This sleek bumper is made from CNC cut ¼” plate steel (or 3/16″ steel if you so choose) and offers the best body protection and style for your full-size Bronco.  With its easy bolt-on installation that requires no welding or drilling, it’s hard to beat. Our design wraps around the rear corners to provide our quality protection and includes a 2” unrated receiver hitch (CAN BE ORDERED WITHOUT RECIEVER). Our unrated receivers are only capable of pulling the stock recommended weight for your Bronco.* This very durable and modern design comes with access points for use of a hi-lift jack cut into the bumper (this is for USE of a hi-lift jack not for jack storage). Its angular design also makes it easy to use a tow hook or you can add a set of D-ring tabs for the ultimate tow points.

* This statement applies to our 1/4″ bumper. If you plan on using the receiver to tow, please use your best judgement. Our hitches are unrated but can support the stock towing capacity of a Bronco (we do not claim this on f-series trucks) and our bumper mounting system bolts on the vehicle frame. Small and lightweight single axle trailers are typically safe to tow behind your Bronco. If you tow something that you shouldn’t be towing with your Bronco, you could seriously injure yourself or others should something fail. We are not liable for any damage, loss or injury.


  1. If you have an XLT, you may run into an issue with the tailgate trim hitting the cam bail when the tailgate is open. To remedy this, you can run a cable stop (approx 17″) on your tailgate.  Otherwise you will have to notch the trim.
  2. There have been several people who have successfully put these bumpers on pickup trucks. Please keep in mind that these bumpers are made for the Ford Bronco and the stock axles they come with. These bumpers will fit on F-Series pickups however the frame span is not the same, nor is the bolt pattern for the spare tire and it may require moderate to heavy modification to install the bumper properly.  You will have to order the correct wheel plate to make the spare tire fit. 8 lug wheel plates are an additional $45. The frame mounts will also need to be ordered unwelded and you will need to modify/create a custom bracket for mounting. We DO NOT recommend putting these bumpers on pickup trucks unless you have an experienced fabricator contracted for the job. We also DO NOT provide installation assistance in this case.
  3. Interior dimension between two side wings is 76″
