Description

A licensed vehicle from Monster Jam

Grave Digger is one of the most recognisable trucks on the US Monster Jam circuit, known for its green flame graphics on a black body. Set 42118 translates that look into Technic building, with the same oversized wheels and tall, boxy body shape. For Monster Jam fans, it's one of relatively few LEGO® sets built around a real, existing truck design. That green-on-black livery makes the truck easy to identify even at a glance. Even without knowing the real show, the unusual silhouette makes it obvious at a glance that this is a monster truck rather than an ordinary vehicle.

Mechanics take the place of minifigures

Technic sets skip minifigures altogether and focus on working mechanics instead. In 42118 that means a moving wheel suspension and a flywheel drive: give the truck a push and the flywheel keeps it rolling across the floor without any motor or remote control. Those mechanical parts are less eye-catching than a colourful minifigure at first glance, but they're really the point of the set. For anyone curious about how things work, that's exactly what sets Technic apart from themed play sets. For children who enjoy figuring out how things work, that interplay between flywheel and suspension is really the main appeal of the set.

Black, blue and lime as contrast colours

The black, blue, lime and light bluish grey palette leans into the strong contrasts seen on the real Grave Digger truck. With 57 unique parts out of 212 pieces, the part variety is lower than in many similarly sized sets, which is typical for Technic models built from a lot of matching functional pieces. The parts list shows just how many axles, pins and connectors go into the drivetrain. These repeating functional pieces also combine well with other small Technic sets, useful for testing out your own chassis or drivetrain ideas.

A compact set for on the go

With no minifigures and only 57 unique parts, 42118 works well as a compact Technic build for a shorter session, or as an entry point into functional LEGO® vehicles. For collectors of Monster Jam trucks, it's also a natural addition alongside other vehicles from the same line. With hardly any small loose pieces, the build also travels well, making it a good option for a train journey or a holiday.
