The Blue Ox BX3750 Tow Bar Bracket is a top-quality, custom-designed base plate made for your specific towing needs. Developed to excel under the most demanding conditions, it is constructed from robust steel and finished with a durable black powder coat to resist corrosion and wear. This bracket comes with all the necessary hardware and comprehensive instructions for a hassle-free, do-it-yourself installation. With its bolt-on mounting type, the Blue Ox BX3750 offers an easy and secure attachment without the need for any additional tools or adjustments.
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.

Yes, the BX3750 is designed for the 2003 Toyota Matrix. The attachment tabs are 20 inches center to center with a height of 16 inches. The manual notes that dimensional variations between otherwise identical cars can be considerable, so it may be necessary to file a hole slightly to allow a bolt to clear during installation.
The BX8869 is available for the 2003 Toyota Matrix and is shown in the manual as being located at the driver's side tail light assembly. However, the manual does not specify whether it is required or optional for the BX3750 baseplate installation. Contact your Blue Ox dealer or distributor for clarification on whether this accessory is needed for your vehicle.
Yes. The front fascia and metal bumper must be removed for baseplate installation. The removal process involves removing push pins, metric bolts, and electrical tie downs. Steps 1–5 detail the complete removal procedure, which requires a 10MM socket, 14MM socket, and Phillips screw driver.
Yes, drilling is required. You must drill a 1 1/4" hole in the frame on both sides (using a 1 1/4" drill bit or hole saw), drill out existing holes with a 17/32" drill bit on both sides, and drill remaining holes on the bottom of the frame rail using a 13/32" drill bit on both sides. You will also need to trim the lower grill as needed to align the fascia with its original position.
You need three drill bit sizes: 1 1/4" (or a 1 1/4" hole saw), 17/32", and 13/32". The 1 1/4" hole is drilled in the frame to gain access to the inside of the frame on both sides. The 17/32" holes are drilled on both sides of the frame rail, and the 13/32" holes are drilled on the bottom of the frame rail.
Required tools are: 10MM socket, 14MM socket, 3/4" socket, 9/16" socket, Phillips screw driver, 1 1/4" hole saw (or 1 1/4" drill bit), 17/32" drill bit, 13/32" drill bit, vise grips, and Loctite Red. A drill and power tools are implied but not explicitly listed.
The baseplate includes: 1 weldment base plate (61-5786), 4 nut plates with 10" wire (61-5338), 4 nut plates (61-5208), 4 hex bolts 1/2-13 x 1 1/2" Grade 5 (201-0051), 4 lock washers 1/2" (203-0012), 4 bolts 3/8-16 x 1 1/2" Grade 5 (201-0440), 4 lock washers 3/8" (203-0010), 2 self-drilling screws #12-14 x 1" (201-0979), 2 slot round head screws #10-32 x 1/2" (201-0192), 2 lock washers #10 (203-0054), 2 hex nuts #10-32 (202-0047), 2 4-way connectors (101-5822), 2 attachment assemblies L/B SF (R) (62-3469), 2 baseplate safety cables 36" Class III (226-0046), 2 quicklinks 3/8" (229-0359), and 2 receiver cap plugs black (290-0437).
The manual does not provide torque specifications. It states that bolts should be tightened to 'recommended specifications' and that Loctite Red must be used on all bolts before tightening. Contact your Blue Ox dealer or distributor for the specific torque values for the 1/2-13 and 3/8-16 bolts.
The drilling sequence is: (1) Drill a 1 1/4" hole in the frame on both sides to gain access to the inside of the frame (step 6); (2) Drill out existing holes with a 17/32" drill bit on both sides, insert the nut plate into the 1 1/4" hole to align, and tighten bolts (step 7); (3) Using the baseplate as a template, drill the other 17/32" hole on the inside of the frame rail on both sides (step 7); (4) Drill remaining holes on the bottom of the frame rail using a 13/32" drill bit on both sides (step 8).
Yes. Loctite Red must be used on all bolts before tightening. This is specified in steps 7 and 8, and reiterated in the General Information section, which states that owners should use Loctite Red on all bolts and tighten to recommended specifications before each towing trip.
Insert the nut plates (items 2 and 3) into the 1 1/4" holes to align with the drill holes before tightening the bolts. The baseplate itself is then used as a template to drill the other 17/32" hole on the inside of the frame rail on both sides. When reinstalling the fascia, hold it to align with its original position.
The manual states that dimensional variations between otherwise identical cars can be considerable. While the baseplate holes were designed for easy installation, it may be necessary to file a hole slightly to allow a bolt to clear. Do not force bolts or modify the baseplate structure.
Permanent baseplate safety cables are strongly recommended when towing a vehicle with a tow bar. They prevent the towed vehicle from breaking loose if the connection between the frame and baseplate fails. Two 36" Class III safety cables (226-0046) and two quicklinks (229-0359) are included with the BX3750. These cables must be connected from the baseplate to the frame rail or cross member and must not be mounted against wires, hoses, or brake lines. They are to be used in conjunction with, and not as a replacement for, legally required safety cables.
No. Do not mount the permanent baseplate safety cables against wires, hoses, or brake lines. Improper installation against these components could cause fluid leaks or electrical shorts some time after the baseplate installation. It is the installer's responsibility to watch for oil cooler and air conditioner lines, electrical wires and hoses, and missing parts or attaching points on the frame.
Before each towing trip, inspect all towing equipment for cracked welds, missing or worn parts, and loose bolts. Ensure that Loctite Red is used on all bolts and that they are tightened to the recommended specifications. It is the owner's responsibility to perform these inspections.
Yes. Blue Ox strongly recommends registering your product online at www.blueox.com. Registration is crucial so that you may be alerted of product offerings, updates, upgrades, maintenance and safety bulletins, and/or recalls.
Do not substitute other devices if the tow bar pin and clip are lost. Contact your Blue Ox dealer or distributor to order genuine replacement parts. Using non-genuine substitutes could compromise safety.
Remove the attachment tabs when not in use, if applicable. This helps protect the baseplate and attachment points when the vehicle is not being towed.
No. If a bolt is lost or needs replacement, use only a replacement bolt of the same grade, which is usually Grade 5. Do not substitute homemade or nontypical parts. For your safety and the preservation of your baseplate, order repair parts through your nearest Blue Ox dealer or distributor.
