About the RR-ultra Body

Race-Inspired Trail Performance

The Bittydesign RR-Ultra 1/10 Rock Crawler Pre-Trimmed Body delivers aggressive styling and trail-ready functionality in a compact, modern package. Featuring an oversized traditional bed, massive fender openings, and twin bonnet-mounted turbos, this body shell breaks away from the vintage crawler look with a race-inspired aesthetic.

Designed for 313mm wheelbase rigs, it’s manufactured from high-quality Lexan® polycarbonate for durability and lightweight performance, and comes transparent, pre-cut, and ready for quick customization with included window masks and pre-cut decals.

Precision Meets Realism

With its smaller overall footprint and large fender cutouts, the RR-ultra is perfect for narrow trails and 106mm diameter tires, offering excellent clearance and articulation. Advanced CAD design and 5-axis CNC machining ensure precise details, while optional scale accessories like a full interior, digital steering wheel, mirrors, and more allow for unmatched realism. Whether you're building a performance-driven crawler or a show-ready rig, the RR-ultra brings bold looks and functionality together in a standout shell.
