BillTex,
I am skeptical. It looks too much like a kicker-shock or anti-wheel-hop rig we've put on 4X4's for decades. Those weren't worth much as they were in the way of anything else you had besides a few leaf springs. I think you should buy and install the RAS and give it a good workout then report back on your findings, for the good of your buddies on the Forum.
Currie has an anti-sway rig which is a sway torque rod with wings for rock crawlers called 'Antirock' that keeps really great stability when way off camber and I am a believer in that one. I don't think they have a truck app yet, but who knows? Here's a link: paste in browser,

I know the Currie's but have no connection with them, business-wise.
regards, as always, jefe
