Monster Jam Max-D

The LEGO® Monster Jam Max-D (set 42119) is a 230-piece LEGO Technic set released in 2021, capturing the spiked silhouette of the famous Monster Jam Maximum Destruction truck. The 2-in-1 model carries authentic Max-D graphics, signature spikes, and a movable flag, with a built-in pull-back motor that launches the truck across the floor for stunt action. Once kids are done with the truck, the same bricks rebuild into a pull-back quad bike for a second high-speed adventure. A licensed Monster Jam build that ties Technic engineering to real arena spectacle.
