6 Pairs LEGO Socket & Ball Parts (Trailer Hitches)

This pack includes six pairs of LEGO® socket and ball joint connectors, commonly used as trailer hitches or articulation joints in custom builds. These versatile parts create strong pivot connections between vehicles, trailers, machines, or articulated models.

LEGO® Socket and Ball Joint Connections

The classic ball-and-socket connection provides a secure joint that can rotate smoothly while staying firmly attached. This makes these parts ideal for linking moving sections of a build or creating flexible connections between components.

• 6 pairs of socket and ball joint parts
• Strong pivot connection for trailers and articulated builds
• Compatible with many vehicle and mechanical builds
• Useful for moving sections, rotating joints, and modular connections

Useful for Vehicle and Mechanical Builds

These parts are commonly used for trailer hitches, allowing trucks, tractors, or other vehicles to tow carts and trailers. The same joint system also works well for articulated machinery, pivoting vehicle frames, or rotating sections in mechanical builds.
