Traxxas Spur Gear 72-Tooth 48 Pitch 4TEC 3.0 Corvette Stingray TRX8368

Overview

The Traxxas Spur Gear 72-tooth (48 pitch) TRX8368 is an essential replacement drivetrain component designed specifically for the Traxxas 4TEC 3.0 Chevrolet Corvette Stingray 1/10 scale AWD supercar. Whether you're a serious competitor looking to fine-tune your RC car UK setup, a weekend basher maintaining your vehicle, or an enthusiast exploring the world of performance tuning, this genuine Traxxas spare part ensures your transmission operates at peak efficiency. The spur gear is a critical element in the drivetrain system, directly influencing acceleration, top speed capability, and overall power delivery from your brushless motor to the wheels.

As an authorised Traxxas retailer, RC Model Shop supplies only genuine OEM components that guarantee perfect compatibility with your 4TEC 3.0. This 72-tooth spur gear represents the optimal balance for high-performance driving, offering the right gear ratio to maximise both speed and torque delivery. When your existing spur gear becomes worn, damaged, or stripped from intense driving sessions, a replacement is essential to maintain the responsive handling and predictable power characteristics your Corvette Stingray demands. Traxxas spare parts are engineered to the same exacting standards as the vehicles themselves, ensuring longevity and reliability in competitive and recreational driving alike.

Proper drivetrain maintenance is fundamental to keeping your RC car in top condition. The spur gear undergoes constant stress during acceleration and deceleration, and over time, the teeth can wear or sustain damage from impacts or aggressive driving. This genuine Traxxas TRX8368 spur gear is the direct replacement your 4TEC 3.0 needs, restoring smooth gear mesh, crisp throttle response, and consistent performance characteristics that separate a well-maintained RC vehicle from one suffering from drivetrain wear.

Technical Performance

The Traxxas Spur Gear TRX8368 is engineered from durable materials capable of withstanding the intense forces generated by brushless motors in the 4TEC 3.0 platform. At 72 teeth in a 48-pitch configuration, this gear delivers the precise gear ratio that Traxxas engineers designed specifically for the 4TEC 3.0's advanced all-wheel-drive system. The tooth profile is optimised for smooth meshing with the pinion gear, minimising backlash and ensuring crisp, responsive throttle feel. In competitive ready-to-run RC car UK applications, proper spur gear condition is critical for consistent lap times and predictable handling characteristics. The 48-pitch standard ensures compatibility with the OEM pinion gear, and replacement is straightforward when wear becomes evident through reduced acceleration response or grinding noises during operation. Traxxas manufactures this component to the same engineering specifications used in their factory racing programs, meaning it's equally suitable for weekend bashers and serious competitors alike. The spur gear's design balances the need for high-speed capability with sufficient torque for quick acceleration off the line, making it ideal for both straight-line speed runs and the varied demands of circuit racing. Proper drivetrain maintenance, including spur gear replacement when necessary, is essential for maintaining the durability and performance characteristics of your 4TEC 3.0 platform and ensuring optimal engagement between components in the transmission system.

Frequently Asked Questions

• What is the purpose of a spur gear in an RC car? — The spur gear is a critical drivetrain component that meshes with the pinion gear (driven by the motor) to transfer power to the transmission output. The tooth count determines the gear ratio, which directly affects acceleration and top-end speed. In the 4TEC 3.0, the 72-tooth spur gear provides the optimal balance for this advanced AWD supercar platform, allowing the brushless motor to deliver power efficiently to all four wheels.
• Why would I need to replace my spur gear? — Spur gears wear over time due to constant meshing with the pinion gear during normal driving. Aggressive driving, impacts, and long-term use cause the teeth to wear down or sustain damage. When wear becomes significant, you'll notice reduced acceleration response, grinding noises, or loss of efficiency. A genuine replacement like the TRX8368 restores full drivetrain performance and ensures smooth power delivery.
• Is this spur gear compatible with both silver and black 4TEC 3.0 models? — Yes, this TRX8368 spur gear is compatible with both the Traxxas 4TEC 3.0 Chevrolet Corvette Stingray in silver and black colour variants. The drivetrain specification is identical across both colour options, so this component works universally with any 4TEC 3.0 platform regardless of body colour.
• What does 48-pitch mean, and why is it important? — The 48-pitch specification refers to the gear tooth spacing standard. It must match your pinion gear's pitch to ensure proper meshing and smooth power transmission. Using a gear with the wrong pitch will result in poor engagement, increased noise, and potential drivetrain damage. The 48-pitch specification used in the 4TEC 3.0 is an industry-standard sizing that Traxxas engineered specifically for this platform.
• How difficult is it to replace the spur gear on my 4TEC 3.0? — Spur gear replacement on the 4TEC 3.0 is relatively straightforward and falls within the capabilities of most RC enthusiasts. You'll need to access the transmission housing and secure the pinion gear whilst removing the worn spur gear. Most drivers can complete this maintenance task in 30 minutes to an hour. If you're unsure about the process, our team at RC Model Shop can provide guidance or support.
• Will upgrading to a different tooth count give me better performance? — The 72-tooth spur gear is the specification designed and tested by Traxxas for optimal performance on the 4TEC 3.0. Changing the tooth count alters the gear ratio and would shift the balance between acceleration and top speed. For most drivers, the standard 72-tooth configuration delivers the best all-round performance. If you have specific performance goals, our experienced team can discuss gear ratio options with you.
