Overview
The Traxxas Spur 56-tooth (0.8 metric pitch, compatible with 32-pitch) TRX3957 is an essential performance tuning component for RC enthusiasts across the UK who want to optimise their Traxxas RC models. Whether you're running a Traxxas Slash, short course truck, or other compatible model, this precision-engineered spur gear allows you to fine-tune your vehicle's performance characteristics to suit different running conditions and your personal driving preferences. As a dedicated RC car UK retailer, we understand that gearing plays a crucial role in how your ready to run RC performs, and this genuine Traxxas spare part is the professional choice for competitors and hobbyists alike.
Spur gears are fundamental components in the drivetrain system of any RC vehicle, and changing gear ratios is one of the most effective ways to balance acceleration against top speed. The 56-tooth configuration offers a specific gear ratio that will transform how your brushless RC truck or short course vehicle behaves on the track or off-road. By adjusting your spur gear selection, you gain the ability to optimise performance for tight technical sections, high-speed open areas, or mixed terrain without having to buy a completely new RC model. This flexibility makes gearing upgrades like the TRX3957 one of the smartest investments a UK RC enthusiast can make.
Built to Traxxas' renowned standards of quality and durability, this spur gear is manufactured to precise tolerances and engineered to withstand the rigours of competitive racing and weekend bashing alike. The 0.8 metric pitch specification (compatible with 32-pitch) ensures perfect meshing compatibility with standard Traxxas pinion gears and drivetrain components, giving you confidence that this is a genuine, properly engineered replacement part that will integrate seamlessly into your RC setup.

Technical Performance
The Traxxas Spur 56-tooth TRX3957 represents precision engineering designed for the demanding world of RC motorsport. Operating at 0.8 metric pitch (32-pitch specification), this spur gear is engineered to mesh perfectly with complementary pinion gears in your drivetrain, delivering smooth power transmission and efficient performance delivery. The 56-tooth configuration places this gear at a specific point in the acceleration-to-top-speed spectrum; compared to smaller tooth counts, a 56-tooth spur delivers a higher gear ratio that emphasises acceleration and torque delivery whilst moderating maximum top speed. This makes it ideal for technical track sections, tight turning areas, or situations where responsive handling is more valuable than outright speed. The gear is manufactured from durable materials selected for their ability to withstand repeated meshing cycles, shock loads, and the sustained power delivery of brushless RC motors without tooth stripping or degradation. When used with standard Traxxas brushless systems and compatible battery configurations (consult your model's manual for specific power recommendations), this spur gear provides dependable performance across a wide range of driving conditions. The engineering behind this component reflects Traxxas' commitment to quality and reliability, making it a trusted choice among UK RC enthusiasts who demand genuine parts that deliver consistent results.

Frequently Asked Questions
- What models is the Traxxas TRX3957 56-tooth spur gear compatible with? — This gear is compatible with a range of Traxxas models including the Traxxas Slash Ultimate 4x4 VXL 1:10 4WD Brushless Short Course Truck, and the Traxxas Slash VXL 1/10 4x4 RTR in Blue, Green, Orange and Red variants. Always consult your specific model's owner's manual to confirm compatibility and gearing recommendations.
- What is the difference between a 56-tooth spur and other tooth counts? — Spur gear tooth count directly affects your vehicle's gear ratio and performance characteristics. A 56-tooth spur provides a higher gear ratio than smaller tooth counts (such as 48-tooth), emphasising acceleration and torque response whilst reducing top speed. This makes it ideal for technical tracks and slower, more technical courses. Conversely, smaller tooth count spurs (lower ratio) favour higher top speeds with slightly reduced acceleration.
- Is this suitable for both racing and casual bashing? — Yes, absolutely. The TRX3957 is a genuine Traxxas component engineered for reliability and durability. It works equally well whether you're competing in organised RC racing events or enjoying casual weekend bashing with friends. The key is selecting the tooth count that matches your preferred driving style and course characteristics.
- How do I install this spur gear? — Installation requires access to your vehicle's drivetrain and removal of the existing spur gear. This is a straightforward procedure for anyone with basic RC maintenance knowledge. Your model's owner's manual contains detailed installation instructions and torque specifications. If you're new to RC maintenance, our knowledgeable team at RC Model Shop can offer guidance and support.
- Will this work with my current brushless system? — This spur gear is compatible with standard Traxxas brushless systems. The gear itself is a passive mechanical component that works with any compatible pinion gear and brushless motor setup. Consult your model's manual for specific recommendations on motor type, KV rating, and battery compatibility for your particular vehicle.
- What does the 0.8 metric pitch specification mean? — Pitch refers to the spacing and size of gear teeth. The 0.8 metric pitch (also described as 32-pitch) is a standard specification used across many Traxxas models. This specification ensures that the spur gear teeth mesh perfectly with compatible pinion gears for smooth, efficient power transmission. Using gears with mismatched pitch specifications can result in poor meshing, noise, and potential damage.
- Can I use this to upgrade my older Traxxas model? — This 56-tooth spur is compatible with several Traxxas models, particularly Slash variants. However, older models may use different pitch specifications or drivetrain designs. Always check your vehicle's manual or contact our expert team to confirm compatibility before purchasing. We're here to help ensure you get the right parts for your specific RC model.
