Rear Axle overhang / air suspension ?…

[Just us on Tour]

Hi All
Some of the circa 9m tag axles MH have a large overhang .Is the chance of grounding out common ? And if so will semi air suspension overcome this problem ? I spoke to a chap at the NEC on the VB stand . I asked him what extra clearance I could expect to achieve if semi air was fitted . Sadly he didn’t know and was going to get my local dealer to contact me …..mmmm….I am still waiting . Also , anyone had it done ? Was it worth it and may I ask approx cost .
Also any recommendations for a good supplier/ installer .
Thank you .

We have GS on our double axle, this in itself already raises the back end quite a bit just in normal ride mode. Then of course you can increase either end as required although for ferry boarding they always suggest to reverse on if you’re likely to ground. This year we did a Norway trip and took in some fairly adventurous routes with many sharp inclines, no issues what so ever and never had to play around with the suspension.

Our carthago e64 had air on the rear when we got it cannot believe the difference in ride quality the ability to lower it if plot too far out for the levellers and to lift it on tight slopes although we did not need to lift it on a 5000 mile trip to Norway. It was fitted by SAP at Doncaster.

Can't comment on the extra height difference but we had VB semi air fitted to rear of our Burstner in 2022. Rosmia in Sussex fitted it for £1500, that included the compressor so you could adjust from the cab without visiting a garage to find an air hose. Would recommend.

I fitted air assist to the rear of my 7.2m van which raised the rear by 100mm at 2.5-3 bar.

We have VB rear air fitted on a 6.6 m van with a 1.5m overhang (from the rear of the wheel...not the centre) At 2bar it raises the rear c 3cm, nearer 4cm at 2.75-3 bar. Not as much as I had been led to believe if I'm honest.

Is that on an alko axle or standard spring van chassis?

Fitted Dunlop air assist to rear of our Peugeot Boxer and it gives greater stability and comfort. Found the best bit last week ! Got a puncture and could lift the rear end significantly enabling me to get to the mid ships spare wheel carrier quite easily. Hope not to use this benefit too often

Not 100% up on the fords but dont expect they are much diff to fiats, our old fiat chassis would but the rear a good 15cm higher than standard. Is yours restricted due to anything anti roll bar, shocks or even spring travel

I’ve had air suspension fitted on mine and have 2dials in the cab and a switch to pump up the rear of van by 20-80mm for going on ferry etc, also stops the movement when a lorry overtakes you, will look up the make, cost was about £1000

Thank you for the info that’s exactly what I need and wanted to know . Are you on a fiat or Merc and are you on tag or single axle ? The make and whomfitted it for you would also be very useful . Thank you

What about front suspension would it help ? my Peugeot boxer Bailey advance tends to be lower at the front and grounds out when reversing down a slight incline.

I don’t have air on the back of my Elegance tag axle. Surprisingly I’ve not scraped it once getting on and off ferries up in Scotland. I did scrape the edge of the towbar / bumper once turning round on a big grass bank. Mine has a 2 metre overhang so you can park on some shorter pitches.

Had AS semi air fitted oh rear of our Dethleffs tagger, lifted about 100mm at rear end if required. AS Air suspension Uk Ltd, situated near Warrington Cheshire.

I think you have to take account for the length of your over hang at the rear as the longer it is the higher it will go we had an Exsis I which have a fairly short overhang and the air assist on an AL-KO chassis would only give an extra 30-40 mm

Glide-Rite on a Carthago tag axle 104mm at rear, 55mm at wheel arch unladen. Would be more fully laden
