Is there a problem with running them empty of air?

turns out my car has had no air in the rears pump up shocks since i bought it, so atleast 13,000k.

I put some in it, and my arse raised (what do ya know, lol)

what max psi i can/should put in them?
and whats least, as i want it sitting as low as possible.

cheers

I haven't seen a set of these in years.

You want to run the minimum possible pressure in them. I'd aim at about 5psi.

they are designed to increase the carrying capacity of a vehicle by adding air. not really an ideal thing.
we used to use them to lift the arse on cars with rooted rear suspension, for that ultra cool, prostock look it was about as cool as most VL owners, these days.

ha ha yeah, everone had them on in the 70s, stopped big wheels from scraping on guards, and looked tuff!! lol

JA5ONS

ha! tuff! lol.
i' recon i got about 5psi in them now, i'll check tonight when i put the wheels back on.
im gunna re do the rear suspention some time in the next 12 months, its like a truck to drive atm.

so if i tow the 1.6 tonne boat, should i pump them up?

cheers gents.

If I recall correctly, the minimum pressure is about 35psi and the max about 130. The only problem I see with air shocks is that if you pump them up to carry a heavier load then the excess weight is placed on the shocker mounts, not the spring where it's supposed to be. When you go around a corner, the air in the outside shock transfers to the inside shock and pumps it up. Not really good for handling unless you have separate valves. If you want to carry loads, the air bags that fit inside the springs would be better with a set of good gas shockers.

My 72 HQ has a set of these at the back, but planning on fitting some adjustable coilovers instead as I plan on running on the strip on occasion and want the car to hook up

cheers guys.
so will this explain why i have a shit ride?
if so, what is the cheapest way i can replace them with something that is a nicer ride, at about the same height (about the same as fe2 height)

it depends on your current ride height and condition of your springs.

a new set of springs and shocks.
don't go for the sports gas. in my experience, the handling improves at the expense of ride quality.
the same with heavy duty springs.
good if you want to carry half a dozen bags of cement around with you. real bags, not the pissy little things they sell these days

slip down to Pedders and have a yarn to them. using a 'slightly' heavier spring and a good set of oil shocks will do wonders.
no technical specs from me. they're just a curly bit of wire to me
