Do these come with all the bolts I need to install them?

The assembly includes the bars themselves and mounts at factory rocker points. Confirm bolt compatibility with your JK's factory attachment hardware before installation — you may need fasteners from your local hardware store depending on what's already in place.

Can I paint over the black powder coat or does it need prep?

The powder-coated finish is sealed and durable as-is. If you want a different color, light scuffing with 220-grit sandpaper followed by primer and paint will work, but the black finish doesn't require any prep out of the box.

Will these fit my two-door Wrangler?

These are designed for four-door models only — the length and mounting points are specific to the extended wheelbase. Two-door JKs require a different product.
