Well guys the decision has been made
Thank you for all opinions, the only way to find out is ask others who have been there and done it
I opted to go Toughdog 45mm adjustables, 3" lift, 300 kg rear springs, Firestone airbags(for the extra load times), greasable shackles and all new bushes.
All booked in and happening in 3 weeks.
Now to save for F&R air lockers.
Thanks Guys,
