In This Guide
A 2-door Bronco and a 4-door Bronco don't use the same rock sliders. The two body styles sit on different wheelbases, so a slider built for one won't line up on the other. This guide breaks down why, and where the frame mounting points differ.
Why Wheelbase Changes Rock Rail Fitment
2-Door Wheelbase
The 2-door Bronco rides on a shorter wheelbase, so the distance between the front and rear frame mounting points is shorter. A rock slider built for the 4-door body won't reach both mounting points on a 2-door frame. Turn Offroad's 2-door slider runs 67 inches to match this shorter span.
4-Door Wheelbase
The 4-door Bronco's longer wheelbase spaces its frame mounting points farther apart. A slider built for the 2-door body would leave a large gap unprotected in the middle of the rocker panel. Turn Offroad's 4-door slider stretches to 78 inches, 11 inches longer, to close that gap.
Why Mounting Points Don't Match
Every 2-door and 4-door slider is built to one body length only. Mount a 2-door slider on a 4-door Bronco and the rear section of the rocker panel is left exposed. Try the reverse, and the 4-door slider's mounting brackets won't line up with the 2-door's shorter frame points at all.
Even trimming a slider down wouldn't fix this. The brackets are welded to land on specific points along the frame rail, and cutting the tube doesn't move those points to where a shorter frame needs them.
2-Door Options
For 2-door Broncos, we carry the Turn Offroad Zero Series, a straight slider built for trail protection, the Turn Offroad Step-Slider "Stider", which adds a removable step section to the same design, and the DV8 FS-15 Series, a direct bolt-on that requires removing the factory sliders or rock rails first.
4-Door Options
4-door Broncos use the same three lines, sized for the longer body: the Turn Offroad Zero Series, the Turn Offroad Step-Slider "Stider", and the DV8 FS-15 Series V2, which isn't built to run alongside DV8's own pinch weld covers (SRBR-03).
What About the Bronco Raptor?
The Bronco Raptor's wider track and flared fenders change its rocker panel dimensions compared to standard Broncos. None of the sliders above are built for the Raptor, and DV8's 4-door FS-15 V2 specifically excludes it. If you own a Raptor, check with us before ordering a standard-width slider, since it will not fit correctly.
See our rock sliders and side steps collection for the full lineup, or read What Are Rock Rails on a Ford Bronco? if you're still deciding whether you need one.
FAQ
Can I put 4-door rock sliders on a 2-door Bronco?
No. The 4-door sliders are built to a longer length and won't match the 2-door's shorter frame mounting points.
How much longer are 4-door rock sliders than 2-door?
Turn Offroad's Zero Series runs 78 inches on the 4-door versus 67 inches on the 2-door, a difference of about 11 inches to match the longer wheelbase.
Why can't a slider just be trimmed to fit the other body style?
Cutting the tube doesn't move the mounting brackets. They're welded to land on specific points along the frame rail, and those points don't shift just because the slider got shorter.
Does the Bronco Raptor use the same rock sliders as a standard 4-door?
No. The Raptor's wider track changes its rocker panel dimensions, and none of the standard 4-door sliders we carry are built for it.
Which rock slider works as a step too?
Turn Offroad's Step-Slider "Stider" is built to work as both a rock slider and a step, available in both 2-door and 4-door lengths.
Do I need to remove the factory rock rails first?
DV8's FS-15 Series requires removing the factory sliders or rock rails before installation. Check each product's fitment notes before ordering.
