Experience the power of Blue Ox BX4375 Tow Bar, a product born from our over 50 years of expertise in manufacturing and distributing top-tier towing products. This tow bar, belonging to our renowned Blue Ox line, holds a reputation for setting the industry standard in vehicle towing. With its robust construction finished in a durable powder coat, it promises to withstand tough conditions while delivering exceptional performance. The BX4375 is compatible with a wide array of applications, extending its offering to include vehicle braking systems, steering products, weight distribution, and gooseneck hitches. It's not just a tow bar - it's a powerful tool designed to enhance your vehicle's capabilities.
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 BX4375 is a Class III tow bar rated for 7,500 lb towing capacity. However, the actual towing capacity of your system is limited by the lesser of the tow bar capacity and the hitch connector capacity. You must also verify that your towing vehicle's weight and braking capacity are adequate to handle both vehicles in an emergency situation, and check your towing vehicle manufacturer's recommendations for towing, hitch load, and braking capacities.
Yes. The BX4375 Ascent Tow Bar is designed for 2-1/2 inch receivers. The standard hitch connector for 2-1/2 inch receivers is the BX88425. Optional hitch connectors for 2-1/2 inch receivers include BX88424, BX88426, BX88434, and BX88395.
The BX4375 is designed for 2-1/2 inch receivers. If you have a 2 inch receiver, you would need a different hitch connector. Blue Ox offers optional hitch connectors for 2 inch receivers: BX88433 and BX88395. Contact your Blue Ox dealer to confirm compatibility with your specific setup.
The BX4375 includes the tow bar assembly with two legs, a hitch connector (BX88425 for 2-1/2 inch receivers), a receiver pin, two 1/2 inch pins, two quick pins, and two triple lugs with attachment hardware. The manual does not specify whether a baseplate for the towed vehicle is included; you should verify this with your dealer or check your order documentation.
Yes. Blue Ox strongly recommends registering your product online at www.blueox.com. Registration is crucial so you can be alerted of product offerings, updates, upgrades, maintenance and safety bulletins, and recalls. Additionally, warranty coverage requires that the customer warranty card be returned within 30 days of purchase.
Slide the hitch connector into the receiver tube of your towing vehicle hitch, ensuring the tow bar is right side up with the locking handles on top. Install the receiver pin provided into one of the two holes of the hitch receiver; the inside hole is most commonly used. The configuration of your towing vehicle's rear will determine how far you can slide the hitch connector into the receiver tube. When the tow bar is folded, you may need to change which set of holes are used in the hitch connector or order a longer hitch connector.
Partially extend one leg by pulling out on it to disengage the internal soft latch. Place the triple lug between the attachment tabs on the baseplate and secure with the 1/2 inch pin and quick pin. Ensure the 1/2 inch pin is installed correctly through the attachment tab with the nose towards the middle of the baseplate. Repeat for both legs. Then pull forward with the towing vehicle until one or both locking handles engage and lock (they will pop up when locked).
If only one locking handle is locked, turn the towed vehicle's steering wheel towards the unlocked tow bar leg approximately 1/2 to 3/4 turn before continuing forward. Drive the towing vehicle forward until the second leg locks into place.
The attachment points at the center of the attachment tabs and the center of the towed vehicle's hitch receiver should be of equal distance. If a deviation must occur, the hitch receiver should be no more than 3 inches above or below the attachment tabs of the baseplate.
Blue Ox approves a maximum of two connection points between the towing and towed vehicle, with a length no greater than 13.5 inches (hitch pin to hitch pin) on the extension/drop receiver. For example, having a tow bar, drop receiver, and hitch extender together is not recommended as it exceeds the maximum two points of connection. Using extensions that exceed these specifications voids all warranties and constitutes dangerous misuse of the product.
Attach the safety cables to a solid part of the chassis on the towed vehicle or the convenience links of the baseplate in a crossing pattern underneath the tow bar. Verify the safety snap clicks back against the hook to prevent disconnection. Adjust slack to allow enough room for turns. Cables must not contact the ground, pintle coupler, or locking handles, as damage could occur. Route cables away from the locking handles. Do not wrap safety cables around the legs, as contact with a locking handle could cause the leg to become unlatched and collapse.
Park the towing vehicle with vehicle in tow in a straight line on a level surface and engage the parking brake. Place the towed vehicle in park (automatic) or first gear (manual) and engage its parking brake. Unhook the lighting and safety cables. Disengage the leg latches by pushing down on the locking handles. Remove the quick pins and 1/2 inch pins attaching the triple lugs to the attachment tabs; you may need to tap the 1/2 inch pins out if there is still pressure on them. Compress both legs completely until they lock in place. Place the 1/2 inch pins back into the triple lugs and secure with the quick pins to avoid losing them.
To store the tow bar: 1) Swing the legs inwards towards each other. 2) With legs together, swing them up towards the towing vehicle. 3) Rotate the legs down to either side until the ears of the leg capture the hold up tab of the hitch connector. Keep the tow bar covered when not in use, on or off the towing vehicle, to reduce dirt buildup.
Before each trip, check for movement in the baseplate by grabbing the baseplate tabs and moving up and down to ensure it is still secure to the vehicle's frame. Prior to usage, inspect all towing equipment for cracked welds, missing or worn parts, and loose bolts. Verify that both legs are latched properly and pins are secured properly; the quick pin ring should snap back onto itself with the chamfered side facing outwards. Ensure the steering wheel on the towed vehicle is unlocked. Check clearance between vehicles in all turning situations and verify the height difference in your towing setup.
Yes. The steering wheel on the towed vehicle must be unlocked at all times while being towed. Failure to do so will create hazardous driving conditions.
No. Do not back up while vehicles are connected. Disconnect the towed vehicle from the towing vehicle before backing up. Backing up while connected can cause damage to both vehicles and the towing system. The towed vehicle may jackknife, causing abnormal stress to the tow bar, car chassis, baseplate, and pintle hitch of the towing vehicle. These abnormal stresses may cause damage that may go undetected.
If the tow bar 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 tow bar if it is damaged or missing parts.
Yes. The use of safety cables or chains is required by law in most states of the United States as well as Canadian territories and provinces. Follow state or territory recommendations. Blue Ox strongly recommends the use of safety cables (BX88196 for Class III or BX88197 for Class IV) and permanent safety cables (BX88207 for Class III or BX88208 for Class IV) with all applications of towing. Refer to their specific installation instructions for more information.
Rear lighting is required on the towed vehicle. Blue Ox offers lighting kits to cover all of your lighting needs. Contact your Blue Ox representative for more information.
Blue Ox recommends a full tow bar service every two years or 10,000 miles, whichever comes first. Before each trip, check for movement in the baseplate. Periodically clean the entire surface of the tow bar with a mild soap and water solution and wipe dry. Check for cracked welds and repair any loose, worn, or damaged bolts, rubber boots, or cap plugs. Approximately once per year or if it is difficult to move the legs in and out, remove the cable ties holding the rubber boots to the legs, clean the inner legs with silicone spray or brake cleaner, and apply a light coat of multipurpose grease to each leg.
Approximately once per year or if it is difficult to move the legs in and out, remove the small cable ties holding the rubber boots to the legs and slide the boots back. Clean off the inner legs with a silicone spray or brake cleaner. Apply a light coat of multipurpose grease to each leg to ensure smooth operation. Secure each boot back in place with an 8 inch UV rated nylon cable tie. Only the inner legs require grease for normal operation. All other tow bar joints rely on self-lubricating washers; if these joints become too stiff, clean with soap and water.
If the tow bar's legs do not operate smoothly or the joints become excessively loose, take your tow bar to an authorized Blue Ox dealer or call Blue Ox Customer Care at 402-385-3051 for repairs. You can also have your tow bar serviced for a fee by a Blue Ox technician at rallies, by visiting the Pender facility, or by mailing your tow bar to the factory.
Blue Ox recommends the BX88309 tow bar cover. Keeping the tow bar covered when not in use, on or off the towing vehicle, will cut down on dirt buildup on the legs and joints of the tow bar.
Replacement parts include: leg assemblies (driver side 84-0213, passenger side 84-0214), hitch connectors (BX88425 standard for 2-1/2 inch), triple lug kit (BX88154), pins and quick pins, rubber boot kit (84-0229), latch assembly kits (84-0191 driver side, 84-0195 passenger side), latch retainer kit (84-0221), handle grip kit (84-0194), washer replacement kit (84-0196), and pivot shaft bushing kit (84-0204). Use only genuine factory replacement parts. If a bolt is lost or needs replacement, use a replacement bolt of the same grade (typically Grade 5). Order parts through your nearest Blue Ox dealer or distributor.
No. Use only genuine factory replacement parts on your tow bar. Do not substitute homemade or non-typical parts. If a bolt is lost or in need of replacement, for your safety and the preservation of your tow bar, be sure to use a replacement bolt of the same grade (in most cases it will be Grade 5). Failing to follow and/or altering these installation instructions in either installation or required equipment will void the manufacturer's warranty.

Yes, the BX4375 is designed for 2-1/2 inch receivers. The standard hitch connector is BX88425. Optional connectors BX88424, BX88426, BX88434, and BX88395 are also available for 2-1/2 inch receivers.
The BX4375 is a Class III tow bar rated for 7,500 lb. The actual towing capacity is limited by the lesser of the tow bar and hitch connector capacities. Verify your towing vehicle can handle both vehicles in an emergency.
No. Disconnect the towed vehicle before backing up. Backing up while connected can cause damage to both vehicles and the towing system, and may cause the towed vehicle to jackknife.
Yes. Safety cables or chains are required by law in most US states and Canadian territories/provinces. Blue Ox recommends Class III cables BX88196 or permanent cables BX88207.
If the BX4375 is in an accident or damaged, it must be replaced and not used again. Unseen damage could cause more damage or serious injury.
If there is still pressure on the 1/2 inch pins, they may be difficult to remove. Park the towing vehicle with vehicle in tow in a straight line on a level surface to ensure minimum pressure is exerted on the tow bar legs. This will aid in the removal of the 1/2 inch pins. You may need to tap the pins out if pressure remains.
If only one locking handle is locked, turn the towed vehicle's steering wheel towards the unlocked tow bar leg approximately 1/2 to 3/4 turn before continuing forward. Drive the towing vehicle forward until the second leg locks into place.
Misaligned towed vehicles may cause poor tracking or abnormal wear on the tires. Ensure the front end of the towed vehicle is properly aligned before towing.
Safety cable contact with a locking handle could cause the leg to become unlatched and collapse, leading to major damage to one or both vehicles and towing equipment. Route safety cables away from the locking handles and do not wrap safety cables around the legs. Ensure cables do not contact the ground, pintle coupler, or locking handles.
