However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Toyota Yaris iA and Scion iA (to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.

Yes, CURT hitch 11421 is designed for 2016-Present Scion iA and Toyota Yaris iA sedans. Verify your vehicle matches this model and body style before purchasing.
The hitch is rated for a maximum trailer weight of 2000 lbs and tongue weight of 200 lbs when used as a weight-carrying hitch. Never exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Non-trailer (wheel-less) loads can be applied to this hitch only if they are supported by CURT 18050 stabilizing straps. Failure to use stabilizing straps for non-trailer loads will void the product warranty. Consult the CURT catalog or www.curtmfg.com for stabilizing strap information.
CURT hitch 11421 is designed for use with ball mount #45520. Euro mount options are available: #45561 (1 7/8" ball) and #45562 (2" ball).
Required tools are: 11/16" socket, 6" socket extension, ratchet, torque wrench, die grinder, panel removal tool, and safety glasses. A die grinder is needed to enlarge the access hole on the passenger side frame rail.
The kit includes: 4× 7/16-14 UNC carriage bolts (part 10-10282), 4× .250 x 1.00 x 2.50" square hole spacers (CM-SP11), 4× 7/16-14 UNC serrated flange nuts (part 20-00103), and 4× 7/16" fishwires (part 7_16 FISHWIRE).
Yes. Step 1 requires disconnecting three electrical harness pins from the driver side frame rail using a panel removal tool. The harness is reconnected in step 6 through the clearance hole on the driver side frame rail after the hitch is secured.
No drilling is required. However, the access hole on the passenger side frame rail must be enlarged using a die grinder to allow 7/16" carriage bolts and CM-SP11 spacers to pass through. The driver side frame rail uses existing holes.
Fishwires are used to guide the 7/16" carriage bolts and spacers through the frame rail access holes and mounting holes. The fishwires are attached to the bolts, pulled through the holes to guide them into position, then removed before the flange nuts are installed. Keep fishwires attached to prevent loss into 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 improve the quality of the install and reduce installation time.
All 7/16" hardware (carriage bolts and flange nuts) must be torqued to 70 ft-lbs. Use a torque wrench to ensure proper tightening.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.
Safety glasses must be worn at all times while installing this product. Before beginning installation, read all instructions thoroughly. If you are hesitant to undertake this task, contact an authorized CURT installer for assistance. Technical support is available at 877.287.8634.
