LEGO Technic sets, biggest first

Technic is the engineering side of LEGO® sets: gears, axles, pistons, and models that actually do things. The flagship supercars (Ferrari, Lamborghini, McLaren, Bugatti) get working gearboxes and steering, and the construction machines like the Liebherr excavator are motorized monsters.

The builds here feel different from a regular brick set. You spend hours threading axles and pinning beams, and the payoff is a model that works, not just one that looks right. We've sorted every Technic set in the catalog by piece count. Fair warning: Technic pieces are dense, so a 3,000 piece Technic set takes longer than a 3,000 piece display set.
