Front Runner Slimline 3 Roof Rack Kit for Ford Bronco 4 Door Hard Top
Front Runner Slimline 3 Roof Rack Kit for Ford Bronco 4 Door Hard Top
✓ Front Roof Panels Remove With the Rack Fitted
The usual trade with a Bronco platform rack is giving up open-air driving. Not here. The front roof panels come off without removing the rack, so you keep both the platform and the reason you bought a Bronco.
A full-length platform on a Bronco normally means choosing between carrying gear and taking the roof panels out. The Dometic Front Runner Slimline 3 is the Bronco roof rack that does not ask you to choose, built specifically for the 4 Door U725 with the hard top.
This Ford Bronco roof rack is a 101.5 inch flat platform, 54 inches wide and 3.1 inches tall, which is 20% lower than the Slimline II and cuts drag, wind noise and fuel consumption accordingly. Slats move individually without dismantling the rack, dual T-slot channels take accessories at multiple pitches, and all four corners carry integrated tie-down points. Wiring for lights routes through concealed channels in the side profiles. Construction is heat-treated aluminium and high-strength 3CR12 stainless steel with a weather-resistant black powder-coated finish and stainless fasteners. Limited Lifetime Warranty.
Open-Air Driving, Loaded Rack
Shopping Bronco accessories usually means weighing what you gain against what you give up. The removable front roof panels are one of the main reasons people buy the vehicle, and most full-length racks quietly end that. Either the rack sits over the panels, or you are unbolting a platform every time the weather turns good.
This kit is engineered so the front roof panels can be removed with the Slimline 3 still mounted. Pull the panels, leave your awning, boards and cargo exactly where they are, and drive. It is the single most useful thing about this particular kit, and it is the reason to choose a Bronco-specific rack over a generic platform.
Move Slats Without Dismantling Anything
On the Slimline 3 you can add, remove, or shift individual slats without taking the rack apart. Fitting a new accessory no longer means pulling the tray down and rebuilding it around the mount. On a platform this long, where you may be arranging a tent, an awning, boards and a cargo box together, that flexibility saves real time.
Lower, Quieter, Cheaper to Run
Height is where this Front Runner roof rack separates itself. The Slimline 3 platform is 3.1 inches tall, a 20% reduction on the Slimline II, and over 101 inches of length that adds up.
Less Drag
A lower platform presents less frontal area, which shows up directly in fuel consumption on a long highway run.
Less Wind Noise
The most common complaint about any platform rack. Lowering the profile is the most effective fix.
Better Clearance
A Bronco is tall before you add anything. Every inch back matters in a parking garage.
Dual T-Slots and Staggered Insertion
Each slat carries dual T-slot channels with multiple staggered insertion points along its length, and slats can be set to different mounting pitches.
That means you can insert hardware at several points rather than threading it from one end, and you can change the spacing between slats to suit what you are mounting. A rooftop tent wants different pitch to a pair of recovery boards, and across 101 inches you will likely want both on the same rack.
Details That Show Up in Daily Use
Integrated Tie-Down Points
All four corners have built-in tie-down points compatible with Stratchits, Stratchit shorties, and other lightweight securing straps. No add-on brackets needed for the strapping most people do most often.
Concealed Wire Routing
Dedicated channels within the side profiles let you route wiring for lights and other electrical accessories out of sight. Corner sections include built-in pass-throughs and breakout tabs, so wires enter and exit cleanly rather than being cable-tied along the outside of the rack.
Full Accessory Compatibility
Every Front Runner top-mount accessory works with the Slimline 3, which on a platform this size is the point. Tent, awning, table, jack mount, boards, shovel, cans, lights, all on the same tray.
Built for Weather and Abuse
- Heat-treated aluminium for the tray and slats, keeping weight sensible across a full-length platform.
- High-strength 3CR12 stainless steel in the structural components, chosen for corrosion resistance in wet and salty environments.
- Weather-resistant black powder-coated finish over the top.
- Stainless steel fasteners as standard, not an upgrade.

Frequently Asked Questions
Can I still take my roof panels off?
Yes, and this is the main reason to choose this kit. The front roof panels can be removed with the Slimline 3 still mounted, so you do not have to unbolt the rack every time you want open-air driving. Your tent, awning and gear stay exactly where they are. Most full-length Bronco platforms make you choose between the two.
Will it fit my Bronco?
This kit is built for the Ford Bronco 4 Door (U725) with the hard top. It includes the vehicle-specific MSFB001 mounting system, so it is not a universal fit. Two door Broncos and soft top models need a different setup. Call us at 844-200-3979 with your year and configuration if you want it confirmed before ordering.
What is different about the Slimline 3?
Two things mainly. The platform is 20% lower than the Slimline II at 3.1 inches, which cuts drag, wind noise and fuel use. And the slats are individually movable, so you can add, remove or shift them without dismantling the rack. The Slimline 3 also adds integrated corner tie-downs and concealed wire routing through the side profiles.
Can I fit a rooftop tent and other gear together?
That is what a 101.5 inch platform is for. There is room for a tent plus an awning down one side, boards, a shovel and cans, and the adjustable slat pitch lets you set spacing to suit each. Dometic does not publish a load rating for this kit, so check your tent's weight against your Bronco's roof load limit, and call us at 844-200-3979 if you want help working it out.
Can I run wiring for lights through it?
Yes, and cleanly. Dedicated channels inside the side profiles carry wiring for lights and other electrical accessories out of sight, and the corner sections have built-in pass-throughs and breakout tabs so wires enter and exit where you need them. No cable ties along the outside of the rack.
Will my existing Front Runner accessories fit?
The Slimline 3 is compatible with all top-mount accessories in the Front Runner range. If you are moving over from a Slimline II and have accessories that rely on the older slat spacing, it is worth checking those specifically before you order. Call us at 844-200-3979 with what you are running and we will confirm.
