Key Features
- Built-in Spring Tensioner — The integrated spring mechanism maintains consistent tension throughout the differential locking cycle, preventing slack and ensuring smooth, predictable engagement when shifting between locked and open differential modes. This feature dramatically improves drivability on challenging terrain.
- Complete Hardware Included — Every fastener and mounting component you need comes in the box, eliminating the frustration of hunting for compatible hardware and ensuring proper fitment to your TRX-6 vehicle immediately upon purchase.
- Genuine Traxxas OEM Component — This is authentic Traxxas factory-engineered equipment, not an aftermarket alternative, guaranteeing compatibility and performance with your existing TRX-6 platform and its differential locking system.
- Precision Plastic Construction — The servo horn is manufactured from durable engineering polymer that strikes the perfect balance between strength and weight, withstanding the demands of rock crawling and off-road exploration without adding unnecessary mass to your vehicle.
- Direct Fit for TRX-6 Models — Engineered specifically for Traxxas TRX-6 platforms including the Mercedes-Benz G 63 AMG XL-5 and Ultimate RC Hauler with Winch, ensuring perfect alignment and functionality without modification or adaptation.
- Reliable Spring Action — The spring-loaded design eliminates play and improves responsiveness of your differential locking mechanism, which is critical when navigating obstacles or switching between terrain types during serious RC crawling sessions.
Technical Performance
This Traxxas servo horn represents the engineering excellence you expect from Traxxas's factory components. The shift servo horn with built-in spring tensioner is manufactured to the highest standards, using quality materials that withstand the repeated cycling and significant loads inherent in differential locking systems on 1/10 scale 6x6 crawlers. The integrated spring mechanism is pre-calibrated to provide optimal tension without over-stressing your servo motor, protecting your electronic components whilst maintaining crisp, responsive engagement. The precision moulding ensures tight tolerances that eliminate rattling or binding, whilst the included hardware is specification-matched for reliability. When used with compatible TRX-6 platforms, this servo horn delivers the smooth, predictable performance that separates genuine Traxxas components from generic alternatives. The durable material resists UV degradation and chemical damage from typical RC environments, whether you're driving through water crossings, dusty terrain, or challenging rock gardens across the UK.

Frequently Asked Questions
- Is this servo horn compatible with my TRX-6 RC crawler? — This component is specifically designed for Traxxas TRX-6 models, including the TRX-6 Mercedes-Benz G 63 AMG XL-5 (available in both black and silver), the TRX-6 Ultimate RC Hauler with Winch in black, and other compatible TRX-6 platforms. Check your model number to confirm compatibility before ordering.
- What does the built-in spring tensioner do? — The spring tensioner maintains consistent pressure on the differential locking mechanism, ensuring smooth engagement and disengagement when your servo switches between locked and open modes. This reduces wear on components and improves overall responsiveness during challenging rock crawling sessions.
- Is installation difficult? — Installation is straightforward for anyone with basic RC maintenance experience. The servo horn comes complete with all necessary hardware, and detailed instructions are typically available on the Traxxas website or in your vehicle's manual. If you're unfamiliar with servo horn installation, our team at RC Model Shop can provide guidance or installation support.
- Why would I need to replace my original servo horn? — Servo horns can become damaged through normal wear, impacts, or accidental damage during off-road adventures. Having a genuine replacement on hand ensures you can quickly restore full differential locking functionality without extended downtime from your RC crawling activities.
- Is this a genuine Traxxas part? — Yes, this is an authentic Traxxas OEM component with part number TRX8843, ensuring perfect compatibility and the quality standards you expect from genuine factory parts. Authorised retailers like RC Model Shop stock only genuine Traxxas components.
- Will this improve my TRX-6's performance? — If your current servo horn is worn or damaged, upgrading to a new OEM unit will restore smooth differential engagement and improve handling characteristics on challenging terrain. If your existing horn is in good condition, you likely won't notice a dramatic performance change, but preventative replacement keeps your crawler in peak condition.
