Do these bolt directly to the factory frame, or do I need to drill holes?

They mount at factory rocker points — no drilling needed. Bolt straight on using existing attachment locations on your Outlander Sport.

What fasteners do I need to install these?

Mounting hardware is not included with these boards. You'll need standard bolts and fasteners appropriate for your vehicle's rocker panel attachment system — check your factory service manual or test-fit before purchasing fasteners separately.

Will aluminum running boards rust or need any special maintenance?

Aluminum resists corrosion naturally, so they're low-maintenance compared to steel. Occasional wash-off of road salt and debris will keep them looking sharp long-term.
