Create perfectly rigid 90-degree angles in your builds with the LEGO® Technic 2x4 L-Shaped Thick Liftarm (Part 32140). This is one of the most fundamental structural elements for building a strong and reliable chassis or frame. Its "thick" one-brick-high profile ensures maximum rigidity, preventing twisting and bending at critical connection points.
This essential framing piece is a staple in our comprehensive collection of LEGO® Technic Beams.
Engineered for Maximum Structural Integrity
Unlike building right angles from separate beams and connectors, this single, solid piece guarantees a perfect and durable corner every time. It is the go-to solution for any application where strength and precision are paramount.
Creative Building Applications:
Vehicle Chassis Corners: Form the strong, square corners for the chassis of a truck, car, or rover.
Gearbox Mounts and Casings: Build a rigid housing for complex gear systems that won't flex under load.
Structural Bracing: Use it as a powerful corner brace to reinforce large frames and superstructures.
Mounting Brackets: Create a sturdy, offset mounting point for motors and engines or other functional components.
Secure this liftarm into your creations using a variety of Technic pins and connectors to lock your frame together.
