There's a lot going on here...

1) reworked spindle... restores UCA working angle and R&P working angle
2) Lower control arm drop bracket
3) shock mount relocated with coil over springs

Road testing.... I don't know if this is the same vehicle but the suspension set-up is similar.

Looks great and love the innovation. Would love to see us employ a measurement standard for this (and other) mods. Something other than the subjective 'if felt awesome'. Maybe its as simple as a matrix showing the various components on one axis and RTIs on another. That would go a long way to clarifying cost/benefit analysis of the various options out there. The luster of a uber fancy mod should also be framed in the context of both the measured change and price. Ride quality, obviously, would remain a subjective layer.

Here is where it gets expensive. Custom CVs to match up.

Well MT has there own machine shop I presume the can one off the axles pretty easily. To reiterate this is a one off project / POC.

My understanding was that if you crank the torsion bar to far, it does limit down travel, maybe I have that wrong.

Abstractly travel has nothing to do with TBars... its the range of motion of the components (Shocks, Control Arms etc).

When you add the TBars into the equation you are now working against spring forces to move the suspension in the range of travel. If you "crank" the TBars you are pushing the suspension down (lifting the truck) farther in it's available travel - in theory cranking the t-bar would push more down travel. Since you have spring force to contend with you have more resistance to up-travel.

Add the shocks into the mix and you now have an up and down travel limiter.

So I am sure this has been discussed but could not find a thread.

With the ability to do so many major mods, like SAS, engine swaps etc.. How hard would it be to fab up a smiliar set up to the 200 series Coil over front suspension to replace the torsion bars in the 100?
What would you gain in travel?

Nothing. Without reworking all the arms, steering location and links, cv positions etc, the torsion bars is not the limiting factor. Going to a coil over just give you the advantage of more spring choices vs the relatively small number of choices for torsion bar spring rates.
