Technic Pin Connector Block - Liftarm 1 x 3 x 3 (Part 32557)
The Ultimate Multi-Directional Connector
Create incredibly strong and complex connections with the LEGO® Technic 1x3x3 Pin Connector Block (Part 39793). This is not a simple liftarm; it's a dense connection hub designed to be the central joining point for multiple beams and axles. With a total of nine connection points (five pin holes and four axle holes) facing in three different directions, this piece is the solution for advanced frame-building challenges.
This powerhouse part is a key component in our extensive collection of Technic Pins and Connectors.
Engineered for Maximum Rigidity
The primary function of this block is to create exceptionally rigid structural intersections. It allows you to connect beams horizontally, vertically, and crosswise through a single, solid point, minimizing flex and wobble in your largest and most complex creations.
Creative Building Applications:
- Vehicle Chassis Cross-Bracing: Use it as the central node to connect the main beams of a large truck or car chassis for superior strength.
- Mech and Robot Torsos: Build the incredibly strong core of a large-scale robot, attaching the arms, legs, and spine to this single block.
- Crane Superstructures: Form the rigid intersection points in the lattice boom of a heavy-duty crane.
- Complex Gearbox Casings: Construct a sturdy housing for a multi-stage gearbox, using the various connection points to mount axles and gears.
Combine this block with parts from our Technic beams and LEGO® Technic Pieces collections to engineer your most ambitious models yet.
LEGO® parts are intended for builders aged 4 and up. They may pose a choking hazard for children under 3 years old.
