Key Features
- Complete Servo Saver Assembly — This replacement bellcrank includes a brand new servo saver mechanism that protects your steering servo against impacts and collisions, absorbing shock loads that would otherwise damage internal servo components and dramatically reduce servo lifespan.
- Servo Saver Spring Included — The servo saver spring provides progressive resistance and compliance, allowing controlled flex in the steering linkage whilst maintaining precise control and preventing permanent damage from hard impacts with obstacles.
- Three Replacement Servo Horns — This assembly provides three servo horns offering different steering geometry options, allowing you to fine-tune your steering response and find the perfect balance between sensitivity and control for your driving style and terrain conditions.
- Servo Spring Retainer — A dedicated spring retainer keeps the servo saver spring properly tensioned and positioned, ensuring consistent performance and preventing the spring from shifting or coming loose during aggressive driving sessions.
- Complete Hardware Package — All necessary fasteners, linkage components, and drag link hardware are included, making this a complete steering solution that requires no additional parts sourcing.
- Factory-Engineered Design — As an official Traxxas OEM part, this steering assembly has been developed and tested to work perfectly with the UDR platform, guaranteeing compatibility and performance that aftermarket alternatives cannot match.
- Drag Link Included — The complete drag link assembly is provided, eliminating the need to source this critical steering component separately and ensuring all components work together harmoniously.
Technical Performance
The Traxxas Steering Bellcranks assembly represents precision engineering at its finest, combining aluminium-constructed bellcranks with carefully calculated linkage geometry to deliver responsive, accurate steering control. The servo saver mechanism operates through a spring-loaded design that allows the steering linkage to flex slightly when encountering obstacles, absorbing impact energy that would otherwise be transmitted directly to your servo motor's internal gears and bearings. This technology is particularly valuable when driving demanding RC trucks like the UDR, which frequently encounter rocks, jumps, and rough terrain that generate substantial impact loads. The inclusion of three separate servo horns demonstrates Traxxas's commitment to allowing drivers to customise their steering response; different horn positions change the servo lever arm length, directly affecting steering speed and control sensitivity. The spring retainer ensures that the servo saver spring maintains consistent preload throughout extended driving sessions, preventing performance degradation as the spring settles. All hardware has been selected for durability and corrosion resistance, critical for UK drivers who frequently encounter wet conditions and salt exposure. The drag link component completes the steering assembly, providing the mechanical linkage between your servo horn and the steering bellcrank mechanism that translates servo input into actual wheel movement.

Frequently Asked Questions
- What is a servo saver and why do I need one on my RC truck? — A servo saver is a mechanical protection device that absorbs impact forces and vibrations before they reach your steering servo motor. When your RC truck hits obstacles or lands jumps at speed, the servo saver's spring-loaded design allows the steering linkage to flex slightly, dissipating that energy rather than transmitting it directly to your servo's internal gears. This protection dramatically extends servo lifespan and prevents expensive servo failures that could otherwise occur from regular bashing and aggressive driving.
- Is this part compatible with my Traxxas UDR? — Yes, this steering assembly is specifically designed and engineered for the Traxxas UDR Unlimited Desert Racer platform. It is compatible with both the UDR 4WD Short Course Truck with Fox Racing suspension (TRX85086-4-FOX1) and the version with Rigid Industries lighting (TRX85086-4-RGD1). Always verify your UDR model before ordering to ensure compatibility.
- What is the advantage of having three servo horns? — The three servo horns provided in this assembly offer different lever arm lengths and mounting positions. By selecting different horns, you can adjust your steering response characteristics; a longer horn lever arm provides faster, more sensitive steering, whilst a shorter horn provides slower, more stable steering. This allows you to fine-tune your truck's handling to match your driving style and the terrain you're racing on.
- How often should I replace my servo saver assembly? — The lifespan of a servo saver depends on driving intensity and conditions. Serious racers may replace theirs every few months, whilst recreational drivers might go much longer. If you notice your steering feeling spongy, unresponsive, or if the servo saver spring appears damaged or permanently deformed, it's time to replace the assembly. Regular inspection during routine maintenance will help you catch wear before it affects performance.
- Can I upgrade my existing servo saver or must I replace the entire assembly? — This assembly includes the servo saver spring and retainer as individual components alongside the complete bellcrank mechanism. Depending on what components are worn, you might replace just the spring or the entire assembly. If your bellcranks are bent or damaged, however, you'll need the complete replacement assembly to ensure proper steering geometry and performance.
- Is this suitable for beginners? — This is a replacement part rather than a complete truck, so it's intended for anyone already owning a Traxxas UDR who needs to maintain or repair their steering system. If you're new to RC and considering purchasing a UDR, you'll appreciate that the quality engineering in components like this steering assembly is one reason the UDR is a fantastic choice for serious RC enthusiasts at all skill levels.
