Rocker panel protection and a usable step in one — shields the lower body from rocks, ledges and ruts while making it easier to climb in and load gear.
Heavy-duty tubular steel with dimple die plating for strength, protection and a bold off-road look.
Steel grip protrusions built into the step surface for better footing.
High-clearance bolt-on design — stays tucked up for the trail instead of hanging down where it can catch.
Powder-coated finish to stand up to trail abuse and weather.
Sold as a pair — one slider for each side. Fits the 2021-2026 Ford Bronco 4-Door, all trims including Raptor.
Two official install videos on this page: the full install guide and a tech talk from the designers.
Step and Rock Slider for the 2021+ Ford Bronco 4-Door
Protection for the trail, a real step for everyday. Turn Offroad's ST1-M4 does both jobs on your 4-door Bronco.
Protection Where the Trail Hits First
Your Bronco's rocker panels take the first hit from rocks, ruts and ledges. The ST1-M4 is built from heavy-duty tubular steel with dimple die plating to take that contact for you and keep the lower body off the rock.
The high-clearance bolt-on layout keeps the slider tucked up for trail use, so you get protection without giving up the ground clearance you bought the Bronco for.
A Real Step, Not an Afterthought
This is not just a basic side step. The step surface has steel grip protrusions built in for better footing, which makes climbing in, loading gear and reaching the roof easier day to day.
It is a big help for passengers who are shorter or for anyone who just wants an easier way into a lifted truck.
Watch the Install
Turn Offroad's installation guide walks through putting the ST1-M4 on a 4-door Bronco, so you can see the process and hardware before you order.
Turn's Tech Talk
The designers explain how the ST1-M4 step slider is built and what sets it apart from a standard side step or a bare rock slider.
Who Is the ST1-M4 For?
4-door Bronco owners who want rocker protection and a step without buying both
Trail drivers who need ground clearance and a slider that stays tucked up
Anyone with passengers or kids who need an easier way up into a lifted Bronco
This Part Fits
2021-2026 Ford Bronco 4-Door
All trims: Base, Big Bend, Black Diamond, Outer Banks, Badlands, Heritage, Wildtrak, Everglades and Raptor
Turn Offroad part number ST1-M4. Sold as a pair: one slider for the driver side and one for the passenger side. Looking for a plain rock slider with no step? See the Turn Rock Sliders for the Bronco 4-Door. Vehicles, wheels, tires and other accessories shown in the photos are not included.
Which Broncos does this fit? It fits the 2021-2026 Ford Bronco 4-Door, all trims including Raptor. It is made for the 4-door only, not the 2-door.
Is this a step or a rock slider? Both. It protects the rocker panels like a rock slider and has a built-in step surface with steel grip protrusions for footing.
Will it hurt my ground clearance? Turn designed it as a high-clearance bolt-on that stays tucked up for trail use.
How hard is it to install? It is a bolt-on install. Watch the Turn Offroad installation guide on this page to see the full process before you order.
What is it made of? Heavy-duty tubular steel with dimple die plating and a powder-coated finish.
What is the difference from your plain Rock Sliders? The plain Turn Rock Sliders are all about rocker protection. The ST1-M4 adds a step surface so you also get easier access in and out.
Is it sold as a pair? Yes. One order covers both sides of your 4-door Bronco: the driver-side and passenger-side sliders. The step surface also makes getting in and out of a lifted 4-door easier for passengers.
