Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Toyota Grand Highlander, Lexus TX 350, TX 500h, and TX 500h+ (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 500 lbs. TW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Toyota 4Runner, Toyota Highlander, Toyota Grand Highlander, Toyota Land Cruiser, Lexus LX470, Lexus LX570, Lexus RX300, Lexus TX350, Lexus TX500h, and Lexus TX550h+ (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The complete kit includes everything you need: the Class 3 hitch rated for 5,000 lbs GTW and 500 lbs TW, plus the 5-flat wiring setup with the boat trailer surge brake adapter.

Absolutely! This CURT kit is engineered specifically for 2024-2025 Toyota Grand Highlander models. The hitch provides a custom vehicle-specific fit with concealed mounting for an OE look, while the wiring system is designed to integrate seamlessly with your Grand Highlander's electrical system.
This custom kit fits 2024-2025 Toyota Grand Highlander models exclusively. The hitch portion also works on Lexus TX 350, TX 500h, and TX 500h+ from the same years, but this particular bundle is optimized specifically for the Grand Highlander application. Always double-check your exact year and model to ensure proper fitment.
The installation is designed to be straightforward with the vehicle-specific design and plug-and-play wiring system. The wiring connector plugs directly into your Grand Highlander's existing OEM socket (factory tow package required), eliminating any cutting or splicing. Both the hitch and wiring come with complete installation instructions and all necessary mounting hardware, so you can tackle it with basic hand tools.
Curt part 55245 is designed for Lexus LX 470, Lexus RX 300, Toyota 4Runner, Toyota Highlander, and Toyota Landcruiser. Verify your vehicle model matches this list before purchasing.
The manual does not specify what components are included in the kit. Contact Curt Manufacturing or your retailer for a complete parts list.
The factory tow plug is located behind the bumper (marked as S6). On some vehicles, the tow plug may be hidden under a black box cover secured with 10 mm hex bolts. Remove these bolts to access the plug.
You will need a 10 mm hex wrench or socket to remove the bolts securing the black box cover (if present on your vehicle). A 20 amp fuse is required for Highlander and RX300 models.
Insert the harness connector into the vehicle's factory harness connector (located at S6 behind the bumper). Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location.
A 20 amp fuse is required for Lexus RX300 and Toyota Highlander models. Locate the fuse panel on the driver's side of the engine compartment and insert the fuse in the location marked 'towing'. Other vehicles in the compatibility list may not require this step; consult your vehicle's manual if uncertain.
Before drilling, verify that no miscellaneous items (wiring, fuel lines, brake lines, etc.) are hidden behind or under any surface where you plan to drill. Drilling into hidden components can cause damage and personal injury.
Yes, if you own a Lexus LX 470, RX 300, or a Toyota 4Runner, Highlander, or Landcruiser. Other models are not compatible.
A 10 mm hex wrench to remove the black box cover (if present), and a 20 amp fuse for Highlander and RX300 models.
The manual does not specify whether professional installation is required or recommended. Contact Curt Manufacturing or a qualified installer if you are unsure about performing the installation yourself.
The 13519 has a gross trailer weight (GTW) capacity of 5,000 lbs and a tongue weight (TW) capacity of 500 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The kit includes 4 hex bolts (M12) and 4 conical-toothed washers (1/2"). These fasteners are used to secure the hitch to the vehicle frame weldnuts.
You will need: ratchet, flathead screwdriver, 19mm socket, safety glasses, and a torque wrench. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
Yes. Use a flathead screwdriver to remove the two plastic weldnut plugs on the outer side of the frame rail on both sides of the vehicle. Return the plugs to the vehicle owner after installation.
To remove debris from weldnuts in the frame, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush. Take care not to damage the threads.
1. Remove the two plastic weldnut plugs from the frame rails using a flathead screwdriver. 2. Raise the hitch into position and align the mounting holes with the weldnuts in the frame. 3. Loosely install the hex bolts and conical-toothed washers. 4. Torque all hardware to 86 ft-lbs.
Yes. Loosely install the supplied hex bolts and conical-toothed washers first to align the hitch properly with the frame weldnuts. Only after alignment is complete should you torque all hardware to the final specification of 86 ft-lbs.
All hardware on the 13519 must be torqued to 86 ft-lbs.
The hitch uses four M12 hex bolts to secure it to the vehicle frame weldnuts.
The hitch uses four 1/2" conical-toothed washers. These washers must be oriented correctly under the bolt heads to ensure proper clamping force.
The conical-toothed washers must be installed with the toothed side facing the hitch side plate. The assembly diagram on page 2 shows the correct orientation: the washer sits between the hex bolt head and the hitch mounting surface.
Safety glasses must be worn at all times while installing this product. Additionally, never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. This helps prevent damage to the product and vehicle.
