A rocker panel repair on a Ford Bronco runs $500 to $1,500 at a body shop. A set of running boards or rock sliders costs $649. Most Bronco owners find that out in the wrong order.
The rocker panels are the painted steel sections running along the bottom of your doors, between the front and rear wheel wells. They sit low. They are exposed. On the 2021-2026 Ford Bronco they are completely unprotected from the factory. One bad line on a trail, one parking lot door swing, one curb catch — and you are looking at a repair bill that a set of running boards or rock sliders would have made impossible.
This guide covers every running board, rock slider, side step, and step-slider option for the 2021-2026 Ford Bronco. What each one actually does, what it costs, who it is built for, and which one belongs on your specific truck. By the end you will know exactly what to order.
Which Ford Bronco Running Board, Rock Slider, or Side Step Is Right for You?
If you already know your use case, here is the direct answer. If you want to understand the why behind each recommendation, keep reading — the next section breaks down the differences that actually matter before you spend anything.
You trail run regularly on rocky terrain: The DV8 FS-15 Series rock sliders are the right call. Frame-mounted, full-length, built from 3.5mm to 5mm steel depending on door config, rated for hi-lift jack use. $849.99 for the 2-door, $1,099.99 for the 4-door. Nothing else in this lineup matches the protection level for hard trail use.
You want trail protection and a step for daily use: The Turn Offroad Step-Slider, also called rock slider steps or rock rail steps depending on who you ask. Slider construction with a removable step platform. Run the step Monday through Friday, pull four bolts and remove it before you hit the trail. $649 for the 2-door, $899.99 for the 4-door. The only product in the lineup that does both jobs without compromise.
You daily drive and want running board-style step protection: Side steps. The DV8 OE Plus running boards at $699.99 (2-door) or $799.99 (4-door) for a factory-matched look with real grip teeth. The Turn Offroad side steps at $649.99 for 4-door owners who want pinch weld coverage at the lowest price point in the lineup.
You rock crawl or run serious technical terrain: DV8 FS-15 Series, full stop. And pair them with skid plates underneath. Rock crawling without frame-mounted sliders is the fastest way to turn a trail day into a tow truck call.

Bronco Running Boards, Rock Sliders, Rock Rails, Side Steps — What Do These Terms Actually Mean?
This is where most buyers get confused. Ford, the aftermarket, and dealers all use different words for the same product category. Here is what each term actually means so you are not comparing the wrong things.
Running boards — the wide, flat step platform that runs below the doors on trucks and SUVs. Think of the step boards on a Ram 1500 or an F-150 — a broad shelf you plant your foot on before stepping up into the cab. The Bronco aftermarket calls these side steps, but buyers coming from truck ownership search for running boards. Same product, different name.
Side steps — the Bronco aftermarket's term for running boards. Body-mounted step platforms with light rocker coverage. Built for cab access first, trail protection second. When you search "bronco side steps" or "bronco running boards" you are searching for the same category of product.
Rock sliders — the aftermarket term for frame-mounted steel protection running along the rocker panel. Some people shorten this to just "sliders." The name comes from what they do: when the truck leans into a rock on the trail, the slider contacts the rock first and slides off it rather than catching. Frame-mounted means the bolts go into the truck's frame, not the body. Completely different mounting method and capability from running boards.
Rock rails — Ford's own marketing term for what the aftermarket calls rock sliders. If your Bronco came with factory rock rails on a Badlands or Wildtrak trim, you have body-mounted steel tubes from Ford. Same concept as aftermarket sliders, different mount point, different capability. More on that distinction below.
Rock rail steps and rock slider steps — the search term most people land on when they want both jobs done by one product. A slider or rail with a step built into it. That is exactly what the Turn Offroad Step-Slider is, even though the product name does not use either phrase. If you searched for rock rail steps or rock slider steps to find this page, the Step-Slider is the product you are actually looking for.
Step-sliders — a hybrid category. Slider construction and mounting with a removable step platform bolted onto it. Trail protection and daily running board usability in one product. Turn Offroad makes the only version we carry for the 2021-2026 Bronco.
Rocker guards — another term for the same general category, used by buyers thinking about the rocker panel protection angle rather than the step or trail angle. Whichever term gets you here, you are looking at the same lineup.
Step bars and nerf bars — other terms buyers use when searching for the same running board and side step category. Step bars, nerf bars, step rails, hoop steps — all refer to side-mounted step accessories. On the 2021-2026 Bronco specifically, every product in this lineup covers what those searches are looking for.
Now that the vocabulary is clear, here is the one technical distinction that actually determines which product is right for your truck.
Frame-Mounted vs Body-Mounted: The Difference That Actually Matters on the Trail
Every running board, rock slider, side step, and rock rail on the 2021-2026 Ford Bronco mounts one of two ways. Frame-mounted or body-mounted. This single distinction determines whether the product can actually protect your truck on the trail or just cover the rocker panel visually.
Here is what each one means in plain terms.
Body-mounted means the mounting brackets bolt into the body of the truck. The body is the steel shell that sits on top of the frame — the doors, the floor, the cab structure. It is strong enough to hold a running board under normal use. When a body-mounted product takes a trail impact, that load goes into the body panels at the mount points. On a light brush strike or a parking lot nudge, that is fine. On a hard rock strike where the truck leans full weight into an obstacle, that load path transfers to body panels that are not designed to absorb it. You get bent body mounts, cracked panels, and deformed mounting points over time.
Frame-mounted means the mounting brackets bolt directly to the truck's frame — the steel ladder that runs the full length of the vehicle underneath everything. The frame is the strongest structural member on the truck. When a frame-mounted slider takes a hard trail impact, the load goes straight to the frame. The body panels are not involved. The slider takes the hit and transfers it to the structure built to handle it.
There is one more thing frame-mounted sliders do that body-mounted running boards cannot. They support the full weight of the vehicle as a hi-lift jack point.
A hi-lift jack is a tall mechanical floor jack — picture a 4-foot steel rail with a ratcheting carriage that cranks up notch by notch — that off-road Bronco owners use to lift the truck for tire changes, recovery, or unsticking a wheel from a ledge. Frame-mounted sliders provide a solid anchor point along the entire rocker panel length. Body-mounted running boards do not. Trying to jack from a body-mounted step puts load into body panels that flex, and the jack slips. That is a dangerous situation on the trail.
The practical takeaway: if your Bronco goes off-road in conditions where the truck might lean into anything, you want frame-mounted sliders. If you daily drive and want an easy step for cab access, body-mounted running boards and side steps are adequate, lighter, and significantly less expensive.
Now here is every option in the lineup, broken down so you know exactly what you are buying.
The Best Ford Bronco Rock Sliders for Trail Use: DV8 FS-15 Series
The DV8 FS-15 Series is the trail protection standard in the Bronco aftermarket. Frame-mounted, full-length, built from heavier steel than anything else in this lineup. If you run rocky terrain, rock gardens, ledges, or anything where the truck is going to lean hard into an obstacle, these are what go on the truck. Not a close decision.
DV8 FS-15 Rock Sliders — Ford Bronco 2-Door: $849.99
Built from 3.5mm steel tube and 4mm steel plate in a boxed mounting design that runs the full length of the rocker panel from wheel well to wheel well. Full-length matters. A slider that stops short of the front or rear wheel well leaves the corners of your rocker exposed — and corners are exactly where rocks and ledges catch first on a trail.
Three-point frame mount transfers every hit directly to the frame. No body panel involvement. Clears up to 38-inch tires so 2-door builds running a lift and bigger rubber have no fitment concerns. Bolt-on with factory hardware. No cutting. No drilling. DV8 rates the install at 1 hour with basic hand tools.
Fits: 2021-2026 Ford Bronco 2-door, all trims
Does NOT fit: 4-door. Does NOT fit Bronco Sport.
Before you order: Factory rock rails or OEM sliders must be removed before installation.
DV8 FS-15 Rock Sliders — Ford Bronco 4-Door: $1,099.99
The 4-door rocker panel is longer so the slider needs more structure to stay rigid across its full length. DV8 addressed this with 3mm steel tube, 5mm steel plate, and a 3-point frame mount with large center supports. Those center supports are the detail most buyers overlook. Without them a long slider flexes in the middle under load. The center supports eliminate that entirely.
Fully bolt-on. No cutting, no drilling, no frame or body modifications. DV8 rates the 4-door install at 3 hours due to the additional mount points. Finished in micro-texture black powder coat. Sold as a pair.
Fits: 2021-2026 Ford Bronco 4-door, all trims except Raptor
Does NOT fit: 2-door. Does NOT fit Raptor. Does NOT fit Bronco Sport.
Before you order: Not compatible with DV8 Pinch Weld Covers (SRBR-03).
The FS-15 is the answer for anyone who wheels hard. But what if you want slider-level protection and a running board you can actually use every day? That is a different product entirely.
The Best Step-Slider for Ford Bronco Owners Who Want Both: Turn Offroad
The Turn Offroad Step-Slider is the product most Bronco owners do not know exists until they are already deep in the research. It is not a running board with slider branding. It is actual slider construction with a removable step platform bolted to it. People searching for rock rail steps or rock slider steps end up here, even though Turn Offroad does not use either term in the product name.
The body of the Step-Slider is frame-mounted heavy-gauge steel tube with pinch weld coverage. Built to take trail impacts the same way a dedicated rock slider does. Mounted on the outside is a step platform with steel grip protrusions — small raised metal points that bite into the sole of your boot and keep your foot planted whether it is dry, wet, or caked in mud.
Pull four bolts. Step platform comes off in under two minutes. What is left is a clean, high-clearance slider profile for the trail. Put it back on for the drive home. No compromise on either end.
Turn Offroad Step-Slider — Ford Bronco 2-Door: $649
Heavy-duty tubular steel with dimple-die plating, .160-wall tubing, and mounting brackets in 1/4-inch and 3/16-inch steel. Sits high against the body to minimize ground clearance loss. Mounts in the factory slider location and uses stronger brackets than the OEM setup it replaces. At $649 it is the lowest-priced rocker protection option in the entire lineup.
Fits: 2021-2026 Ford Bronco 2-door only
Does NOT fit: 4-door. Does NOT fit Bronco Sport.
Turn Offroad Step-Slider — Ford Bronco 4-Door: $899.99
Same construction scaled to the 4-door's longer rocker panel. The removable running board step is especially valuable on lifted 4-door builds where rear passengers are stepping up into a truck that sits 2 to 4 inches higher than stock. Without a step, getting into the back seat of a lifted 4-door Bronco requires a serious leg raise every single time. The step fixes that. Trail days, pull it off. Everything else, leave it on.
Fits: 2021-2026 Ford Bronco 4-door only
Does NOT fit: 2-door. Does NOT fit Bronco Sport.
If the trail is not part of the picture at all and you want something that looks clean, steps easily, and adds light rocker protection for daily driving — that is a different category. Here is what Bronco running boards and side steps actually look like on the 2021-2026 Bronco.
The Best Ford Bronco Running Boards and Side Steps for Daily Drivers
Running boards and side steps are the right call when the Bronco is primarily a daily driver. Body-mounted, lighter than frame-mounted sliders, and built around making cab entry easy rather than surviving repeated trail impacts. They still add real rocker panel coverage and they look right on the truck.
DV8 OE Plus Running Boards — Ford Bronco 2-Door: $699.99
Built to look like something Ford designed. The OE Plus running boards match factory Bronco trim lines closely enough that most people cannot tell at a glance they are aftermarket. Steel tube supports topped with steel step plates featuring bike pedal-style grip teeth — small raised metal points similar to the pins on a mountain bike pedal that grip the sole of your boot on wet or muddy days.
Multi-mount design spreads load across multiple contact points. Clears 38-inch tires. Body and pinch weld mounted, no drilling required. Install rated at 1 hour. Micro-texture black powder coat finish. Sold as a pair.
Fits: 2021-2026 Ford Bronco 2-door, all trims
Does NOT fit: 4-door. Does NOT fit Bronco Sport.
Before you order: Factory rock rails must be removed before installation.
DV8 OE Plus Running Boards — Ford Bronco 4-Door: $799.99
The 4-door version uses 2mm steel tube supports with 3mm and 5mm steel step plates and the same grip teeth as the 2-door. Engineered specifically for 4-door trim levels. Bolts directly to the Bronco using provided hardware, no modifications, no drilling. Micro-texture black powder coat matches factory trim. Sold as a pair.
Fits: 2021-2026 Ford Bronco 4-door, all trims
Does NOT fit: 2-door. Does NOT fit Bronco Sport.
Turn Offroad Side Steps — Ford Bronco 4-Door: $649.99
The lowest-priced running board option in the 4-door lineup at $649.99. The boxed steel design covers the pinch weld and keeps the profile tight to the body. The step surface uses CNC-cut openings — think of a metal drain grate, rectangular cutouts with steel rails between them — so mud and debris fall straight through rather than packing in. 3-stage nano-textured powder coat over industrial primer. Clears 38-inch tires. Bolt-on with included hardware.
Fits: 2021-2026 Ford Bronco 4-door only
Does NOT fit: 2-door. Does NOT fit Bronco Sport.
Seven products, three protection levels, two door configs. Before you order any of them, here is the full lineup side by side and the fitment notes that can save you a return shipping headache.
Every Ford Bronco Running Board, Rock Slider, and Side Step by Price
The full lineup at a glance, sorted low to high within each door config.
2-Door Ford Bronco:
- Turn Offroad Step-Slider — $649 — frame-mounted slider with removable step, lowest price in the lineup
- DV8 OE Plus Running Boards — $699.99 — body-mounted daily driver running board with grip teeth
- DV8 FS-15 Rock Sliders — $849.99 — frame-mounted full trail protection, hi-lift jack rated
4-Door Ford Bronco:
- Turn Offroad Side Steps — $649.99 — body-mounted running board with pinch weld coverage
- DV8 OE Plus Running Boards — $799.99 — body-mounted factory-look running board with grip teeth
- Turn Offroad Step-Slider — $899.99 — frame-mounted slider with removable running board step
- DV8 FS-15 Rock Sliders — $1,099.99 — frame-mounted full trail protection, hi-lift jack rated
The price spread directly reflects protection level and mount strength. Every dollar up the list buys more steel, more mount points, and more capability. None of these products is wrong. They serve different builds and different owners.
Fitment Notes: What to Confirm Before You Order Any Bronco Running Board or Rock Slider
2-door vs 4-door: The most common source of wrong orders in this category. The 2-door and 4-door Bronco have different rocker panel lengths and different frame mounting points. A 2-door product will not physically mount on a 4-door. Confirm your door config before every order.
Sasquatch Package: The Sasquatch Package changes wheel offset, tire size, and suspension height but does not affect running board or rock slider mounting points. All seven products are compatible with Sasquatch-equipped 2021-2026 Ford Broncos across all trims.
Bronco Raptor: The Raptor runs a wider front track and different body dimensions than every other Bronco trim. The DV8 FS-15 4-door explicitly does not fit the Raptor. Contact us directly before ordering any product in this lineup if you own a Raptor.
Factory rock rails and OEM sliders: The DV8 FS-15 2-door and DV8 OE Plus Running Boards 2-door both require removal of factory rock rails or OEM sliders before installation. The Turn Offroad Step-Sliders mount in the factory slider location, so factory sliders come off as part of the install. The 4-door FS-15 uses factory mounting points throughout.
Ford Bronco Sport: Not a single product in this lineup fits the Ford Bronco Sport. The Bronco Sport is an entirely different vehicle built on a car-based unibody platform. It shares a name with the full-size 6th generation Bronco and nothing else.

Frequently Asked Questions About Ford Bronco Running Boards and Rock Sliders
What is the difference between Ford Bronco running boards and rock sliders?
Running boards and side steps are body-mounted step platforms built for cab entry with light rocker coverage as a secondary benefit. Rock sliders are frame-mounted steel tubes that protect the rocker panel from trail impacts and support the full vehicle weight as a hi-lift jack point. The mounting method is the key difference. Frame-mounted products transfer trail impact load to the frame. Body-mounted running boards transfer it to the body panels. For trail use, frame-mounted rock sliders are the correct product. For daily driving, body-mounted running boards and side steps work well and cost less.
Are Ford Bronco rock rails the same as rock sliders?
Same concept, different product. Ford's factory rock rails are body-mounted steel tubes that come on certain trims like the Badlands and Wildtrak. Aftermarket rock sliders are typically frame-mounted, built from heavier steel, and designed for harder trail use. A frame-mounted aftermarket slider transfers trail impacts to the frame rather than the body panels. For serious off-road use, aftermarket frame-mounted sliders are the meaningful upgrade over factory rock rails.
What are rock rail steps or rock slider steps on a Ford Bronco?
Both terms describe the same product: a frame-mounted slider with a removable or built-in step platform bolted onto it. On the 2021-2026 Bronco, the Turn Offroad Step-Slider is exactly that product, even though Turn Offroad does not use either phrase in the official product name. It gives you slider-level trail protection with a usable step for daily driving, and the step comes off in minutes for trail days.
Do Ford Bronco running boards and rock sliders fit all trims and model years?
All seven products in this lineup fit the full 2021-2026 Ford Bronco range across all standard trims for their respective door config. The DV8 FS-15 4-door does not fit the Bronco Raptor. The Sasquatch Package does not affect fitment on any product here. The most important variable is always door config — 2-door products do not fit 4-door trucks and vice versa.
How much do Ford Bronco running boards and rock sliders cost?
Running boards and side steps start at $649.99 for the Turn Offroad 4-door side step and go to $799.99 for the DV8 OE Plus 4-door. Rock sliders run $649 for the Turn Offroad Step-Slider on the 2-door up to $1,099.99 for the DV8 FS-15 on the 4-door. Professional installation adds $100 to $300 depending on the product and your local shop rate. All products in this lineup are bolt-on with no cutting or drilling required, so a DIY install is realistic for most owners.
