Real OEM refers to what is typically called the thrust arm as the tension strut.

There is no part listed in the diagram for your your mystery part on my car maybe something was added: put your VIN into RealOEM.com and look at the parts diagram for the front axle.

Seems to be attached where the anti roll bar is: do you have active suspension on your truck? I know some models have a hydraulic ram on the anti sway bar to lean into curves. I've not seen how that attaches.
