Height control - what's the point?
Does anyone ever actually use the height control on their GX?
I've played with it a few times but besides that it doesn't seem to be that great of a feature. The self-leveling part of it is a great feature. But having the ability to raise or lower just the rear of the vehicle seems kind of pointless. Why didn't they make it front and rear? Rear-only height control doesn't help that much in off road situations. Perhaps its just for loading/unloading cargo...

Raise it to increase the clearance in order to drive over an obstacle (rocks, etc.)
Lower in order to clear an overhang, like branches, or getting into a garage.
Semi useful on the GX, since it's only the back (as the OP pointed out). Four corner height control is more complex and expensive (LX has it).

This system is one of the best on the market. There is an approx 4" height difference between the low and high setting. You can lower the system to load and wash the vehicle. You can raise the system for off-roading, water crossings/flooding, and going over driveways.
Where this system really shines is when towing. When towing you can lower the vehicle and back up to the trailer and when lined up simply hit the high setting and the ball moves right up into the trailer hitch. You can also use the system to adjust the approach and departure angle of a trailer and the rear of the vehicle. If backing up a steep driveway you can raise the rear of the trailer by lowering the rear. Then after the rear of the trailer passes you can raise the rear so the hitch clears. It works very well!
No matter what weight (within recommendations) you carry and/or tow the system automatically levels the vehicle to maintain ride dynamics, on the fly. You can see and feel the ride difference even when there are just passengers in the vehicle. Even when empty, the ride is better (smoother with air springs instead of steel coils). In my opinion, it is worth its weight in gold (especially if you tow).

Good info,
I was wondering why it went back to "N" when i had the setting to "L" when i left the garage. Are there any aftermarket parts to make the front adjustable off the same system as well i.e. utilise the same type airbag system inside the existing front coil springs?
I`ve seen airbags used between semi eliptical and coil springs on pick-up trucks for the same load leveling functions. Considering these GXs share the front sustension with the Prado and the IMV hilux .. there must be someone out there..

Yeah... but raising just the rear several inches doesn't really do much for overall vehicle clearance. The entire vehicle has to go over whatever obstacle is in your way... not just the back. At the front is where vehicle clearance is more important... i.e. front tires going through a rut or even more important when doing a water crossing. The only reason to have more vehicle height for a water crossing is so you don't suck up water into your engine air intake... which is at the front.

I think it would be cheaper to replace the air bags with coils, new shocks like say Iron Man or OME. I've been researching it and it's definitely cheaper, it's up to the individual if they want to keep it stock or go with the FJ Cruiser or 4Runner type suspension. Just my opinion.
