Traxxas Rear Steel Constant-Velocity Driveshaft 2pcs TRX9654X

Overview

Upgrade your Traxxas Sledge with the ultimate driveline enhancement: the Traxxas Rear Steel Constant-Velocity Driveshaft (2 pcs) TRX9654X. Whether you're a serious RC enthusiast in the UK looking to maximise performance, a weekend basher pushing your brushless monster truck to its limits, or someone seeking to extend the lifespan of critical drivetrain components, these heavy-duty rear CV driveshafts represent a significant step up from standard equipment. Engineered from hardened steel and built to Traxxas's exacting standards, these complete assembly driveshafts deliver the ultimate in torque handling and efficient power transfer, making them an essential upgrade for the most demanding drivers who refuse to compromise on quality or durability.

The Sledge is already a formidable 1/8 scale brushless electric monster truck, but its performance ceiling can be dramatically elevated with the right upgrades. These steel constant-velocity driveshafts address one of the critical weak points in high-performance RC vehicles: power transmission under extreme stress. Standard driveshafts can flex, slip and fail under the intense torque loads generated by brushless motors and LiPo batteries, leading to lost power, inconsistent handling and costly repairs. By upgrading to these steel CV driveshafts, you'll experience significantly improved power transfer directly to the wheels, sharper acceleration response, and the peace of mind that comes from knowing your drivetrain can handle whatever punishment you throw at it.

Ready to run RC setups like the Sledge are designed for performance, but truly competitive driving and extended bashing sessions demand these kinds of transmission upgrades. The Traxxas TRX9654X driveshafts come complete and ready to install, requiring no additional assembly or modification, making the upgrade process straightforward even for those new to RC car customisation in the UK.

Key Features

• Hardened Steel Construction — These driveshafts are machined from premium hardened steel rather than softer materials, which means they can withstand significantly higher torque loads without deformation or failure. This is particularly important when running high-powered brushless motors that generate torque spikes during acceleration and when navigating rough terrain.
• Constant-Velocity Joint Design — The CV joint technology ensures smooth, consistent power delivery at any suspension angle, eliminating the binding and jerking that can occur with standard universal joints. This results in more predictable handling, smoother acceleration and better traction in all driving conditions.
• Larger 6mm Stub Axle — The driveshafts feature a larger diameter 6mm stub axle, which provides greater surface area for load distribution and reduces stress concentration. This larger diameter means reduced wear on the differential output cups and longer service life for your entire drivetrain.
• Sealed and Lubricated U-Joints — The outer U-joints are completely enclosed by protective rubber boots and come pre-lubricated from the factory. This dual protection system keeps dirt, water and debris out of the critical joint areas whilst maintaining proper lubrication for smooth operation, which is essential for UK weather conditions where moisture and contamination are constant challenges.
• Captive U-Joint Pins — The U-joint pins are held captive by the joint design, meaning you'll never have to worry about losing pins during a crash or heavy use. This design feature saves frustration and costly downtime when you're out bashing with your RC truck.
• Nickel-Plated Finish — The shafts feature an attractive gleaming nickel-plated surface that not only looks premium but also provides corrosion resistance. This protective coating is particularly valuable if you're running your RC car in wet UK conditions or near coastal areas where salt spray can cause rapid deterioration.
• Black Silicone Boots — The protective rubber boots are finished in black silicone, which complements the nickel plating for a custom, professional appearance whilst providing superior protection against the elements compared to standard rubber compounds.
• Ambidextrous Design — Each driveshaft assembly works in either the left or right position, giving you complete flexibility in your setup and making these truly universal rear driveshaft upgrades for your Sledge.
• Complete Assembly Ready to Install — The driveshafts come as complete assemblies requiring no further construction or assembly. Simply remove your standard driveshafts and install these directly onto either your standard 9583 rear differential output cups or the optional 9583X hardened steel output cups for maximum durability and performance.
• Two Pairs Included — You receive two complete driveshaft assemblies in this package, providing both rear driveshafts needed for a complete rear axle upgrade on your Sledge.

Technical Performance

These steel constant-velocity driveshafts represent a quantum leap in drivetrain engineering for the Traxxas Sledge platform. The hardened steel construction directly addresses the limitations of softer materials, which can flex under load and lose efficiency. The constant-velocity joint design is crucial for modern RC trucks because it maintains equal angular velocity throughout the range of motion, preventing the binding and power loss that occurs with traditional universal joints, particularly when the suspension is fully compressed or extended during aggressive driving. The 6mm stub axle diameter is a significant specification as it directly increases the load-carrying capacity and reduces stress concentration in the most critical connection points. The sealed, lubricated outer U-joints with captive pins represent factory-quality engineering that eliminates maintenance headaches and potential failure points in the field. These are the driveshafts chosen by Traxxas engineers themselves for maximum performance and longevity, and they are specifically designed to work seamlessly with the Sledge's brushless drivetrain, which generates substantially more torque than nitro or brushed electric motors. Whether you're running a 3S or 4S LiPo battery setup, these driveshafts will reliably transmit the power to the wheels without slippage or mechanical compromise.
