Outer Limits 4x4 Board

ive got an 89 model 60 series. it has 3 inch ironman suspension (springs not shackles) which was on ther when i bought it and doesnt flex as well as i would like her to. my brothers stock suspension out travels mine by far.
just wondering what everyone reckons would be the best suspension option to go for should i take the whole lot out and start again if so what suspension option would be best and i live in QLD so cant go soa.
any pics would be good help to. cheers

start with checking your shock lengths then start pulling leaves out one at a time

what hillbilly said,alot of off the shelf kits are pretty stiff,also u could have the heavy rated springs,for heavy loads,though not sure they have a heavy and normal load setup,also have u got swaybars,newer 60s usually have front and rear sway bars,if fitted that will prevent articulation
