Do these require drilling or cutting into the frame?

No. These mount at factory anchor points — no frame modification needed. Bolt directly to existing locations designed for this application.

What hardware do I need to install these?

Fasteners and mounting brackets are not included with this kit. You'll need to source OEM or equivalent hardware that matches your vehicle's factory mount specifications. Refer to your vehicle service manual for bolt size and torque specs.

Can I keep the black finish as-is, or do I need to refinish it?

The bars ship with a factory black powder coat ready to install. If you want a different color or finish, surface prep and paint will be necessary — mask off the stepping surface before applying any coating.
