All Hardware and Installation Instructions Included!
Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Subaru Crosstrek (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
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.

Yes, CURT part number 12184 is designed for 2018-Present Subaru Crosstrek 5-Door models. Verify your vehicle matches this specification before purchasing.
The CURT 12184 is rated for a maximum trailer weight of 3,500 lbs and a tongue weight of 350 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
No. The manual states that all non-trailer (wheel-less) loads applied to this hitch must be supported by CURT 18050 stabilizing straps. Do not use the hitch alone for cargo carriers or similar equipment. See the CURT catalog or visit www.curtmfg.com for information on the 18050 straps.
The CURT 12184 is designed for use with ball mount part number 45521. Euro mount options are available as part numbers 45571 (1-7/8" ball) and 45572 (2" ball).
You will need: a ratchet, 3/4" socket, die grinder, torque wrench, and safety glasses. The die grinder is required to enlarge the access holes in the frame rails.
Two people may be required to ease installation. While one person may be able to complete the installation, having a second person will help with positioning and holding the hitch during the process.
The manual does not specify whether battery disconnection is required. Contact CURT Technical Support at 877-287-8634 for clarification on this step.
No drilling is required. However, you must enlarge the existing access holes in the frame rails using a die grinder. The manual specifies that you enlarge access holes and then use fishwire to thread the bolts and spacers into position.
The kit includes: 4× 1/2"-13 UNC carriage bolts, 1-1/2" long, Grade 8 (part 10-10287); 4× 1/2"-13 UNC serrated flange nuts, Grade 8 (part 20-00062); 4× square hole spacers 0.250" × 1.00" × 3.00" (part CM-SP6); 2× round hole spacers 0.250" × 1.50" × 2.00" (part CM-SP16); and 4× 1/2" fishwires (part 1_2 FISHWIRE).
1. Remove 2 rubber plugs from each frame rail (leave center plugs in place) and return them to the vehicle owner. 2. Enlarge access holes and use fishwire to thread 1/2" carriage bolts and CM-SP6 spacers into position; reverse fishwire the remaining bolts and spacers into the access hole. Leave fishwires attached. 3. Raise the hitch into position using CM-SP16 spacers to level as necessary. Remove fishwires and loosely install the 4 hex flange nuts. Do not push bolts into the frame. 4. Torque all 1/2" fasteners to 110 lb-ft.
All 1/2" fasteners must be torqued to 110 lb-ft. This includes the 1/2"-13 UNC carriage bolts and serrated flange nuts.
Two types of spacers are used: CM-SP6 square hole spacers (0.250" × 1.00" × 3.00") are installed with the bolts to position the hitch on the frame rails. CM-SP16 round hole spacers (0.250" × 1.50" × 2.00") are used to level the hitch as required during step 3. The spacers ensure proper alignment and level installation.
Fishwires are tools used to thread the bolts and spacers through the enlarged access holes in the frame rails. The process involves: (1) using fishwire to thread the first set of 1/2" carriage bolts and CM-SP6 spacers into position, then (2) reverse fishwiring the remaining bolts and spacers into the access hole. The fishwires are left attached until step 3, when the hitch is raised into position and the fishwires are removed before installing the nuts.
No. In step 3, after removing the fishwires, you should loosely install the 4 hex flange nuts. Do not fully tighten them at this stage. The fasteners are only fully torqued to 110 lb-ft in step 4, after the hitch is positioned and leveled.
Safety glasses must be worn at all times while installing this product. Additionally, be careful not to push the bolts into the frame during installation. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing inspection is important 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 inspection interval. For specific maintenance schedules, contact CURT Technical Support at 877-287-8634.

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.
