Will this bar clear my trailer hitch?

The reinforcement bar mounts at the factory bumper attachment points. If your hitch is already installed, test-fit the bar before final tightening to confirm clearance.

Do I need to remove the rear bumper to install this?

Installation method depends on your Odyssey's current setup. You may be able to bolt it on from underneath, but full bumper removal could be necessary depending on hitch or other accessories already installed.

What fasteners do I need?

This bar uses the existing factory mounting holes. Bring your hardware specs to a Honda dealer or consult your service manual for the correct bolt size and torque specifications for your model year.
