    Aftermarket polyairs, then rear springs lift?

    The airbag people haven't responded my enquiries, so I will ask the gurus here.
    I have fitted polyair airbags to my standard D2a rear suspension, but am now thinking of fitting a pair of available Lovells longer (about 40 mm?) rear springs.
    Question 1 - can I retain my existing airbags - and just fit a spacer or whatever?
    Question 2 - while I'm at it, can I still use my yet to be installed standard Bilstein shock absorbers with the longer springs.
    PS. I'll be in touring, not weekend warrior mode useage, so comfort/carrying loads rather than articulation is the objective.

    There are spacers available to suit, The Airbag Man should have some, or Heasmans should have them too, ARB, Opposite lock.

    The Polyairs will be ok with a spacer, In fact as far as I know that is all they do if you order polys for a raised susp.Spacers are generally poly blocks . As for the shocks, My first thoughts is no, cannot be used with longer coils. however it would pay to lay them alongside a shock to suit a 2" lift, they may just be long enough Otherwise all you will do is wreck them as the longer travell coils try to work there magic. As in broken mounts,cracked eyes, etc.

    a word of warning!! I HAD red poly-airs fitted to std springs and they worked very well, but when I fitted a set of 30mm raised coils I had problems. The bags were ok for length after a spacer was installed but the new coils, which are Tough Dogs which are the same as King Coils with the new type of steel in them, the coil wire is more open by about 30mm. This allowed the bag to expand OUT between the coil wire and they ultimately failed/split. I didn't bother to replace them, just removed. Heasmans here in Sydney advised that a Sleeve for the bags should have been used and this "should" have stop the bag from expanding the wrong way. They said "should" but would not guarantee that it would fix this, so I just removed mine.
    If your raised coils have similar coil spacing to the standard then with a spacer you will be fine.

    You need spacers for the airbags as stated before.

    No, standard shocks can't be used with 30mm lift.

    I have standard LR shocks in my vehicle with lifted rear springs. I'm not sure how much the lift is as I got them secondhand but the disco they came off was sitting fairly high, Mine has a ply drawer unit with lots of tools/bits in there, big battery and a steel roofrack which would pull it down a little. In saying this I will be changing the shocks down the track.

    I think it unlikely that you would have a problem with a 30mm lift with standard length shocks.
    I had a 50mm lift with standard shocks and no problems.
    Only when I went to off road mode, i.e. another 40mm lift, did I start to top out the rear shockers occasionally. So I installed +2's in the rear.
    Give the Bilsteins a go.
    By the way, my front shockers are still standard length and have never topped out.
