Make it easy to get in or out of your truck with Ionic Pro Series 4" oval stainless nerf bars. 4" step bars are perfectly sized to give you a wide and safe step area and they add a subtle style. Not too garish and not too small either.

Ionic Pro Series oval tube steps are made from durable materials that are built to last through even the roughest conditions that you put your truck through. The 4" oval style is also a great match for today's larger trucks that sit a little higher and having a step makes getting in or out easier and safer for you and your passengers. Their wider, non-slip step pads help provide improved traction under any weather conditions.

Ionic knows you want accessories that make your truck look good. They've designed their 4" oval nerf bars to make your truck look absolutely amazing. You can choose the visually appealing mirror polished stainless steel.

Installation is easy with the included custom mounting brackets and hardware. Most side steps can even be installed without drilling. If you plan on putting them on yourself, you should give yourself about an hour and half (that way you have time to admire your handiwork).

Each set of Ionic Pro Series 4" oval nerf bars is backed by a limited lifetime warranty for your peace of mind. Whether you're mudding, working, or just running to get some groceries, you can count on these nerfs to stay put and deliver results every time you take your pickup for a spin. Get a pair coming for your truck now!
