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 BlueOx Tow Bar Base Plate, Front Mount, RV Flat Towing for Select, TOYOTA PICKUP (Part #FDRWBX3721) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The BX3721 baseplate is designed for 1989-95 Toyota 4WD Pick-Up and 1990-95 Toyota 4-Runner models. If your vehicle is within these model years and body styles, the baseplate is compatible. However, dimensional variations between otherwise identical cars can be considerable, so you may need to file or drill a hole slightly to allow a bolt to clear during installation.
Yes, the BX3721 is compatible with vehicles equipped with a skid plate. The skid plate must be removed during baseplate installation, then remounted afterward. The baseplate cross angle will sit between the front skid plate mounts and the chassis. The rear skid plate slot holes must be elongated about 1/8" with a rat tail file to accommodate the baseplate, and the original bolts are reused to remount the rear.
No. If your vehicle has a tow hook, it must be removed before installing the baseplate. The tow hook is held on by bolts using a 17mm socket. The two short bolt/washer assemblies from the tow hook are saved and reused as part of the baseplate mounting. The tow hook long bolts will not be reused.
You will need the following sockets: 3/4", 12mm, 13mm, 14mm, 17mm, and 19mm. You will also need a Phillips screwdriver and Loctite Blue. A rat tail file is required if your vehicle has a skid plate, to elongate the rear skid plate slot holes by approximately 1/8".
The hardware kit includes: 4 spacer washers (102-2962), 4 12mm-1.25 x 40mm hex bolts grade 8.8 (201-0411), 2 8mm-1.25 x 40mm hex bolts grade 8.8 (201-0418), 2 10mm-1.25 x 35mm hex bolts grade 8.8 (201-0423), 2 8mm lock washers (203-0102), 2 10mm lock washers (203-0104), 4 12mm lock washers (203-0105), 2 baseplate safety cables 36" CL IV (226-0049), and 4 quicklinks 1/2" ZP (229-0512). The two original tie down bracket bolts are also reused.
You must remove: (1) the front turn signal lenses from the bumper using a Phillips screwdriver, (2) the front bumper assembly using a 14mm socket (4 bolts total, 2 on each side), (3) the skid plate if equipped using a 12mm socket (4 bolts, 2 front and 2 rear), and (4) the tie down bracket(s) and tow hook if equipped using a 17mm socket. Save all bolts and fasteners except the tow hook long bolts, which will not be reused.
Use a Phillips head screwdriver to remove the turn signal lenses from the bumper. Note that the rubber seal is loose. Slide the turn signal assembly out toward the back of the bumper and let it hang loose. Save the screws for reinstallation.
The front bumper assembly is held on by a total of 4 bolts, 2 on each side. They are parallel to the ground and perpendicular to the center of the vehicle. Use a 14mm socket to remove them. The lower sheet metal valence will come off with the bumper. Save the bolts for reinstallation.
The baseplate mounts to the front underside of the vehicle using eight bolts total; four on each side. Four of these bolts go into threaded holes on the front chassis cross member, and four go into the holes that originally mounted the tie down bracket and tow hook.
The baseplate has four different bolt hole sizes: the two underside holes are 12mm x 1.25, the two front inside holes are 12mm x 1.25, and the two front outside holes are 10mm x 1.25. The four threaded holes on the front chassis cross member are also 12mm x 1.25.
Yes. Spacer washers must be used on the front facing side of the baseplate, between the baseplate and the chassis cross member. Four spacer washers (part 102-2962) are included in the hardware kit.
Hand start all 8 bolts with a lockwasher on each. Then tighten all bolts a little at a time, in rotation, to assure a firm, true fit. This prevents uneven seating and ensures proper alignment.
Yes. The two original short bolt/washer assemblies from the tie down bracket are saved and reused as part of the baseplate mounting. The tow hook long bolts will not be reused.
Drilling is not normally required. The baseplate is designed to use existing threaded holes on the front chassis cross member and the holes that originally mounted the tie down bracket and tow hook. However, due to dimensional variations between vehicles, it may be necessary to file or drill a hole slightly to allow a bolt to clear. On some models, a thin sheet metal bracket may interfere slightly in vertical alignment and will need to be tapped with a hammer to flatten the flange.
Yes, if your vehicle has a skid plate. The rear skid plate slot holes must be elongated about 1/8" with a rat tail file to accommodate the baseplate. The front skid plate is remounted using 8mm bolts and lockwashers provided in the kit, going through the large holes in the baseplate to the original nuts. The rear is remounted using the original bolts.
The manual does not provide specific torque values. It instructs to tighten all bolts a little at a time, in rotation, to assure a firm, true fit. The manual also states that Loctite Blue should be used on all bolts and recommends tightening to the recommended specifications, but does not specify what those specifications are. Contact the manufacturer or refer to the General Instruction Sheet included with the baseplate for torque specifications.
Permanent baseplate safety cables are strongly recommended when towing a vehicle with a tow bar. Two 36" CL IV safety cables (226-0049) are included in the hardware kit. The cables must be connected from the baseplate to the frame rail or cross member of the vehicle's frame. However, permanent baseplate safety cables are to be used in conjunction with, and NOT a replacement for legally required safety cables attaching the towed vehicle to the towing vehicle.
The permanent baseplate safety cables must be connected from the baseplate to the frame rail or cross member of the vehicle's frame. Do not mount the permanent baseplate safety cables against wires, hoses or brake lines. The manual indicates there are recommended arrangements shown in illustrations, but specific mounting locations are not detailed in the text provided.
Before each towing trip, inspect all towing equipment for: cracked welds, missing or worn parts, and loose bolts. Ensure all bolts are tightened to the recommended specifications using Loctite Blue. It is the owner's responsibility to perform these inspections.
After installation, reinstall the bumper and turn signal lenses by reversing the removal steps. Install the tow bar and safety cables according to the instructions included in their packages.
