hi all
has anybody had any experience with polyair springs they are being proposed by tjm as part of a suspension upgrade of our l c 100
seems we can have the best of both worlds with stiff suspension when towing & softer around town by adjusting the air pressure ( which can be done with a bicycle pump)
they claim to be tough stones etc

We have installed the Firestone bags which sit inside the existing coils on our LC 100 TD - see the airbagman.com.au for more details

Very happy with the additional rear lift and the reduced "rock" which these provide. It is true that you can adjust the pressure depending on conditions, but even on high pressure (eg 30 psi) the ride is not harsh, only firmer, so I don't tend to reduce them down for city dirving at all.

Would definitely recommend, (If you are baed in Sydney, can provide advice on installer),

Coincidentally we had these fitted today on our LC100V8. They are matched with 22mm springs, the idea being that the combination gives good strength with the van on without a bone shattering ride with it off. Stephen and Debroarh will let you know tomorrow when i try it out!

Highly recommended - alter the pressure to suit the load - as quick as checking a tyre pressure.

I had Firestone airbags fitted and can recommend. I generally run around town with 10 psi and about 20 psi when towing a 18ft BT. Works a treat

Another thought............ the remote fill/deflate valve which is the same as a tyre valve sits just behind the rear wheel mud flaps on the LC 100. Dead easy to check pressures or adjust.

thank you all
the fitters were suggesting they normally put the valves beside the filler cap sounds neat & tidy & out of the way access???

We fitted heavy duty springs all round and PolyAir bags at the rear to our LC100 about three months after we took delivery of our 20' BT. The difference in handling was almost unbelievable. No more wobble; the BT just tracks cleanly behind the Cruiser. Have done around 30,000 kms since with no drama.

We got them installed in our Landcruiser 100, then travelled 3800km back to Adelaide. The whole lot handle a treat, but there are some thing to be weary of. When you detach the van, back the pressure off otherwise you may get a fair bit of body roll. Prior to hooking up, re-inflate to 20psi or you wont get the jockey wheel up (may even struggle then). I have a 12V compressor and am making a socket to power it up from the live feed on the car trailer socket. The user information I was given was WRONG. Never inflate the bags over 20psi or they will damage. Mine are getting replaced (free of charge) and I belive other customers are getting contacted. I have opted to replace the entire rear spring package with firestone airbags. Have heard nothing but praise for them - am getting a credit on the intial spring bags, so only costing an extra $1300 (manual inflation type).
