This LEGO ball joint set includes three pairs of 1x4 plates with integrated socket and ball connections, designed for articulated movement within standard LEGO builds. Each plate combines structural support with a compact pivot point for controlled rotation.

1x4 LEGO Ball Joint Plate Design & Connection

Each LEGO socket joint plate features a built-in ball or socket element mounted on a 1x4 plate base. This allows direct integration into LEGO plate and brick systems while maintaining smooth articulation between connected sections.

LEGO System & Technic Compatibility

These LEGO ball and socket elements bridge standard LEGO building and Technic-style movement. They can be embedded in vehicle frames, structural builds, and articulated assemblies without requiring full Technic conversion.
