About this kit

SRL2 Adjustable Aluminum Step Rails, fitment-checked

Rough Country 51143 is an SRL2 adjustable aluminum step rail set for the 2021-2025 Ford Bronco 4WD. It fits four-door models only — two-door Broncos are not covered. The kit pairs a 67.5 in powder-coated aluminum rail with powder-coated steel mounting brackets and zinc-plated black stainless hardware, and the step pads slide along the rail so you can set placement where you actually use it.

These SRL2 adjustable aluminum step rails for the 2021-2025 Ford Bronco 4WD cover the Base, Big Bend, Black Diamond, Outer Banks, Badlands, Wildtrak, Everglades, Raptor, First Edition, Heritage Edition, Heritage Limited Edition, and Stroppe Edition submodels shown in the fitment section — four-door body styles only. The box holds the SRL2 step assembly, a 67.5 in adjustable rail, and the bracket hardware, and the modular layout lets you add or reposition steps later. Rough Country lists a 1-2 hours install time, and a downloadable installation guide is available before you start. Shipping weight: 53.0 lb.
