GraviTrax Expansion Sets

Extend your GraviTrax for even more fun

If you’ve tried everything you can think of with your GraviTrax marble run starter set and you’re ready for more, you need our GraviTrax extension sets. Each one has a different theme - like bridges or tunnels - and comes packed with cool new parts to extend your marble runs in new and exciting ways.

Let your imagination run wild

GraviTrax expansion sets don’t just add more of the same to your starter set. You’ll get all sorts of different new parts that open up new avenues of creative possibilities. Build higher and faster than you’ve ever built before, and harness the power of magnetism, kinetic energy and gravity to move your marble in ways you never thought possible.

Extend your GraviTrax with Power or Pro?

If you want to use the power of electronics to build and control your marble run designs, you need a GraviTrax power extension kit. Or, if you want to build as high as possible, check out the GraviTrax Pro Vertical extension set.
