Ghost, TiAg:

If you could get right under the hitch attachment bolts (at the rear pan) then the OE hitch is rated for a 600 lb vertical load. This hitch would be similar in capacity, as it is loading the rear attachment point in shear, with no bending moment.

But bring the trolley jack back towards the middle of that aftermarket hitch strut, and you introduce bending forces. Also, the rear of the X5 weighs a bit more than 600 lbs. Quite a bit, in fact.

Not that I'd recommend it, but you could just as easily lift on any part of the sheetmetal underneath the vehicle, it would have the same strength.

I'd say it is a terrible jacking point, for those reasons.
