Do these bolt directly to the truck, or do I need drilling?

They mount at factory rocker points — no drilling or frame modifications needed. You'll bolt them straight to existing attachment locations.

What's required before installation?

Surface prep depends on your truck's condition. If mounting surfaces are clean and dry, you're ready to bolt them on. Clean any debris or rust from contact points first.

Will this finish hold up, or does it need sealed?

Polished silver holds up well outdoors, but regular washing keeps it looking sharp. Sealed or bare — your choice — but either way, this is designed for open-air durability.
