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 750 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 5,000 lbs. WD and 750 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 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, in Step 9 you must use a hammer to bend the bumper mounting flange inward toward the front of the vehicle to allow the hitch to mount flush. This is a permanent modification to the bumper beam.
All M10 hardware (the supplied M10 bolts and factory M10 nuts) must be torqued to 48 lb-ft.
Installation follows 11 steps: (1) remove 6 plastic expanding fasteners from fascia bottom, (2) remove splash guards with 8 mm bolts, (3) remove expanding fasteners under splash guards, (4) remove push rivets from wheel wells, (5) remove taillight panel bolts with 10 mm socket, (6) remove fascia by pulling gently and unplugging wires, (7) remove 2 wire harnesses from bumper top, (8) remove 3 M10 bolts and 1 M10 nut from each side with 17 mm socket, (9) bend bumper mounting flange inward with hammer, (10) raise hitch over bumper studs, install supplied bolts and washers, attach wire harnesses and zip tie, torque all M10 hardware to 48 lb-ft, (11) reinstall fascia in reverse order and reconnect plugs.
Remove fascia in this order: (1) remove 6 plastic expanding fasteners from the bottom, (2) remove 2 bolts from each splash guard using 8 mm socket, (3) remove 1 expanding fastener under each splash guard, (4) remove 1 push rivet from each wheel well by depressing the center with a screwdriver (use panel removal tool to pry out), (5) open liftgate and remove panel near taillight on both sides by pulling straight back from the top, remove the 1 bolt connecting fascia to vehicle body on each side using 10 mm socket, (6) starting from wheel well and working toward center, pull fascia gently and unplug any attached wires. Set all removed parts aside for reinstallation.
After removing the fascia and wire harnesses, remove the bumper beam by unbolting it from the frame. Using a 17 mm socket, remove 3 M10 bolts and 1 M10 nut from each side (6 bolts and 2 nuts total). Set the nuts aside for reattachment in Step 10. Return the bumper beam and bolts to the vehicle owner.
Raise the hitch into position by placing it over the bumper studs on both sides of the frame. Secure the factory M10 nuts that were removed in Step 8. Install the supplied M10 bolts and conical washers. Attach the 2 wire harnesses to the top of the hitch and secure them with the 2 supplied cable ties. Torque all M10 hardware to 48 lb-ft.
Reinstall the fascia in reverse order of removal (Steps 1-6). Be sure to reconnect all plugs that were disconnected during fascia removal. Note that the fascia has a removable panel for hitch usage; this panel can be removed when using the hitch and reinstalled when the hitch is not in use.
