The Traxxas Spur 83-tooth (48-pitch) gear (part number TRX4683) is an essential performance tuning component for RC enthusiasts in the UK who want to optimise the acceleration and top speed characteristics of their Traxxas models. This spur gear is specifically designed for Traxxas vehicles equipped with Torque-Control slipper clutches, making it a direct replacement or upgrade component for a wide range of ready-to-run RC cars and trucks. Whether you're running a Traxxas Slash short course truck, a Ford Fiesta ST Rally brushless RC car, or any other compatible Traxxas model, changing your spur gear ratio is one of the most effective ways to fine-tune your RC car's performance for different running conditions and terrain types.

For serious RC hobbyists and casual bashers alike, understanding gear ratios is fundamental to getting the best from your RC vehicle. The 83-tooth spur gear offers a specific gear ratio that allows you to balance the fundamental trade-off between raw acceleration and maximum top speed. This genuine Traxxas component is engineered to the exacting standards you'd expect from the world's leading RC manufacturer, ensuring compatibility, durability and reliable performance. Whether you're upgrading from a lower or higher tooth count spur gear, or replacing a worn component, this 48-pitch spur gear delivers the quality and precision that Traxxas is renowned for across the RC model shop community in the UK.

The Traxxas Spur 83-tooth gear is part of Traxxas's complete selection of 48-pitch spur gears available for performance tuning. These gears allow you to dial in your vehicle's performance precisely, whether you're preparing for racing, weekend bashing, or casual backyard fun. The modular nature of Traxxas drivetrain components means you can experiment with different gear ratios to find the perfect setup for your driving style and local track or terrain conditions.

Key Features

• 83-tooth design — This specific tooth count provides a particular gear ratio that affects how your RC model accelerates and reaches top speed, allowing you to optimise performance based on whether you prioritise quick acceleration or maximum velocity.
• 48-pitch specification — The 48-pitch standard ensures compatibility with a wide range of Traxxas models and allows you to match spur and pinion gears correctly for smooth, efficient power transmission throughout your drivetrain.
• Torque-Control slipper clutch compatibility — This gear is engineered specifically for Traxxas models equipped with Torque-Control slipper clutch systems, which automatically slip to protect your drivetrain from damage during high-load situations and collisions, extending the life of your RC car's internal components.
• Genuine Traxxas engineering — As an authentic Traxxas spare part, this spur gear is manufactured to the same exacting quality standards as the original components in your RC vehicle, ensuring reliable performance and longevity.
• Performance tuning flexibility — By swapping different tooth count spur gears, you can adjust your model's acceleration curve and top speed without needing to purchase an entirely new vehicle, making gear changes a cost-effective way to experiment with different driving characteristics.
• Direct compatibility — This component is designed as a direct fit for multiple Traxxas models including the Slash 1/10 2WD RTR brushless short course truck, Slash HD XL-5, Slash Extreme HD VXL, and Ford Fiesta ST Rally vehicles, making it a versatile upgrade option for UK RC enthusiasts with these models.

Technical Performance

The Traxxas Spur 83-tooth (48-pitch) gear is a precision-engineered drivetrain component manufactured to deliver reliable power transmission and consistent performance across a range of driving conditions. As a spur gear, this component works in conjunction with your vehicle's pinion gear to create the primary gear ratio that determines how power from the motor is translated into wheel speed and acceleration. The 83-tooth configuration represents a mid-range tooth count within the 48-pitch spur gear family, positioning it as a balanced option that neither sacrifices maximum top speed nor initial acceleration excessively. The 48-pitch specification ensures that this gear meshes perfectly with compatible 48-pitch pinion gears, maintaining smooth engagement, minimal backlash, and efficient power transfer. Built for use with Torque-Control slipper clutch systems, this gear works as part of Traxxas's sophisticated drivetrain protection technology, which automatically allows the clutch to slip under extreme load, protecting downstream drivetrain components from sudden shock loads and impact damage. The gear is manufactured from durable materials selected to withstand the stresses of repeated acceleration cycles, impacts and the demanding conditions of both on-road racing and off-road bashing. Whether you're running on a smooth tarmac track, a grass field, or a rocky terrain at your local RC racing venue in the UK, this spur gear is engineered to provide consistent performance and reliability. For users of the Traxxas Slash range and Ford Fiesta ST Rally brushless RC models, this gear represents a proven upgrade path that has been tested across hundreds of thousands of RC cars worldwide.

Frequently Asked Questions

• Which Traxxas RC cars and trucks are compatible with the TRX4683 83-tooth spur gear? — This spur gear is compatible with multiple Traxxas models equipped with Torque-Control slipper clutches, including the Traxxas Ford Fiesta ST Rally BL-2S Rally Car, the Traxxas Ford Fiesta ST Rally VXL, the Traxxas Slash HD XL-5 1/10 2WD RTR Short Course Truck, the Traxxas Slash 1/10 2WD RTR VXL-3S Brushless Short Course Truck, and the Traxxas Slash Extreme HD VXL 1/10 2WD RTR Brushless Electric Short Course Truck in multiple colour options. Always consult your vehicle's owner's manual to confirm compatibility with your specific model variant.
• How does changing spur gear tooth count affect my RC car's performance? — Spur gear tooth count directly affects the gear ratio of your vehicle. A higher tooth count (numerically larger) on the spur gear lowers the overall gear ratio, increasing top speed but reducing acceleration. Conversely, a lower tooth count on the spur gear increases the gear ratio, providing stronger acceleration but limiting maximum speed. The 83-tooth gear in this product offers a balanced middle ground that many users find ideal for mixed driving conditions.
• What does 48-pitch mean on RC gears? — Pitch refers to the size and spacing of the gear teeth. 48-pitch is a standard specification in the RC hobby that ensures proper meshing between spur and pinion gears. The 48-pitch specification means you must pair this spur gear with a 48-pitch pinion gear to achieve correct engagement, smooth operation and efficient power transmission.
• Is this a genuine Traxxas product? — Yes, this is an authentic Traxxas spare part manufactured to the same quality standards as all original Traxxas components. As a genuine part, it carries the reliability and compatibility assurances you expect from Traxxas, the world's leading RC manufacturer.
• Do I need any special tools to install this spur gear? — Installation procedures vary depending on your specific Traxxas model. Consult your vehicle's owner's manual for detailed installation instructions, required tools and torque specifications. Most Traxxas RC vehicles use a spur gear removal tool or Allen wrench to complete the swap, though specific requirements depend on your model.
• What is a Torque-Control slipper clutch and why is this gear designed for it? — Traxxas Torque-Control slipper clutches are intelligent drivetrain protection systems that automatically slip when your RC car experiences sudden impact, hard acceleration from a standstill, or collision-level forces. This slipping action protects your vehicle's internal gears, driveshafts and differential from catastrophic damage. This spur gear is specifically engineered to work reliably with these systems, maintaining the proper clutch engagement characteristics and protection performance.
• Can I use this spur gear as a direct replacement in my existing Traxxas RC model? — If your Traxxas model is equipped with a Torque-Control slipper clutch and currently uses a 48-pitch spur gear, this 83-tooth component can serve as a direct replacement. However, swapping from a different tooth count will change your vehicle's performance characteristics. Refer to your owner's manual for recommended gearing options and guidance on balancing spur and pinion gear selections for your specific running conditions.
