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 BMW 228, 320, 328, 335, 340, 428, 435 and 440 (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 #45521, pin & clip (Uses pre-existing vehicle hardware for installation)
