Traxxas Centre Driveshafts Front and Rear Assembled 1/18 RC TRX9855

Overview

The Traxxas Driveshafts, Centre, assembled (front & rear) (TRX9855) are premium replacement drivetrain components designed specifically for the TRX-4M High Trail Edition trucks. If you own a 1/18 scale RC crawler with an extended wheelbase, these assembled centre driveshafts are the genuine OEM parts you need to maintain peak performance and reliability. Whether you're a serious RC enthusiast in the UK or a weekend basher who demands quality spares, Traxxas driveshafts represent the gold standard in RC drivetrain engineering.

These driveshafts are not compatible with standard TRX-4M trucks—they are specifically engineered for the High Trail Edition models, including the TRX-4M Chevrolet K10 High Trail Truck and the TRX-4M Ford F-150 High Trail Truck. The extended centre driveshaft design accommodates the longer wheelbase geometry of these vehicles, ensuring proper articulation, smooth power delivery, and maximum durability during aggressive crawling sessions. As an authorised Traxxas dealer, we stock only genuine factory parts that meet Traxxas's strict quality and performance standards.

When shopping for RC car spares online in the UK, you'll find that genuine OEM replacement parts like these driveshafts are essential investments that extend the life of your vehicle and prevent costly damage to other drivetrain components. Unlike cheap aftermarket alternatives, Traxxas driveshafts are engineered to exact tolerances and manufactured using premium materials that withstand the stresses of rock crawling, technical terrain, and constant-velocity turns.

Key Features

• Factory-Assembled Ready-to-Install Design — These driveshafts arrive fully assembled and ready to bolt onto your TRX-4M High Trail truck, eliminating the need for time-consuming assembly or complex installation procedures. This means you can get back on the trails faster and spend more time enjoying your RC crawler rather than working on it.
• Steel Constant-Velocity Construction — The front driveshaft features steel constant-velocity (CV) engineering that provides smooth, efficient power transmission across a wide range of articulation angles. Steel construction ensures superior durability compared to plastic alternatives, making these components ideal for rock crawling terrain where extreme suspension flex is common.
• Extended Centre Driveshaft Design — The extended length of these centre driveshafts is specifically engineered to match the geometry of the TRX-4M High Trail Edition vehicles with their long wheelbase. This ensures proper shaft angles, optimal power delivery, and prevents binding during suspension articulation.
• Genuine Traxxas OEM Quality — As direct factory replacement parts from Traxxas, these driveshafts meet the same stringent engineering specifications and quality standards as the original equipment. You can trust that these parts will perform identically to the factory components your truck left the warehouse with.
• Universal Compatibility Across Multiple Models — These centre driveshafts fit multiple TRX-4M High Trail Edition variants, including the 1979 Chevrolet K10 High Trail Truck in red, black, and blue finishes, and the Ford F-150 High Trail Truck in blue, brown, and black. This makes them a smart spare to keep on hand if you own any of these popular crawlers.
• Enhanced Durability for Technical Terrain — Engineered to withstand the demanding conditions of rock crawling, technical climbing, and obstacle courses, these driveshafts resist the constant stress, torque reversals, and angular deflections that occur during aggressive off-road driving sessions.

Technical Performance

The Traxxas TRX9855 centre driveshafts represent the pinnacle of 1/18 scale RC drivetrain engineering. The front steel constant-velocity driveshaft is manufactured from premium steel that provides exceptional strength-to-weight ratio and consistent performance across a wide operational envelope. Steel offers superior durability compared to plastic or composite alternatives, particularly for vehicles that tackle extreme terrain where suspension articulation places significant stress on drivetrain components. The constant-velocity joint design ensures that power is transmitted smoothly regardless of the angle between the input and output shafts, which is critical in rock crawling applications where suspension droop and compression create dramatic articulation angles. The extended centre driveshaft geometry has been precisely engineered to match the TRX-4M High Trail Edition platform's extended wheelbase, ensuring proper phasing angles and optimal power delivery. This attention to detail prevents driveline vibration, shaft binding, and premature wear that would result from using incorrectly-sized components. As factory-assembled units, these driveshafts have been quality-tested and balanced at the Traxxas factory, guaranteeing that they meet exact specifications and will function flawlessly when installed in compatible vehicles. The assembly-ready format means you avoid the potential for assembly errors that could compromise performance or longevity.

Frequently Asked Questions

• What is the difference between standard TRX-4M driveshafts and these High Trail Edition driveshafts? — The key difference is the extended length of the centre driveshaft, which is specifically engineered to accommodate the longer wheelbase geometry of the TRX-4M High Trail Edition trucks. Standard TRX-4M vehicles have a shorter wheelbase and therefore require shorter driveshafts. Using the wrong length driveshaft can result in binding, poor articulation, and premature wear. Always verify your truck's model before purchasing replacement driveshafts.
• Are these driveshafts suitable for beginners? — While driveshaft replacement is a straightforward maintenance task for most RC enthusiasts, beginners should consult their vehicle's manual or watch installation videos before attempting replacement. The driveshafts themselves are user-friendly replacement parts, but proper installation requires basic mechanical knowledge and the correct tools. If you're unsure about the installation process, we recommend visiting our RC Model Shop store in Walsall where our experienced team can provide guidance and support.
• Can I use these driveshafts on other RC crawlers? — No, these centre driveshafts are specifically engineered and tested for the TRX-4M High Trail Edition platform. They are designed to fit the unique wheelbase and suspension geometry of these vehicles. Using them on other RC crawlers could result in improper fitment, poor performance, and potential damage to other drivetrain components.
• How often should I replace my RC driveshafts? — Driveshaft lifespan depends on usage intensity, terrain difficulty, and maintenance practices. For recreational weekend bashers, driveshafts typically last many months or even years. For competitive crawlers or those used on extreme terrain, replacement intervals may be shorter. Inspect your driveshafts regularly for cracks, bending, or excessive play in the joints. If you notice vibration, clicking, or grinding sounds during operation, it's time to replace your driveshafts.
• Are these driveshafts waterproof? — The driveshaft components themselves are not sealed units, but they are manufactured from steel and durable materials that resist corrosion. After running in wet conditions, rinse your vehicle with fresh water and allow it to dry completely to prevent rust formation on steel components. Regular maintenance will ensure long component life even with frequent water crossing.
• What tools do I need to install these driveshafts? — Installation requirements are minimal and typically involve only basic RC hobby tools like hex wrenches or Allan keys to remove fasteners. Consult your vehicle's manual or the Traxxas website for specific installation instructions and torque specifications. Proper installation ensures optimal performance and longevity of the driveshaft components.
