Blue Ox is known internationally for recreational and commercial towing products, manufacturing in Pender, Nebraska since 1925. The line covers tow bars and vehicle-specific baseplates for flat towing behind a motorhome, sway control and weight distributing hitches, supplemental braking accessories and towing wiring, backed by patented designs and long-standing customer service.
Blue Ox has manufactured since 1925 and is recognised internationally for towing products and customer service. The company operates from Pender, Nebraska, where it grew out of Automatic Manufacturing Co., a business that started with cattle oilers and developed into agricultural equipment, tractor accessories and trailer towing hardware. That agricultural engineering heritage still shows in how the towing products are built, and the company holds patents across weight distribution, fifth wheel and tow bar designs.
Flat towing is the discipline Blue Ox is best known for. Towing a car with all four wheels on the ground behind a motorhome demands a system that stays rigid under braking, articulates properly over uneven ground, and connects to the towed vehicle at points strong enough to take the load. Blue Ox tow bars handle the first two, with self-aligning arms that latch under tension and release without a struggle when the load is off them. Vehicle-specific baseplates handle the third, engineered per make and model to tie into structural mounting points behind the fascia.
The wider flat towing range covers supplemental braking systems, safety cables and the accessories that make a complete legal setup, along with baseplate wiring and dinghy towing harnesses that pass lighting signals to the towed vehicle without back-feeding its electrical system.
For conventional trailer towing, Blue Ox weight distributing hitches with integrated sway control transfer tongue load onto the tow vehicle's front axle and resist the yaw that crosswinds and passing trucks induce.
The company describes its foundation as customer service, designing around what owners actually ask for, and it runs an RV park adjacent to the factory where customers can stay. Sister operations at the same Nebraska site include Automatic grain roller mills and MAD-RAMPS pivoting ramp systems.

The BX2621 is a removable baseplate manufactured by Blue Ox designed specifically for 2010-12 Ford Flex Limited Ecoboost vehicles. It is used to attach a tow bar for towing another vehicle. The baseplate features removable attachment tabs and is designed to mount to the vehicle's frame rails.
No. Due to the design of the removable tabs on the BX2621, the RangeFinderII tow bar cannot be used with this baseplate.
Most adapters cannot be used with the BX2621 baseplate due to its removable tab design. The exceptions are the BX8833 and BX88151 adapters, which are compatible.
Required tools include: 10MM socket, 12MM socket, 7/16" wrench, 9/16" wrench, large vise grip, reciprocating saw, flat screwdriver, Phillips screwdriver, utility knife, torque wrench, tape measure, drill, 1/4" drill bit, 13/32" drill bit, 1-1/4" hole saw, and Loctite Red. A 5.5MM socket is also needed for removing fasteners during disassembly.
The kit includes: 4 nut plates with 14" wire (3/8"-16), 1 baseplate, 2 attachment tabs with holes, 2 spacers, 1 breakaway bracket, 1 hex head bolt (1/4"-20 x 3/4"), 2 round slotted head screws (#10-32 1/2"), 8 hex head bolts (3/8"-16 x 1-1/4"), 2 hex head bolts (3/8"-16 x 1-1/2"), 2 self-tapping screws (#10-16 x 1"), 2 self-drilling screws (#12-14 x 1"), 2 hex nuts (#10-32), 6 hex nuts with nylon insert (3/8"-16), 1 hex nut with nylon insert (1/4"-20), 6 flat washers (3/8"), 4 lock washers (3/8"), 2 lock washers (#10), 2 Class IV safety cables (36"), 4 quicklinks (1/2"), and 2 black cap plugs.
The BX8848 4-Diode Wiring Kit is recommended for this vehicle, but the manual does not state it is required. You should consult with your Blue Ox dealer or the general instructions for the baseplate to determine if it is necessary for your specific towing setup.
Yes. The front fascia and metal bumper must be removed during installation. The removal process involves removing bolts and pushpins from the grille, fascia, and bumper, as well as drilling out spot welds on the bumper.
Yes. Blue Ox towing products are intended to be installed by Blue Ox Dealers who are familiar with the products and have the equipment and knowledge necessary to do "fit work". Blue Ox Dealers can be found at www.blueox.com or by contacting the Technical Service Department at (402) 385-3051.
Yes. Drilling is required. You will need to drill out two spot welds on each side of the bumper using a 1/4" drill bit, and drill two holes on the bottom of the baseplate and three holes on the side of the baseplate using a 13/32" drill bit.
Yes. Trimming is required. You must cut out horizontal pieces from the fascia using a hacksaw blade to allow the attachment tabs to come through. If installing the optional breakaway bracket, an additional horizontal piece must be cut from the fascia to accommodate it.
Yes. Using a vise grip, you must bend the two inside tabs on the frame rail out flat with the frame. On top of the frame rail, bend the center ribbing toward the radiator approximately 6" back from the end. After mounting the baseplate, bend the two tabs back. These modifications are necessary to accommodate the baseplate and may be permanent depending on the vehicle's tolerances.
The manual notes that dimensional variations between otherwise identical vehicles can be considerable. Minor adjustments may include filing a hole slightly, bending electrical rods, or bending end plates to tailor the baseplate to your specific vehicle.
According to the bolt torque specifications table, 3/8"-16 Grade 5 bolts should be torqued to 33 foot-pounds. However, the manual references applying torque "according to the torque chart on the front page of these instructions or on page 3 of the baseplate towing general instructions," suggesting you should verify the specific torque for each bolt location with the complete general instructions.
The attachment tab height is 24-1/4" and the attachment tab width is 24".
You will need a 1/4" drill bit to drill out the spot welds on the bumper, a 13/32" drill bit to drill the mounting holes for the baseplate on the frame rails, and a 1-1/4" hole saw for other drilling tasks.
If your vehicle is equipped with a temperature sensor on the top of the bumper, unclip it and move it aside during bumper removal (Step 6). After the bumper is reinstalled, relocate the temperature sensor on the passenger's side to the bottom of the bumper using existing holes (Step 13).
The electrical plug should be installed on the front of the fascia after the fascia has been cut to accommodate the attachment tabs (Step 15). Ensure that all electrical connections are plugged in properly and functioning before installing the fascia.
Failure to read and follow the installation instructions could result in separation of the towed vehicle from the tow bar, causing property damage, loss of towed vehicle, personal injury or death. This is why professional installation by a Blue Ox Dealer is strongly recommended.
No. Do not use the towed vehicle for storing luggage, equipment, etc. This may cause you to exceed the towing capacity of the tow bar, baseplate, and its accessories.
If the baseplate is in an accident, it must be replaced. Do not use it again. An accident can cause unseen damage and using it again could result in more damage or serious injury. Do not use the baseplate if it is damaged or missing parts.
The permanent baseplate safety cables must be connected from the baseplate to the frame rail or cross member of the vehicle's frame. Attach the cables to the provided convenience link on the baseplate and secure them to a solid piece of the vehicle's frame. Do not mount the cables against wires, hoses, or brake lines. The cables should remain installed as long as the baseplate is installed on the vehicle.
It is the owner's responsibility to inspect all towing equipment for cracked welds, missing or worn parts, and loose bolts before each towing trip. Be sure to use Loctite Red on all bolts and tighten them to the recommended specifications.
Yes. Remove the attachment tabs when not in use, if applicable. This helps protect them and reduces wind resistance when the baseplate is not being used for towing.

Yes, the BX2621 is designed specifically for 2010-12 Ford Flex Limited Ecoboost vehicles.
No, the RangeFinderII tow bar cannot be used with the BX2621 due to its removable tab design.
You will need sockets (10MM, 12MM, 5.5MM), wrenches (7/16", 9/16"), vise grip, reciprocating saw, screwdrivers, utility knife, torque wrench, tape measure, drill with bits (1/4", 13/32"), 1-1/4" hole saw, and Loctite Red.
Yes, the front fascia and metal bumper must be removed during installation.
Yes, drilling is required to mount the baseplate to the frame rails and to remove spot welds from the bumper. Trimming of the fascia is required to accommodate the attachment tabs.
3/8"-16 Grade 5 bolts should be torqued to 33 foot-pounds. Use Loctite Red on all bolts before tightening.
The baseplate must be replaced and cannot be reused. Do not use a damaged or incomplete baseplate.
Inspect all towing equipment for cracked welds, missing or worn parts, and loose bolts. Ensure all bolts are tightened to specification with Loctite Red.
The manual notes that dimensional variations between otherwise identical vehicles can be considerable. Minor adjustments may be necessary to tailor the baseplate to compensate for auto manufacturer's tolerances. These adjustments may include filing a hole slightly, bending electrical rods, or bending end plates. If the baseplate cannot be leveled with these minor adjustments, contact Blue Ox Technical Service at (402) 385-3051.
Ensure that all electrical connections are plugged in properly and functioning before installing the fascia. If connections are not functioning, check that all plugs are fully seated and that no wires are damaged or pinched. Do not proceed with fascia installation until all electrical connections are verified to be working properly.
