1. Blue Ox BX88144 Tow Bar: Top Pick
The Blue Ox BX88144 is a premium tow bar that we evaluated as the best overall for semi truck towing. Based on owner feedback and the spec sheets, its 10,000 lb capacity and non-binding folding design make it a favorite among recovery professionals. The arms lock securely in the deployed position and fold flat for storage without needing to remove them from the hitch. Safety cables and a robust clevis pin system add to its reliability.
However, this tow bar is on the heavier side, which may be a drawback for those who frequently mount and dismount it alone. If you prioritize lightweight portability over ruggedness, consider a lighter aluminum model. But for most semi truck towing needs, the Blue Ox delivers unmatched durability and ease of use.
- Non-binding folding arms for compact storage and easy deployment
- Rated for 10,000 lbs gross towing weight, suitable for most semi trucks
- Includes safety cables and 2 inch hitch receiver compatibility
Pros: Excellent build quality with powder-coated finish resists rust; Arms fold easily without tools, saving time on the roadside
Cons: Heavier than some competitors at around 70 pounds
2. Roadmaster 5250 Tow Bar: Best Value
The Roadmaster 5250 offers a compelling combination of capacity and adjustability at a value that stood out in our comparison. Based on owner feedback and the spec sheets, the adjustable arm length (58 to 66 inches) allows it to fit a wide range of semi trucks, from day cabs to sleeper cabs. The non-binding pivot design ensures smooth operation even when turning at sharp angles. Safety cables and a solid clevis pin system are included.
One limitation noted in our evaluation is that the powder coat finish is less durable than some premium competitors, and owners in salt-belt states reported minor chipping after a few seasons. If you operate in corrosive environments, you may prefer a stainless steel or galvanized option. Otherwise, this is a reliable and affordable choice for most semi truck towing tasks.
- Adjustable arm length from 58 to 66 inches for versatile fitment
- Rated for 10,000 lbs with a 2 inch hitch receiver
- Includes safety cables and a non-binding pivot design
Pros: Adjustable arms accommodate different truck frame widths; Strong steel construction at a competitive price point
Cons: Finish may chip over time in harsh environments
3. CURT 17500 Tow Bar: Heavy Duty
The CURT 17500 is built for the heaviest towing jobs. In our evaluation, its 12,000 lb capacity and forged steel construction make it a top choice for recovering fully loaded semi trucks or heavy equipment. Based on owner feedback and the spec sheets, the solid steel pivot pins and reinforced arms provide confidence even under extreme loads. The folding design helps with storage, though it remains large.
The main drawback is its weight and size. At over 80 pounds, it can be cumbersome to handle alone, and it requires a sturdy hitch mount. If you occasionally tow lighter trucks, a 10,000 lb model may be more practical. But for serious heavy-duty use, the CURT 17500 is a workhorse that delivers.
- 12,000 lb capacity for heavier semi trucks and loaded trailers
- Forged steel arms and solid steel pivot pins for maximum strength
- Folds for storage and includes safety cables
Pros: Highest capacity in our lineup, suitable for heavy recovery; Forged steel components offer exceptional durability
Cons: Heavier and bulkier than most, weighing over 80 pounds
4. Demco 8700 Tow Bar: Easiest Setup
The Demco 8700 is designed for speed and convenience. In our comparison, its quick-connect system allows you to attach the tow bar to pre-installed brackets on the towed vehicle in seconds, without tools. Based on owner feedback and the spec sheets, this is a favorite for fleet operations where time is critical. The lightweight construction (45 pounds) makes it easy to handle.
However, the 8,000 lb capacity limits its use to lighter semi trucks or those that are not fully loaded. If you regularly tow heavy sleeper cabs or loaded trailers, this model may not be adequate. Also, the aluminum-steel hybrid is less durable than all-steel designs under heavy repeated use. But for quick, light-duty towing, it is excellent.
- Quick-connect clevis system for fast attachment to truck frame brackets
- 8,000 lb capacity suitable for lighter semi trucks and bobtails
- Lightweight aluminum-steel hybrid at 45 pounds
Pros: Very easy to attach and detach, even by one person; Lightweight design reduces fatigue during setup
Cons: Lower capacity may not suit heavy or loaded trucks
5. Tow Ready 64490 Tow Bar: Budget Friendly
The Tow Ready 64490 is a no-frills option for those on a tight budget. In our evaluation, it provides adequate capacity for occasional towing of lighter semi trucks, such as bobtails or empty day cabs. Based on owner feedback and the spec sheets, the folding arms and included safety cables are standard, and the price is hard to beat.
However, durability concerns surfaced in our research. Some owners reported minor weld defects or premature rust on the powder coat. We recommend inspecting the welds upon arrival. If you need a tow bar for frequent heavy use, investing in a higher-end model is wise. But for occasional light-duty towing, this is a functional budget pick.
- 8,000 lb capacity for occasional towing of smaller semi trucks
- Folding arms for compact storage
- Includes safety cables and a 2 inch hitch shank
Pros: Very affordable for the capacity offered; Folding design saves space when not in use
Cons: Some owners report weld quality inconsistencies
6. Blue Ox BX8830 Tow Bar: Compact Design
The Blue Ox BX8830 is a specialty tow bar for very light towing. In our evaluation, its 6,000 lb capacity and 48 inch arms limit it to towing small trucks or equipment, not full-size semi trucks. Based on owner feedback and the spec sheets, the compact folding design is excellent for storage in a pickup truck or service vehicle. It is well-built with Blue Ox’s typical quality.
However, most semi truck operators will find the capacity insufficient. If you only need to tow a small bobtail or a light-duty truck, this could work, but for standard semi truck recovery, we recommend a higher-capacity model. Skip this if you need to tow anything heavier than a medium-duty truck.
- 6,000 lb capacity for lighter towing needs
- Short 48 inch arms for tight spaces and easy storage
- Folds to a very compact size, fits in small truck beds
Pros: Extremely compact when folded, ideal for limited storage; Blue Ox quality with a powder-coated finish
Cons: Low capacity not suitable for most semi trucks
7. Roadmaster 5200 Tow Bar: Versatile
The Roadmaster 5200 is a lighter-duty version of the 5250. In our evaluation, its 6,000 lb capacity and adjustable arms make it suitable for towing smaller trucks or equipment. Based on owner feedback and the spec sheets, it offers decent versatility for the price, with folding arms and safety cables included. The adjustable length is a plus for odd frame widths.
However, the capacity is too low for most semi trucks, and the build quality is not as robust as the heavier Roadmaster models. Owners reported that the finish can wear quickly. If you need a tow bar for occasional light towing, it may suffice, but we recommend stepping up to the 5250 for semi truck use. Skip this if you plan to tow anything over 6,000 lbs.
- 6,000 lb capacity for light-duty towing
- Adjustable arms from 52 to 60 inches for fitment flexibility
- Folding design with included safety cables
Pros: Adjustable length helps fit various truck frames; Reasonable price for a versatile tow bar
Cons: Lower capacity and durability than heavier-duty models
Frequently Asked Questions
What is the towing capacity needed for a semi truck?
The towing capacity you need depends on the weight of the semi truck you are towing. A typical unladen semi truck (tractor only) weighs around 17,000 to 20,000 pounds, but tow bars are rated for the gross towing weight, which includes the tow bar itself and any accessories. Most heavy-duty tow bars are rated at 10,000 lbs or 12,000 lbs, which is sufficient for towing a disabled semi truck that is not fully loaded. Always check your vehicle’s weight and the tow bar’s rated capacity before use.
Can I use a tow bar for a semi truck with a standard hitch receiver?
Yes, most tow bars for semi trucks are designed to fit a standard 2 inch hitch receiver, which is common on heavy-duty pickup trucks and recovery vehicles. However, some heavy-duty tow bars may require a 2.5 inch receiver for higher capacities. Always verify the hitch receiver size on your tow vehicle and match it to the tow bar’s shank size. Using an adapter may reduce capacity.
How do I attach a tow bar to a semi truck?
Attaching a tow bar typically involves mounting base plates or brackets to the frame of the disabled semi truck (permanent installation) or using a clevis pin system that connects to existing frame holes. Many tow bars come with a clevis pin and clip that attach to brackets on the towed vehicle. The other end connects to the tow vehicle’s hitch receiver. Always follow the manufacturer’s instructions and use safety cables as a backup.
Are tow bars safe for towing a semi truck on highways?
Yes, when used correctly and within their rated capacity, tow bars are safe for highway towing. It is essential to use safety cables, ensure proper attachment, and follow all local regulations. The tow bar should be rated for the weight of the towed vehicle, and the tow vehicle must have adequate braking and lighting systems. Regular inspection of the tow bar for wear and damage is recommended.
Do I need a special tow bar for a semi truck with air brakes?
No, a special tow bar is not required for air brake systems. However, you must ensure that the disabled truck’s air brake system is properly released or caged before towing. Some tow bars include provisions for connecting air lines, but most standard tow bars do not. You may need additional equipment, such as a supplemental braking system or air line kits, to comply with safety regulations.
