I will also do some towing from time to time, twin axle box trailer that can legally weigh up to 2 tonne.



I'm starting to think airbags may be an option but don't have any experience with them.



Anyone got any thoughts?


When I was looking to sort out my saggy rear, I was told to get springs over airbags. Apparently airbags can cause chassis rails to crack from point loading. Iím sure it doesnít apply to all vehicles, but Iím getting 500kg constant load springs installed.

Air assisted suspension should be mandatory on this class of vehicle to keep the rake of the vehicle constant.

Your next problem is damping, 300 odd kg weight on one axlechange probably more with overhang means the damping will be a compromise, that's where unassisted leaf springs have an advantage on coils.

From years of trial and error and doing what your suggesting but at gcm max+ , i ended up with on the old ute and replicated it on the new ute , the highest constant load springs , old man emu springs and shocks as well as airbags ,so I'm not expecting the bags to do the grunt of the work just support and level the load , with variations in loads etc its the only way to go , also when loading or unloading the ute pod i can pump the bags up slide the jackoff legs in , drop the air and drive out . I also carry a tool box on one side of my ute and its the only way to level up . D Max's have a strengthening right where the bags go . I've done over 200k with this setup and pushed it to the max , loads , roads , 4x4 etc .

On a leaf rear end they load the chassis at a point that they arenít designed to be loaded. Many dual cabs suffer cracked chassis as a result. Much better option is upgraded springs however you will suffer a bit of harshness unloaded.

I upgraded my springs to 250kg constant load after weighing and calculating the average payload. It rides fine when unladen (accessories add 250kg to kerb weight) and just did 10,000km (over 3000km on dirt) loaded to gvm and towing 1400kg and it rode beautifully.

Thats why you do a suspension upgrade first , airbags to level up only . D Maxs have a strengthening most likely for the coil setup for the Mux . How do you level from left to right with springs only ? You cant , out of the 50psi available you might only need 20 or 30 . also bags take the roll out of the vehicle from side to side in the twisties , I'm throwing the bags in the new rocket this weekend .

Distribute the load.

How ? Box has to live on the rght allowing for 1200 sheets or materials on the left , variable loads daily . So nearly 200kg on one side and anywhere from 0 to 200kg+ on the other .
