My Iron-man 4" Lift kit(Coils, shocks, adjustable panhard rods, extended brke lines, castor plates, sway bar links, all rear trailing arms, and abrake proportioning valve bracket) Cost me 2500$ total, because at the 4wd show, one of the guys at the stall accidentally gave me the wrong price.
I used the quote he gave me as proof, and only got charged 2500. I have since installed extended bump-stops, a extra heavy duty roadsafe draglink and tough dog XHD steering damper so that takes it up to about 3200.

I am very happy with my suspension. It has heaps of flex and is more comfortable to ride in than standard. A funny thing is the rear right swaybar link had a bolt come out, and when you plant it in second on a hard corner, the front left wheel comes a good 200mm of the ground!
But because of this I get more flex, so I still havent got it fitted.

The only gripe I have is te rer trailing rms. they are iroman ones and they are SHIT. Never buy them people.

Cheers
