GU 4" lift

You will need to the xtra work with a 4 ins lift, it is not big dollars just time

The difference in the cost per spring would be about $25.
If this lift is a kit you would need to know what is in each kit to make some sort of judgement.
personally I would get my springs made for me by a spring maker and buy what ever ealse I needed from the relative suppliers.
I could give you a list but not tonite I have to go to work

ok this is what you need ,

4" springs , I recoment Kings or Dobsons

extra long travel shocks , you can run ranchos with pin to eye convertors but I dont recoment them for such a heavy car. I recomend you use a pedder / munro / tuff dog or Koni , if you do use the munro or pedders , wou can only buy a 2 inch longer travel shock , so you need to make some 2" EXTENTIONS ,

You will need longer brake lines , 4" longer actually lol . Dont forget the travel you will have when a wheel drops in a rut .

You will need longer diff breathers , You should run them to the top of your engine bay with fuel filters .

You will need a castor correction system . I recoment castor correction plates , but you can get away with correction bushes

You will need to buy adjustible pan ards , since your wheel track wioth move 1" to one side

You will need spacers for the front sway bar , so it wont hit yout front tail shaft when fully extended . Or you may want to just remove it .

If you dont want to do all of the above , dont it at all .

Hope this helps

Have a read in the GU Modifications section on the Patrol Owners Forum, heaps of big lift discussion: Patrol4WD.org forum

Gday mate,

If money is not option, would go the 4 inch lift. But to be honest, my truck runs better on the 3 inch (dobinson 3 inch extra heavy duty) than on the 4 inch, tracks much better and is a great ride. Saved around $1,500 for 1 inch.

Picked up my dobinson kit including dampner for $700 neat.

Cheers

Chris.
