Connect to your lifestyle with a custom hitch receiver from CURT. All of our custom hitches are designed for a vehicle-specific fit, manufactured with pride, finished for industry-leading rust resistance and tested to rigorous SAE J684 standards for safety. This class 1 trailer hitch and ball mount combination is designed for a custom fit on select years of the Cadillac CTS and STS (see application info to verify fitment). The hitch integrates with the vehicle's frame and provides a useful and dependable 1-1/4" x 1-1/4" receiver. The receiver is perfect for attaching the included ball mount and towing a small trailer, or for adding cargo space with a hitch-mounted cargo carrier, bike rack or other accessory. This particular class 1 hitch is rated for 2,000 pounds gross trailer weight and 200 pounds tongue weight (never exceed the lowest-rated towing component). The ball mount included with this trailer hitch quickly and easily installs into the hitch receiver and has a 3/4" trailer ball hole (trailer ball not included). It can be mounted in the rise or drop position to promote level towing. Like all CURT custom hitches, this class 1 hitch is protected with our co-cured finishing process. It is descaled for a smooth surface, immersed in liquid A-coat for rust resistance inside and out, covered with a durable black powder coat and finally co-cured for an industry-leading rust, chip and UV-resistant shield. No matter where you're headed or which season of the year you’re towing in, this CURT hitch is equipped for long-lasting resilience to the elements. It features an open-back receiver for easy cleaning, and it comes with all the hardware necessary for the installation.
Trailer hitch weight ratings are limited to vehicle manufacturer's stated capacities
Not compatible for use with vertical hanging bicycles (bike racks that require the bicycles to be hung / mounted vertically)
Includes ball mount #45522, installation hardware, pin & clip

Yes, part number 11307 is designed for Cadillac CTS and STS 4-door sedans. This hitch is designed for use with ball mount D-221 / 45522.
The kit includes: 6 carriage bolts (7/16-14 x 1 3/4), 2 spacer plates (CM-11307-SP), and 6 hex flange nuts (7/16-14). All fasteners are required for installation.
You must remove the spare tire cover to access the trunk floor, but the manual does not explicitly 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. Before installation, you must lower the muffler by removing the two rearmost exhaust hangers and the one forward exhaust hanger. These three hangers must be reinstalled after the hitch is secured.
Yes, drilling is required. You will 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 diameter. Installation begins with 1/8 inch pilot holes, which are then enlarged to 1/2 inch.
All fasteners must be tightened to 70 lb-ft.
Raise the hitch into position and align the rear edge of the hitch side plate flush against the frame end plate. Center the hitch from side to side. Use the hitch as a template to mark and center punch the three mounting holes on both sides before drilling.
The two spacer plates (CM-11307-SP) are positioned over the mounting holes inside the trunk. The carriage bolts pass through the spacer plates and the trunk pan before being secured with flange nuts on the outside.
All 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.
All holes drilled in the vehicle must be sealed to prevent entry of exhaust fumes into the trunk. This is a critical safety step to protect occupants.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an exact interval, but regular inspection is essential for safe operation.
