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.
RC Crawler Course Accessories - Rocks, Bridges, and Obstacles
Universal Rocks crawler accessories let you customize any RC course layout with realistic rock obstacles, bridge crossings, and terrain features. Each piece is built with the same proprietary technical shell used in our Moab Crawler Course series - natural crushed rock and minerals embedded into the surface for authentic texture and scale-accurate traction.
Rock sets are available in 5-piece and 9-piece configurations, giving you individual boulders and obstacles to scatter across the trail. Use them for tire placement practice, off-camber challenges, breakover sections, or as standalone display pieces. The Moab Arch adds a signature summit feature to any layout, while the Moab Rock Bridge and Weathered Plank Bridge create crossings, transitions, and elevated trail sections that test approach angles and line selection.
Every accessory pairs with our full range of Moab crawler courses. Add a rock set to a compact Mammoth Micro or Moab XS for tighter desktop lines. Bridge pieces work especially well with mid-size courses like the Moab S and Moab M, adding crossings and elevation changes without taking up more floor space. Running a full backyard layout on the Moab L or the 18-foot Moab XL? Spread out a full rock set, add both bridge styles, and create an expandable trail system with unlimited configurations.
Like all Universal Rocks products, crawler accessories are lightweight, weatherproof, and built to last. Use them on a garage floor, in a hobby room, at an event, or leave them outside year-round. They won't crack, rot, or degrade. Move, stack, screw down, or reposition pieces anytime to keep your course fresh and challenging.
Free shipping on all accessories. Pair them with a crawler course for the complete setup, or use them standalone to build something entirely your own.
