Do these bolt straight to the frame without drilling?

Yes. They mount at factory hard points on the frame — no holes to cut or weld. Use the hardware provided and tighten everything down with basic hand tools.

Will the black finish chip or fade if I'm rough on these?

Powder coat is tough, but steel bars take abuse over time. If you see chips or rust spots, sand them smooth and touch up with black spray paint designed for metal. Salt and mud will accelerate wear, so rinse regularly if you're in harsh conditions.

Can I install these on a lifted truck?

Frame mounting stays the same regardless of suspension height. Step height relative to the ground will change with a lift kit, so measure before you order if ground clearance is a concern for your application.
