More powerful rear door struts?

[Lingo_Berlo]

Doing some more serious sound isolation upgrade to my '15 Berlingo Multispace. After I did the rear door sound isolation it gained some weight and now doesn't open so easily and it slams too hard when closing.

I assume I just need more powerful gas struts to compensate a bit more door weight, anyone knows where to get those?

 I see the original struts are around 167 Newtonmeters of force if I read what's written on the strut, anyone know around 200Nm struts that fit Berlingo?

Thanks in advance!

Cheers mate,

will definitely look them up.

Wait till the weather warms up and the gas expands. They have a minimum and maximum force rating. RS components in UK sell them do you have anywhere similar.

Not sure it changes much since when I heat up the car it doesn't change much. Must wait till the summer I guess...

Here we have 6 months of cold weather so I guess I got to install stronger struts, will check the RS Components as well - thanks for the recommendation!

Bought enginr stand off these, and they do gas struts.

What have you soundproofed, and what effects has it had?

We need full details of what you've done - I would be interested in reducing road noise.  My thick rubber boot mat has helped a fair bit though - it covers the whole lot, even under the back seats.

Still working on it mate. I only did the rear door so far since it got so cold here it's hard to work on the car. I'll continue doing the other 4 doors, bulhead, floor and roof once the weather gets a bit warmer.

Rear door isolation.

And the plastic side with foam isolation - good for keeping cold or heat out of the car too.

That's why the vertically opening rear door got heavier so need new struts to balance the additional weight gain from dampening material out. Other doors are horizontally opening, thus do not need any special treatment after the isolation.

I'm doing full isolation so hopefully I'll post some details how it improves Berlingo once I'm done within two weeks or so, depending on the weather, lol.

Thnx! Will check them out too!

I think you'll find it difficult to get a good compromise of strut stiffness for your purpose. Even though stiffer ones will better support the open door they wont do much to improve the slamming because they don't have much control of the door at that point in the travel. My standard weight rear door shuts acceptably if all other doors and windows are shut but slams noisily if any are open. Thinking about it, a possible way to improve the slamming might be to add more/more progressive bump stops

Yep, I think it's true. Ideally they should be some progressive struts I reckon.

With the original door weight the stock struts worked fairly well in all situatsions though, both on supporting and acceptable slamming dampening and opens very easy. Now it doesn't open so easily - I have to use my hand to open it from quarter way all the way up. It stays up allright, but on slamming slams too hard so I aid the first step let it go after some 1/3 travel is left, then it doesn't slam so hard.

If you've got details of what you've used that would be much appreciated.

I've started to put some Berlingo soundproofing info into this thread.
