Overview

The Traxxas Gearbox Halves (Front & Rear) TRX3991X are essential replacement components designed specifically for the E-Maxx RC monster truck platform. Whether you are an experienced RC enthusiast maintaining your high-performance off-road machine or a dedicated basher looking to keep your E-Maxx running at peak performance, these gearbox halves represent genuine Traxxas engineering that ensures reliability and durability through demanding terrain and intense driving sessions. As an authorised Traxxas retailer, RC Model Shop stocks this authentic spare part to help UK RC car enthusiasts maintain their vehicles to the highest standards.

Gearbox halves form a critical part of your RC car's transmission system, housing and protecting the internal gear mechanisms that transfer power from the motor to the wheels. The E-Maxx is renowned for its ability to handle aggressive driving styles and challenging outdoor environments, making quality replacement gearbox components essential for long-term reliability. When wear occurs through normal use, or damage happens during intense bashing sessions, having access to genuine Traxxas gearbox halves ensures you can restore your RC model to factory specifications.

This pack includes both front and rear gearbox halves, providing a complete solution for transmission maintenance on your E-Maxx. By choosing genuine Traxxas parts, you guarantee compatibility with your existing components and maintain the performance characteristics that make the E-Maxx one of the most popular large-scale RC monster trucks available in the UK market today.

Key Features

  • Front and Rear Halves Included — This product provides both front and rear gearbox halves in a single package, allowing you to service your E-Maxx transmission completely without needing to purchase multiple separate items or source components from different suppliers.
  • Genuine Traxxas Engineering — These gearbox halves are manufactured to Traxxas specifications, ensuring perfect fitment with your existing E-Maxx components and maintaining the durability and performance characteristics that the E-Maxx platform is known for across the RC hobby community.
  • Designed for E-Maxx Compatibility — Purpose-built for the E-Maxx RC monster truck platform, these gearbox halves integrate seamlessly with your existing transmission system, gear sets and internal components without modification or adaptation.
  • Essential Maintenance Component — Gearbox halves experience wear during normal operation and may require replacement after extensive driving or following damage from impacts during off-road bashing sessions, making this a crucial spare part for E-Maxx owners.
  • Authentic OEM Part — By sourcing this component from an authorised Traxxas retailer, you receive genuine original equipment manufacturer parts rather than aftermarket alternatives, guaranteeing quality and longevity.

Technical Performance

The gearbox halves are precision-engineered components that house the transmission mechanics of your Traxxas E-Maxx. These halves work in conjunction with the internal gear train to deliver power from your brushless motor system to the front and rear driveshafts, ultimately providing traction to all four wheels of your RC monster truck. The E-Maxx platform is engineered to handle high levels of torque and stress during aggressive off-road driving, jumps, and bashful exploration of challenging terrain. The gearbox halves must therefore be manufactured to withstand these demanding conditions whilst maintaining precise tolerances to ensure smooth operation and minimal friction within the transmission system. When these components show signs of wear—evidenced by grinding sounds, leaking lubricant, or binding during rotation—replacement with genuine Traxxas gearbox halves restores your transmission to factory condition. The material composition and manufacturing standards ensure compatibility with both 2S and 3S LiPo battery systems commonly used to power modern E-Maxx builds in the UK RC hobby scene. Proper assembly of these gearbox halves with appropriate gear lubricant ensures optimal performance, quieter operation, and extended lifespan of your entire transmission system.

Frequently Asked Questions

  • What is the purpose of gearbox halves in my RC monster truck? — Gearbox halves are the two-piece casing that houses your transmission's internal gears and mechanisms. They work together to protect the gear train whilst allowing smooth power transfer from your motor to your wheels. When damaged or worn, replacement halves restore proper transmission function and reliability to your E-Maxx.
  • Will these gearbox halves fit my Traxxas E-Maxx? — Yes, these gearbox halves are purpose-designed for the Traxxas E-Maxx platform and will integrate seamlessly with your existing E-Maxx components. As a genuine Traxxas OEM part, fitment and compatibility are guaranteed without modification required.
  • Do I need both front and rear halves or just one? — This pack includes both front and rear gearbox halves, allowing you to service your complete transmission system in one purchase. Depending on your needs, you may only require one set, but having both available provides a comprehensive solution.
  • How do I know if my gearbox halves need replacement? — Signs that gearbox halves may need replacement include grinding or unusual sounds from the transmission, visible cracks or damage to the casing, gear lubricant leaking from the transmission area, or binding resistance when manually rotating the wheels. If you suspect damage, inspection of the gearbox halves should be your first troubleshooting step.
  • What tools do I need to install these gearbox halves? — Installation requires basic RC model tools including hex drivers, a torque wrench for proper fastener tightening, and gear lubricant appropriate for RC transmissions. Detailed assembly instructions specific to E-Maxx gearbox service should be consulted before beginning work.
  • Can these gearbox halves be used for other Traxxas models? — These halves are specifically engineered for the E-Maxx platform. Whilst some Traxxas models may share transmission architecture, these components are optimised for E-Maxx fitment. Always verify compatibility before purchasing replacement parts for other models.
