How Much to Put a Tow Bar on a Car: Cost Guide

Installing a tow bar on your vehicle can significantly expand its utility, allowing you to haul trailers, carry bike racks, or even tow a small caravan. However, before you embark on this automotive upgrade, a crucial question often arises: how much to put a tow bar on a car? The cost isn’t a single, fixed figure; rather, it’s a dynamic range influenced by various factors, including the type of tow bar, your car’s make and model, and whether you opt for professional installation or a DIY approach. Understanding these elements is key to budgeting effectively for this valuable addition to your vehicle.

Understanding Tow Bars: Types and Components

Before delving into costs, it’s important to understand what a tow bar entails. A tow bar, also known as a tow hitch or trailer hitch, is a device attached to the chassis of a vehicle for towing a trailer, caravan, or other loads. It comprises mechanical components for coupling and often electrical connections for trailer lights and brakes.

Different Types of Tow Bars

The market offers several types of tow bars, each with its own design, functionality, and cost implications:

• Fixed Flange Tow Bar: This is often the most traditional and robust type. It features a tow ball bolted to a faceplate, allowing for various accessories to be attached alongside the ball, such as bumper protectors or cycle carriers. These are generally the most affordable and visible.
• Fixed Swan Neck Tow Bar: Similar to the flange type in its fixed nature, the swan neck features a sleeker, integrated design where the tow ball and neck are a single unit. This often looks more aesthetically pleasing but limits the ability to attach additional accessories directly to the tow bar itself.
• Detachable Swan Neck Tow Bar: This type offers the convenience of removing the tow ball assembly when not in use, preserving the car’s aesthetic and preventing shin-bumping. They typically use a quick-release mechanism. Detachable options are often more expensive due to their complex locking and unlocking mechanisms.
• Retractable Tow Bar: The most advanced and discreet option, a retractable tow bar can be electronically or manually folded away behind the bumper when not needed, becoming virtually invisible. This premium feature comes with the highest price tag.
• Specific Vehicle Tow Bars: Some vehicles, particularly SUVs or trucks designed for heavy towing, might have integrated or specially designed tow bar systems that differ from generic aftermarket options.

Essential Components Beyond the Bar

Beyond the physical bar, a complete tow bar system requires electrical connections. These typically include:

• Wiring Harness: Connects the car’s electrical system to the trailer’s lights (brake, indicators, tail lights).
• 7-Pin Electrics: Standard for basic lighting functions on older or simpler trailers.
• 13-Pin Electrics: Increasingly common, especially on newer vehicles and for caravans, offering additional functions like reverse lights, charging for leisure batteries, and powering interior appliances.
• Vehicle-Specific Wiring Kits: These integrate seamlessly with the car’s existing electronics, often preventing fault codes and ensuring compatibility with safety features like trailer stability assist. They are generally more expensive but highly recommended for modern cars.
• Universal Wiring Kits: Less expensive but may require cutting and splicing wires, which can sometimes lead to electrical issues or bypass vehicle safety systems.

Understanding these types and components helps clarify why the cost to put a tow bar on a car can vary so widely. Each choice impacts material costs, installation complexity, and ultimately, the final price.

Legal Considerations for Tow Bar Usage

Beyond knowing how much to put a tow bar on a car and ensuring its proper installation, it’s crucial to be aware of the legal aspects associated with towing to avoid penalties and ensure compliance. Regulations can vary significantly by state or country, so it’s always best to check local laws.

Maximum Towing Capacity

Every vehicle has a maximum towing capacity, specified by the manufacturer. This limit often differentiates between “braked” and “unbraked” trailers. It is illegal and extremely dangerous to exceed your vehicle’s stated towing capacity. This information can usually be found in your car’s owner’s manual or on a plate affixed to the vehicle.

Tow Bar Type Approval

In many regions, tow bars must be “Type Approved” (e.g., E-marked in Europe) to be legally fitted and used. This certification ensures the tow bar meets specific safety and manufacturing standards. Reputable installers will only fit type-approved tow bars.

Trailer Lighting and Electrics

• Mandatory Lights: All trailers must have working tail lights, brake lights, and indicator lights that mirror the towing vehicle. Reflectors are also typically required.
• Number Plate Illumination: The trailer’s number plate must be clearly visible and adequately illuminated at night.
• 13-Pin vs. 7-Pin: Depending on the trailer’s size, age, and functions, the type of electrical connection required may vary. For instance, caravans often require 13-pin electrics for reverse lights, internal power, and charging.

Number Plate Visibility

When a trailer is attached, the towing vehicle’s number plate must not be obscured. If it is, or if you are using a bike rack that covers the plate, you are legally required to display a separate, illuminated number plate on the trailer or accessory. This plate must match the vehicle’s registration.

Extension Mirrors

If the trailer or caravan you are towing is wider than your vehicle, you are generally legally required to use extension mirrors to ensure you have a clear view down both sides of the trailer. Failing to have adequate rearward vision can result in fines.

Speed Limits

Many jurisdictions impose lower speed limits for vehicles towing a trailer compared to standard passenger vehicles. Always be aware of and adhere to these reduced limits.

Vehicle Insurance

Inform your insurance provider that you have installed a tow bar and intend to tow. While often covered, it’s essential to confirm that your policy covers towing and any potential damage to the tow bar, trailer, or third parties while towing.

Driving License Requirements

For heavier trailers or certain combinations of vehicle and trailer weight, you might require a specific category of driving license (e.g., a “B+E” category in some European countries). Ensure your license permits you to tow the weight you intend to.

Ignoring these legal considerations can lead to fines, points on your license, insurance complications, and, most importantly, serious safety risks. A proper understanding and adherence to towing laws are as crucial as the installation itself when considering how much to put a tow bar on a car and use it effectively.

Installing a tow bar on your car is a practical investment that significantly enhances your vehicle’s capabilities. The total cost to put a tow bar on a car is primarily influenced by the type of tow bar you choose, the complexity of your vehicle’s electrical system, and whether you opt for professional installation or a DIY approach. While basic setups can be relatively inexpensive, more advanced systems for modern vehicles often require specialized wiring and coding, pushing the cost into a higher bracket. Regardless of the specifics, prioritizing a safe and correctly installed system ensures reliable performance and allows you to fully enjoy the versatility your new tow bar offers.
