A Fundamental Technic Building Block

The LEGO® Technic 1x3 Thick Liftarm (Part 32523) is one of the most essential and versatile parts for any builder. As a "thick" liftarm, it stands one full brick high, providing exceptional strength and rigidity in a compact form. It is the go-to piece for creating strong frames, compact linkages, and sturdy support structures in any build, from simple machines to complex vehicles.

This part is a staple in any builder's collection and a core component of our wider assortment of LEGO® Technic Beams.

Engineered for Strength in Tight Spaces

The utility of the 1x3 liftarm lies in its combination of strength and size. It's short enough to fit into tight mechanical assemblies but robust enough to serve as a key structural element. This makes it invaluable for reinforcing connections, creating small gearboxes, or building the chassis for smaller-scale models.

Creative Building Applications:

• Compact Mechanical Linkages: Design intricate steering systems or functional levers in a small footprint.
• Frame Reinforcement: Use it to create strong right-angle connections between larger beams.
• Mounting Points: A perfect, sturdy point for mounting motors and engines or other functional elements.
• Small-Scale Chassis: Build the durable base frame for a small car, cart, or robotic creation.

Secure this liftarm into your creations using a variety of components from our Technic Pins and Connectors collection.
