Frame-Mounted Strength. One-Handed Operation. Full OEM Sensor Compatibility.
The Ultimate Ford Bronco Spare Tire SolutionThe Turn Offroad Rear Bumper with Integrated Swing-Out Tire Carrier is the definitive upgrade for 2021+ Ford Bronco owners who demand heavy-duty performance without sacrificing daily usability. Designed to manage oversized spare tires, this system transforms your Bronco into an off-road powerhouse.
Engineered to protect your investment, this bumper transfers the massive weight of an aftermarket spare from the vulnerable tailgate hinges directly to the vehicle's frame. It’s built for the most rugged trails while maintaining a sleek, factory-plus aesthetic.
The Problem & The Solution:The Pain: Large spare tires cause factory tailgate sag, metal fatigue, and annoying rattles. Most heavy-duty carriers require two hands and multiple steps to open.
The Solution: Our RB4-M1 system uses race-grade heim joints to sync with your tailgate for seamless one-hand operation, while the frame-mounted spindle carries 100% of the load.
RB4-M1 Key Features: Engineered for the Trail
Transfers the spare tire's weight from the tailgate to the frame, preventing long-term structural stress and hinge failure.
The swing-out design integrates directly with the factory tailgate handle for effortless, synchronized opening.
Uses high-quality bearings and a gusseted, welded spindle for superior strength and smooth rotation over years of use.
Includes integrated bumper lights and a new 3rd brake light to keep your Bronco street-legal and visible on the trail.
Fully accommodates all factory backup cameras and parking sensors so you don't lose your Bronco's smart features.
Specifically engineered to work seamlessly with the OEM tow hitch for hassle-free towing and recovery.
Includes built-in mounting points for future accessories, allowing you to customize your overland setup as you grow.
Utilizes premium heim joints for a secure, precise connection between the tailgate and the carrier.
Heavy-Duty ConstructionPrecision-built for the most demanding off-roaders, the pivot system is modeled after heavy-duty vehicle spindles. Welded directly to the bumper and reinforced with internal gussets, it is designed to withstand the vibration and impact of rocky trails.
1-Hand Operation Direct Frame Mount 3rd Brake Light Incl. 100% OEM Sensor Fit
"After moving to 37-inch tires, my Bronco's tailgate started to groan. The Turn Offroad carrier completely solved the issue. The fact that it opens with the tailgate handle makes it feel like a factory option, but way beefier. The camera and sensors work perfectly, which was a huge concern for me."

2-Door Bronco (2021+) 4-Door Bronco (2021+)Future Proof: The accessory-ready design means you can easily add fuel cans, jacks, or recovery gear as your adventures evolve.
No. The RB4-M1 is specifically designed to accommodate all OEM cameras and sensors. You will maintain full functionality of your Bronco’s safety features.
Yes, the kit includes a new integrated 3rd brake light to ensure you remain street-legal, as oversized tires often block the factory unit.
Absolutely. This bumper is fully compatible with the OEM tow hitch, allowing you to tow trailers or use hitch-mounted accessories without modification.
Tailgate hinges are designed for factory tire weights. Adding 35-inch or 37-inch tires causes the sheet metal to flex and eventually crack. Frame-mounting places that stress on the strongest part of the vehicle.

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.
The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov

The wait time was more than I anticipated even after seeing the notification of long lead times. I have to give them props for giving some compensation for the excessive wait time. Having slightly larger holes would help with fitment. Had a hard time getting the front drivers side away from the pinch weld. Eventually had to use washers to add space away from the truck. Need to update pictures and instalation video for the new sliders they are now making
All packing and shipment were great, everything was there. I had to contract out the install because of arthritis, it took them two hours and looks perfect. Zero wind noise at any speed 0 to 100.
Absolutely love my new rack and roam cases. Appreciate the Sherpa crew as well for their hospitality while the installation was taking place.
Fit and finish is excellent. Looks great on the Bronco. No whistling noise at all, some additional wind noise over 60mph but not much different than it was without the rack. Assembly was not too difficult. Instructions and videos could be a little better.
The quality and dedication of the team at Sherpa is evident from the very first interaction with them, and is further proven in the product itself. This rack is well engineered, easy to assemble, easy to adjust, and holds up incredibly well with no loosening or rattling or shifting (even after over 200 miles of driving on poorly maintained roads). Currently operating with approximately 180 pounds of gear mounted on the bed rack and no issues at all so far. I expected the vibration to work the bolts loose over time, but every time I check they're all still snug. My only regret is that I didn't pull the trigger and get this rack sooner.
First of all, the team at Sherpa is full of passion for adventure and that passion shows in the quality of their products. This roof rack looks incredible and surprised me with it's sturdiness. No loosening of hardware, even after weeks of driving. Currently holding approximately 80 pounds of gear for everyday driving, plus an additional 110 strapped on top during a camping trip (and I even stood on top of the entire loadout). No warping, bending, twisting, or slipping. The fact that this matches the bed rack perfectly in height is the icing on the cake. Easily serves as a tie off for a tarp, rain fly, hammock, or whatever you need. Perfect for modular campsite setup and quick teardown.
I bought the Sherpa Crestone rack for my 2024 4Runner TRD Pro. Incredibly well-made and excellent design. Spend the extra , to get best roof rack in the market. You won’t regret it.
This is our first roof rack that we are going to use to put a RRT (roof top tent) on for back country trips. Well-built product that came with all the nuts, bolts and washers to complete the installation. Took about 1-1/2 to 2 hours install the rack. You will another person to help place the racks on top of the Jeep for final install. Overall, a great, well-built American product
Install was super easy. The quality was great. Customer service was quick to respond to any issues! I’ve already been getting compliments on it and what brand it is. This will be great for camping this year!
This is on my tundra absolutely solid rack looks fantastic extremely modular, which is why I went this route. I can use the whole rack when traveling and over landing then rock the chase rack only when the rest is not in use, I actually use the recovery traction board mounts for my shower room set up, which works amazingly just relocated the board somewhere shown in picture keep innovating TUWAand I’ll keep purchasing.
Good looking cat shields made of stainless steel with cooling holes. Priced well, easy install, no issues. Would buy again.
Great service from their staff. Robert help me through all the process with a request I had, he responded all emails in a timely manner and provided great help.
We received it within 3 days and installed the same day. Great awning and very well made.
the tent is very nice, comfortable and roomy.
Following the instructions was fairly easy. Its better to have second person to set it up. I really like the tent and the support that from ExtrailAuto. Really recommeded! Thanks
