LEGO® Mack LR Electric Garbage Truck

The Mack LR Electric is a real electric refuse truck built by Mack Trucks, and LEGO® Technic set 42167 recreates it as a scaled-down model. At 503 pieces and 125 different elements, it's one of the more compact Technic sets from the 2024 lineup, built the Technic way with pins, axles and connectors rather than classic bricks.

Description

Modelled on a truck that actually exists

Unlike a lot of LEGO vehicles, this one is based on a real machine already on the road in several US cities. The set captures the boxy, upright cab shape and the truck's distinctive front end. Its colour scheme of Black, White, Light Bluish Gray and Red mirrors the liveries used on real refuse trucks, giving the finished model a working-vehicle look rather than a toy-bright one. That closeness to the real vehicle is part of the appeal for adult builders who enjoy seeing everyday machinery translated into brick form.

Technic construction, pin by pin

With 503 pieces and 125 different elements, the chassis goes together from pins, axles and connectors in the usual Technic way, which takes a bit more attention than a standard brick build but leaves you with a sturdier model that has moving parts under the surface. The parts list on this page covers every specialised element used in the chassis, cab and body, useful if you're hunting for a particular connector or axle length for another project.

A compact build, no minifigures

There are no minifigures in this set, which is standard for a Technic vehicle at this scale, the focus sits on the mechanics and the accurate look rather than a play scene. At 503 pieces, it's a manageable build for a single evening rather than a multi-day project. Even at this size, the cab keeps enough surface detail to read clearly as a refuse truck, with a recognisable silhouette that holds up on a shelf as well as at eye level.

Who it suits

The Mack LR Electric suits anyone who likes real-world trucks and machinery, as well as collectors already building out the Technic vehicle range. It's also a reasonable entry point if you haven't tried a Technic set before, since the piece count stays modest. Check the full colour and parts breakdown on this page before comparing it with other Technic vehicles, particularly if you're matching black, white and red parts against sets already on your shelf.
