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 535 and 550 (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.

Yes. Before drilling, you must clear the trunk pan of all contents and slide the battery towards the rear of the vehicle. After drilling and final assembly, slide the battery back into position and reinstall carpet and trunk contents.
Two people may be required to ease installation. However, the manual does not specify whether a second person is mandatory or optional.

Yes. After drilling and final assembly, you must trim the underbody panel as required before reinstalling it onto the vehicle. Tin snips or aviation shears are provided in the required tools list for this purpose.
All 1/2" fasteners must be torqued to 110 lb-ft. This applies to the carriage bolts and hex flange nuts used throughout the installation.
The kit includes: (4) 1/2-13 x 1 1/4" carriage bolts Grade 8, (2) 1/2-13 x 2" carriage bolts Grade 8, (6) HFN 1213 Grade 8 hex flange nuts, (2) CM-SP6 spacers (.250 x 1.00 x 3.00" square hole), (2) CM-SP4 spacers (.250 x 1.50 x 3.00" square hole), (2) CM-SP55 spacers (.375 x 1.25 x 2.50" round hole), (2) 1/2" fishwire, and (1) 11381-TB tail bracket.
