You can find side rails on some Lexus models right from the factory. They're better known as step rails. Less often, you might hear them referred to as running boards, especially on SUVs. The sports car crowd calls their variants nerf bars, a term taken from "nerfing," meaning rubbing against or bumping into another racer. Many names aside, a good set of original step rails provides a better stepping surface for getting into and out of your Lexus than a bare door sill. If you've got the real deal, you probably already know that they mount just inches from one. Install yours lower than that, and entry and exit get even easier. This is especially helpful if your Lexus SUV is lifted. Running boards are different. They mount flush with or at least closer to your vehicle's rocker panels. That offers better ground clearance than everyday OEM step rails off the shelf. They're also generally wider and flatter profile-wise, and their treads are board-length. In short: if you're looking for a set of the solidest, most dependable steps for your Lexus, running boards are it. Either way, we've got the best step rails for a replacement project or an upgrade: genuine Lexus. Save time by buying them online today, right at our auto parts counter.
