Do these rails bolt directly to my bed, or do I need to drill holes?

These mount at factory rocker points — no drilling required. Use your truck's existing bed-box fastening locations.

Will I need additional hardware or fasteners to install these?

The assembly does not include mounting bolts or fasteners. Check your vehicle's service manual for the correct fastener size and torque spec for your bed attachment points.

Can these be repaired if chrome starts to peel?

Chrome plating is not easily repaired at home. If plating damage occurs, local chrome shops can strip and replating — factor that into long-term ownership. Avoid road salt and rinse regularly to extend the finish.
