Hotchkis TVS for Suburban?

[65imp]

As I plan to lower my Sub sometime in the next year I have come across all the glowing reports about how well the Hotchkis TVS system improves overall handling while achieving the static drop I am looking for.

As it is designed for the trucks, it SHOULD bolt up to a Suburban, but I imagine the extra weight over the rear axle would be a little less than ideal for the spring rates and possibly the thickness of the rear sway-bar.

Has anyone been down this road? Any input?

I know the kit is quite costly and I may just go with an ECE setup or possibly CPP, but I want to flesh out the potential of using the Hotchkis stuff before making my final decision.
