Climbers Pack – Build Your Hardline
Made in USA.
Steeper climbs. Technical lines. Bigger challenges. The Climbers Kit brings together the ingredients to create some serious MountainBlox hardlines. Build a challenge, find your line, and keep coming back until you conquer it.
With two Squatch’s Revenge, two Double Summit, two Tunnel Junction, and a Split Bridge, the Climbers Kit packs steep ascents, tricky descents, tunnel passages, and bridge crossings into one versatile kit. Realistic rock textures put tire placement and throttle control to the test, while the modular design lets you rearrange the challenge whenever you’re ready for something new.
Use it on its own for freeplay or add it to an existing MountainBlox Set or other Climbers Packs to open up more demanding crawling possibilities. Position the included orange magnetic gates to mark your Route, then see what you and your rig can handle.
Practice Now. Take on the League Later. Build your skills in tire placement, throttle control, and technical climbing, one challenge at a time. The MountainBlox League (MBXL) is coming soon, bringing organized competition to MountainBlox. Start practicing now, and expand your setup as your ambitions grow. Competition requirements will be published with official MBXL Routes.

Modular. Portable. Realistic.
MountainBlox is modular, portable, and remarkably realistic. Lightweight and easy to transport, it brings the look and feel of true outdoor terrain into any space. Build a compact course in your basement, move it upstairs for an evening of living-room crawling, or pack it up for a meetup with friends. When you connect sets together, the adventure only grows.
Every Blox includes a convenient name tag on the underside, so you’ll always know which set is yours. With MountainBlox, you get professional-level crawling challenges without the hassle of permanent builds or unrealistic obstacles.
More than just terrain, MountainBlox is about connection - sharing the crawl, building bigger together, and strengthening the RC community. From living rooms to local meetups, MountainBlox creates opportunities for crawlers everywhere to come together, compete, and collaborate.
