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 Forester (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 400 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 09 - 13 Subaru Forester Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13147 (Part #5W-CHW-2752) fits 2009-2013 Subaru Forester models. The 2013 model year is the last year covered by this part number. For newer models, check for an updated version.
The 09 - 13 Subaru Forester Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13147 (Part #5W-CHW-2752) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The manual does not provide the specific gross load capacity value. Contact Curt Manufacturing technical support at 1-877-287-8634 for this specification.
Yes, Curt part 13147 is designed for the Subaru Forester. However, you must verify that your vehicle's exhaust system can be lowered and that the frame rail holes can be modified as described in the installation instructions. If you have questions about your specific model year or configuration, contact Curt technical support at 1-877-287-8634.
Do not exceed your vehicle manufacturer's recommended towing capacity. The hitch itself has a gross load capacity, but your vehicle's engine, transmission, brakes and frame set the actual limit. Consult your Subaru owner's manual for the maximum towing weight your Forester can safely handle.
Non-trailer loads applied to this hitch must be supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. Do not rely on the hitch alone to carry cargo.
You will need: flat screwdriver, die grinder with carbide bit (or round file), drill, 17/32" drill bit, ratchet, 3/4" socket, 10" extension, and torque wrench.
The kit includes: two 1/2" fishwire, four 1/2-13 UNC grade 8 carriage bolts (1-1/2" long, yellow zinc plated), four 0.250 x 1.00 x 2.50" square hole spacers (CM-SP10), and four 1/2-13 UNC grade 8 serrated flange nuts (yellow zinc plated).
Yes. You must lower the exhaust for ease of installation. This requires removing five rubber hangers. Use a spray lubricant or soapy water on the hanger rod and isolator to ease removal. The exhaust is re-installed after the hitch is secured.
Yes. You must remove the frame rail hole plugs using a screwdriver, then enlarge and modify the holes. One hole ("A") requires modification using a die grinder or round file to allow insertion of the 1/2-13 bolts and CM-SP10 spacers. The other hole ("B") requires enlargement using a 17/32" drill bit to allow the 1/2-13 bolt threads to protrude through the frame rail. Refer to the Heat Shield Diagram in the manual for exact locations.
Fishwire is a technique to insert fasteners into holes that are difficult to access. The manual includes a "Fishwire Technique" diagram and a "Reverse Pull Fishwire Technique" diagram showing how to thread the 1/2-13 carriage bolts and CM-SP10 spacers into holes A and B respectively. Refer to these diagrams in the manual for the step-by-step procedure.
All 1/2-13 fasteners must be torqued to 110 lb-ft. Use a torque wrench to ensure proper tightness.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. No specific interval is stated in the manual; contact Curt technical support at 1-877-287-8634 for recommended maintenance intervals.

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.
