This model comes as a ready-to-run package with 2.4GHz radio control, making it accessible for beginners while offering room for upgrades and tuning by enthusiasts.
1/10 RC Crawler Chassis Kit
This DIY chassis kit is designed for 1/10-scale RC crawlers with a 313mm wheelbase, compatible with popular models like Axial SCX10 and TRX4. It uses a durable nylon frame and axle housing to balance rigidity with flexibility. The kit includes a two-speed gearbox and a 35T 550 brushed motor, delivering strong torque for demanding off-road sections. Builders can leverage the chassis to customize driveline layout, gearing, and suspension to suit their preferred crawling style and terrain challenges.
Carbon Fiber Frame Rail Kit With Ultralight Transmission Skid
This chassis kit emphasizes weight reduction and strength with carbon fiber rails and panels. It integrates a skid plate design optimized for 90-degree obstacle handling, plus an adjustable transfer case for controlling drive ratios. The kit supports 1/10-scale crawlers and helps maximize ground clearance while maintaining stable geometry for challenging climbs, descent maneuvers, and torque management. It suits builders aiming for a lighter, more responsive rig without sacrificing durability.
633Pcs Universal RC Screw Kit
This comprehensive set provides 633 pieces of hardware including M3 and M4 socket screws, lock nuts, dowel pins, and E-clips designed for hobby-grade crawler builds. The kit covers repairs, upgrades, and spare parts across a wide range of brands, including Axial, Redcat, and SCX vehicles. Precision machining, black oxide coating for corrosion resistance, and assorted sizes help users address loose fasteners, gear mounts, and chassis upgrades quickly and reliably.
INJORA 4LED Rock Lights Kit
Upgrade crawlers with a 4-LED rock lights kit featuring CNC-machined aluminum mounts and a compact 4-LED setup ideal for 1/10 scale SCX10 and TRX4 models. The kit includes mounting hardware and cabling for a clean installation that improves trail visibility at night and enhances the vehicle’s scale appearance. The lights are designed to be unobtrusive yet highly effective in illuminating rock features, crevices, and brush lines on dim trails.
RC Repair Work Stand and 532-Piece Screw Kit
This multi-piece kit combines a rotary repair stand with a broad 532-piece screw set, offering a complete repair and upgrade solution for 1/8 to 1/18 scale crawler platforms. The stand rotates 360 degrees and adjusts height for easy access to wheels, suspensions, and drivetrains. The included screws, dowels, nuts, and washers support general maintenance and customization, enabling precise alignment and secure mounting during field repairs or workshop sessions.
Buying Guide
- Scale and compatibility: Verify wheelbase, chassis width, and mounting standards to ensure parts fit your current crawler or intended build.
- Material and weight: Carbon fiber frames offer strength with lightness but come at a higher cost; nylon frames provide durability at a lower price point.
- Upgrade vs. stock: Consider whether you need a full kit or selective upgrades (e.g., light kit, robust screws, or a new chassis) to achieve your crawl goals.
- Maintenance and repair readiness: A comprehensive screw kit or repair stand reduces downtime during field repairs and preserves components under high-torque crawling.
- Power and control: If upgrading drivetrains or gearing, ensure the motor, transmission, and ESC are compatible and suited for the terrain you frequent.
- Aesthetics vs. function: Scale details like licensed body shells and realistic wheels improve appearance, while functional additions (ground clearance, torque) affect performance.
- Installation considerations: Some kits require advanced assembly; others are plug-and-play. Check included hardware and required tools before purchase.
