This is the URB Ultra "Jimmy's 4x4 Moonbuggy" 1/10 4WS Rock Crawler Kit from Vanquish Products. Built for serious rock crawling and technical trail performance, this kit combines scale realism with competition-ready engineering. Its four-wheel steering buggy platform is designed to tackle challenging terrain with precision and control. With premium materials and licensed components, it offers an engaging and highly customizable build experience.
Advanced LFD Transmission System
At the core of the URB Ultra is the LFD transmission, engineered for strength, efficiency, and smooth operation. Featuring precision-machined hardened gears and durable steel shafts, it delivers reliable power transfer under demanding conditions. Features an integrated dig unit with an included aluminum servo horn that is designed specifically to fit a low-profile servo and allows the rear drivetrain to be disengaged, enabling tighter turning and improved maneuverability on technical terrain. This system gives drivers a clear advantage when navigating complex rock sections!
Wide Stance F10W Axle Performance
The aluminum F10W axles provide a wider and stronger platform, increasing stability without sacrificing clearance. With a wider track width compared to standard portals, the vehicle maintains better balance on uneven surfaces. The offset pumpkin design enhances both steering angle and ground clearance, improving overall capability. This setup ensures confident handling and optimized traction in rugged environments.
Scale Suspension and Wheel Optimization
Equipped with officially licensed FOX S8I oil-filled shocks, the URB Ultra delivers realistic performance and excellent suspension response. Dual internal springs and precision components allow for smooth articulation and consistent damping. Paired with high-offset Crawl Spec Sierra wheels, the setup improves scrub radius and steering efficiency. Together, these components create a stable, responsive, and highly capable rock crawling platform.
CNC Aluminum Cage Design
One of the most distinctive features of this kit is the officially licensed Jimmy's 4x4 CNC aluminum cage, which sets it apart from typical rock crawler builds. This precision machined structure offers exceptional strength and rigidity, providing both durability and protection in harsh crawling conditions. Beyond performance, the cage delivers an unmatched level of scale realism that closely replicates full size competition buggies.
