The Calmini kit is sweet, but does NOT give more articulation. OME is the only one that has a strut with longer travel,

That not correct. The stock strut location leaves 2" of unused travel which the Calmini spacers ultilise. In addition the A-arms move through a different arc to the stock arms which also gives a little more travel. The OME kit gives 1.5" of extra travel on the front, the Calmini lift gives around 2.5" of extra travel. - thats around 50% more travel than stock. At the rear the Calmini kit has longer springs and longer travel shocks.
I have the Calmini lift with the OME struts but I had to reduce the height of the strut spacer to prevent the CVs binding, I run camber correction bolts to correct for the 'double correction' of the OME struts and the Calmini arms.

When I emailed Calimini's 'engineers', they told me none of their lifts for Trackers / Sidekicks gave additional articulation in the front. The spring travel is the spring travel. The only way to get more spring travel is to install a longer spring (and corresponding strut that can take advantage of that additional travel). Placing a spacer on top doesn't allow the spring to stretch / compress any more - it just puts a puck there, and "lowers" the spring thus "lifting" the truck. They also said their strut isn't designed to have longer stroke, it's only designed with a longer shaft so a strut spacer isn't needed.
