Traxxas 18-T Pinion Gear Mod 1.0 Metric Pitch 5mm Bore TRX6491X

Overview

The Traxxas 18-T Pinion Gear (1.0 metric pitch) Set with 5mm shaft (model TRX6491X) is an essential upgrade and replacement component for serious RC enthusiasts running high-performance Traxxas models across the UK. Whether you're a dedicated basher, weekend racer, or competitive RC car enthusiast, having quality pinion gears in your spares collection is crucial for maintaining peak performance and ensuring uninterrupted track or bash sessions. This hardened steel pinion gear represents genuine Traxxas engineering and reliability, designed to work seamlessly with the extensive range of Traxxas spur gears available to RC modellers in the UK.

Pinion gears are fundamental drivetrain components that transfer power from your brushless motor to the main spur gear, ultimately driving your wheels forward. The quality of your pinion gear directly impacts acceleration, top speed potential, and overall drivetrain durability. When you invest in genuine Traxxas components like this 18-tooth pinion gear, you're ensuring that your RC vehicle performs at its absolute best whilst maintaining the reliability and longevity that competitive and recreational drivers depend on. Whether you're running a Traxxas Maxx Slash, WideMaxx monster truck, X-Maxx, or XRT, having the correct pinion gear is non-negotiable for optimal performance.

This pinion gear set comes ready to install and includes everything needed to get your RC car back into action quickly. The 18-tooth configuration provides a balanced approach to gearing, offering a sweet spot between acceleration and top speed for most RC bashing and racing applications. Available at RC Model Shop with expert support from our experienced team, this is the genuine Traxxas spare part that serious RC enthusiasts reach for when they want reliability and performance they can trust.

Key Features

• Hardened Steel Construction — This pinion gear is manufactured from hardened steel, which provides exceptional durability and resistance to wear even under the demanding conditions of high-speed bashing or competitive racing. Hardened steel gears maintain their tooth profile longer than softer materials, ensuring consistent performance over extended periods of use.
• 5mm Bore Shaft Fitting — The gear features a precisely engineered 5mm bore that fits standard motor shafts found across the Traxxas range, including the high-performance brushless motors in Traxxas's most popular models. This standardised fitment ensures compatibility and easy installation without modification.
• Mod 1.0 Metric Pitch — The Mod 1.0 tooth pitch specification means this gear is precisely engineered to mesh smoothly and efficiently with Traxxas steel spur gears. This metric pitch standardisation ensures minimal backlash, maximum power transfer, and optimal drivetrain efficiency during acceleration and cornering.
• 18-Tooth Count — The 18-tooth configuration strikes an excellent balance for most RC applications, offering strong acceleration whilst maintaining reasonable top-speed potential. This tooth count is ideal for both on-road and off-road driving, making it one of the most versatile pinion gear options available for Traxxas models.
• Includes Set Screw — The package comes complete with a set screw for secure fastening to your motor shaft. This prevents any possibility of the gear slipping or rotating on the shaft during operation, ensuring reliable power delivery and safe driving.
• Compatible with Multiple Traxxas Models — This pinion gear works across an extensive range of current Traxxas brushless vehicles, including the Maxx Slash, WideMaxx, X-Maxx Belted, X-Maxx Ultimate, and XRT families, making it an essential spare for collectors and multi-model enthusiasts.

Technical Performance

The Traxxas 18-T Pinion Gear represents the pinnacle of precision engineering in RC drivetrain components. Manufactured from hardened steel and finished to exacting tolerances, this gear ensures that power from your high-output brushless motor is transferred efficiently and reliably to your spur gear and ultimately to the wheels. The Mod 1.0 metric pitch specification is industry-standard for modern Traxxas models, meaning it meshes perfectly with genuine Traxxas steel spur gears without excessive backlash that could compromise performance or cause premature wear. The 5mm bore is precisely machined to accommodate standard Traxxas brushless motor shafts, and when secured with the included set screw, the gear remains absolutely rigid during operation. The 18-tooth configuration represents an excellent compromise between rapid acceleration and sustainable top speed, making it suitable for both casual bashing in gardens and parks across the UK and more competitive racing environments. Whether you're running this gear on a 6S or 8S brushless system in models like the X-Maxx Ultimate or Maxx Slash, the hardened steel construction guarantees longevity and consistent performance lap after lap or bash session after bash session.

Frequently Asked Questions

• Which Traxxas models is the TRX6491X compatible with? — This 18-tooth pinion gear is compatible with a comprehensive range of Traxxas brushless vehicles, including the Maxx Slash 1/8 4WD 6S Brushless Short Course Truck (all colour variants), WideMaxx Monster Truck range, X-Maxx Belted 4WD Brushless 8S Monster Truck, X-Maxx Ultimate, X-Monster Chassis, and the XRT family of models. Always verify your specific model number against the compatibility list before ordering, though this gear is one of the most widely compatible Traxxas components available.
• What is the difference between Mod 1.0 and metric pitch specifications? — Mod 1.0 refers to the module system, which is the metric equivalent to diametral pitch used in imperial measurements. This specification defines the relationship between tooth count, pitch diameter, and centre distance between meshing gears. Traxxas uses Mod 1.0 across its modern brushless vehicle range, ensuring that all gears within a model are precisely compatible and mesh without backlash or binding.
• Is this pinion gear suitable for beginners? — Yes, this is an excellent pinion gear for users of all skill levels. The 18-tooth count is one of the most popular configurations and offers a balanced driving experience. Beginners will appreciate the predictable acceleration and moderate top speed, whilst experienced drivers benefit from the hardened steel durability during aggressive bashing. If you're new to RC cars in the UK, the 18-tooth pinion is an excellent starting point before experimenting with alternative tooth counts.
• How do I install this pinion gear? — Installation is straightforward: remove your motor from its mounting bracket, carefully slide the old pinion gear off the motor shaft, slide the new Traxxas 18-T gear onto the shaft, and secure it with the included set screw. Ensure the set screw is tightened adequately so the gear cannot slip during operation, but do not over-tighten as this could damage the shaft. Reinstall the motor, and you're ready to drive.
• Can I use different tooth counts for different driving styles? — Absolutely. Traxxas produces pinion gears in multiple tooth counts (typically 15T, 16T, 17T, 18T, and 19T or higher). Lower tooth counts increase top speed but reduce initial acceleration. Higher tooth counts improve acceleration but reduce top speed. The 18-tooth is the balanced choice; experimentation with alternative counts is common amongst competitive RC drivers who want to fine-tune performance for specific tracks or conditions.
• Is this genuine Traxxas or a third-party product? — This is a genuine Traxxas OEM component manufactured to exact specifications. When you purchase from RC Model Shop, you receive authentic Traxxas products with full warranty support and the assurance that you're getting components designed and tested by Traxxas engineers for optimal compatibility and performance.
