Air Suspension

We can fit the Dunlop Air suspension to most vehicles giving several benefits to the overall ride of the vehicle from a full auto system with on board compressor to adjust the Air bags themselves with gauges which are easy to inflate with something as simple a bicycle pump.

The semi air suspension systems will greatly increase straight-line stability on motorways, strong cross winds and when being overtaken by heavy vehicles. They enable you to, stiffen the rear suspension by increasing the air pressure alleviating any sagging of the rear suspension due to incorrect or over loading, and allowing the vehicles ride height to be kept level. Body roll on roundabouts and when cornering is also decreased and the general ride is much improved.

Most people fit air assisted suspension units to restore the rear ride height of their motorhome. Unlike normal vans, motorhomes are always fully laden, especially if additional rear racks are fitted to carry bikes etc. so the rear springs do sag after a while. These units will restore the ride height, however everyone who has had air assisted suspension systems fitted to their vehicles all say they are also impressed with the added benefits of improved ride, improved cornering and being less prone to side winds and buffering by large HGV’s

Prices are available on contacting us, as kits are specific to vehicles and depend on if you want a compressor or not, all kits are only fitted in the workshop.

We can now get the Dunlop kits for the Alko Chassis

Coil Spring Upgrade

Front-suspension upgrades involve replacing the coil spring with a heavier-duty item. This is most popular on Fiat/Peugeot/Citroën-based motorhomes, especially A-class ’vans with a heavy bed over the front seats. Many smaller Hymers were built on the light Ducato chassis in the early 2000s, and often sit very low at the front. Fitting heavier-duty coil springs will usually give a ride-height increase of between 25-50mm at the wheelarch, but it will almost always provide improved ride comfort. Bear in mind that on vans more than five years old, the McPherson strut and top mount should be replaced as well. The strut is the suspension damper (usually wrongly referred to as the shock absorber), a hydraulic unit that controls the suspension movement, and one that can wear out. This obviously adds cost to the job, but because it all needs to be removed to fit the springs, it makes sense to replace them, too. The top mounts are also known to fail, so again it’s a good idea to replace them while it’s all apart.
