Will my factory parking sensor fit through the pre-drilled hole?

Yes. The sensor hole is sized and positioned for factory Toyota sensors. Test-fit your sensor before final installation to confirm alignment.

Do I need to remove my factory bumper, or can this bolt directly to the frame?

You'll remove the factory bumper first. This bumper uses the same mounting points—no frame drilling or reinforcement required.

Will a trailer hitch still clear this bumper?

Mounting method and hitch clearance depend on your specific hitch model and frame setup. Measure the depth of your hitch receiver and test-fit before committing to installation.
