    Hi guys and gals
    I have a 2015 Swift BoleroFB with a dinette which has a current weight restriction of 3700kg
    I am having an issue with my rear suspension. To carry the scooter we have I need to upgrade from 3700 to around 4000.
    I have been told this can be achieved by fitting air suspension in place of the rubber stops. My problem is that I have no rubber stops :Eeek:

    My rear suspension looks like this:

    Can anybody advise what I need to do?

    TIA
    John.

    You have an alko torsion bar axle which does not have rubber stops. Those are fitted on fiat leaf springs. Search for alko air suspension and get wallet ready.

    As above ... definitely an Al-Ko chassis which we have on our Augusta and have AS-Air suspension fitted, which although not cheap is a great system.

    In case you are not aware, some Al-Ko axles have a couple of grease nipples which require regular attention ...............

    Copied from the Al-Ko web site:

    Should I grease my AL-KO axles?


    Yes. We recommend greasing your AL-KO axles every 20,000 Km, or once a year whichever comes sooner.


    Ideally jack the motorhome so both wheels are off the ground. The grease nipples are situated on the axle tube.


    5-7 pumps of a hand grease gun for each side should be sufficient, until resistance is felt. Excess greasing could break the seals and fill the torsion tube.


    We recommend 3 greases: Shell Retinax LX, Co. Kluber GL 1501 and Co. CONDA 3746 SP.


    Failure to grease regularly could result in a requirement to replace the axles.

    You should be able to make out one nipple in this image covered with a yellow plastic cap ... only a couple of inches inside the chassis member.

    Thanks for your input everybody,
    It looks like I need to get underneath and see if I have an 'up going chassis' :Eeek:
    Don't know what I can do if it can't be upgraded :(

    I'd not heard of the problem with "up-going chassis" ... you may find it is only certain kits that have the problem.
    If you are going to Peterborough it would be worth talking to Phil on the as-airsuspension stand and I'm sure he will look at your m/h and give you the necessary info.
    I have used them on two motorhomes and can highly recommend them for quality, service and all round great people.

    Yes defo make sure you grease the rear suspension :)

    That's a great picture @icantremember posted. Mines similar, only it has a shield covering the water tanks. You'll see the yellow covers over the grease nipples, just need to pop them off and add grease (easily said) :)

    Do you happen to know what the difference between your 2400 and my 2000 suspension is Andy?

    Yes It must be the light or standard chassis then. Have you spoken to SVtech? They will tell you what is possible if anything at all.
    Mine is the heavy Alko and 2100 front 2400 rear
