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 Tundra (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 6,000 lbs. GTW and 600 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 10,000 lbs. WD and 1,000 lbs. WDTW. 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 Tundra (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.

No. The Curt 13180 explicitly excludes towable bumper models. If your Tundra has a towable bumper, this hitch is not compatible.
The manual lists gross load capacity specifications for both weight-carrying and weight-distribution modes, but the specific values are not filled in on the document provided. Contact Curt Manufacturing or check the product specification sheet for exact towing and tongue weight capacities. Always verify that the hitch capacity does not exceed your vehicle manufacturer's recommended towing capacity.

The CURT 56438 is designed for trucks with T5 wiring location, which is behind the passenger side rear bumper. To confirm fitment, check your vehicle owner's manual or contact the vehicle manufacturer. The manual does not list specific vehicle makes, models or years, so you should verify compatibility with CURT or your installer before purchase.
The CURT 56438 is a custom wiring harness with a converter box that connects your truck's taillight wiring to a 4-flat trailer connector. It allows you to tow a trailer with proper lighting control. The system includes signal circuits rated at 3.0 amps per side and tail/running circuits rated at 6.0 amps total.
You will need: ratchet, cutting tool, 10mm socket, flathead screwdriver, and socket extension. These are the minimum tools required for installation.
The package includes a custom wiring harness with fuse holder, a black converter box, a 4-flat dust cover, double-sided tape for mounting the converter box, and cable ties for securing wires. The manual does not specify whether the 4-flat connector itself is included or must be purchased separately.
Yes. You must disconnect the negative battery terminal before beginning installation. Keep the negative cable fastened down and away from the battery during the installation process. Reconnect it only after all other steps are complete and the fuse is installed.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating. The fuse holder is included with the harness, but the fuse itself is not installed until after the harness installation is complete.
Mount the black converter box in a flat, protected location inside the vehicle near the taillight using the provided double-sided tape. The manual emphasizes that failure to mount the box in a protected area can cause loss of warranty, product failure, overheating and potential fire. Choose a location that is sheltered from moisture, heat sources and physical damage.
1. Locate the gray plastic connector between the battery and driver-side fender and remove the protective cover. 2. Insert the custom wiring harness (with fuse holder) onto the vehicle harness, ensuring connectors are fully inserted with locking tabs in place. 3. Attach the ring terminal end to the positive battery terminal. Do not install the fuse until the harness installation is complete.
1. Locate the vehicle taillight wiring harness connectors behind the rear bumper along the passenger side frame rail. 2. Remove the protective cover, taking care not to damage the locking tabs. 3. Insert the custom wiring harness connector into the vehicle connector, ensuring it is fully inserted with locking tabs in place.
Route the 4-flat connector to the center of the vehicle close to the receiver hitch and secure it with the provided cable ties. This routing protects the connector and keeps it accessible for trailer hookup.
Secure any loose wires using the provided cable ties. This prevents wires from moving, chafing, or becoming damaged during vehicle operation.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. The manual does not specify the product's maximum rating in amps or weight. Check your vehicle owner's manual or contact CURT for the specific product rating and your vehicle's lamp load capacity.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
After installation is complete, test for proper function by using a test light or connecting a properly wired trailer. This confirms that all connections are secure and the wiring harness is functioning correctly before towing.
Yes. Install the provided 4-flat dust cover after installation is complete. This helps prevent corrosion of the connector when it is not in use.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. The manual does not specify an exact interval, but regular checks before towing are recommended to maintain warranty coverage and safe operation.
