Ford Bronco Step-Slider Fitment
The Turn Offroad 4-door Step-Slider combines a Ford Bronco side step with a stronger rock-slider style structure. It fits 2021-2027 4-door Broncos, including Bronco Raptor.
Best For
4-door Bronco and Bronco Raptor owners who want one part to work as both a usable side step and trail-focused rocker protection.
Step-Slider Construction
Heavy-duty tubular steel, dimple-die plating, and stronger mounting brackets form the slider base. A removable textured step bolts on top, giving you easier daily entry without giving up the tighter trail-oriented structure underneath.
Rocker Panel Protection
The slider covers the pinch seam and helps keep rocks and ledges away from the rocker panel. Because the step section can be removed, you can run the cleaner slider profile when trail clearance matters more than daily convenience.
Step-Slider vs. Side Steps & Rock Sliders
This sits between a dedicated side step and a dedicated rock slider. Choose it if you want both jobs from one part. If you only need entry help, a side step is simpler. If maximum trail protection is the only goal, the Zero Series rock slider is the more focused choice.
Installation
Installation is bolt-on and uses heavier brackets than the factory rail setup. No cutting or drilling is required.

Questions
Is this a rock slider or a step?
It is both. The ST1-M4 is a step-slider built to add rocker protection while still giving passengers a usable step.
Do the steps come off?
Yes. The step assemblies are removable so you can run the slider cleaner for trail use.
Does it fit 2-door Broncos?
No. ST1-M4 fits 2021-2027 Ford Bronco 4-door models only.
Does it cover the pinch seam?
Yes. The design helps cover the pinch seam while improving side protection and entry access.
Is drilling required?
No. This is a fully bolt-on upgrade.
