Overview
The Traxxas Driveshafts, Centre Front / 4mm screw pin (1pc) / 3x10 CS (1pc) TRX8556 is an essential replacement and upgrade component for owners of the Traxxas UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck. Whether you're a serious racer pushing your RC car UK to its limits on the track, or a weekend basher enjoying high-speed runs across challenging terrain, driveshaft reliability is absolutely critical to performance and longevity. This genuine Traxxas spare part has been engineered to exact OEM specifications, ensuring perfect compatibility and durability with your UDR platform.
Driveshafts are one of the most heavily stressed components in any high-performance RC vehicle, transferring engine power directly to the wheels through constant rotational force. When you're running an advanced brushless RC setup with serious power delivery, the integrity of your drivetrain becomes non-negotiable. This centre front driveshaft assembly includes everything you need to maintain peak performance: one precision-engineered driveshaft, one 4mm screw pin for secure fastening, and one 3x10 steel cross shaft (CS) bearing component. For dedicated RC enthusiasts in the UK who demand reliability and authenticity, this is the part you need to keep your UDR running at its absolute best.
The inclusion of the 4mm screw pin demonstrates Traxxas's attention to detail in drivetrain design. This small but vital component ensures your driveshaft remains securely connected during the most demanding driving scenarios, preventing detachment during high-acceleration runs or aggressive cornering. Pairing this with the 3x10 cross shaft bearing creates a complete, balanced drivetrain assembly that handles the extreme torque and speed of modern brushless RC racing.
Key Features

When you choose genuine parts, you're investing in reliability and longevity.
- Centre Front Driveshaft Assembly — Specifically engineered for front-axle power delivery on the UDR platform, this driveshaft has been precision-manufactured to handle the extreme torque loads generated by modern brushless motors in 4WD configurations.
- Included 4mm Screw Pin Fastener — The inclusion of one 4mm screw pin means you have the critical fastening component needed for installation, eliminating the need to source additional hardware separately and ensuring you have the exact OEM-spec fastener required.
- 3x10 Cross Shaft Bearing — The integrated 3x10 CS bearing component provides the rotational support needed for smooth, efficient power delivery with minimal friction and wear, contributing directly to faster lap times and extended component lifespan.
- High-Performance Durability — Built from premium materials selected for their resistance to the extreme stresses of competitive RC racing, this driveshaft is engineered to withstand repeated high-torque cycles, aggressive acceleration, and demanding terrain conditions.
- Universal Compatibility with UDR Models — Compatible with both the Traxxas UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck with Fox Racing suspension (TRX85086-4-FOX1) and the Rigid Industries variant (TRX85086-4-RGD1), making this a universal replacement for UDR owners.
Technical Performance
The centre front driveshaft is a critical drivetrain component in any modern 4WD RC short course truck, and the Traxxas UDR represents the pinnacle of pro-scale engineering. This driveshaft assembly must transmit power from the front differential to the wheels whilst simultaneously handling steering inputs during cornering, making its design and materials absolutely paramount. The TRX8556 has been manufactured to exacting tolerances using high-strength materials capable of withstanding the peak torque outputs of brushless RC motor systems. The 4mm screw pin fastener uses a hex-drive head design, allowing for secure fastening with standard hex drivers and preventing accidental loosening during aggressive driving. The 3x10 cross shaft bearing component is precision-engineered to provide minimal rotational resistance whilst maintaining absolute concentricity, critical for balanced wheel speed and optimal handling characteristics. Whether you're running casual bash sessions or competitive race events, this centre front driveshaft maintains the structural integrity and performance consistency that separates the Traxxas UDR from other RC short course trucks available in the UK market. The engineering standard is evident in every detail: precise manufacturing tolerances, premium material selection, and comprehensive testing ensure this component will perform reliably through hundreds of cycles of intense driving.

- What does the 3x10 CS bearing do? — The 3x10 cross shaft bearing (CS) provides rotational support and reduces friction at the driveshaft joints. This bearing enables smooth, efficient power transfer from the motor to the wheels whilst minimising wear and heat generation. It's an essential component for optimal performance and component longevity.
- When should I replace my driveshaft? — You should inspect your driveshaft regularly for signs of damage, cracks, bending, or excessive wear. If you notice vibration, unusual noise, loss of power delivery, or visible damage to the shaft, replacement is recommended. Regular maintenance and inspection extend component lifespan significantly.
- Is this a genuine Traxxas part? — Yes, this is an authentic, authorised Traxxas OEM spare part manufactured to exact factory specifications. When you purchase genuine parts, you ensure perfect compatibility, optimal performance, and the reliability that competitive RC driving demands.
- What is the difference between this centre front driveshaft and other aftermarket options? — Genuine Traxxas parts are manufactured to exact OEM engineering specifications with materials and tolerances selected specifically for the UDR platform.
