I'll begin with mine.

'86 pickup, Rancho angled upper a-arms, OME 23.4mm torsion bars, low profile upper arm bump stops, 1.25" ball joint spacers, machined upper ball joints, custom shock mounts, 8" travel shocks, machined and modified Downey slip yoke axles, Rancho center steering link, "555" japan made larger pitman and tie rod ends, idler arm gusset, and longer brake lines.
12" of wheel travel, stop to stop. Adjusted to a conservative 3" of lift. Currently running 31x12.50 xterrains, have run 33x12.50 and plan to run 35x12.50 tires.
The only down fall about this setup is the same with any other torsion bar setup. Depending on how much lift I adjust the torsion bars for, I lose some ease of upward wheel compression. Set at 4.5" of lift I had very poor compression yet it woud still fully compress when the front was loaded. I have found that set at 3" of lift with aprox. 1" more compression over drop, has yielded the best compromise between wheel travel on the trail and handeling on the street.
I like this setup becuase it now has 12" of wheel travel, handles much better on the street, and keeps the stock track width. In keeping the stock track width however, I'm leary of the outter birfield joints and tie rod ends. So far with moderate to hard 'wheeling over the course of one year neither have shown any problems. The whole cost of this has been lost track of. The Rancho and Downey parts are discontinued but at new ran around $800. I'd estimate that I have about $400 in it so far, which includes the price I paided for the parts used.
