Do these mount to factory points or do I need to drill?

They bolt to existing frame attachment points—no drilling required. Just locate the factory holes and fasten down with a socket set.

What fasteners do I need to install these?

Mounting hardware is not included with the bars themselves. You'll need to source bolts, washers, and lock washers that fit your frame's factory holes—grab what matches your existing hardware diameter and pitch.

Can I use these bars as actual steps, or are they just for looks?

They're designed to function as entry steps—the 3" diameter tube is solid enough for occasional boarding. They also protect your rocker panels from damage, so they earn their place either way.
