Do these bolt directly to my truck, or will I need to modify anything?

These mount at factory rocker points — no drilling, welding, or frame modification needed. Fastening hardware compatibility depends on your truck's specific attachment method; verify with your vehicle's service manual before purchase.

Can water and mud get trapped inside the honeycomb?

The honeycomb design is open-faced, so water and debris drain through instead of pooling. You won't have standing water issues like you would with a solid step bar.

Should I paint these before installation, or do they come ready to mount?

Paint or protective finish is not pre-applied. Plan to prime and paint or apply a protective coating before install to prevent rust and match your truck's finish.
