Traxxas 25-Tooth Pinion Gear 32-Pitch 3mm Shaft RC Car Gearing TRX10842

Overview

The Traxxas Gear, 25-T pinion (32-p) (fits 3mm shaft)/ set screw TRX10842 is an essential performance tuning component for RC enthusiasts across the UK who want to optimise their Traxxas models. Whether you're running a high-speed racer or a weekend basher, pinion gears are fundamental to controlling the balance between acceleration and top speed. This 25-tooth pinion gear is specifically engineered to fit 3mm motor shafts and comes complete with a set screw for secure installation, making it the perfect upgrade for fine-tuning your RC car's performance characteristics.

Traxxas pinion gears are manufactured to exacting standards and represent the genuine OEM component that professional racers and casual hobbyists alike depend on for reliability and consistency. If you're looking to adjust your gearing ratio for different running conditions—whether that's tighter technical tracks, open circuits, or off-road terrain—this 25-tooth pinion is an excellent choice. The ability to swap pinion gears gives you control over your vehicle's performance without investing in entirely new drivetrain components, making it one of the most cost-effective upgrades available for any RC car UK enthusiast.

This component is ideal for owners of the Traxxas Mini XRT VXL-3S in any colour variant, and represents genuine Traxxas parts that maintain factory-standard quality and fit. Installing a performance-optimised pinion gear is one of the first steps serious RC hobbyists take when they want to extract maximum performance from their models.

Key Features

• 25-Tooth Design (32-pitch) — The tooth count directly determines your final drive ratio; a 25-tooth pinion offers a specific balance between acceleration and top speed that suits particular running conditions, allowing you to fine-tune performance without replacing your entire drivetrain.
• Compatible with 3mm Motor Shafts — This pinion gear fits standard 3mm diameter motor shafts, ensuring it works with a wide range of Traxxas motors and compatible aftermarket options, making it a versatile upgrade for multiple models.
• Includes Secure Set Screw — The integrated set screw prevents the gear from slipping on the motor shaft during acceleration and braking, maintaining consistent power delivery and eliminating loss of performance due to mechanical slippage.
• 32-Pitch Specification — The 32-pitch measurement defines the gear tooth spacing, ensuring this pinion meshes perfectly with compatible spur gears and maintains smooth, quiet operation with minimal wear.
• Genuine Traxxas OEM Component — As an official Traxxas part, this pinion gear is manufactured to factory specifications and quality standards, guaranteeing reliable performance and longevity compared to generic alternatives.
• Performance Tuning Solution — Changing gear ratios is one of the most effective ways to optimise your RC car's performance for different terrains and driving styles, and this pinion makes that adjustment straightforward and affordable.
• Professional-Grade Engineering — Traxxas gears are used by professional racing teams and competitive drivers who depend on consistent, reliable performance; this same quality is available to all RC enthusiasts.

Technical Performance

The Traxxas 25-tooth pinion gear is engineered from durable materials capable of handling the torque and rotational speeds demanded by electric RC vehicles. With its 32-pitch specification, this component is designed to mesh smoothly with compatible Traxxas spur gears, delivering efficient power transfer from your motor to the wheels whilst minimising noise and mechanical wear. The 3mm bore accommodates standard motor shafts found across most Traxxas electric models, and the included set screw ensures rock-solid retention even under heavy acceleration or demanding terrain. This pinion's tooth count places it in the mid-range of available options, making it suitable for balanced performance across a variety of running conditions. Whether you're driving a Mini XRT VXL-3S or other compatible Traxxas model, this gear maintains the precision engineering that Traxxas is recognised for throughout the RC car UK community. The ability to adjust gear ratios allows drivers to optimise top speed and acceleration independently, a critical consideration for anyone serious about extracting maximum performance from their model. Genuine Traxxas components like this pinion ensure that your drivetrain operates at peak efficiency without the reliability concerns associated with generic or counterfeit alternatives.

Frequently Asked Questions

• What is a pinion gear and why would I need to change it? — A pinion gear connects your motor's output shaft to the spur gear, which drives the wheels. Changing the pinion tooth count alters your vehicle's final gear ratio, which directly affects acceleration and top speed. More teeth provide faster top speed with lower acceleration, whilst fewer teeth deliver quicker acceleration but lower maximum speed. This 25-tooth pinion is a mid-range option suitable for balanced performance.
• Is this gear compatible with my Traxxas model? — This pinion gear is specifically designed for Traxxas models with 3mm motor shafts, including the Traxxas Mini XRT VXL-3S in all colour variants (green, orange, red, and blue). Always consult your model's owner's manual to confirm recommended gearing options before purchasing, as different Traxxas vehicles may have different optimal gear ratios.
• How difficult is it to install this pinion gear? — Installation is straightforward for anyone comfortable with basic RC maintenance. Simply remove your motor, slide off the old pinion gear, clean the shaft, slide on the new 25-tooth pinion, and secure it tightly with the included set screw. The whole process takes just a few minutes and requires only basic tools. If you're unsure about the process, consult your vehicle's manual or ask the team at RC Model Shop for guidance.
• What's the difference between this 25-tooth pinion and other tooth counts? — Pinion gear tooth counts typically range from 16 to 30 teeth. Lower tooth counts (16-18) provide quicker acceleration but lower top speed, whilst higher counts (26-30) deliver higher top speed but slower initial acceleration. This 25-tooth option offers a balanced middle ground suitable for mixed driving conditions and is a popular choice for general-purpose RC car UK use.
• Does this gear work with brushless or brushed motors? — This pinion gear is a mechanical component compatible with both brushless and brushed motors, provided the motor features a standard 3mm output shaft. The gear itself doesn't differentiate between motor types; what matters is the shaft diameter and the vehicle's overall drivetrain compatibility.
• Will changing my pinion gear affect my battery runtime? — Changing your pinion ratio does affect motor efficiency and current draw. A lower tooth count (higher gear ratio) will increase motor speed but also current consumption, potentially reducing battery runtime. Conversely, a higher tooth count might extend runtime but reduce top speed. Experimentation with different pinion ratios is part of optimising your vehicle's performance for your specific driving style and conditions.
