Purpose and function of the towing hitch

The presented rear trailer hitch is a component from the Trailer hitches and complete sets group, designed to operate in the rear body zone. Its task is to transfer loads associated with towing a trailer, bicycle rack, or transport platform, while maintaining the appropriate rigidity and stability of the system.

The placement in the rear part of the vehicle allows for optimal distribution of forces acting on the body structure, which is important for both driving safety and the durability of suspension and chassis components.

Construction and fitment for BMW E90 / E91

The Witter BM24CU towing hitch has been developed specifically for the BMW 3 Series E90/E91 platform, ensuring it maintains the correct mounting points and compatibility with the manufacturer's factory solutions. Proper fitment translates into:

• secure seating in the rear part of the body,
• proper cooperation with the bumper beam and chassis components,
• preservation of the geometry intended by the vehicle manufacturer.

Thanks to this, the installation proceeds in an orderly manner, without the need for non-factory structural modifications.

Benefits of using an original BMW hitch

Using an original towing hitch in a BMW 3 Series allows for maintaining the consistency of the entire towing system with other vehicle components. The most important advantages include:

• factory fitment to the body and chassis structure,
• preservation of the connection rigidity intended by the manufacturer,
• possibility of seamless cooperation with other elements of the towing system.

A used component of this type is a good solution for post-accident repairs or when retrofitting the car with towing functionality, where compliance with OEM solutions is a priority.

Condition of the component and installation aspects

The towing hitch is offered in a used condition, which means that before installation, it is worth verifying the condition of the working surfaces, threads, and mounting points for potential cleaning or maintenance. A properly prepared component will ensure a stable connection to the body and long-term operation.

Installation in a specialized service center is recommended to ensure proper tightening of bolted connections, geometry control, and compliance with applicable regulations regarding trailer towing.
