Key Features
- 6.8:1 Reduction Ratio — This specific gear ratio provides an excellent balance between acceleration response and top speed capability, allowing your RC vehicle to deliver power efficiently across a wide range of driving conditions and terrain types. The 6.8:1 ratio is particularly effective for vehicles using portal drive axles, optimising the power transfer through your drivetrain for maximum performance.
- Portal Drive Axle Compatibility — This transmission gear set is engineered exclusively for use with portal drive axles, ensuring perfect fitment and performance with compatible vehicles. Portal drive systems are known for their strength and durability in high-performance RC applications, and this gear set maximises the potential of that system.
- Genuine Traxxas Manufacturing — As an official Traxxas component, this gear set is manufactured to the exact specifications and quality standards that Traxxas is renowned for worldwide. You're getting a component that has been tested and validated by the engineers at Traxxas to deliver consistent, reliable performance.
- Distinctive Red Colour — The bright red finish not only looks professional and distinctive on your RC vehicle, but also makes it easy to identify these gears during maintenance and rebuilds. The colour serves both aesthetic and practical purposes in your workshop.
- Precision-Engineered Teeth — The transmission gears feature precision-cut teeth that ensure smooth, efficient power transfer with minimal backlash. This precision engineering reduces wear on connected components and delivers more responsive handling characteristics to your RC car.
- Durable Construction — Built from materials specifically selected for strength and longevity, these gears are designed to withstand the stresses of competitive racing, aggressive bashing, and regular use in challenging conditions across the UK and beyond.
Technical Performance
The Traxxas Gear Set TRX9776A is a critical component in your vehicle's drivetrain system, directly influencing how power is delivered from the motor to the wheels through the portal drive axles. The 6.8:1 reduction ratio means that for every 6.8 rotations of the input shaft, the output shaft completes one full rotation, effectively increasing torque while moderating top speed. This ratio has been carefully selected by Traxxas engineers to provide an optimal sweet spot for vehicles equipped with portal drive systems, which are known for their heavy-duty construction and superior strength compared to standard axle designs. The precision manufacturing of the gear teeth ensures minimal backlash (the gap between meshing teeth), which translates to more responsive handling, improved traction, and better power delivery to your wheels. The red-coloured gears are manufactured from high-quality materials that have been heat-treated and hardened to withstand the enormous stresses placed upon them during acceleration, cornering, and off-road driving. When properly installed in a vehicle with portal drive axles, this gear set will provide smooth, efficient operation with excellent reliability across countless hours of driving, whether you're tackling competitive racing events or enjoying weekend bashing sessions across varied terrain throughout the United Kingdom.

Frequently Asked Questions
- Which Traxxas models use portal drive axles and work with the TRX9776A? — Portal drive axles are found on premium Traxxas models designed for maximum strength and performance. If your RC vehicle is equipped with portal drive axles, this transmission gear set will be compatible. Check your vehicle's manual or contact our team at RC Model Shop if you're unsure whether your specific model features portal drives.
- What does the 6.8:1 reduction ratio mean for my RC car's performance? — The 6.8:1 reduction ratio means that the output shaft rotates one complete turn for every 6.8 rotations of the input shaft, effectively multiplying the torque available at the wheels whilst moderating the top speed of your vehicle. This particular ratio is optimised for portal drive systems and provides excellent acceleration response with balanced top-end performance suitable for varied driving conditions.
- How often should I replace my transmission gear set? — With proper maintenance and use, transmission gears can last for many months or even years of regular operation. However, if you notice increased noise from the transmission, difficulty engaging gears, or reduced responsiveness, it may be time to inspect and potentially replace your gears. High-performance racing or aggressive bashing can wear gears faster than casual recreational driving.
- Is this suitable for beginners? — Transmission gear replacement is a moderate-level maintenance task that requires some mechanical knowledge and the correct tools. Beginners should feel confident attempting this replacement if they have basic mechanical aptitude, though we recommend consulting your vehicle's instruction manual or watching tutorial videos before starting. Our team at RC Model Shop is always happy to provide guidance.
- Can I use this gear set with non-portal drive axles? — No, this transmission gear set is specifically engineered for use only with portal drive axles. Using it with other axle types could result in fitment issues, poor performance, or component damage. Always verify that your vehicle is equipped with portal drives before ordering this part.
- What is the difference between 6.8:1 and other reduction ratios? — Lower ratio numbers (like 5:1) provide higher top speeds but less torque, whilst higher ratio numbers (like 8:1) provide more torque and acceleration but lower top speeds. The 6.8:1 ratio of this gear set strikes a balance suitable for portal drive vehicles, offering responsive acceleration with reasonable top speed capability across diverse driving scenarios.
