City,
Let me try to explain the geometry, if I can:
When the trunk is closed, the strut is pointing down from the attachment point on the body (high point), to the attachment point on the trunk lid (low point), thus impossible to lift.
When the trunk is raised about 3-4 inches by hand, the strut is LEVEL, still impossible to lift.
When the trunk is raised to about have way as shown in my earlier post pictures, the strut will push the lid up and hold it up.
Now remember, I have the Mopar Spoiler on my trunk, which is quite heavy. How far the trunk would need to be raised before it would push up without the spoiler, I don't know, but from the geometry, it would definitely be greater than the 3-4 inches, which is the Level point, as mentioned above; my guess is 6 - 10 inches, for the mechanical advantage of the strut to over take the weight.
Now, if you were to install a basically straight push strut from the floor of the trunk, to basically push straight up, and compress completely when the trunk is closed, then maybe.
Also, there is no spring on the trunk lid hinges to help lift or hold it up.
I hope this helps.
Later,
