Contact my mate here in Melbourne, The Suspension Centre, ask for Rob (03) 9356 4591
tell him Max sent you.
He deals with Fox Foam Cell Struts and get somebody locally to make the coil springs for his applications. Its what I have in my hilux, they are fully rebuildable whether you want 2, 3, or a 4 inch application.
He resets the factory rear leaves, and if you want you can add a rear 1 inch spacer or an extended shackle if you want aswell.
He drives himself a previous shape GLX-R thats been raised 3 inches and runs equivalent to 33/12.5 size tyre that is actually fitted on a 27inch rim, custom import from the states, to advertise his business. dont have a pic of it, but heres a pic of my front struts-
After fitting the ARB bar, the front sagged abit so he added for me another 15mm spacer ring to the bottom shaft which raised it up another 30mm and stiffened the front end.
Heres a pic of his business partners Hilux, 5 inch front lift running 305's, yeah CV angled is maxed out but its for show not offroad.
These are old pics, when he just fitted my 3 inch as a comparison-
it'll be under 2 grand not sure how much depending on what you want, I hope that helps ya out. A couple of hilux blokes from north queensland have bought and fitted his kits after seeing them advertised on mine.
hope that helps.
