I also installed the air helpers to my Ranger. This is because of what I need to load in the canopy on certain long trips together with the weight of the caravan at the back the Ranger trops about 8cm. Not much and it does not influence the control of the Ranger at all. The airbags helps to level the Ranger / bring it back to its normal height. However, the main reason for fitting it is when driving in e.g. Botswana on twee spoor roads with thick sand with a middel mannetjie it helps to increase the height at the back with about 5 to 8 cm so that the towbar and caravan misses the middel mannetjie and also to distribute more weight to the front wheels for better traction on all 4 wheels. Works very well.
For normal driving at home I keep the pressure at 0.5 bar.
Het dit by n vriend gesien, nogal beindruk hoe dit werk met n brag.
Had them on my 1984 Land Cruiser (leaf springs front and rear) and now on my Fortuner. Best investment! Always a pleasure to see the look on the faces of petrol attendants when I pump the bags.
