Traxxas Sledge Rear Centre Driveshaft Shaft Only 4mm x 146.5mm TRX9556

Overview

The Traxxas Driveshaft, Centre, Rear (shaft only, 4mm x 146.5mm) (1pc) TRX9556 is an essential drivetrain component designed for the Traxxas Sledge Belted 1:8 4WD Brushless Electric Monster Truck. This centre driveshaft is a critical spare part for RC enthusiasts in the UK who demand reliable performance from their high-performance RC monster trucks. Whether you're a weekend basher pushing your Sledge to its limits or a serious RC hobbyist maintaining your fleet, having quality spare driveshafts on hand ensures your RC vehicle remains in peak operating condition without interruption.

The centre rear driveshaft plays a vital role in the drivetrain system, transferring power from the transmission to the rear axle assembly. For owners of the Traxxas Sledge 1:8 scale brushless RC monster truck, this component is subject to significant stress during aggressive driving, jumping and high-speed runs. The TRX9556 is the genuine Traxxas replacement part that ensures compatibility and reliability. UK RC enthusiasts and competitors rely on authentic Traxxas spare parts to maintain their vehicles at the highest standards, and this centre driveshaft is no exception. Whether you're upgrading worn components or building up a replacement drivetrain assembly, this shaft-only configuration allows you to customise your setup precisely.

RC Model Shop stocks the complete range of genuine Traxxas spare parts for the Sledge and other brushless RC vehicles. This particular driveshaft is engineered to withstand the demands of 1/8 scale brushless electric power, making it ideal for anyone serious about their RC car UK hobby. With proper maintenance and quality spare parts, your Traxxas Sledge will continue to deliver the extreme performance and durability that the Traxxas brand is recognised for worldwide.

Key Features

• Genuine Traxxas OEM Component — This is an authentic original equipment manufacturer part directly from Traxxas, ensuring perfect compatibility with your Sledge 1:8 monster truck and meeting the exact engineering specifications required for reliable drivetrain operation.
• Centre Rear Position Design — Specifically engineered for the centre rear driveshaft location on the Sledge, this component is optimised for the load requirements and positioning of the rear differential output, ensuring smooth power transmission without binding or vibration.
• 4mm Diameter Shaft — The 4mm shaft diameter is the standard specification for Sledge drivetrain compatibility, providing the correct fit for your differential output splines and rear axle carrier bearings without requiring modifications.
• 146.5mm Total Length — The precisely engineered 146.5mm length is critical for proper spacing between the differential and rear axle assembly, ensuring correct suspension geometry and preventing driveline angle issues that could affect handling and component longevity.
• Shaft Only Configuration — Supplied as the shaft component only, this design allows experienced RC builders and those with existing CV joints to replace just the shaft element, reducing costs and waste if your existing joints are still serviceable.
• Heavy-Duty Construction — Built to withstand the stresses of 1:8 scale brushless electric power delivery, including high-speed acceleration, jumping impacts, and aggressive cornering loads typical of modern RC monster truck driving.
• Direct Replacement Part — This TRX9556 driveshaft is the direct OEM replacement for worn, bent or damaged centre rear driveshafts, ensuring you can restore your Sledge to factory specifications quickly and reliably.

Technical Performance

The Traxxas Driveshaft Centre, Rear (TRX9556) represents precision engineering designed specifically for 1:8 scale brushless electric RC monster trucks like the Sledge Belted. The 4mm shaft diameter and 146.5mm length have been engineered by Traxxas to provide optimal performance in the rear drivetrain configuration, where substantial torque loads are concentrated during acceleration and climbing. The centre driveshaft position is critical to the overall drivetrain geometry and performance envelope, sitting between the transmission output and the rear axle differential. With the brushless power systems used in modern Traxxas vehicles — delivering consistent, high-torque performance across the RPM range — quality driveshaft components are essential to reliability. The shaft-only configuration allows builders flexibility in their setup, whether they're performing maintenance, replacing damaged components, or customising their drivetrain assembly. For UK RC enthusiasts running the Sledge monster truck at high speeds or in competitive bashing environments, maintaining original Traxxas specification driveshafts ensures your vehicle continues to perform at peak capability without compatibility concerns or performance compromises.

Frequently Asked Questions

• What Traxxas model does the TRX9556 driveshaft fit? — The TRX9556 is specifically designed for the Traxxas Sledge Belted 1:8 4WD Brushless Electric Monster Truck, available in all colour variants including blue, orange, green, and red. It serves as the centre rear driveshaft component in the rear drivetrain assembly.
• Is this a complete driveshaft replacement or just a shaft? — This product is a shaft-only component, meaning it includes just the driveshaft shaft element without CV joints, U-joints or universal coupling components. If you need a complete assembly with joints included, you may need to check with Traxxas for fully assembled driveshaft options, but this shaft-only format is ideal for replacing just the shaft if your existing joints are still in good condition.
• Why would I need to replace my centre driveshaft? — Driveshafts can wear out, bend, or damage through normal use, aggressive driving, jumping impacts, or collision damage. Regular maintenance and inspection of drivetrain components is recommended for any serious RC enthusiast. Keeping spare driveshafts on hand means you can quickly return your Sledge to action without waiting for repairs.
• Is this suitable for high-speed brushless RC driving? — Yes, absolutely. The TRX9556 is engineered specifically for the high-performance brushless power systems used in the Sledge 1:8 monster truck, which can achieve significant speeds and deliver consistent torque. The centre driveshaft must handle considerable drivetrain loads during acceleration, braking and extreme driving conditions, and the genuine Traxxas component is designed precisely for this purpose.
• What is the difference between the centre, front and rear driveshafts? — In 4WD systems like the Sledge, different driveshafts are positioned in different locations — front, centre and rear — each optimised for the specific load paths and angles at their position. The TRX9556 is specifically the centre rear position shaft, engineered for that particular location's requirements. Using the correct shaft for each location ensures proper fit, geometry and performance.
• Do I need any special tools to install this driveshaft? — Installation will depend on your specific setup and existing components. You'll need to remove the old shaft and install the new one in the same position. Some basic RC tools like hex drivers may be required, along with potentially some light grease for assembly. It's recommended to consult your Sledge manual or Traxxas technical resources for detailed installation instructions specific to your vehicle.
• Can I use this driveshaft on other Traxxas models? — The TRX9556 is specifically engineered for the Sledge and may not be compatible with other Traxxas models due to differences in drivetrain geometry, shaft diameter, length and connection methods. Always verify compatibility with your specific vehicle model before purchasing spare parts.
