The Rock Slide Engineering BD-SS-300-BR4 is a two-in-one system for the 2021-2025 Ford Bronco 4-Door: a fully functional, trail-rated rock slider with an integrated powered step. When a door opens, the step deploys a full 12 inches down from the body of the slider; when the door closes, it retracts and sits flush against the slider. A built-in sleep mode limits battery drain when the vehicle sits.

The sliders are built from 10-gauge steel with stainless steel and aluminum internals to resist rust, finished in textured black powder coat. Because the slider body doubles as rocker protection, it takes real trail abuse while the motorized step makes daily entry easy for every passenger.

What's included: This is the complete set shipped in 2 boxes — both the driver-side and passenger-side sliders — plus a stand-alone plug-and-play wiring harness, magnetic door sensors and mounting hardware. The individual BD-SS-300-BR4D (driver) and BD-SS-300-BR4P (passenger) sub-parts are the single-side halves of this same set.

Fitment: Fits 2021-2025 Ford Bronco 4-Door models only. Does not fit the 2-Door Bronco or the Bronco Sport. Installs to factory mounting points with no drilling, no splicing and no rewiring.

FAQ

Is the step powered?

Yes. The step is motorized — it automatically drops 12 inches down when a door opens and retracts flush when the door closes, with a sleep mode to protect the battery.

Does BD-SS-300-BR4 include both sides?

Yes. BD-SS-300-BR4 is the complete 2-box set with both driver and passenger sliders. The -BR4D and -BR4P part numbers are the individual single-side halves.

Will it fit a 2-Door Bronco?

No. This set is for the 4-Door Bronco only.

Does installation require drilling or wire splicing?

No. It mounts to factory points and uses a stand-alone plug-and-play harness — no drilling, splicing or rewiring, so it preserves the factory warranty.
