Upgrade your 2021-2026 Ford Bronco with the Turn Offroad RB4-M1 Swing-Out Tire Carrier with Lights, a frame-supported rear bumper and spare tire carrier system designed to take the weight of the spare tire off the Bronco's factory tailgate.
Instead of hanging a heavy spare from the tailgate, the RB4-M1 transfers the tire load into the rear bumper system. This makes it an excellent solution for Broncos running larger and heavier wheel and tire combinations while also adding rear protection, integrated lighting, a new third brake light, and a license plate relocation solution.
Best of all, the swing-out carrier is connected to the Bronco's tailgate so the tire carrier and tailgate open together with one hand. There's no separate carrier latch to open every time you need access to the cargo area.
Takes Spare Tire Weight Off the Bronco Tailgate
Larger off-road tires and wheels can add significant weight to the Bronco's factory tailgate-mounted spare tire carrier.
The Turn Offroad RB4-M1 addresses this by transferring the spare tire load into the frame-supported rear bumper system rather than asking the factory tailgate to support the additional weight.
This makes the RB4-M1 especially attractive for Bronco owners upgrading to heavier aftermarket wheels and larger spare tires.
One-Hand Tailgate & Tire Carrier Operation
Traditional swing-out tire carriers often require multiple steps to access the cargo area: unlatch the carrier, swing it out, and then open the vehicle's tailgate.
Turn Offroad takes a different approach.
The RB4-M1 connects the swing-out tire carrier to the Bronco's tailgate using race-grade heim joints, allowing the carrier to move together with the tailgate.
Open the Bronco tailgate and the tire carrier swings with it.
This provides convenient one-handed cargo access while retaining the strength and support of a bumper-mounted spare tire carrier.
Heavy-Duty Spindle Pivot System
The swing-out carrier uses a heavy-duty pivot system modeled after a vehicle-grade spindle.
High-quality bearings provide smooth movement, while the spindle is welded directly to the bumper and reinforced internally with gussets for strength and durability during repeated trail use.
This construction is designed to handle the additional forces created by carrying a spare tire over rough terrain.
Integrated Rear Lights Included
The RB4-M1 includes integrated rear lighting, maintaining useful rear visibility after replacing the factory bumper.
Turn Offroad also includes a new third brake light, helping maintain brake-light visibility with the spare tire mounted on the swing-out carrier.
License Plate Relocation Included
Relocating the spare tire and replacing the rear bumper also affects the factory license plate location.
Turn Offroad includes its RB1-LP1 License Plate Relocator with the RB4-M1 system, providing an integrated solution rather than requiring you to source a separate license plate mounting kit.
Retains the Factory Rear Camera
The Turn Offroad swing-out tire carrier is designed to maintain compatibility with the Bronco's OEM rear camera, allowing you to retain this important factory feature after installing the bumper and carrier.
Factory Sensor Compatible
The RB4-M1 is also designed to accommodate the Bronco's OEM rear sensors, helping preserve factory functionality while upgrading to a heavy-duty aftermarket rear bumper and tire carrier.
Retains Factory Tow Hitch Compatibility
Installing the RB4-M1 doesn't mean giving up the Bronco's factory tow hitch.
Turn Offroad designed the bumper and tire carrier system to remain compatible with the OEM tow hitch, allowing continued use of compatible towing and hitch-mounted accessories.
Accessory-Ready Design
The swing-out carrier incorporates mounting provisions for future accessories and add-ons.
This makes the RB4-M1 a strong foundation for an overland or trail build that may evolve over time with additional cargo or equipment mounting requirements.
