Does this mount to the factory bumper attachment points?

Yes. This is designed for factory mounting points — no drilling or frame modification. You'll bolt directly to the existing structure.

What fasteners do I need to install this?

Mounting hardware is not confirmed as included. Verify what bolts or brackets come with your assembly before installation, and refer to your vehicle's service manual for torque specs.

Does the step tread need paint or sealant before I install it?

Inspect the tread surface when it arrives. If it's bare or exposed to weather during shipping, light prep before install extends durability — but the assembly ships ready to bolt on as-is.
