Key Features

• Steel Constant-Velocity Design — Steel CV construction offers superior torque handling and efficient power transfer compared to plastic alternatives, ensuring your brushless motor's power reaches the wheels without loss or flex, even under extreme acceleration and load.
• Splined Telescoping Technology — Traxxas' unique splined telescoping design delivers full-range articulation without limiting suspension travel, meaning your suspension can compress and extend fully while maintaining perfect driveline engagement.
• Precision Drive Pin Engineering — Large-bore drive pins are press-fit on the differential side and slot into heavy-duty steel drive cups, providing a robust mechanical connection that resists backlash and wear during high-powered brushless driving.
• Bearing-Secured Drive Pins — On the axle side, bearings securely lock the drive pins in place to prevent back-out, eliminating the risk of catastrophic drivetrain failure during aggressive cornering or sudden acceleration.
• Rubber-Sealed Bearings — The included rubber-sealed bearings keep out dirt and debris, extending the service life of your driveshaft and ensuring consistent performance in dusty or muddy RC driving environments across the UK.
• Black-Oxide Rust Protection — A durable black-oxide coating helps prevent rust on the drive gear, ensuring your driveshaft resists corrosion even when exposed to moisture or stored in damp conditions.
• 63.5mm Shaft Length — Precisely sized for the 10790 WideMaxx suspension kit, this shaft length ensures proper geometry and optimal weight distribution for balanced handling and acceleration.
• Genuine Traxxas Component — As an authorised Traxxas replacement part, this driveshaft meets exact OEM specifications and is guaranteed to fit perfectly with WideMaxx suspension systems.

Technical Performance

This steel CV driveshaft represents the pinnacle of RC drivetrain engineering, engineered specifically for high-performance brushless applications where torque and reliability are non-negotiable. The steel construction, combined with Traxxas' proven constant-velocity design, ensures maximum power transfer efficiency from your brushless motor to the wheels. The large-bore press-fit drive pins and heavy-duty steel drive cups create a rigid mechanical interface that eliminates flex and backlash, critical for consistent acceleration and precise handling. The bearing-secured design prevents pin back-out under extreme torque loads, whilst the splined telescoping mechanism allows unlimited suspension articulation without compromising driveline integrity. The rubber-sealed bearings provide long-term durability in challenging UK driving conditions, from dusty off-road tracks to wet grass fields, whilst the black-oxide coating protects against corrosion. At 63.5mm in length, this shaft is precisely calibrated for WideMaxx suspension geometry, ensuring proper suspension kinematics and optimal weight distribution. Whether you're pushing a high-KV brushless motor or running demanding 8S LiPo power, this steel driveshaft delivers the torque handling and efficiency that serious RC car drivers demand.

Frequently Asked Questions

• Which Traxxas models does this driveshaft fit? — This driveshaft is specifically designed for use with the Traxxas 10790 Mini Maxx WideMaxx suspension kit. It is a replacement component for the steel CV driveshaft set and is compatible with Traxxas Funco Motorsports Pro Scale 8S 2WD Electric Sand Car models in all colour variants (Orange, Green, Red, Blue).
• Why should I choose steel CV driveshafts over plastic alternatives? — Steel constant-velocity driveshafts offer superior torque handling and more efficient power transfer, particularly crucial for high-power brushless RC applications. The steel construction resists flex and maintains precise geometry under extreme acceleration, ensuring reliable power delivery and extended service life compared to plastic alternatives.
• What is the splined telescoping design and why does it matter? — Traxxas' splined telescoping mechanism allows the driveshaft to compress and extend smoothly as your suspension articulates, delivering full-range articulation without limiting suspension travel. This means you can run maximum suspension geometry without needing to compromise ride height or handling characteristics.
• What are the bearing-secured drive pins and why are they important? — The drive pins connect the driveshaft to your suspension and wheels. Traxxas secures these pins with bearings on the axle side to prevent them from backing out, eliminating the risk of sudden drivetrain failure during aggressive driving or high-torque situations.
• Is this a complete driveshaft assembly or a shaft only? — This is a shaft-only component, meaning you receive the driveshaft with pre-assembled bearings and drive pins. It is designed as a direct replacement for the 10790 WideMaxx steel CV driveshaft set.
• What wheel hub and nut specifications do I need? — This driveshaft requires 8654-series 17mm splined wheel hubs and 7758-series 17mm wheel nuts for proper fitment. These are Traxxas genuine components designed to work with this driveshaft's spline pattern.
• How does the black-oxide coating protect my driveshaft? — Black-oxide is a protective chemical coating that prevents rust and corrosion on steel components. This is particularly valuable for RC enthusiasts in the UK who drive in wet conditions, as it extends the service life of the drive gear and maintains smooth operation.
• Can I use this driveshaft with narrow Maxx suspension? — No, this driveshaft is specifically engineered for WideMaxx suspension geometry. The 63.5mm length and spline profile are optimised for the wider Maxx suspension kit, not the narrow V.1 variant.
• How often should I service or replace this driveshaft? — With proper maintenance including regular bearing inspection and cleaning after muddy drives, this steel CV driveshaft is extremely durable. Replace only if you experience visible damage, bearing wear, or loss of smooth operation. The rubber-sealed bearings should keep dirt out during normal use.
• Is this compatible with high-powered 8S brushless systems? — Yes, the steel construction and heavy-duty drive pins are specifically engineered for high-torque brushless applications. This driveshaft is ideal for users running powerful brushless motors in their Traxxas vehicles.
