Enhance your truck's accessibility and style with the Westin 28-534345 R5 Modular Wheel-to-Wheel Nerf Step Bars. Designed for crew cab trucks, these bars provide a safe, wide 5-inch stepping platform that spans the length of your vehicle, offering convenient access to both the cab and the truck bed cargo area.
The Westin R5 M-Series Wheel-to-Wheel Nerf Step Bars are engineered to solve the challenge of accessing high-profile truck beds and cabs. Featuring an extra-wide 5-inch footprint with three skid-resistant step pads, these bars ensure secure footing in all conditions. Constructed from high-grade, corrosion-resistant steel, the modular design allows for easier shipping without the need for expensive truck freight. The unique Isolator Bracket system provides support past the cab area, eliminating the common issue of unsupported "bouncing" or creaking found in standard aftermarket steps. Designed for a direct rocker panel mount, these bars offer a clean, professional look for your vehicle.

The Westin 28-534345 R5 Modular Step Bars are designed for specific crew cab truck models. Because vehicle body styles and mounting points vary significantly, please verify your truck's make, model, and year against our fitment database. If you are uncertain about compatibility, contact MyTruckPoint for confirmation before completing your order.
Choosing the Westin R5 series means investing in engineering that prioritizes structural integrity. Unlike generic bars that may creak or flex, the proprietary Isolator Bracket ensures a solid feel underfoot. The inclusion of a third bed-access step and the corrosion-resistant steel construction provide long-term utility, making these a superior choice for truck owners who frequently use their cargo area.
The installation process is straightforward, with an estimated time of 1.5 hours. As these bars mount to the vehicle's existing rocker panel, no drilling is generally required. We recommend professional installation if you are not comfortable working with vehicle trim or factory mounting points. Always ensure all hardware is properly tightened after the first 500 miles of use.
Q: Is drilling required for installation?
A: No, these bars are designed for a direct-fit, no-drill installation to the vehicle's rocker panel.
Q: Do these bars include a step for the truck bed?
A: Yes, the wheel-to-wheel design includes a third step specifically positioned for bed and cargo area access.
Q: What is the benefit of the Isolator Bracket?
A: The Isolator Bracket supports the section of the bar that extends past the cab, which prevents the bar from flexing and eliminates creaking sounds.
Q: Does the product come with a warranty?
A: Yes, this product is backed by a 5-year warranty.
