These kits are designed to fit single rear axle AL-KO Chassis with torsion bar suspension, but please do note, this isn't an independent suspension system, it is to assist the existing suspension.

AL-KO kits are slightly more advanced to fit than the regular chassis kits, however, your local Motorhome Service center or workshop shouldn’t encounter any problems.

We supply compressor inflation options with AL-KO kits to ensure best possible performance and longevity of the air springs to enable you to have the 5 year warranty.

PLEASE NOTE MOST MOTORHOME BUILDER ORDERS THE AL-KO CHASSIS IN THE WAY IT FITS THEM BEST.  SO MOST OF THE TIME THE CROSS CHASSIS BEAM IS NOT IN THE SAME POSITION.  THERE MAYBE ON OCCASION THE NEED TO DRILL A HOLE, MOST OF THE TIME THIS IS NOT NECESSARY.

Instruction and fitment guidelines can be found HERE

 

Benefits

Vehicle Levelling Simply by varying the air pressure in the springs, the vehicle can be
levelled both front-to-rear and side-to-side. Keeping the vehicle
level optimizes stability, ensures correct headlamp beam distribution
and reduces tyre wear arising from uneven distribution of weight.


Straight Line Stability Straight line stability is greatly increased at higher speeds, and when
subjected to buffeting from cross-winds or large overtaking vehicles.


Reduced Body Roll Body roll when cornering or negotiating roundabouts is significantly
reduced.


Fatigue Reduction and Wear Compensation Suspension fatigue is reduced, so helping to prevent leaf springs from sagging under repeated or constant loading. Any sagging already present can be compensated for. This is a particular benefit for motorhomes, which are always fully laden.


Ride Comfort Air springs help to absorb shock loads from uneven road surfaces,
therefore general ride quality is much improved.

 

Warranty All our Dunlop Air Assist kits come with a five-year extended warranty (terms apply) as well as full EU certification for legal use in EU and countries subject to equivalency

 

Up-going Chassis

 

Once the order is placed, we will get in touch to discuss which AL-KO chassis you have and which height is suitable for your vehicle. There are 3 generations of kits available, depending on the model/year your vehicle is, then under those years, there are a few variations as seen below.

If your vehicle does not meet any of the specifications below then Dunlop do not do a kit for your vehicle.  Please always call us prior to ordering a kit for an AL-KO chassis.

1. 1994-2002 (X230)

​​-Through Chassis 2cm protrusion

-Underslung Chassis 4cm protrusion

 

2. 2002-2007 (X244)

- Disc Brakes

 

3. 2007 to present (X250, X290, X295)

​-Standard Through Chassis 9cm protrusion

​-Extended Through Chassis 14cm protrusion

​-Standard Underslung Chassis 9cm protrusion

 

Is your axle Through the Chassis or Underslung?

The first image shows an axle THROUGH the chassis, the second is an image of an axle UNDERslung, as you can see, the second axle is supported by a bracket hanging below the chassis, this should be straight forward to determine as it is just a case of having a look under your motorhome.


Finding your Axle Protrusion

The protrusion is how far the Axle protrudes from the chassis to the suspension arm, it should be within a tolerance of 2cm of the measurements above. This only applies to the X250 Chassis to determine if you have a Standard or Extended Axle. The lower left image displays an 'Extended axle' and the upper right image displays a 'Standard axle'.


The last piece of information we require is your desired drive height.

As a rule of thumb, Dunlop suggests that your rear be 8cm higher than your front after kit installation. This is to give a good vehicle stance that closely resembles factory standards.


1.Put the motorhome on a flat horizontal surface.

2.Put a jack in the middle of the rear axle.

3.Now jack till the rear of the motor home is approximately 8 cm higher than the front.

4.See the red arrows here below. This difference should be approximately 8 cm for single axle shorter vehicles and 10cms for longer vehicles and those with a tag axle.

 

Once your vehicle is as above, we then need to obtain the measurement you require.

The way we decide the driving height, is determined by a measurement from the ground, up to the chassis where the axle penetrates (on through chassis) or up to the chassis at the start of the bracket (on underslung chassis).

 

Once we have this measurement, we can then choose the correct height on the kit to get to your driving height.
