Will these bolt directly to my truck without drilling or welding?

Yes—these mount at factory rocker points with no modifications needed. Standard hand tools and basic mechanical skill are all you need for installation.

Does the silver finish need prep or touch-up paint before install?

The bars arrive pre-finished and ready to bolt on. If you plan to paint them to match a different color, light scuffing and primer will prepare the surface for your paint.

Can these handle weight, or are they just for stepping up?

They're designed as entry steps. Use them for cab access; don't rely on them as grab bars or load-bearing points while the truck is in motion.
