Overview
The AXIAL Transmission, Assembled: SCX30 Z-AXI-3311 is a complete, fully assembled transmission unit designed specifically for the Axial 1/30 SCX30 series of RC rock crawlers. Whether you're restoring a damaged transmission, upgrading your RC car UK collection, or simply keeping spare parts on hand, this OEM transmission assembly delivers the precision engineering and reliability that Axial is renowned for. The SCX30 platform has become increasingly popular amongst UK RC enthusiasts who appreciate the scale detail and authentic rock crawling capabilities of these compact 1/30 scale vehicles.
This isn't just a transmission component—it's a complete drivetrain solution that includes all the gears, shafts, bearings, and fasteners needed to restore or replace your vehicle's transmission system. The fully assembled nature of this product means you get a tested, ready-to-install unit that eliminates the need for complex assembly and potential fitment issues. Whether you're an experienced RC hobbyist maintaining your brushed rock crawler or someone new to RC model repair, this transmission assembly represents excellent value and genuine Axial quality.
Compatible with multiple SCX30 variants including the Ford Bronco 4X4 RTR, Chevrolet K10 4x4 RTR, and Jeep Wrangler JLU 4X4 RTR rock crawlers, this transmission is an essential spare part to keep in your RC toolbox. The worm gear driven system provides the low-speed torque and precise control that makes these vehicles so capable in demanding terrain.
Key Features
- Fully Assembled Unit — This transmission comes completely assembled and tested, meaning you can install it straight away without needing to disassemble, clean, or adjust individual components, saving you time and reducing the risk of assembly errors.
- Genuine Axial OEM Part — As an official Axial factory part, this transmission is manufactured to exact specifications and uses genuine materials, ensuring compatibility and longevity with your SCX30 rock crawler.
- Worm Gear Drive System — The transmission features a sophisticated worm gear arrangement with 2/12T pinion and 16T ring gears, providing excellent torque characteristics and precise control essential for technical rock crawling.
- Precision Engineered Gears — Includes a Mod 0.3 transfer gear (30T) and idler gear (40T) that drive the worm gears, manufactured to tight tolerances for smooth, reliable power delivery and minimal backlash.
- Complete Component Set — You receive not just the main transmission gears and shafts, but also the upper and lower transmission cases, skid plate, motor plate, all necessary fasteners, and precision ball bearings, giving you everything needed for installation.
- Quality Ball Bearings — Features both 3mm x 6mm x 2mm and 3mm x 6mm x 2.5mm ball bearings for smooth shaft rotation and extended component life, reducing friction and wear during extended RC rock crawling sessions.
- Comprehensive Hardware Included — Comes with all necessary fasteners including M1.4, M1.0 button head screws in various lengths, and an O-ring, eliminating the need to source additional parts separately.
Technical Performance
The AXIAL Transmission, Assembled: SCX30 Z-AXI-3311 represents professional-grade RC drivetrain engineering designed for the demanding requirements of 1/30 scale rock crawling. The transmission utilises a worm gear arrangement that is specifically engineered to provide the low-speed torque and precise throttle control necessary for navigating technical terrain, obstacles, and challenging crawling scenarios. The 2/12T worm pinion gear meshes with the 16T ring gear, creating gear ratios that optimise the power delivery characteristics for this scale of vehicle. The inclusion of both sizes of precision ball bearings (2mm and 2.5mm thickness variants) ensures minimal friction and exceptional rotational smoothness across all shaft positions. The Mod 0.3 specification on the transfer and idler gears indicates professional-grade tooth profile accuracy, which directly translates to quieter operation, reduced vibration, and extended component lifespan. The transmission cases—upper, lower, and skid plate—are engineered to provide structural rigidity whilst protecting internal components from dirt, moisture, and impact during challenging terrain work. The motor plate interface ensures precise motor alignment for optimal power transmission. This is not a budget transmission; it is genuine OEM Axial engineering designed for reliability and performance in the hands of serious RC enthusiasts who demand durability and precision from their rock crawling equipment.

Frequently Asked Questions
- Is this SCX30 transmission compatible with my Axial rock crawler? — This transmission is specifically designed for the Axial 1/30 SCX30 series and is confirmed compatible with the Ford Bronco 4X4 RTR (blue and grey variants), Chevrolet K10 4x4 RTR (black and green variants), and Jeep Wrangler JLU 4X4 RTR (green and white variants). Check your vehicle model number against these compatibilities to ensure proper fit.
- Do I need to assemble this transmission? — No, this is a fully assembled transmission unit that arrives ready to install. All internal components, gears, bearings, and fasteners are pre-assembled and tested, eliminating the need for time-consuming component assembly and reducing potential fitment issues.
- What makes a worm gear transmission better for rock crawling? — Worm gear transmissions provide excellent low-speed torque control and precise throttle response, which are essential characteristics for technical rock crawling where vehicles need to negotiate obstacles slowly and deliberately. The gear arrangement creates natural mechanical advantage that helps deliver power consistently across varying terrain.
- What is the difference between this transmission and other aftermarket options? — As a genuine OEM Axial part, this transmission is manufactured to exact factory specifications using original materials and tolerances. The precision engineering, quality ball bearings, and professional-grade Mod 0.3 gears ensure reliability and performance that matches the original equipment standard. This is not a clone or third-party reproduction—it's the authentic component.
- Will this transmission work as a direct replacement? — Yes, as a genuine OEM part manufactured by Axial, this transmission is engineered as a direct replacement for damaged or worn transmissions in compatible SCX30 vehicles. Simply remove your existing transmission and install this unit using the included fasteners.
- Is this suitable for beginners working on their first repair? — Whilst this is a pre-assembled unit that eliminates complex internal assembly, transmission installation does require mechanical competence and appropriate tools. If you're new to RC maintenance, we recommend consulting your vehicle's instruction manual or seeking guidance from experienced RC enthusiasts at RC Model Shop before beginning work.
