Outer Limits 4x4 Board

Gday boys and girls, Im currently building a 92 4x4 spacecab. I want it to be a bit of an all rounder, but this is the first rodeo I have played with. I have built hiluxes and sierras, cruisers and patrols, but this is the first IFS truck I have played with.
I want it to be a bit of a tourer, so only a 2inch lift, with a set of 31s. Ill be making the interior as I go, so basically Im after which brands I should be looking at for parts in the suspension category, from there, anybody who has built one up, any help would be muchly appreciated!

Ok different question, has anyone noticed any detrimental issues with flipping the ball joints and shaving the bump stops down?

So whilst shopping around for new torsion bars today, after calling a few suspension mobs, and visiting a few reputable suspension/4x4 supplies stores, Ive been told that all torsion bars are in effect the same. As long as they are 40mm lift indexed, all of them will act/react the same. So I have the choice of tough dog, old man emu, rock crawler, efs and everybody else, am I just better off to find the cheapest 40mm lift? or is there a difference?
