Build Endless Lines with Moveable Rock Obstacles

The RC Crawler Rock Set is designed for builders who want more freedom, more technical challenges, and more ways to change their course. Unlike our standalone crawler courses, this set includes five individual rock pieces that can be moved, stacked, spaced out, or positioned together to create nearly endless line combinations.

Use them as a standalone obstacle setup, spread them across a garage floor, place them in the backyard, or combine them with one of our crawler courses to add sharper climbs, breakovers, side-hilling sections, and technical gates. Each rock is lightweight compared to real stone, making it easy to move your setup around without sacrificing the realistic look and texture Universal Rocks is known for.

• Course Compatibility: Use as a standalone obstacle set or combine with our crawler courses to expand your terrain and create more advanced lines.

• Construction: Open-bottom, partially hollow design for lightweight handling and easy course adjustments.

• Change Your Course Anytime: Move each rock around to create new climbs, descents, side-hill sections, breakovers, and technical lines.
• Great for Practice: Set up quick challenges for testing suspension, tire grip, throttle control, approach angle, and breakover clearance.
• Use Indoors or Outdoors: Perfect for garages, hobby rooms, patios, backyards, shops, and display 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 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 steeper climbs and more demanding routes.
• 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, 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.
• 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.
• Lightweight Open-Bottom Design: Each rock is open on the bottom and partially hollow inside, making the pieces easier to move, reposition, and arrange without the weight of real stone.
