All Hardware and Installation Instructions Included!
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 Subaru Ascent (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 675 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 Subaru Ascent, Forester, Outback, Crosstrek and XV Crosstrek (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 19 - 24 Subaru Ascent Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13400 (Part #5W-CHW-2734) fits the following vehicles: 2019-2024 Subaru Ascent. Always verify your specific year, make, and model before ordering.
The 19 - 24 Subaru Ascent Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13400 (Part #5W-CHW-2734) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, CURT part number 13400 is designed for 2019-Present Subaru Ascent SUVs. This is a weight-carrying hitch with a maximum trailer weight capacity of 5,000 lbs and tongue weight capacity of 675 lbs. Always verify your vehicle matches the year and model before purchasing.
The CURT 13400 is rated for a maximum trailer weight of 5,000 lbs and a tongue weight of 675 lbs when used as a weight-carrying hitch. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
Required tools are: ratchet, 10mm socket, 12mm socket, 3/4" socket, 6" extension, torque wrench, die grinder, safety glasses, and a pry bar. A tape measure and aviation shears are also listed as helpful for installation.
Yes. The first installation step requires you to lower and remove the spare tire following your vehicle owner's manual. The spare tire is reinstalled at the end of the installation after the hitch is secured.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and notes that using proper tools will greatly improve installation quality and reduce time required. If you are hesitant to undertake this task, contact an authorized CURT installer for assistance.
Yes. Installation requires trimming the heat shield to allow access to the front-center mounting holes and enlarging the forward-most mounting hole with a die grinder to allow the 1/2" carriage bolt to fit through. These are permanent modifications to the vehicle.
Fishwire is a technique to route fasteners through frame holes when direct access is limited. For the CURT 13400, you thread the 1/2" carriage bolt and spacer through the forward-most frame hole into the center and rear frame holes on both sides, then reverse fishwire the fasteners back into the forward-most hole. This allows proper alignment of the hitch to the frame.
All 1/2" hardware must be torqued to 110 ft-lbs. Use a torque wrench to ensure proper tightness. This torque specification applies to all six bolts securing the hitch to the frame.
The CURT 13400 includes: 6 bolts (part 10-10272, 1/2-13 UNC, 1-3/4", Grade 8, zinc-plated), 6 spacers (part CM-SP6, 0.250 x 1.00 x 3.00" square hole), 6 nuts (part 20-00062, serrated flange, 1/2-13 UNC, Grade 8, zinc-plated), and 6 pieces of 1/2" fishwire (part 1_2 FISHWIRE).
1. Lower and remove the spare tire. 2. Remove the two heat shield mounting bolts (rear, 10mm socket each side). 3. Remove the center front attachment point of the spare tire shield (12mm socket) and remove the shield. 4. Remove frame hole plugs and orange tab on both sides; trim heat shield for access. 5. Enlarge the forward-most mounting hole; fishwire the carriage bolt and spacer through frame holes, then reverse fishwire into the forward-most hole on both sides. 6. Reinstall heat shield, raise hitch into place, secure with 1/2" hardware torqued to 110 ft-lbs, and reinstall spare tire.
Safety glasses must be worn at all times while installing this product. Additionally, follow your vehicle owner's manual when lowering and removing the spare tire to avoid injury.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing maintenance is critical for safe towing operation.
The manual states you should periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound, but does not specify an exact interval. Regular inspection before towing is recommended as a best practice.

Yes, the Curt 56040 vehicle-to-trailer connector fits Subaru Forester models from 2009 onwards, including 2009–2013 and 2014+ versions. However, the wiring harness location differs between these model years, so follow the instructions specific to your year. The connector does not fit Subaru Crosstrek or XV Crosstrek Hybrid models.
No. The Curt 56040 is designed for Subaru Crosstrek and XV Crosstrek models, but explicitly excludes Hybrid versions. If you have a Hybrid model, contact Curt Manufacturing or your vehicle manufacturer to confirm compatibility.
The Curt 56040 is rated for Signal Circuits at 3.0 amps per side and Tail/Running Circuits at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as exceeding it can cause loss of warranty, overheating and potential fire.
You will need a 10mm socket, a ratchet, and a panel trim removal tool. These are the only tools specified in the manual. Additional tools such as a drill may be needed if you must drill a pilot hole for the ground screw, depending on whether a suitable existing screw is available in your vehicle.
Yes. The first step of installation is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal. This must be done before proceeding with any other installation steps.
On 2009–2013 Forester models, the vehicle wiring harness connectors are located on the driver side under the trays in the trunk. You must first remove all trunk floor coverings and the plastic fasteners securing the trays in the center and on the driver side to access them.
On Subaru Outback models, the vehicle wiring harness connectors are tucked up behind the driver side inner fender trim, visible near the rubber grommet in the floor and the cargo anchor. You must first remove trunk floor coverings and trays to access this area.
On 2014+ Forester and XV Crosstrek models, the vehicle taillight wiring harness connectors are located on the driver side behind the rear trim panel. Pull back on the rear trim panel to locate them.
Insert the custom connector end into the vehicle connector. Make sure the connectors are fully inserted with locking tabs in place. Do not proceed until the connection is secure and the locking tabs are engaged.
Not necessarily. First, locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, you may drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw if needed. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Locate a flat spot inside the vehicle, near the taillight, and adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and flat to allow the tape to bond securely.
Install a red 10-amp fuse into the in-line fuse holder. This is the maximum fuse rating allowed; do not use a fuse with a higher amperage rating.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent tangling and damage.
After installation, reinstall all items removed during the install and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test the connector for proper function by using a test light or connecting a properly wired trailer.
