My personal opinion is that there are multiple variables the prevent upgrading the suspension from being just "plug and play".
1) Vehicle "ride" is subjective. What one person calls "sporty" another might consider "overly harsh" or "punishing".
2) The weight range of the 100 series. The "perfect" shock for the 5500 pound stock vehicle might feel "dangerous" on a fully loaded and armored vehicle. The perfect shock for the fully armored and loaded 7000+ pound behemoth might feel like it's filled with concrete on a stock vehicle.
3) Jumping into "lifting" the torsion bar front-end before fully understanding it. The torsion bar front suspension is both a blessing and a curse. It makes it real easy to lift the front end by just turning a few screws, but there are a few caveats. Whether it is "to make room for larger tires" (which you really don't get from just cranking the torsion bars), or to try to get rid of the "stinkbug stance", there tends to be a tendency to "over crank" the front torsion bars for lift. The preload on the torsion bars really only adjusts where the front suspension is "at rest" and it doesn't add any travel to the front suspension. Any "lift" you get from cranking the torsion bars reduces the down travel available in the front suspension. You can recover a little down travel from aftermarket UCAs and longer shocks, but it's not a huge amount. Some also appear to get confused over adding "upgraded" torsion bars. The aftermarket torsion bars tend to have a stiffer spring rate, which is useful for carrying additional weight, but really don't add any lift per se.
