Overview
The Traxxas 18-T Pinion Gear (1.0 metric pitch) Set is a precision-engineered replacement component designed for serious RC enthusiasts and competitive bashers alike. This machined pinion gear is built to exacting Traxxas standards and represents a critical drivetrain component for maintaining optimal performance in your brushless RC monster truck or short course truck. Whether you're upgrading your RC car UK setup, replacing worn gears after intensive racing, or fine-tuning your gearing ratios for maximum acceleration and top speed, this genuine Traxxas pinion gear delivers the reliability and durability that professionals demand.
Compatibility is extensive, with this gear fitting a range of popular Traxxas models including the Maxx Slash 1/8 4WD brushless short course truck, the legendary Sledge belted monster truck, the WideMaxx, and the X-Maxx Ultimate 8S brushless RTR platform. If you run a high-performance brushless RC truck and need a replacement or spare pinion gear, this is the genuine OEM part that Traxxas engineers recommend. The 5mm shaft bore ensures precise fit and alignment with your motor's pinion shaft, eliminating wobble and maintaining perfect mesh with your steel spur gear for maximum power transfer and longevity.
For the RC hobbyist in the UK looking to maintain peak performance or experiment with gearing changes, the Traxxas 18-T Pinion Gear is an essential spare to keep in your toolbox. Genuine Traxxas parts ensure compatibility, reliability, and the performance characteristics you expect from your investment.
Key Features
- 18-Tooth Precision Count — The 18-tooth configuration is specifically engineered for balanced performance across a range of driving conditions, providing a middle-ground ratio that works effectively with most Traxxas spur gears to deliver responsive acceleration without sacrificing top speed.
- 1.0 Metric Pitch (Mod 1) — This metric pitch specification ensures precise compatibility with matching Traxxas steel spur gears, maintaining exact centre distance and gear mesh for smooth, efficient power delivery with minimal backlash and vibration.
- 5mm Shaft Bore — The 5mm bore diameter is precision-machined to fit snugly onto your motor's pinion shaft, eliminating any possibility of slippage during acceleration or deceleration whilst ensuring the gear sits perfectly centred for optimal mesh with the spur gear.
- Machined Construction — Unlike stamped or moulded alternatives, this gear is precision-machined from high-quality material, delivering superior strength, durability and longevity under the demanding conditions of high-powered brushless RC driving on both track and field.
- Genuine Traxxas OEM Part — As an original equipment manufacturer part, this pinion gear meets Traxxas's strict engineering tolerances and quality standards, ensuring perfect fit and performance in compatible models without the risk of compatibility issues or premature wear.
- Wide Model Compatibility — This single pinion gear fits multiple Traxxas platforms including the Maxx Slash, Sledge monster truck series, WideMaxx, and X-Maxx Ultimate, making it a versatile spare for owners with multiple brushless RC vehicles.
- Compatible with Steel Spur Gears — This pinion gear is specifically designed to mesh perfectly with Traxxas steel spur gears, ensuring optimal power transmission, reduced wear, and extended drivetrain lifespan compared to lower-quality aftermarket combinations.
Technical Performance
The Traxxas 18-T Pinion Gear represents precision engineering at its finest, manufactured to tolerances that ensure flawless engagement with compatible spur gears in high-performance brushless RC applications. With 18 teeth and 1.0 metric pitch specification, this gear delivers a balanced approach to power delivery and top speed characteristics. The 5mm shaft bore is precision-machined to eliminate any play or wobble, critical for maintaining perfect gear mesh alignment when operating under the extreme stresses of 6S or 8S brushless systems. The machined construction ensures consistent tooth geometry and material hardness throughout, preventing the premature tooth stripping or deformation that can occur with inferior gears. When paired with compatible steel spur gears on platforms such as the Traxxas Maxx Slash 1/8 4WD brushless short course truck, Sledge belted 4WD brushless monster truck, WideMaxx monster truck, or X-Maxx belted 4WD brushless RTR monster truck, this pinion gear provides the foundation for responsive acceleration, smooth power delivery, and reliable performance whether you're pushing your RC truck to maximum speed on a flat field or navigating technical terrain. The gear ratio plays a critical role in determining the overall performance characteristics of your brushless system—proper gearing optimises the relationship between motor speed and available torque, maximising both efficiency and usable power delivery across the full RPM range of your brushless motor.

Frequently Asked Questions
- What Traxxas RC trucks is this 18-T pinion gear compatible with? — This genuine Traxxas pinion gear (TRX6491R) is compatible with multiple popular Traxxas brushless platforms including the Maxx Slash 1/8 4WD brushless short course truck (available in red, green, rock n roll, and blue), the Sledge belted 1/8 4WD brushless electric monster truck (green, red, blue, and orange variants), the WideMaxx monster truck (red, rock n roll, and green), and the X-Maxx belted 4WD brushless RTR 8S monster truck (orange, blue, and red), as well as the X-Maxx Ultimate (blue X and green X). This makes it an essential spare for owners of these high-performance brushless RC models.
- Is this suitable for beginners? — This is a replacement pinion gear component, not a complete RC vehicle, so it's designed for users who already own a compatible Traxxas brushless model and understand basic RC maintenance and drivetrain assembly. Beginners should first invest in a ready to run brushless RC truck, then purchase spares like this pinion gear as they gain experience with maintenance and tuning.
- What does 1.0 metric pitch mean? — Metric pitch (also called module) refers to the tooth size specification of the gear. A 1.0 metric pitch ensures this pinion gear meshes perfectly with Traxxas steel spur gears of matching pitch specification. Using mismatched pitches will cause poor gear engagement, excessive wear, and potential drivetrain damage, making authentic Traxxas parts essential.
- Why is a 5mm shaft bore important? — The 5mm shaft bore diameter must match your motor's pinion shaft precisely. A proper fit eliminates any slippage during hard acceleration or deceleration whilst ensuring the gear sits perfectly centred on the shaft, maintaining optimal mesh alignment with your spur gear and preventing vibration, noise, and premature wear.
- Can I use this pinion gear with any spur gear? — No, this pinion gear is specifically designed to work with Traxxas steel spur gears of matching 1.0 metric pitch. The compatibility list provided shows which exact Traxxas models this gear fits. Using incompatible spur gears of different pitch specifications will result in poor engagement and potential damage to both the pinion and spur teeth.
- What is the advantage of a machined pinion gear over alternatives? — Machined gears offer superior strength, precise tooth geometry, and consistent material hardness throughout, compared to stamped or moulded alternatives. This precision engineering translates to longer gear life, smoother power delivery, reduced noise, and more reliable performance under the extreme stresses of high-powered brushless RC driving.
