, get over strength ones and let the gas out a bit at a time until they work okay.

Thanks Mike, I didn't know you could get ones like that, I thought the pressure newtons were fixed

What length are they David fully extended?

I think they get measured hole to hole centre

Mine are 390mm and rated at 2400N

This is one of the dead ones already removed, we now have new to refit and 2 x 1700N to take back off

Thanks David, I will measure ours, im still confused/amazed by the rating difference, yours are 2400N ours are 1000N, our bed is heavy like everything else in the van.

Can that length be adjusted a bit if its not quite the right size? Its 390mm with one of the end fittings on? and not the other end?

That figure is centre to centre of holes, one end is very fixed, the threaded end could be undone a thread I guess to lengthen it a little

Difference probably due to the counter lever mechanism, I suspect the Hymer & Concorde use different designs.

Yes good thinking Lenny, so 1000N for mine then probably correct?

Is the 1000N rating from your current ones or is that what Southdowns say? If it's just what Southdowns say, have a good look at your struts the rating will be on there somewhere.

So these are whats on the end of my struts

Current ones originally fitted on my van 1000N, Southdowns say the same as well. Just a few people with Hymers have said they wont be string enough as they are using in excess of 2000N but I take your point the arm mechanism will be a different design.

The adjustable ones come with a small Allen key so you can let the gas out a little at a time. You have to be careful as once it’s out it’s out.

SGS will regard them if you want and can even overgas a bit if required.
