Traxxas Spur Gear 50-tooth 32-pitch Drivetrain Component TRX6842

Overview

The Traxxas Spur 50-tooth Gear (Part Number TRX6842) is an essential drivetrain component for serious RC enthusiasts looking to fine-tune and optimise the performance of their Traxxas models. Whether you're running a high-performance brushless RC short course truck, stadium racer, or off-road basher, this genuine Traxxas spur gear allows you to adjust your vehicle's gearing to achieve the perfect balance between acceleration and top speed for your specific running conditions. As an authorised Traxxas dealer, RC Model Shop stocks only genuine replacement parts, ensuring compatibility and reliability with your RC car or truck.

Gearing is one of the most effective and affordable ways to tune your RC model's performance without expensive upgrades or modifications. By switching to different tooth counts, you can prioritise either raw acceleration for tight technical courses, or maximum top speed for open track racing. The 50-tooth configuration represents a popular mid-range option that works well across various Traxxas platforms, making it an ideal spare part to keep in your spares box for competition or casual bashing sessions.

Compatible with several popular Traxxas models including the Rustler Ultimate VXL 4x4 brushless stadium truck and the Slash Ultimate and VXL short course trucks in their various colour variants, this spur gear is designed and manufactured to OEM specifications by Traxxas, guaranteeing perfect fit and durability. UK RC car enthusiasts and bashers trust Traxxas drivetrain components for their reliability and precision engineering.

Key Features

• 50-Tooth Spur Gear Configuration — This 50-tooth spur gear uses a 32-pitch specification (compatible with 0.8 metric pitch), which is the standard tooth profile for numerous Traxxas models, ensuring seamless compatibility with your existing drivetrain components without requiring additional modifications or adapters.
• Performance Tuning — Changing spur gear ratios is one of the most effective ways to fine-tune your RC model's performance characteristics, allowing you to balance acceleration against top speed depending on whether you're racing on technical tight courses or open high-speed tracks, all without expensive engine swaps or major modifications.
• Genuine Traxxas Component — Manufactured to original equipment manufacturer (OEM) specifications by Traxxas themselves, this spur gear meets the exact engineering standards and tolerances required for your RC model, ensuring perfect mesh with your pinion gear and extending the lifespan of your entire drivetrain.
• Wide Model Compatibility — This 50-tooth spur gear fits a range of popular Traxxas brushless RC models including Rustler Ultimate VXL variants and Slash Ultimate and VXL short course trucks, making it a versatile spare part for multi-model enthusiasts and team drivers.
• Essential Spare Part — Every serious RC enthusiast should maintain spares of commonly worn drivetrain components like spur gears, as these parts endure significant stress during regular use and eventual wear is inevitable, especially during competition or aggressive bashing sessions.

Technical Performance

The Traxxas Spur 50-tooth Gear is engineered using durable materials and precision manufacturing techniques to withstand the demanding environment of modern RC racing and bashing. The 32-pitch tooth specification (0.8 metric pitch) is the industry-standard profile for Traxxas drivetrain systems, ensuring perfect engagement with compatible pinion gears and maintaining smooth, efficient power transfer from your brushless motor through the transmission to the wheels. Proper gear meshing is critical for maximising motor efficiency, reducing heat generation in the drivetrain, and minimising wear on both the spur gear and its mating pinion gear. The 50-tooth count represents a mid-range gear ratio that provides a balanced compromise between torque delivery and top speed capability, making it suitable for diverse driving conditions and course layouts. Users consistently report reliable performance across thousands of operating hours, with the component maintaining its tooth profile and avoiding premature wear or stripping when properly installed and maintained. Traxxas' decades of experience in RC manufacturing is evident in the precision engineering of this seemingly simple but critical component.

Frequently Asked Questions

• Which Traxxas models is the 50-tooth spur gear compatible with? — This 50-tooth spur gear (part number TRX6842) is compatible with the Traxxas Rustler Ultimate VXL 4x4 brushless stadium truck (available in blue and green colour variants), the Traxxas Slash Ultimate 4x4 VXL brushless short course truck in orange, and the Traxxas Slash VXL 1/10 4x4 RTR short course trucks in orange, red, blue, and green colours. Always consult your vehicle's owner's manual to confirm compatibility and recommended gearing options for your specific model before installation.
• What is the difference between 32-pitch and other gear specifications? — The 32-pitch specification (compatible with 0.8 metric pitch) refers to the tooth profile and spacing of the gear teeth, which must match your vehicle's pinion gear and spur gear housing for proper engagement. Using incorrect pitch gears will result in poor mesh, excessive noise, premature wear, and potential drivetrain damage, which is why it's essential to confirm your current specification before purchasing replacement gears.
• How does changing the spur gear tooth count affect my RC model's performance? — A higher tooth count spur gear (like this 50-tooth option) combined with your existing pinion gear creates a different overall gear ratio, which alters your vehicle's acceleration and top speed characteristics. Higher tooth count spur gears provide stronger acceleration and better torque delivery but sacrifice top speed, making them ideal for tight, technical courses with lots of turning and acceleration zones, whilst lower tooth count gears favour maximum top speed on open, high-speed tracks.
• When should I replace my spur gear? — Spur gears should be inspected regularly for signs of wear, including stripped or chipped teeth, rounded tooth edges, or visible damage. Worn gears produce increased noise during operation, exhibit poor mesh quality, and can cause damage to your pinion gear and motor shaft. Many RC enthusiasts maintain spare spur gears in their spares box to minimise downtime between races or bashing sessions, allowing quick component swaps when wear becomes apparent.
• Is this a genuine Traxxas part? — Yes, the TRX6842 is a genuine Traxxas component manufactured to OEM specifications, ensuring perfect compatibility and reliability with your Traxxas RC model. Purchasing genuine parts from authorised retailers like RC Model Shop guarantees you receive authentic, quality-assured components rather than counterfeit alternatives that may not fit correctly or meet the required performance standards.
