Can I add a hitch to my Toyota Highlander?

Yes — you can add a hitch to most Toyota Highlander models, either through a factory towing package or an aftermarket hitch. The usable towing capacity depends on the engine and configuration, typically up to 5,000 pounds on non-hybrid V6 versions and about 3,500 pounds on hybrid versions.

Compatibility and Hitch Options

Several proven paths exist to equip your Highlander with a hitch, ranging from factory solutions to aftermarket choices. Each option has implications for towing capacity, warranty, and wiring integration.

• OEM towing package: Toyota’s official kit that typically includes a hitch, trailer wiring harness, and towing-related hardware. This option is designed for seamless integration with your vehicle’s electronics and often aligns with warranty expectations.


• Aftermarket Class III hitch (2-inch receiver): A widely available alternative from brands like Draw-Tite, Curt, and others. These are generally easy to install and compatible with most Highlander trims, but verify fitment for your year/model.


• Wiring harness options: 4-pin harness for basic trailer lights; 7-pin harness if you need trailer brakes or additional circuits. Some kits include a connector that plugs into the factory wiring under the rear of the vehicle.


• Brake controller considerations: If you tow trailers with electric brakes, you may need to install a separate brake controller (either aftermarket or dealer-installed) to manage braking force properly.

Choosing the right option affects towing capability, electrical compatibility, and warranty considerations. Always verify fitment for your exact year and trim with Toyota or a trusted installer.

Towing Capacity, Safety, and Legal Considerations

Understanding the numbers and rules helps ensure safe and legal towing with your Highlander. Capacity varies by powertrain and equipment, and local regulations may affect requirements for brakes and lighting on larger trailers.

• Engine and trim impact: Non-hybrid V6 Highlanders with the factory towing package can typically tow up to 5,000 pounds; Hybrid versions are usually limited to around 3,500 pounds.


• Tongue weight guideline: A practical target is about 10–15% of the trailer’s gross weight as tongue weight (for example, roughly 500–750 pounds for a 5,000-pound trailer).


• Trailer brakes and wiring: Trailers above certain weights often require electric brakes and a corresponding wiring setup (4-pin is common for basic lighting; 7-pin adds brake and auxiliary circuits). Check local laws as some states require brakes for trailers above specific weights.


• Vehicle limits and safety: Do not exceed the vehicle’s GVWR or payload, and ensure proper weight distribution, proper hitch class, and secure cargo.

Always confirm the exact towing limits for your specific Highlander by consulting the owner’s manual, the window sticker, or Toyota’s official specifications for your year and trim.

Installation Paths and Steps

There are two broad paths to get a hitch on your Highlander: using an OEM towing package or installing an aftermarket hitch. Each path has its own set of steps and considerations, including warranty implications and wiring complexity.

OEM towing package vs aftermarket

OEM towing packages are designed for plug-and-play compatibility with your Highlander’s electrical system and are generally preferred for warranty consistency and a clean factory fit. Aftermarket hitches offer a wider selection of prices and styles, but compatibility with your vehicle’s wiring and emissions controls should be verified, and some dealers may have privacy concerns if it’s not installed by a certified technician.

DIY vs professional installation

Basic aftermarket hitches can sometimes be installed by confident DIY enthusiasts, following the provided instructions. However, many Highlanders benefit from professional installation to ensure correct torque on mounting bolts, proper wiring connections, and, if required, brake controller wiring. A pro installation can also help preserve warranty coverage and provide you with a tested wiring setup.

Installation steps (typical for both OEM and aftermarket) give you a sense of the process. Use these as a guide and always follow the specific instructions for your kit and vehicle.

1. Choose the appropriate hitch kit for your Highlander’s year, trim, and towing needs (OEM or aftermarket, 2-inch Class III is common).


2. Disconnect the negative battery terminal if wiring work is involved to prevent shorts during installation.


3. Raise the vehicle safely and gain access to the frame crossmember where the hitch will mount.


4. Attach the hitch to the frame with the supplied hardware, ensuring proper alignment and torque per the kit’s specifications.


5. Install the wiring harness according to the kit’s instructions; connect to taillights and test the circuit with a trailer-light tester. If required, install a brake controller.


6. Recheck all fasteners, wiring, and clearance to exhaust components and the spare tire area; reinstall any removed panels.


7. Test drive at low speed to verify hitch engagement, lighting, and braking functionality before connecting a trailer.

With proper installation and testing, your Highlander will be equipped for towing while maintaining appropriate safety margins and functionality.

Warranty, Costs, and Where to Buy

Budgeting for a hitch involves parts, wiring, and potential installation charges. Prices vary by OEM vs aftermarket and by installer, but here is a general guide to help you plan.

• OEM towing package (parts) typically ranges from roughly $400 to $900, with dealer installation possibly adding more depending on labor rates and regional differences.


• Aftermarket Class III hitch (2") kits commonly cost between $100 and $350, plus wiring harnesses that may range from $50 to $150. Installation by a shop can run from $100 to $300, depending on local labor rates and vehicle access.


• Brake controller option (if needed): Basic units may cost around $50 to $150 for the part, with professional installation adding roughly $100 to $200 more.

Prices vary by retailer, model year, and whether you already have a compatible wiring harness. Always confirm fit and warranty coverage with the seller or installer before purchase.

Summary

Adding a hitch to a Toyota Highlander is a common and achievable upgrade. Whether you opt for Toyota’s OEM towing package or an aftermarket Class III hitch, the key details are to match the hitch to your Highlander’s engine and towing capacity, install the wiring correctly, and, if needed, add a brake controller for heavier trailers. Verify your exact towing limits in the owner’s manual or official specifications for your year and trim, and consider professional installation to ensure safety, reliability, and warranty compliance. With the right setup, your Highlander can safely tow trailers, boats, campers, or other loads within its rated capacity.

How much does it cost to add a hitch?

The cost of your trailer hitch will vary depending on your vehicle make and model, and the hitch package itself. Generally, a trailer hitch will cost anywhere from about $150 to $300. This does not include installation. When you buy from U-Haul, this cost can include a lifetime warranty for your towing equipment.
