I would say no ... but not specifically mentioned in LVVTA thresholds .... have a read & see what you think ..section 9-1.
Might be needed if you have done other mods tho.

I would consult this link and make up your own mind.

Looks like a bit of a grey area

Modifications
16. A modification affects a component or system that directly or indirectly affects the directional control of the vehicle, and:
a) is not excluded from the requirements for LVV specialist certification (Table 9-1-1), and
b) is missing proof of LVV specialist certification

Not a grey area at all. If its not ok'd in table 9-1-1 (I don't see it there), it needs cert.
Sure it may be missed in wof inspections, however that doesn't make it legal

Using your theory you would also need a cert for installing a Thule box on the roof , as it raises the center of gravity effecting stability.
The shackles are a direct bolt on using the factory mounts so are ok in another part rules .
