Key Features

• Genuine HOBAO Component — As an official HOBAO part, this CVD shaft meets the manufacturer's exacting quality standards and is engineered to work seamlessly with your SST EP truggy, ensuring reliable power transmission and consistent performance in racing or recreational driving conditions.
• +2mm Extension Specification — The +2mm offset provides enhanced geometric clearance and improved suspension travel characteristics, particularly beneficial for custom build configurations or those running specific ride height adjustments that require extended drivetrain geometry.
• 4.5mm Diameter Shaft — The 4.5mm shaft diameter is the standard specification for the SST EP platform, ensuring perfect compatibility with your existing gearbox output and wheel hub components without modification or adapter requirements.
• 141mm Total Length — This dimension specifies the complete length of the assembled CVD shaft, providing the correct geometry for proper suspension articulation and consistent handling across varied terrain and driving conditions.
• Pair of Two Shafts — This package includes two CVD shafts, making it suitable for replacing both front and rear axles or providing a complete spare set, which is particularly valuable for competitive drivers or those who run multiple vehicles.
• Constant Velocity Design — CVD shafts with constant velocity joints deliver smooth, efficient power transmission throughout the full range of suspension movement, minimising drivetrain binding and improving traction and handling consistency during cornering and jumps.
• Precision Engineering — HOBAO's manufacturing expertise ensures tight tolerances and perfect balance, reducing vibration and extending the operational life of associated drivetrain components including gearbox bearings and wheel hubs.

Technical Performance

The HOBAO CVD Shaft represents the pinnacle of precision engineering for 1/8 scale electric RC car drivetrain systems. Manufactured from high-quality materials selected for their strength-to-weight ratio and durability under the extreme forces generated by brushless motors and high-performance ESCs, these shafts are designed to handle the demands of competitive racing and aggressive recreational driving. The 4.5mm diameter specification is perfectly calibrated for the SST EP platform, providing optimal clearance within the gearbox housing whilst maintaining structural rigidity to prevent flexing under load. The constant velocity joint design ensures that power is transmitted smoothly even when the suspension is fully compressed or extended, a critical factor in maintaining consistent traction when launching hard off the line or navigating challenging terrain. The +2mm extension geometry offers flexibility for builders seeking specific ride height or suspension travel characteristics, allowing customisation of the truck's handling balance and ground clearance. The 141mm total length is precisely engineered to integrate seamlessly with the SST EP's suspension geometry, ensuring proper differential geometry and consistent handling response. For UK RC car enthusiasts running their SST EP in competitive events or challenging driving scenarios, maintaining quality drivetrain components like these CVD shafts is essential for reliability and performance consistency. The pair configuration means you're getting both front and rear shafts, or a complete spare set if maintaining a competition vehicle.

Frequently Asked Questions

• What is a CVD shaft and why does my HOBAO SST EP need one? — A CVD (Constant Velocity) shaft is a crucial drivetrain component that transfers power from your truck's gearbox to the wheels whilst accommodating suspension movement. The CVD joint technology ensures smooth power delivery throughout the full range of suspension articulation, preventing drivetrain binding and vibration that would otherwise occur with simpler designs. The SST EP relies on quality CVD shafts for optimal performance, and this genuine HOBAO component is engineered specifically for your vehicle's geometry and requirements.
• Why is the +2mm specification important? — The +2mm extension modifies the geometric relationship between the gearbox and wheel hub, providing additional clearance that can improve suspension travel and alter handling characteristics. This is particularly valuable for custom builds, specific ride height configurations, or those optimising their setup for particular driving styles or track conditions. If you're unsure whether +2mm is correct for your current setup, we recommend consulting your vehicle's manual or contacting our expert team for guidance.
• How often should I replace my CVD shafts? — Quality CVD shafts like these HOBAO components can last a considerable time with proper maintenance, but they should be inspected regularly for signs of wear, damage, or joint degradation. If you notice vibration, unusual sounds from the drivetrain, or visible damage to the shafts, replacement is recommended immediately. Competitive drivers often maintain spare sets for reliability at events, whilst recreational users may only need replacements as wear demands.
• Are these shafts compatible with other HOBAO models? — These CVD shafts are specifically engineered for the HOBAO SST EP 1/8 scale electric truggy. Whilst other HOBAO vehicles may use similar components, specifications can vary slightly. Always verify compatibility with your specific model before purchasing to ensure perfect fit and performance. If you're uncertain, our experienced RC specialists at RC Model Shop can help you identify the correct component for your vehicle.
• Can I upgrade my standard shafts to these +2mm versions? — Yes, upgrading from standard geometry to the +2mm specification is possible and can improve suspension travel and handling balance in many setups. However, this geometric change will affect your vehicle's ride height, differential geometry, and overall handling characteristics. We recommend making the upgrade as a complete front and rear pair to maintain balanced geometry, and testing carefully to ensure the new specification suits your driving style and local track conditions.
