|Dunlop Air-Assist Suspension - Semi-Air - 5yr Warranty||
Quote of the moment: "no hesitation in using your company again & recommending to friends." PW
Semi-Air Suspension by Dunlop: One of the very best ways to fix a saggy bottomed motorhome! How do we know? I've driven a few and the one with air springs was the best of the lot. Also now that the once cheap extra coil springs are so much more expensive airbags are the really obvious choice.
The sag disappears but so does the wallow and a lot of the roll, resulting in an altogether better drive with better stability on motorways and an overall better ride quality too. The assistance is easily user adjustable via simple air pressure changes, even with side to side differences to compensate for some uneven loading - so typical of layouts with offset fridges, water tanks, etc.
As a result of course suspension fatigue is pretty much halted as the air bellows take much of the strain.
Ideal to improve - motorhome - motorcaravan - camper - campervan - 'dormobile' - however named!
Huge Range of 'Van' Applications: to suit the usual - and some unusual - motorhome base vehicles. Although I know the product well* this is a new range for us so we're starting with just a few vehicles and will build up the range over time. If you have a specific vehicle interest we'd be pleased to try to help - * Apart from motorcaravanning I once worked as a techie in a Firestone factory making airbags.
A-Class / Alko Chassis? Sorry no. Problems with Alko usually lie in the suspension itself and adding airbags will not solve it, may even make it worse. This is a professional, specialist supply & fit task not DIY. This often applies to A-class motorhomes so you will need to find out quite a bit about your A-class spec.
Why Dunlop and not say Air-Ride? We've nothing against Air-Ride™ or indeed Drive Rite™, and they've made a great job of bringing the technology to our rather ordinary van chassis rather than specialist trucks, trains, ambulances, buses, etc. Full or Semi-air suspension is even used on high end cars from Rolls Royce, Mercedes and Range-Rover but do note we're only talking Semi-Air here. i.e. air assisted suspension mostly sitting between the rear 'cart' springs and chassis where maximum stability can be achieved, often replacing 'bump stops' which also act as high load spring assisters on some vehicle chassis (some Ducato included).
So why Dunlop? Well just look at the Dunlop product features • Full 8" 200mm dia airbags/bellows - and size really matters in bellows giving better ride and more progressive suspension at quite modest air pressure, long life too • Anodised rather than painted metal components • Captive nut air connections for long life and reliability • Long warranty • Great instructions and support. • Quality product, development and customer service from a quality European company at very reasonable prices. • 5 year warranty. So what's not to like? as my offspring say!
Fitting or Kits? We don't offer fitting but do offer a range of kits for DIY fit or for workshops / mobile engineers to fit for you. The Rear Semi-air Suspension Kits are the most popular. The price of the kits ranges from the basic version with two simple air inlet valves that you use to inflate the airbags to the desired pressure right up to deluxe versions with built-in heavy duty 12v compressors & gauges for push button operation from the cab. All offer the same height and ride improvement, it is just the inflation convenience that changes, the simplest and cheapest being just like topping up your tyres one at a time using the standard supplied twin Schrader Valves. The basic kit includes the fittings pictured right - airlines, twin valves and ties, The optional on-board Gauge Kit is pictured left - this "Gauge & Twin Valve Kit" is supplied with extra length airlines to reach the cab and this allows inflation, with readout, together or separately, and is normally mounted inboard in a cab footwell so available in LH, RH, and Vertical versions. Nominally LH & RH are for LHD and RHD - on the assumption it will be fitted in the drivers side footwell. The RHD version is pictured in the kit left while the LHD version is pictured lower right alongside the Vertical version. Although not essential this gauge kit does add both convenience and consistency at a reasonable price so recommended. The Compressor Kit needed to create a deluxe installation is far from cheap so this does add quite a bit to the overall price but you do get lots of convenience, reassuring reliability and easy changes in pressure to change level or rear ride height whenever you want. The deluxe features are usually ordered as upgrades to basic kits. If planning later upgrades remember to route the airlines to a suitable location at the outset or be prepared to invest in more airline when upgrading! If you have a good idea about the real detail of your future plans it may be a good idea to tell us about them before ordering so we can help to keep redundancy minimal. It is all fairly straightforward for kit only or kit + gauge & valves.
Your Vehicle: We/you will need to know a bit about your vehicle to
get the right kit.
main thing is the chassis. Importantly, is the chassis standard Fiat,
Peugeot, Mercedes, whatever or one of the the special AlKo rear chassis for motorhomes?
Is it the standard 3.5t or a higher rating like the 'Maxi chassis'? Then
what iis the model year? - this is based on chassis build dates and not registration
dates which can lag far behind when motorhomes are involved! Model year changes can usually be identified visually - so if in
doubt about yours checkout these great Wikipedia links, each offers a wealth
of information and invaluable vehicle pictures for model/series
Also if a brake-height sensor (Load Sensing Valve or LSV) is fitted you may need to get under the vehicle to identify and/or possibly photograph the LSV type. This is then compared with the Dunlop info/instructions to get the right sensor version in the Dunlop kit. A typical schematic for 94-02 Ducato is shown above left and we offer LSV pictures of the two X230 types below. Apart from differences in the kits, the LSV is often adjusted on installation to maintain rear brake efficiency at the increased ride height when fully loaded. ABS brakes can also be an issue especially where a model range came both with and without ABS brakes. In some kits there are additional components supplied, in others none are needed, in some an adjustment is required, each is chosen to be correct for its particular vehicle type and specification.
If in doubt please don't guess but consult the Dunlop literature and if still unsure.
Originally marketed as AJV, these are far superior kits but apparently similar to others on the market!
Which LSV Type? - check under your 'van to see which you have and compare to any photos below!
Alko Torsion Suspension Kits? Sorry no. The problem with Alko is usually in the suspension itself and adding airbags will not solve it - may even make it worse. This is a professional, specialist task. This often applies to A-class motorhomes so you will need to find out quite a bit about your A-class spec.

Ducato-Boxer-Relay-Jumper X250 ABS 2006-14 Build fitted with Fiat-Peugeot Rear Leaf Springs
The X250 chasss was released in late 2006 but many converted vehicles like motorhomes weren't sold until 2007 so there are 2007-reg vehicles on both older and newer chassis - use the picture right to identify the later type. The same mixed build & registration dates apply to the 2014 change, that latest model is pictured just below. The Basic Semi-Ait Kit includes: Airbag assemblies x2, Airline tubing x2, Galvanised mounting hardware for square section axle 75x75, Twin Schrader manual inflation point. The X250 model is fitted with ABS brakes. Order >>
Ducato-Boxer-Relay-Jumper X290 ABS 2014-Date Build with Fiat-Peugeot Rear Leaf Springs
The X290 / Euro-6 chassis is fundamentally similar to the X250 and takes the same kit. There are however minor differences in brackets and cables at the rear and these require small tweaks as part of the fitting procedure - download an instructions upgrade/supplement PDF by clicking here. The picture right shows a Fiat X290 van but the cab is the same for most motorhomes apart from the slight differences between the Fiat, Citroen & Peugeot styling around the radiator grill. As with the X250 the same basic kit includes: Airbag assemblies x2, Airline tubing x2, Galvanised mounting hardware for square section axle 75x75, Twin Schrader manual inflation point. This model is also fitted with ABS brakes. Order >>
