Do these bolt to factory holes on my Sienna, or will I need to drill?

These mount at factory rocker points — no drilling required. Fastening method and any hardware should be confirmed during fitment, as rocker panel configurations can vary slightly by model year.

Can I install these myself with basic hand tools?

Mounting at factory points is straightforward DIY work. You'll need standard sockets and wrenches to secure the boards. Refer to your vehicle's service manual or contact support for torque specs and any additional mounting hardware requirements.

Will the aluminum need to be sealed or protected after install?

Aluminum resists corrosion on its own, but if you want added protection or a custom finish, you can prime and paint before installation. Install first, then seal — this prevents moisture from trapping under the boards.
