Do these mount at the factory rocker points?

Yes. These mount at factory rocker panel locations — no drilling or frame modification required. Bolt directly to existing mounting points on your truck.

What hardware do I need to install these?

Mounting hardware is not specified in the product data. Check your truck's service manual or contact support with your VIN for the exact bolt specs and torque specs required at the rocker attachment points.

Will the chrome finish hold up to road salt and weather?

Chrome is corrosion-resistant by design, but regular washing in winter months keeps salt spray from building up underneath the bars. The polished finish is durable for typical truck use, but harsh climates benefit from periodic rinsing.
