I looked at Coil Rites, OEM Landrover bellows, and Poyairs. Based on convenience and cost I went with the Polyairs- $490 fitted.
With 5 PSI they give no lift, but with 25 PSI there is about a 4" lift on the unladen vehicle. With about 15 PSI there is a 2" lift and the suspension feels firmer. I have yet to load up the vehicle with the Polyairs installed, but you can see from the photo attached to this that the car was way down with the heavy trailer attached to it. Mind you, the trailer is carrying 21 jerries of fuel, two by 25 L of water, plus other gear, so there is a fair downward force on the Treg hitch.

have to drive between the oilwells Truckster 'tis a Landy and the original petrols aren't known for economy. Liked my old RR but the 3.5 was thirsty, the newer ones have bigger pots for more drinking don't they?

My car is a diesel. It was all petrol. I had to carry the fuel for two 'cruisers and a pathfinder. Two of them didn't want to run Avgas in new cars, and the other wanted to dilute the Avgas with ULP.

Bob, I hope you charged them the appropriate pump price at fill ups. Not many convoys take a fuel tanker with them. Good on you Bob........

Baz, of course you must be arse heavy and that is why the Polyairs don't lift you. Do all Exploders expect Flop Bot?

They struggle to lift the back of the Nissan with so much there too......... For a while there was a small cut in the tube to the left bag which let the passenger side hang low. Thought it was my light weight the drivers side being up. LOL It would drop the pressure over a few days by about 10psi.

Bob, I guess it depends on what size PolyAirs are fitted to what springs. My PolyAirs only give about a 2" at 26 psi unladden. That then becomes a zero lift when ladden and with the trailer hooked up - just as it was intended.

Does yours now revert to the std ride height when you load her up, or does the rear still sit higher, given you start with a 4" lift?

Rohan,
I haven't loaded it up yet with the Polyairs fitted but I expect with a full load it will drop down to a 2" lift with 25 PSI. I am using the units designed to be used in vehicles with a 2" lift.

These ones designed for a 2" lift you mention, have they just a 2" spacer block which gets fitted at the top between the bag and the top spring mount. That's all my GQ was fitted with. Looks like the bags are just the standard height ones. Is this what they do with all of them? Certainly no complaints about them, but just curious.

John,
I don't know. Just looking at them without the other size for comparison its a bit hard to tell.

Polyairs do not give you the lift, they assist the suspension with the weight factor in the rear end. Only way to get larger lift is to replace the suspension. Polyair will stipulate they do not lift the vehicle.The product saves suspension wear.

Call it what you will, when I inflate the polyairs the vehicle goes up. In the unladen vehicle the rear is 4" higher with the polyairs installed and inflated. I suspect this is because I have installed the polyairs designed for the vehicle that alreadty has the 2" lift. Regardless of what polyair stipulates, the vehicle does get a substantial lift. I can send photos if you like.
