The bottom shaft is a critical component in this transmission assembly, directly affecting power delivery, gear engagement, and overall drivetrain efficiency.
RC enthusiasts and weekend bashers alike recognise the importance of using genuine, quality replacement parts to keep their vehicles running at peak performance. The AXIAL 2-Speed Hi Lo Transmission Bottom Shaft is precision-engineered to ensure perfect fitment and seamless operation within your transmission system, giving you confidence that your RC crawler or truck will perform reliably on every outing.
Key Features
- 2-Speed Bottom Shaft Assembly — This component is the core of your transmission's bottom shaft, designed to work seamlessly with Axial's 2-speed hi-lo transmission system to deliver smooth gear transitions and consistent power delivery across both high and low speed ranges.
- Steel Construction for Durability — The shaft is manufactured from high-quality steel, which provides exceptional strength and resistance to the stresses and impacts encountered during rock crawling, off-roading, and general RC use, ensuring long service life even under demanding conditions.
- Black Oxide Coating to Resist Corrosion — The protective black oxide coating applied to the steel surface provides a significant advantage by preventing rust and corrosion, particularly important for RC vehicles used in wet conditions or stored in damp environments, extending the lifespan of this crucial drivetrain component.
- Genuine Axial Product — As an official Axial spare part, this bottom shaft is manufactured to the exact same specifications and quality standards as the original component fitted to new vehicles, guaranteeing compatibility and performance without compromise.
- Perfect Fitment for SCX10 II Models — This component is confirmed to fit the AXIC9046 1/10 SCX10 II Jeep Cherokee 4WD Rock Crawler Kit and the AXI90075 1/10 SCX10 II UMG10 4WD Rock Crawler Kit, as well as other compatible Axial 2-speed transmission equipped vehicles.
Technical Performance
The AXIAL 2-Speed Hi Lo Transmission Bottom Shaft 5x76.5m represents precision engineering at its finest, designed to function as a critical component within Axial's renowned 2-speed transmission system. The shaft features a nominal diameter of 5mm and a length of 76.5mm, providing the exact dimensions required for proper fitment and alignment within your transmission case. Steel construction delivers the hardness and tensile strength necessary to handle the forces generated during rock crawling, when obstacles place extreme loads on the drivetrain. The black oxide coating applied during manufacturing creates a thin, protective layer that resists corrosion from moisture, salt spray, and the general wear that comes from regular use in outdoor environments. This component works in concert with other transmission elements to manage power delivery from your motor to the wheels, allowing drivers to select between high gear for cruising and low gear for technical crawling where maximum torque and low-speed control are essential. For RC car enthusiasts in the UK seeking reliable, genuine replacement parts that maintain the performance characteristics of their original equipment, this bottom shaft delivers the quality assurance and compatibility that matters.

Frequently Asked Questions
- What is the AXIAL 2-Speed Hi Lo Transmission Bottom Shaft and what does it do? — The bottom shaft is a critical drivetrain component within Axial's 2-speed hi-lo transmission system. It connects the transmission gears and transfers power from the motor to the driveshafts, allowing the transmission to select between high speed and low speed (high torque) ratios. Without a properly functioning bottom shaft, your transmission cannot operate correctly.
- Which RC models is this bottom shaft compatible with? — This component is designed for Axial vehicles equipped with the 2-speed hi-lo transmission system, including the AXIC9046 1/10 SCX10 II Jeep Cherokee 4WD Rock Crawler Kit and the AXI90075 1/10 SCX10 II UMG10 4WD Rock Crawler Kit, along with other compatible Axial models featuring the same transmission architecture.
- Is this a genuine Axial part or an aftermarket clone? — This is a genuine, official Axial product manufactured to exact OEM specifications. It carries the authorised Axial part number Z-AX31413 and is identical to the component supplied with new Axial vehicles, ensuring perfect compatibility and reliable performance.
- Why would I need to replace the bottom shaft? — The transmission bottom shaft can wear, strip threads, or suffer damage from impacts during rock crawling or off-roading. If your transmission becomes difficult to shift between gears, makes grinding noises, or fails to engage properly, a damaged bottom shaft may be the cause, and replacement restores full functionality.
- What is the black oxide coating and why does it matter? — Black oxide is a protective surface treatment applied to steel components to prevent rust and corrosion. For an RC component like this shaft that is exposed to moisture, dirt, and the general environment during outdoor use, the black oxide coating extends the lifespan by protecting the underlying steel from oxidation.
- Will this fit other RC transmission systems? — No, this bottom shaft is specifically engineered for Axial's 2-speed hi-lo transmission system and is not compatible with other transmission designs or manufacturers' vehicles. Always verify compatibility with your specific model before ordering replacement parts for your RC car.
- Is this suitable for beginners? — This is a replacement part designed for users who already own an Axial 2-speed transmission equipped vehicle and need to perform maintenance or repair. It is not a standalone product for beginners just starting in RC, but rather a component for existing owners who understand their vehicle's drivetrain.
