Overview
The Traxxas Gear, 23-T pinion (32-p) (fits 3mm shaft) with set screw is an essential performance tuning component for RC enthusiasts across the UK who want to optimise their Traxxas models. Whether you're a competitive racer, weekend basher, or serious RC car UK hobbyist, pinion gears are the foundation of fine-tuning your vehicle's acceleration and top speed characteristics. This genuine Traxxas pinion gear allows you to adjust your gear ratio to match different running conditions, track layouts, and driving styles—a crucial capability for anyone serious about getting the best performance from their RC model.
Designed specifically for 3mm motor shafts, this 23-tooth pinion gear operates at 32-pitch and includes a set screw for secure installation. It's compatible with steel spur gears, making it a versatile upgrade for a range of Traxxas models including the popular Mini XRT VXL-3S range. Unlike generic aftermarket alternatives, this is genuine Traxxas engineering backed by decades of RC innovation. For anyone running brushless RC cars or upgrading their existing setup, understanding and adjusting your pinion gear ratio is fundamental to achieving optimal performance.
Traxxas pinion gears are renowned for their precision manufacturing and durability. By selecting the correct tooth count for your specific model and driving conditions, you can strike the perfect balance between raw acceleration and maximum velocity. Whether you need more punch off the line for tight technical courses or more top-end speed for open tracks, this 23-tooth option provides a proven solution trusted by RC racers and enthusiasts throughout the UK.
Key Features
- 23-Tooth Design — This specific tooth count is engineered to work as a mid-range gearing option, providing a balanced compromise between acceleration and top speed that suits a variety of running conditions and track types across UK RC racing venues.
- 32-Pitch Specification — The 32-pitch (32dp) specification ensures compatibility with 32-pitch spur gears, which is a standard in the RC industry and allows for seamless integration with your existing Traxxas drivetrain components.
- 3mm Motor Shaft Bore — Precision-engineered to fit 3mm motor shafts perfectly, eliminating play and ensuring reliable power transmission from your brushless motor to the drivetrain with zero slippage.
- Included Set Screw — The integrated set screw provides a secure, repeatable method of fastening the pinion gear to your motor shaft, preventing accidental slipping during high-speed runs or aggressive acceleration.
- Steel Spur Gear Compatible — This pinion gear is specifically designed for use with steel spur gears, offering the durability and longevity that serious RC enthusiasts demand from their drivetrain components.
- Genuine Traxxas Manufacturing — As an authentic Traxxas component, this pinion gear meets the exact same quality and tolerance standards as the gears originally supplied with your RC model, guaranteeing fit and performance.
- Performance Tuning Flexibility — By offering multiple tooth count options (including 19T, 25T, and 29T variants), Traxxas enables you to fine-tune your vehicle's characteristics to match your specific needs and preferences.
Technical Performance
This pinion gear is a precision-engineered drivetrain component manufactured to exacting Traxxas standards. The 23-tooth configuration at 32-pitch delivers a mid-range gear ratio that balances acceleration and top speed—ideal for drivers who want versatility across different track conditions without constantly swapping gears. The 3mm bore is machined to tight tolerances to ensure perfect fit on motor shafts, eliminating the gear slop that can develop over time with inferior aftermarket alternatives. Built from durable materials engineered to withstand the torque loads of brushless motors, this pinion gear performs reliably whether you're running on carpet, tarmac, or off-road terrain. The included set screw provides a positive mechanical lock that prevents gear slip under heavy acceleration or competitive racing conditions. For RC car enthusiasts in the UK looking to optimise their Traxxas models, selecting the correct pinion gear tooth count is one of the most effective performance tuning modifications you can make, directly affecting throttle response, mid-range power delivery, and top-end velocity. This component is fully compatible with the Traxxas Mini XRT VXL-3S available in green, orange, red, and blue variants, as well as other comparable Traxxas models with 3mm motor shafts.

Frequently Asked Questions
- Will this pinion gear fit my Traxxas RC model? — This 23-tooth pinion gear is specifically engineered for Traxxas models with 3mm motor shafts. It is confirmed compatible with the Traxxas Mini XRT VXL-3S range available in all colour variants (green, orange, red, and blue). Always consult your specific model's owner's manual to confirm motor shaft size before purchasing, as different Traxxas models use different shaft diameters.
- What is the difference between tooth counts like 19T, 23T, 25T, and 29T? — Lower tooth counts (like 19T) create a lower gear ratio, delivering more acceleration and torque but lower top speed—ideal for tight technical courses and acceleration-focused driving. Higher tooth counts (like 29T) create a higher gear ratio, enabling greater top speed but requiring more power to accelerate—better suited for open tracks and high-speed runs. The 23-tooth option sits in the middle, offering balanced performance across varying conditions, making it a versatile choice for drivers who want a single setup that works well everywhere.
- Why would I change my pinion gear ratio? — Changing your pinion gear tooth count is one of the most effective performance tuning modifications available to RC enthusiasts. Different track layouts, surfaces, and weather conditions favour different gear ratios. Running too low a ratio wastes top speed; running too high drains your battery and kills acceleration. By selecting the optimal pinion gear for your specific conditions, you can dramatically improve lap times, battery efficiency, and overall drivability.
- Is this compatible with all steel spur gears? — This pinion gear is designed for use with 32-pitch (32dp) steel spur gears. It is not compatible with spur gears of different pitch specifications. The 32-pitch standard is common across many Traxxas models, but always verify your spur gear pitch before purchasing to ensure compatibility.
- Will this work with brushless motors? — Yes, this pinion gear is fully compatible with brushless RC motors featuring 3mm shafts. Brushless motors deliver significantly more power than brushed alternatives, making proper drivetrain selection—including pinion gear ratio—even more critical to vehicle performance and longevity.
- How do I install the set screw? — Slide the pinion gear onto your 3mm motor shaft and align it with the slot provided for the set screw. Insert the set screw through the gear bore into the motor shaft and tighten with an appropriate hex driver. Do not over-tighten, as this can strip the motor shaft threads. Consult your model's owner's manual for specific torque recommendations if available.
- What is the advantage of genuine Traxxas gears over generic alternatives? — Genuine Traxxas components are manufactured to precise tolerances and material specifications that match the engineering of your vehicle. Aftermarket gears may have dimensional variations that cause premature wear, noise, or even drivetrain failure. Investing in genuine components ensures reliable performance and longevity.
