Customize your RC crawler course with lightweight, realistic rock sets, bridges, arches, and trail accessories from Universal Rocks. Use them on their own or combine them with our crawler courses to create climbs, crossings, breakovers, side-hilling sections, display areas, and endless new lines.
Move, stack, screw down, or reposition pieces anytime to build a course that fits your space, skill level, and crawler setup.
Build a More Technical RC Crawler Layout
Universal Rocks crawler accessories are made for hobbyists who want more flexibility from their RC crawler course. Instead of one fixed layout, these accessories let you change your setup whenever you want. Add individual rock obstacles for tire placement practice, bridge pieces for crossings and transitions, or the Moab Arch for a more advanced summit challenge.
Our RC crawler accessories are lightweight compared to real rock, making them easier to move, store, and reposition while still giving your course a realistic natural look. They can be used indoors, outdoors, in garages, hobby rooms, backyards, display areas, shops, or event setups.
Whether you are building a compact course for small-scale crawlers or adding technical sections to a larger setup, these accessories help create more variety, more skill-building opportunities, and more realistic trail-style crawling.
