If you're searching for upgrade parts for your RC car UK or looking to maximise performance on your brushless RC short course truck, these front driveshafts are an essential investment in your vehicle's drivetrain durability.

Traxxas has engineered these extreme heavy-duty steel splined driveshafts specifically to handle the brutal demands of high-performance RC driving. Designed with the same Traxxas-Tough™ engineering philosophy that powers their most demanding models, these components are built to withstand the massive torque outputs of modern brushless RC vehicles. The unique splined telescoping design delivers full-range articulation, meaning you never need to limit suspension travel to protect your driveshafts, a feature that truly sets them apart from ordinary metal shaft alternatives available for ready to run RC cars.

Perfect for anyone serious about RC car performance in the UK market, whether you're weekend bashing at full throttle or putting your RC vehicle through its paces on challenging terrain, these front steel CV driveshafts offer the peace of mind and performance reliability that separates quality upgrades from basic components. The package includes two complete front driveshafts, giving you everything needed to upgrade your vehicle's front end.

Key Features

• Heavy-Duty Steel Splined Design — These driveshafts are constructed from premium steel with a splined telescoping design that provides maximum articulation without requiring you to limit your vehicle's suspension travel, ensuring optimal handling in all driving conditions.
• Constant-Velocity (CV) Joints — The CV joints ensure smooth, efficient power transfer from your motor to the wheels across the full range of suspension movement, delivering consistent torque delivery whether your suspension is compressed or fully extended.
• Large 10mm CV Balls — These oversized CV balls provide significantly greater load-carrying capacity and durability compared to standard shaft designs, making them ideal for high-power brushless RC vehicles and extreme driving conditions.
• Metal Pin-Retention Rings — Drive pins are secured in place with metal pin-retention rings, providing extra security during high RPM speed runs and preventing pin loss that could otherwise damage your driveshafts or suspension components.
• Lubricated and Sealed U-Joints — The outer U-joints are fully lubricated and sealed with a protective rubber boot, keeping contaminants out and maintaining optimal joint performance even in muddy, wet, or dusty RC driving environments.
• Captive U-Joint Pins — U-joint pins are held captive by design, meaning you never have to worry about losing a pin during operation or maintenance, eliminating potential drivetrain damage and downtime.
• Premium Nickel-Plated Finish — The gleaming nickel-plated shafts provide both exceptional corrosion resistance and an impressive custom appearance that enhances your RC vehicle's aesthetics.
• Black Silicone Boots — High-quality black silicone boots complement the nickel-plated finish for a professional custom look while providing superior protection against water, dirt, and debris.
• Perfect Fit and Easy Installation — Being manufactured by Traxxas specifically for compatible models ensures perfect fit and straightforward installation without modification or adjustment required.
• Fits Multiple 4WD Models — These front steel CV driveshafts are compatible with Slash 4x4, Stampede 4x4, Rustler 4x4, and Ford Fiesta ST Rally RC vehicles, making them a versatile upgrade option for multiple platforms.

Technical Performance

These Traxxas front steel CV driveshafts represent the pinnacle of RC drivetrain engineering for 1/10 scale 4WD vehicles. Constructed from premium hardened steel with precision-splined connections, they are specifically engineered to handle the extreme torque outputs of modern brushless RC motors, including those found in high-powered VXL variants. The constant-velocity joint design eliminates the binding and loss of efficiency that occurs with traditional universal joints when operating at extreme suspension angles, ensuring that every watt of power from your brushless motor is transmitted efficiently to the wheels. The 10mm CV balls are substantially larger than those found on standard driveshafts, providing significantly greater surface area for load distribution and reducing stress concentrations that lead to premature failure. The splined telescoping design is a Traxxas innovation that allows full suspension articulation without requiring you to compromise on driveshaft length or strength—your suspension can move through its complete range of travel without binding or forcing you to use shorter, stiffer suspension geometry. Metal pin-retention rings ensure that drive pins remain securely in place even during aggressive acceleration runs or when navigating technical terrain, preventing the catastrophic pin loss that can occur with lesser quality designs. The sealed and lubricated outer U-joints are protected by durable rubber boots that shield them from water, mud, and grime, maintaining smooth operation and extending component life. Whether you're running a 4S LiPo-powered brushless RC short course truck or pushing a rally car to its limits, these driveshafts deliver the reliability and performance demanded by serious RC enthusiasts across the UK.

Frequently Asked Questions

• What RC models are these front steel CV driveshafts compatible with? — These Traxxas front steel CV driveshafts (TRX6851R) are specifically designed for 1/10 scale Traxxas 4x4 vehicles including the Slash 4x4, Stampede 4x4, Rustler 4x4, and Rustler Ultimate VXL 4x4, as well as the Ford Fiesta ST Rally, Ford Fiesta ST Rally VXL, and Ford Fiesta ST Rally BL-2S Rally Car. They are precision-engineered for perfect fit and optimal performance on these platforms.
• Are these driveshafts suitable for upgrading a standard RC car? — Yes, absolutely. If you own any of the compatible 4x4 models and are looking to upgrade from stock driveshafts to heavy-duty steel CV components, these represent a significant upgrade in durability and torque handling capacity. They are ideal for bashers and racers who run high-powered brushless motors and want to eliminate drivetrain failures.
• What makes these different from standard metal driveshafts? — Traxxas' unique splined telescoping design with 10mm CV balls and metal pin-retention rings delivers superior articulation and durability compared to ordinary metal shafts. Standard driveshafts often force you to limit suspension travel to prevent binding, whereas these allow full-range articulation. The oversized CV balls and metal pin-retention rings also provide significantly greater load capacity and security during high-speed runs.
• Will these driveshafts handle 4S LiPo power? — Yes, these heavy-duty steel CV driveshafts are specifically engineered to handle the extreme torque outputs of brushless motors powered by high-voltage LiPo batteries. They are tested and proven on Traxxas' most powerful VXL brushless systems, making them ideal for maximum-power RC driving.
• Do these require any special installation or modification? — No, these are plug-and-play replacements designed by Traxxas for perfect fit on compatible models. Easy installation is a hallmark of Traxxas engineering, so you can swap out your old driveshafts and get back to driving quickly without any modification required.
• How long will these driveshafts last? — The heavy-duty steel construction, sealed lubricated joints, and captive pin design are all engineered for maximum longevity. Lifespan depends on driving conditions and power levels, but these are designed to outlast standard driveshafts by a significant margin, particularly when used on high-power brushless RC vehicles.
• Can I use these on a 2WD model? — No, these are specifically engineered for 4WD models. Traxxas offers different driveshaft designs optimised for their various platforms, so it's important to ensure you select front driveshafts compatible with your specific 4WD model.
