Technical Performance
The AXIAL Straight Axle 6x104 50mm represents precision drivetrain engineering designed for the demands of modern RC adventuring. Built from durable materials engineered to withstand the punishment of aggressive driving across challenging terrain, these axles are manufactured using Axial's rigorous quality control standards. The 6x104mm specification indicates a shaft diameter of 6mm with a 104mm spline pattern, providing maximum engagement surface area and minimising the risk of slippage under load. At 50mm in length, these axles are engineered for specific suspension geometries and differential spacings found in Axial's most popular models. Whether you're running a ready to run RC vehicle fresh from the box or a custom-built competition crawler, these OEM axles ensure that power is delivered smoothly and consistently from your motor to the wheels. The straight design (as opposed to CVD or universal joint variations) provides a simple, lightweight solution for applications where those additional features aren't required, making these ideal replacement components or upgrade options for builders looking to optimise their drivetrain configuration. For UK RC enthusiasts who take their vehicles seriously, maintaining a supply of quality OEM axles is essential for keeping your machine running at peak performance and minimising frustration from mechanical failures.

Frequently Asked Questions
- What vehicles are these AXIAL straight axles compatible with? — These axles are Axial OEM components designed for specific Axial models. The 6x104 50mm configuration is found in a range of Axial crawlers and adventure vehicles. Always check your vehicle's manual or parts diagram to confirm compatibility with your specific model before ordering, or contact our team at RC Model Shop for guidance on which Axial vehicles these axles will fit.
- Are these suitable for beginners just starting with RC cars? — Whilst these axles are not the type of component beginners typically need immediately, any RC enthusiast who progresses beyond basic ready to run operation should familiarise themselves with drivetrain maintenance and understand the importance of quality replacement parts. Having spare axles available demonstrates the kind of forward planning that separates casual players from committed hobbyists.
- How long do RC axles typically last before replacement is needed? — With normal use on a ready to run RC vehicle, axles can last many hours of operation. However, aggressive driving across rough terrain, high-speed impacts, or repeated crashes can accelerate wear or cause breakage. Carrying spares ensures you're never stranded during a driving session and can quickly repair damage and get back into action.
- What's the difference between straight axles and CVD axles? — Straight axles like these provide a simple, lightweight connection point and are ideal for lower-speed technical driving where articulation and suspension flex are carefully controlled. CVD (Constant Velocity) axles include additional joints and are designed for higher-speed applications with more aggressive suspension movement. Axial offers both options to suit different driving styles and terrain types.
- How do I know if my axles need replacement? — Signs of axle wear include grinding noises from the drivetrain, difficulty engaging gears, or visible bending or cracks. If your vehicle jumps out of gear or won't drive smoothly, damaged axles are often the culprit. Our experienced team at RC Model Shop can help diagnose drivetrain issues if you're unsure whether replacement is needed.
