Each bar sports non-slip step pads situated perfectly in front of each door of your cab. This gives you the support you need exactly where you need it.

Iron Cross 3" nerf bars are easy to mount with simple bolt-on installation without needing to drill into the frame of your vehicle. They also come with mounting hardware specifically made to fit your vehicle's make and model.

Once they're on your truck or sports utility vehicle, Iron Cross 3" step bars look phenomenal. Choose from either black or polished stainless steel finishes. Either way, your ride is going to look the best that it ever has. Both are covered by impressive manufacturer's warranties (five year warranty on black nerf bars, and a limited lifetime warranty on polished stainless steel).

Ease of Installation
Solid, made in USA product. I was unsure if they'd be as sound as my last factory ones that had a center brace. These don't have center bracing, and don't need it. Solid bracing to the frame, front and rear, and a heavy, solid bar.

I wish that Iron Cross packaged them better, though. The first shipment had a total of 5 dents in the 2 rails. The second shipment only had 1 dent... Thumbs up to both Iron Cross and RealTruck for their customer service in making it right!
