Overview
The Team Associated RC10B84 FT 39/17 Ring/Pinion Gear Set Steel (AS92568) is a precision-engineered overdrive gear set designed specifically for competitive RC buggy racing on high-grip surfaces. This is a front gearbox component that delivers exceptional tuning flexibility for drivers of 1/10-scale 4WD buggies who demand performance and handling precision. Whether you're an experienced racer fine-tuning your RC car setup or an enthusiast looking to optimise your RC buggy's performance on carpet tracks, this steel gear set offers the durability and reliability that serious competitors expect from Team Associated branded spares and upgrades.
Built to complement the advanced engineering of the RC10B84D and RC10B84 platforms, this overdrive gear set addresses a specific performance need: equalising tyre rollout when front tyres are significantly smaller than rear tyres. This is a common setup choice on high-grip surfaces such as indoor carpet tracks, where precise handling balance and steering consistency are critical to achieving competitive lap times. The 39/17 gear ratio provides the front-end overdrive effect that can meaningfully enhance stability and steering response in these demanding racing conditions. For UK RC enthusiasts and competitors seeking to unlock the full potential of their RC10B84 platform, this is an essential upgrade part that separates good setups from championship-winning ones.
As an authorised Team Associated retailer, RC Model Shop stocks genuine AS92568 gear sets and comprehensive RC10B84 spares and upgrades to help you achieve the exact performance characteristics your buggy demands. This is not a beginner part—it is a purpose-built racing component for drivers who understand the importance of drivetrain tuning and are willing to invest in quality components to achieve consistent, predictable performance on the track.
Key Features
- Steel Construction — Built from durable steel rather than plastic or alloy, this ring and pinion set delivers superior strength and longevity under the demanding conditions of competitive racing, reducing the risk of gear tooth stripping or failure during intense track sessions.
- 39/17 Overdrive Ratio — The 39-tooth ring gear paired with a 17-tooth pinion gear creates an overdrive effect at the front gearbox, a tuning choice specifically designed to equalise tyre rollout when the front tyres are noticeably smaller than the rears—a setup common on high-grip carpet tracks.
- Front Gearbox Application — This gear set is engineered for installation in the front gearbox of the RC10B84 platform, allowing drivers to independently tune front and rear drivetrain characteristics for optimised handling balance.
- Enhanced Stability and Steering Consistency — By providing the correct overdrive ratio, this gear set helps maintain predictable steering response and cornering stability, enabling drivers to maintain confidence and speed through corners on carpet surfaces.
- Precision Racing Tuning Part — This is not a beginner upgrade; it is a precision component for racers who understand drivetrain tuning and are actively working to fine-tune handling balance and corner speed to extract maximum performance from their RC buggy.
- Genuine Team Associated Component — As an official Team Associated part (AS92568), this gear set meets the manufacturing standards and specifications expected by competitive drivers and is compatible with official RC10B84 chassis and drivetrain systems.
Technical Performance
This steel ring and pinion gear set represents precision engineering for 1/10-scale RC buggy racing. The use of steel construction ensures that the gear teeth maintain sharp profiles and resist deformation under the high rotational loads and shock impacts that occur during competitive racing on carpet tracks. Unlike plastic or composite gears that can accumulate wear and develop performance inconsistencies, steel gears deliver consistent performance lap after lap, making them the preferred choice for drivers competing in organised race events or serious practice sessions. The 39/17 ratio is specifically calibrated to address the tyre rollout differential that occurs when front tyres are significantly smaller than rear tyres—a common setup on high-grip surfaces where the mechanical advantage of smaller front tyres must be counterbalanced by a higher (overdrive) front gear ratio to maintain even rollout characteristics across the chassis. This gear pairing allows the front wheels to rotate faster relative to the motor, compensating for their smaller diameter and ensuring that the buggy maintains balanced weight distribution and predictable handling through corners. The engineering team at Team Associated has designed this component to integrate seamlessly with the RC10B84D and RC10B84 front gearbox systems, requiring no modifications or adaptations. Installation requires basic mechanical knowledge and standard RC car tools, making it accessible to experienced builders and racers familiar with RC buggy maintenance and tuning.

Frequently Asked Questions
- What is a ring and pinion gear set, and why would I need it for my RC10B84? — A ring and pinion gear set is the core drivetrain component that translates motor rotation into wheel rotation. The ring gear is the large gear mounted on the differential, and the pinion gear is the smaller gear connected to the motor. By changing the ratio (ring/pinion), you alter how much the wheels turn relative to motor speed. A 39/17 overdrive ratio (more teeth on the ring than typical) means the wheels turn faster relative to motor speed, which is useful when front tyres are smaller than rear tyres to equalise overall rollout and handling balance.
- What does overdrive mean, and when should I use it? — Overdrive refers to a gear ratio where the output (wheels) rotates faster than a standard ratio would produce. The 39/17 ratio in this set provides overdrive at the front gearbox, meaning the front wheels will rotate faster. This is commonly used on high-grip surfaces like carpet tracks when front tyres are noticeably smaller than rear tyres. The overdrive effect helps maintain even tyre rollout across the chassis and can improve steering consistency and cornering stability.
- Is this suitable for beginners? — No. This is a precision racing component intended for experienced racers and builders who understand drivetrain tuning and are actively working to optimise their RC buggy's handling characteristics. Installing and tuning a gear set requires mechanical knowledge, appropriate tools, and understanding of how gear ratios affect performance. Beginners should start with factory-standard gear sets and only upgrade to specific ratios like this 39/17 once they have developed sufficient understanding of RC buggy dynamics and tuning.
- What is the difference between this steel 39/17 set and the plastic moulded gear set? — Team Associated offers a moulded ring and pinion set (part 92543) as an alternative. The steel construction of this AS92568 set offers superior durability, strength, and consistent performance under demanding racing conditions. Steel gears resist tooth deformation and wear better than moulded plastic gears, making them the choice for competitive racing where consistent lap times and reliability are essential. The 39/17 ratio of this steel set specifically provides overdrive, whereas other gear ratios are available depending on your tuning needs.
- Will this work with my RC10B84 or RC10B84D? — Yes, this gear set is specifically designed for and compatible with both the RC10B84 and RC10B84D 1/10-scale 4WD buggy platforms. These are official Team Associated components engineered to integrate seamlessly with the front gearbox system of these chassis.
- How do I install this gear set? — Installation requires removal of the front gearbox and disassembly of the differential. You will need basic RC car tools including hex drivers and possibly a gear puller. The Team Associated RC10B84 team manual and setup guides (available from Team Associated) provide detailed installation instructions. If you are not experienced with differential work, consider having an experienced RC technician perform the installation to ensure proper setup and longevity.
- What makes the 39/17 ratio different from standard gearing? — The 39/17 ratio produces overdrive, meaning higher output speed relative to motor input. Standard ratios typically use larger pinion gears (smaller differences between ring and pinion tooth counts). The 39/17 is specifically chosen for scenarios where you need the front axle to turn faster, which is common when front tyres are smaller than rear tyres on carpet tracks. This ratio helps maintain consistent tyre rollout and balanced handling characteristics.
