Rough Country 51143 is an SRL2 adjustable aluminum step rail set for the 2021-2026 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.

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.
