Re: Too short to close hatch!
I would recommend putting a strap. Lowering the suspension is far more expensive than installing a strap.
And besides, all one would have to do is remove a bit of the interior panels on the tailgate, install your strap (double-sided tape or whatever method you prefer) and reinstall panels.
