LEGO SET 42134 - Alternate build | Monster Jam Megalodon
LEGO Technic’s Monster Jam Megalodon (42134-1) is already a beast on wheels—but its versatile parts also unlock a sea of creative possibilities. From high-speed racers to rugged off-roaders, builders around the world have reimagined this set into machines that defy its original design intent. Whether you’re looking to experiment with alternative drivetrains, explore Articulated steering techniques, or simply give your Technic collection fresh life, these community MOCs offer plenty of inspiration .
Each of the following builds uses only the pieces included in 42134-1, proving that with a bit of ingenuity, a single set can spawn dozens of unique models. Feel free to mix and match ideas—maybe merge the chassis of the Quadbike with the shark-toothed look of the Killer Mouth Car, or adapt the PullBack MOCS mechanism to power a Batmobile-style cruiser. Let these designs spark your next Technic experiment!
