Technical Performance
The Fastrax 48DP 20T Aluminium 7075 Pinion Gear delivers the kind of precision engineering that serious RC enthusiasts demand. Constructed from aircraft-grade aluminium 7075 alloy, this gear combines exceptional strength with minimal weight, creating a component that can handle the demanding stresses of competitive RC driving without failure. The 48-pitch specification and 20-tooth configuration create a specific gear ratio that directly influences your vehicle's acceleration curve and top speed potential. Unlike cheaper steel alternatives, the aluminium construction reduces drivetrain weight, which has measurable benefits for acceleration response and overall vehicle dynamics. The precision-cut teeth ensure smooth, backlash-free engagement with your spur gear, reducing vibration and noise whilst maximising power transfer efficiency from your motor to your wheels. This level of engineering quality explains why Fastrax components are trusted by RC racers and serious hobbyists throughout the UK who understand that drivetrain reliability is fundamental to consistent performance, whether you're competing at the track or bashing across rough terrain in your spare time.

Frequently Asked Questions
- What is a pinion gear and why does it matter in my RC car? — A pinion gear is a small gear that connects your RC motor to your vehicle's main drivetrain spur gear. It's a critical component because its size relative to the spur gear determines your vehicle's gear ratio, which directly affects acceleration, top speed, and overall performance characteristics. Upgrading to a quality pinion gear like this Fastrax model ensures reliable power delivery and smoother operation.
- Will this pinion gear fit my RC car? — The 48DP (48-pitch) specification and 20-tooth design make this gear compatible with a wide range of popular RC platforms that use 48-pitch components. However, you should verify compatibility with your specific RC vehicle's drivetrain before purchase. If you're unsure, our team at RC Model Shop can help you confirm whether this gear will work with your setup.
- What's the advantage of aluminium 7075 over standard steel pinion gears? — Aluminium 7075 is aerospace-grade material that offers superior strength-to-weight ratio compared to standard steel. This means you get a more durable gear that's lighter, improving your vehicle's acceleration and handling whilst reducing drivetrain weight. The enhanced material also resists wear better, extending the lifespan of the component and providing better value over time.
- Can I use this pinion gear for both racing and casual bashing? — Yes, absolutely. Fastrax manufactures components designed for both competitive racing and recreational bashing. The premium aluminium 7075 construction makes this pinion gear suitable for high-performance driving in any context, whether you're competing at your local RC track or enjoying weekend off-road sessions with friends.
- How do I know if my pinion gear needs replacing? — Signs that your pinion gear needs replacement include visible tooth wear or damage, unusual grinding or clicking sounds from your drivetrain, loss of power delivery efficiency, or noticeable backlash when you engage the motor. If you notice any of these symptoms, upgrading to a fresh Fastrax pinion gear is a smart investment in your vehicle's performance.
- Is this a genuine Fastrax product? — Yes, this is an authentic Fastrax component purchased from authorised distributors. RC Model Shop stocks only genuine products from recognised manufacturers, so you can be confident you're getting the real thing with full Fastrax quality assurance.
