Vehicle-specific step bars

Westin HDX Drop Nerf Step Bars are steel side steps designed for 2015-2022 F-150 SuperCrew and 2017-2022 F-250 and F-350 Super Duty Crew Cab trucks. The kit includes model-specific brackets, hardware and instructions for a direct bolt-on installation. They suit owners who want a permanent, rugged entry aid that matches the truck’s profile.

Sustained durability

One-piece steel construction and heavy-duty punch-plate treads resist deformation when used daily for cabin access or bed loading. The notched bar geometry adds over two inches of usable toe and heel space compared with alternative designs, reducing foot fatigue during repeated climbs. Textured black coating protects the steel from road salt and moisture through multiple seasons.

Thermals noise and power

As passive metal components they generate no heat, draw no electrical power and produce no operational noise. Surface temperature follows ambient conditions, so bars can become hot in direct sunlight or cold in winter. No wiring, fans or controllers are present, eliminating any electrical load on the vehicle system.

Questions about this item

Do the HDX Drop Nerf Step Bars create much wind noise at motorway speeds?

The solid one-piece steel bars add minimal wind noise; the textured black finish does not whistle and the notched profile sits close to the cab for quiet daily driving.

What must my truck already have for these step bars to bolt on?

Your 2015-2022 F-150 SuperCrew or 2017-2022 F-250/F-350 Super Duty Crew Cab needs the factory rocker-panel mounting points; the included vehicle-specific mount kit and hardware attach directly to them.

Will the 56-13945 bars clear the factory running-board wiring on a 2017 F-250?

Yes, the notched bar design provides over two inches of extra toe-heel clearance, so the step area avoids the OE wiring harness and any retained factory boards.
