Considering Air Suspension on 2009 Hilux

Yes - does the OP mean airbag load assistance to the standard suspension or replace the rear leaf spring suspension and replace with a air suspension similar to what many modern landrovers have.

I suspect the former. if that is the case it needs to be researched carefully as many Jap chassis cannot handle having air bags over the axle with heavy weights as damage can occur to the chassis - in a worst case the chassis breaks in two.

The reason for this is the chassis is designed to have the weight of the rear carried by the chassis at the points that the rear springs are connected to the chassis - airbags transfer much of the load to the chassis above the axle - some models may or may not be able to handle this load in this area of the chassis.

Yeah, agree with the former too, Garry.

But the wording, to me, suggests full bottle air suspension, trailing arms, air bags, compressors, valves etc.

Plenty of reading on the subject, and no doubt enough photos, to help the OP think some h/duty rear springs are the cheaper option.

Ali, just go buy a ute that is going to do the task you require..maybe a Landcruiser.
