All Hardware and Installation Instructions Included!
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 Cadillac CTS and STS (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.
CURT custom wiring is the easiest way to outfit your vehicle with a trailer wiring connection. Each harness is engineered for a specific make and model and uses an OEM-compatible plug, so no cutting or splicing is required during installation. Provides a 4-way flat connector socket for tail lights, brake lights and turn signals. Includes a dust cover and is backed by a limited one-year warranty.

Yes, part number 11307 is designed for Cadillac CTS and STS 4 door sedans. It is compatible with both models.
The Curt 11307 is designed for use with ball mount part number D-221 / 45522.
The manual lists a gross load capacity of 2,000 lbs trailer weight and 200 lbs tongue weight when used as a weight carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower. Check your vehicle's owner manual for the maximum towing limit.
The kit includes 6 carriage bolts (7/16-14 UNC, 1-3/4 inch, grade 8, part number 10-10314), 6 serrated flange nuts (7/16-14 UNC, grade 8, part number 20-00103), and 2 spacer plates (part number CM-11307-SP).
You need to remove the spare tire cover to access the trunk floor, but the manual does not state whether the spare tire itself must be removed. You will need to roll back the trunk carpet and padding to expose the bare metal floor of the trunk pan where the mounting holes are drilled.
Yes, lowering the exhaust is required. You must remove the two rearmost exhaust hangers and one forward exhaust hanger to lower the muffler(s) and provide clearance for hitch installation. After installation is complete, reinstall all three exhaust hangers.
Yes, drilling is required. You must drill three mounting holes on each side of the vehicle (six holes total) through the trunk pan. The process involves drilling 1/8 inch pilot holes first, then enlarging them to 1/2 inch. All drilled holes must be sealed to prevent exhaust fumes from entering the trunk.
The final mounting holes are 1/2 inch in diameter. The installation process begins with 1/8 inch pilot holes, which are then enlarged to 1/2 inch.
All fasteners must be tightened to 70 lb-ft.
Non-trailer loads can be applied to this hitch only if they are fully supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty.
All holes drilled in the vehicle must be sealed to prevent entry of exhaust fumes into the trunk. This is a critical safety measure to protect occupants.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain safe operation and prevent loosening of components due to vibration and use.
