A Larger Rock Set for Bigger, More Technical Lines

The 9-Piece RC Crawler Rock Set gives builders more freedom, more variety, and more ways to create a challenging crawler layout. Unlike our standalone crawler courses, this set includes nine individual rock pieces that can be moved, stacked, spaced out, or grouped together to create nearly endless line combinations.

Use the rocks as a standalone obstacle course, spread them across a garage floor, place them in the backyard, or combine them with one of our Universal Rocks crawler courses to add taller climbs, sharper breakovers, side-hilling sections, tire placement challenges, and technical gates. Each rock is lightweight compared to real stone, making it easy to rebuild your course whenever you want a new challenge.

• Course Compatibility: Use as a standalone obstacle set or combine with our crawler courses to expand your terrain and create more advanced lines.
• Utah Red Finish: Exclusive color to the crawler series. We use natural minerals to achieve our colors; some residual color transfer may occur during initial setup and can be washed off with soap and water.

• More Pieces, More Possibilities: With nine individual rocks, this set gives you more ways to build longer routes, split lines, and advanced obstacle sections.
• Great for Practice: Set up quick challenges for testing suspension, tire grip, throttle control, approach angle, side-hilling ability, and breakover clearance.
• Use Indoors or Outdoors: Perfect for garages, hobby rooms, patios, backyards, shops, event displays, and RC crawling practice areas.
• Lightweight Alternative to Real Rock: Get the look of natural rock without hauling heavy stone or committing to a permanent setup.
• Expandable Layout: Add this set to any Universal Rocks crawler course to make your layout larger, more technical, and more customizable.

• Endless Line Options: Space the rocks apart for a trail-style crawl or group them together for a compact, technical obstacle section.
• Stackable & Adjustable: Position rocks beside, behind, or against each other to create taller climbs, steeper approaches, and more demanding routes.
• Designed for Technical Driving: Create tire placement challenges, off-camber sections, breakover points, ledges, and multi-line obstacles.
• Great for Multiple Scales: Ideal for small-scale crawlers and technical practice areas. Larger crawlers can use the rocks as added obstacles, tire placement points, or course markers.
• Realistic Display Value: Adds a natural, scale-looking rock environment for product photos, hobby displays, shops, events, and social media content.
• Handmade in Garland, Texas: Built by Universal Rocks with the same realistic styling used across our crawler, pool, garden, reptile, and commercial products.

• Setup: Place the rocks on a flat surface, crawler course, mat, plywood base, patio, or outdoor area. Reposition as needed to create new lines.
• Placement: For the most stable setup, place each rock open-side down on a flat or supportive surface before crawling.
• Open-Bottom Design: Each rock is open on the bottom and partially hollow inside, helping keep the set lightweight and easy to reposition while still giving the look of real stone.
• Cleaning: Rinse with water or wipe clean as needed. Mild soap can be used for heavier dirt or initial color residue.
• Outdoor Use: Designed to handle outdoor conditions while remaining easy to move and store if needed.
• Tip: For a more technical course, combine this rock set with bridges, gates, wood pieces, elevation changes, or one of our full crawler courses.
