Dunlop air assisted suspension kit
I'm thinking of fitting a Dunlop air assisted suspension kit to my 2015 Broadway to improve the ride and allow a measure of levelling when pitched. I'd appreciate thoughts and comments from others, especially anyone that's had one of these kits installed.
Thanks Jeff

Hi
Welcome to the forum from Bridington,modelman fitted rear air assist to his van some years ago, unfortunately he doesn't appear on the forum anymore,maybe someone else could help.
I had the Dunlop system on my Sigma and it was great.

Re: Dunlop air assisted suspension kit
I fitted the Dunlop kit to our van 5 years ago, it’s made the ride much more comfortable and is noticeably less affected when overtaken by speeding vans on a motorway, if we changed our van this would be the first upgrade I’d fit.
Our rear axle load is 2000kg and I fitted the kit when uprating to 3750kg.
I’ve found no need to fit a permanent compressor as it only takes a couple of minutes to plug a small compressor into a 12V socket 3-4 times a year.
I can adjust or equalise the pressure either side in less than a minute, even a cycle pump works ok, normally run at 32psi, easy enough to add a compressor if you often pitch on sloping ground.

Re: Dunlop air assisted suspension kit
Welcome to the forum. I go along with the other guys, they are well worth fitting. Most these kits give similar performance and I think you will be pleased with the results after fitting.
Like Spanner never felt the need to have an onboard compressor.

Re: Dunlop air assisted suspension kit
We used our rear air assist a few times on our last trip away to adjust the angle of pitch to level up .
No compressor fitted either ,just a 12 v Halfords one.

Re: Dunlop air assisted suspension kit
Thank you everyone for your very well received comments. I will proceed with the project over the winter and hopefully give you an update upon completion.
Just one other question; I realise the front suspension doesn't use leaf springs but is there a similar piece of kit to assist at the front?
Regards, Jeff

Re: Dunlop air assisted suspension kit
exactly what spanner says above. have just fitted them to our Broadway eb 2019 model and spent last month touring Norfolk. the difference is extraordinary. we also fitted different tyres as well at same time. (michelin agilis camper 225/70/r15 112Q)
we gained 250 kg on rear suspension - done because we were 60kg over the 2000 due to e bikes, bike rack and tow bar.
as an aside, makes access to spare tyre that bit easier as well.
no rolling on corners, better over potholes and speedbumps, far less rattling in the moho, easier onto the ferries, slightly higher ground clearance at rear.

Re: Dunlop air assisted suspension kit
Plymouthwelshboy, Thanks for the info. It's the better ride you describe that I'm hoping for. With the good reports from the others in mind I intend to go ahead and get the kit fitted to my van over the winter. Although the MMM article suggests that the kit can be fitted DIY I will either get A/S in Broadway or my local motorhome engineer to fit them.
Regards, Jeff

Re: Dunlop air assisted suspension kit
Out of interest, how much adjustment is there on the rear height if you increase / decrease the pressure in the bellows?
Also - how does the van feel when it is parked up? Does it feel more stable and is there less movement when parked?
Cheers

Re: Dunlop air assisted suspension kit
ah now that is a good question. i haven't played about too much with the bellows but on 2.5bar I reckon it has raised a good 4 inches or so. Certainly it is easier to get underneath to see things, to access the spare tyre, to move buckets in/away from the waste pipe tap.
parked up - it is more stable. we had to remove the rear stabilising legs when we fitted our tow bar. And ours certainly moves less when we are traipsing around her.
