Question: |
What's the difference between FULL
air suspension and SEMI air suspension? |
|
Answer: |
The difference between a FULL air
suspension set-up and a SEMI air suspension is vast. A Full
air suspension is where the original metal springs are removed
from the vehicle and replaced with a lot of new parts, plus
air springs. A SEMI air suspension kit is fitted in addition
to the original vehicle suspension, and therefore assists the
original suspension. |
|
Question: |
What's an air spring? |
|
Answer: |
An air spring is the rubber
bellows (doughnuts) that are inflated to provide the lift and
cushioning effect to your vehicles suspension. |
|
Question: |
Can I fit a semi air suspension
kit to my AL-KO chassis? |
|
Answer: |
There are no kits available for
your chassis, we have even been in touch with AL-KO who have
confirmed there is nothing available for retro fitting. |
|
Question: |
How much air pressure should be in the air springs? |
|
Answer: |
Air Pressure requirements vary from application to personal preference.
However a good starting point is around 40psi for
motorhomes, or at the very least enough pressure to get your
vehicle level. |
|
Question: |
Is there anything I should be
aware of when jacking up the vehicle? |
|
Answer: |
Its very important not to allow
anyone to raise the vehicle body without releasing the
pressure from the air springs. Its okay to raise the vehicle
by placing the jack under the axle.
By raising the vehicle body
without supporting the axle with pressure in the air springs,
will stretch the springs beyond their design specification,
thus potentially causing un-repairable damage if done with
pressure in the air springs. |
|
Question: |
Do the air springs improve the ride? |
|
Answer: |
When the vehicle is loaded, the air springs help the existing suspension carry the load and improve the ride a great deal. |
|
Question: |
What is the minimum air pressure? |
|
Answer: |
If you are not going to use your
vehicle for several weeks, its recommend the pressures are
dropped down to the minimum 5psi. |
|
Question: |
Do the air helper springs replace the existing suspension? |
|
Answer: |
No. As the air springs are
attached to the existing suspension. |
|
Question: |
Do the air springs increase the
legal payload capacity of my vehicle? |
|
Answer: |
No. But the air springs will maximize
the vehicles existing carrying capacity within the vehicles GVW.
They will not enable you to legally carry more than what is
stated on the vehicles data plate.
Do not overload the vehicle. |
|
Question: |
Will the air helper springs stabilize my vehicle? |
|
Answer: |
Yes, the more air pressure you add the less vehicle movement you get in return. |
|
Question: |
What's included in the basic kit? |
|
Answer: |
Nuts, bolts, brackets, air springs, air line and manual inflation valves.
Everything is included for a manual inflation system.
If
you want 'in cab' pressure gauge and valves, they are
available as an optional extra with the Firestone kits, but
they are include with the Airide kits |
|
Question: |
Can I have different air pressures in each air spring? |
|
Answer: |
The ability to compensate for off-centre loads is one of the best features of the air spring.
Yes you can have different pressures in each air spring. |
|
Question |
How do I know if I have ABS
brakes? |
|
Answer |
Basically non ABS vehicles have
attachments/levers down to the rear axle. These lead up to a
valve block which is connected to the rear brake pipe
system. An
example can be seen here |
|
Question: |
Where should I mount the inflation valves? |
Answer:
|
The inflation valves should be mounted in an easily accessible location.
Firestone recommend placing the inflation valves on or around the rear
bumper, but with motorhomes, the location will be different,
we've seen then mounted in the step area of the rear access
door. However if you have the optional extra gauge and valves,
you can mount them inside the drivers door so you can visually
check the pressure every time you get in. |
