    Wheel-to-wheel nerf bars

    Westin ProTraxx Step Bars are precisely what you need if you are tired of the struggle when getting in and out of your vehicle. They have all the right features to make climbing into your truck the easiest task, starting with the indestructible stainless steel construction, the extra-wide steps, and the antislip pads. All of these blend to offer sure footing and solid support.

    Constructed from stainless steel

    Constructed from stainless steel

    The stainless steel construction is virtually indestructible and will not get damaged by merely getting hit by the road elements. It is also strong enough to handle daily foot traffic and this allows the step bars to serve you for the longest time.

    5 inch diameter tubing

    5 inch diameter tubing

    The 5-inch diameter tubing is among the widest in the market and they offer enough room for any shoe type and this means sure footing.

    30-degree bends with seamless domed ends

    30-degree bends with seamless domed ends

    The 30-degree bends on both ends of Westin ProTraxx Step Bars are unique and are sure to add style to the whole look. They also have seamless domed ends that keep water and dirt off the insides of the step bars to prevent corrosion and rusting.

    Available in stainless steel and black powder coat

    Available in stainless steel and black powder coat

    Westin gives you the option to match the step bars with your factory finish to create an OE appearance by providing the step bars in both black powder coat and stainless steel finish.

    Include a third step pad

    Include a third step pad

    The step bars also facilitate easy access of the cargo in your truck bed, thanks to the third step pad that is located on the furthest end of the bar. This is a huge plus and you will hardly find it in most step bars.

    Deep paved waterways

    Deep paved waterways

    Westin ProTraxx Step Bars have deep paved waterways that channel out water from the pads and help keep them dry for additional safety.

    Non-slip pads

    Non-slip pads

    Though their main purpose is to create enough traction for sure footing and prevent slipping, the treads on the step pads together with the Westin logo, also add to the style and create a rugged look

    Bolt-on installation

    Bolt-on installation

    Installing the step bars requires no drilling on most applications, and with the well-detailed installation manual, you will have them up and functional in just a few minutes.

    Lifetime warranty and 3-year warranty

    Lifetime warranty and 3-year warranty

    Westin backs the polished stainless steel bars with a limited lifetime warranty and the powder-coated black step bars with a 3-year warranty.
