Whether you're a dedicated basher pushing your ready-to-run RC truck to its limits or a serious competitor demanding maximum reliability during competitive runs, these steel constant-velocity rear driveshafts deliver the ultimate in torque handling and efficient power transfer. Compatible with a wide range of Traxxas Slash and Stampede 4x4 models, these components are the go-to choice for owners who refuse to compromise on quality or performance.

For RC car enthusiasts in the UK, these driveshafts represent a significant performance investment that transforms how your RC vehicle handles extreme driving conditions. The two-piece complete assembly means everything you need is included in one package, eliminating the frustration of hunting down separate components or compatibility issues. This is the kind of upgrade that seasoned RC hobbyists choose when they want to push their brushless 4WD trucks harder without worrying about mechanical failure.

These aren't just replacement shafts—they're engineered upgrades that showcase Traxxas's commitment to delivering performance parts that backing up their ready-to-run vehicles with genuine aftermarket solutions designed by the manufacturer who knows these machines inside and out.

Key Features

• Steel Constant-Velocity Design — Unlike standard plastic driveshafts, these steel CV shafts offer the ultimate in torque handling and efficient power transfer, meaning more of your brushless motor's power gets delivered directly to the wheels without flex or loss of energy. This is particularly important when running high-powered 4S or 3S LiPo batteries that produce significant torque through the drivetrain.
• Larger 6mm Stub Axle — The increased stub axle diameter provides greater surface area and strength, directly translating to improved durability when experiencing the violent impacts and hard cornering forces that come with aggressive 4WD RC driving. This upgrade is particularly valuable for owners who regularly bash or compete with their Slash Ultimate VXL and similar high-performance 4x4 models.
• Lubricated and Sealed Outer U-Joints — The outer CV joints are factory-lubricated and protected by a sealed rubber boot that creates a barrier against dirt, mud, moisture and the elements. This means your driveshafts maintain their performance even after wet weather driving or dusty track sessions, extending their working lifespan significantly compared to unsealed alternatives.
• Captive U-Joint Pins — The U-joint pins are held captive within the assembly, eliminating the risk of losing critical components during intense driving or after a crash. This is a genuine quality-of-life improvement that means you'll never find yourself stranded at the track or local bash spot hunting for a loose pin in the grass.
• Nickel-Plated Shafts with Black Silicone Boots — Beyond pure function, these driveshafts feature gleaming nickel-plated shafts and black silicone boots that add a custom, professional appearance to your RC vehicle. This aesthetic upgrade reflects the premium engineering inside the assembly and shows that Traxxas understands that RC enthusiasts care about how their vehicles look as much as how they perform.
• Fits Left or Right Position — The universal design means a single part number covers both rear axle positions, simplifying your purchasing and ensuring you have the correct components regardless of which side requires replacement or upgrade.

Technical Performance

These Traxxas steel-spline constant-velocity rear driveshafts represent the pinnacle of drivetrain engineering for 1/10 scale 4WD RC vehicles. The utilisation of steel construction throughout the shaft and CV joint assembly provides substantially greater strength compared to plastic alternatives, handling the extreme torque loads generated by modern brushless RC motors running on high-capacity LiPo batteries. The 6mm stub axle diameter is a significant engineering choice that increases the contact surface area within the differential, distributing forces more effectively and reducing stress concentration points that would otherwise lead to premature failure. The constant-velocity joint design ensures smooth power delivery across a wide range of articulation angles, maintaining efficiency regardless of suspension geometry or driving position. The combination of sealed, lubricated outer U-joints with captive pins creates a maintenance-friendly system that resists contamination from wet conditions and dust whilst eliminating the frustration of lost components. The nickel-plated finish provides both aesthetic appeal and corrosion resistance, ensuring your investment maintains its appearance through countless sessions. These shafts are engineered as a complete assembly, meaning every component is precisely matched from the factory—no mixing and matching required, just drop-in installation confidence.

Frequently Asked Questions

• Are these steel driveshafts compatible with my Traxxas Slash 4x4 RC truck? — Yes, the TRX6852R driveshafts are specifically designed for Traxxas Slash and Stampede 4x4 models. The retailer page lists extensive compatibility with multiple Slash variants including the Slash Ultimate 4x4 VXL, Slash VXL 4x4 RTR, Slash HD XL-5 2WD, Slash Extreme HD VXL 2WD, and standard Slash 2WD models. However, always verify your specific model number matches the listed compatible models before purchasing.
• What makes steel driveshafts better than the plastic ones that came with my RC car? — Steel constant-velocity driveshafts handle significantly more torque and deliver power more efficiently than plastic alternatives. For owners running brushless motors or pushing their RC vehicles hard during bashing or competition, steel shafts resist flex and provide more direct power transfer. The sealed, lubricated CV joints also offer superior weather resistance, meaning your driveshafts function reliably after wet weather driving or dusty sessions that would degrade unsealed plastic components.
• Do I need to maintain these driveshafts? — These are engineered for minimal maintenance. The sealed rubber boots protect the outer U-joints from contamination, and the factory lubrication means you don't need to regularly service them. The captive pins eliminate the possibility of losing components during operation. However, routine inspection after hard driving sessions is always recommended, and replacing the rubber boots if they tear will protect the internal joints.
• What is the difference between these TRX6852R shafts and the standard driveshafts? — The key differences are material construction (steel versus plastic), the larger 6mm stub axle diameter (improved strength and torque handling), sealed outer U-joints (weather protection), captive pins (no lost components), and the nickel-plated custom finish. These upgrades combine to offer superior durability, reliability and efficiency compared to standard equipment, making them essential for serious RC enthusiasts who push their vehicles hard.
• Will upgrading to steel driveshafts improve my RC truck's speed? — Steel driveshafts improve power transfer efficiency, which means more of your motor's power reaches the wheels with less energy loss due to shaft flex. This translates to improved acceleration and overall performance, particularly noticeable when running high-torque brushless motors or pushing hard through technical terrain where standard plastic shafts would flex excessively.
• Can I use these shafts on both 2WD and 4WD Slash models? — These TRX6852R shafts are specifically rear driveshafts compatible with Traxxas Slash and Stampede 4x4 models. The compatibility list includes both 4WD and 2WD Slash variants, but always verify your specific model is listed before purchasing to ensure compatibility.
