Anyone using ironman constant loads in the rear

I currently have the performance springs in the rear 0 to 300kg but find it sags a fair bit when loaded and the camper on 150kg ball weight i am just wondering if anyone has the constant load springs and if they are noticiably stiffer or to stiff

Have you considered fitting polyairs or Firestone bags in your existing springs?

Yes I have Ironman constant load 2inch lift springs in the rear with the firestone airbags as I tow a caravan regularly and they perform extremely well, and I haven't experienced any sag when unloaded.
I've had them installed for 2 years, with alot of outback Australia travel with a Goldstream crown, including Gibb River Road, Gary Junction road etc... and the springs have handled very well
