Yep, never heard of airbags busting a Landcruiser chassis so don't worry about that one. On the dual cabs, people load too much weight behind the rear axle and the chassis flexes too much between the cab and tray. Patrol chassis bend because the chassis is a bit weak - especially the coil towers on the coil cabs.
I've had airbags in my 79series for a few years now:
- don't use them as a substitute for strong springs - weight still needs to be supported on the spring eyes as the manufacturer intended. Use them to fine tune the rear height.
- Be prepared to lose about 80mm of rear articulation, so you'll start lifting wheels
- Don't put any more than say 25 psi - if you put more in, they will become
rock hard and that's when chassis damage will happen. The airbag mobs sometimes tell you 100psi is OK!
- They reduce the sway considerably on a 79series because the 79's don't have a rear swaybar. Probably will reduce sway on a 76series but less so.
- Your 76 series has shorter rear leaf springs than the 78/79 series, so is more likely to get a hard ride from stiff springs.
