Overview
The Fastrax 48DP 31T Aluminium 7075 Pinion Gear (FAST48-31) is a precision-engineered component designed for RC car enthusiasts across the UK who demand reliability and performance from their setup. Whether you're running a competitive RC buggy, truggy, or general off-road vehicle, this pinion gear delivers the consistent meshing and durability that serious RC hobbyists expect. Manufactured from premium 7075 aluminium alloy, this gear represents Fastrax's commitment to quality engineering for the RC car UK market.
Pinion gears are one of the most critical drivetrain components in any RC vehicle, directly affecting acceleration, top speed, and overall powertrain efficiency. The 48-pitch (48DP) specification means this gear is designed to work with compatible spur gears to transfer power smoothly from your motor to the wheels. A 31-tooth configuration offers a specific gear ratio that enthusiasts select based on their track conditions, motor power, and desired performance characteristics. Whether you're looking to fine-tune your ready to run RC car or building a custom setup, having the right pinion gear is essential for optimal performance.
RC Model Shop stocks the Fastrax 48DP 31T Aluminium 7075 Pinion Gear as part of our comprehensive range of replacement and upgrade parts for RC vehicles.

Technical Performance
The Fastrax 48DP 31T Aluminium 7075 Pinion Gear represents a fundamental component in RC drivetrain engineering. At 48 diametral pitch (48DP), this gear is designed to mesh seamlessly with corresponding spur gears in the 48DP standard, which is widely adopted across the RC industry for 1/10 scale and other popular RC vehicles. The 31-tooth count determines the gear ratio when paired with your spur gear, directly influencing how your motor's power is translated into vehicle speed and acceleration. Aluminium 7075 is an aerospace-grade material that offers superior strength compared to standard aluminium or nylon alternatives, which is why discerning RC enthusiasts choose it for mission-critical drivetrain components. The precision machining ensures that gear teeth are cut to exact specifications, preventing binding, noise, and power loss during operation. Whether you're running a brushless motor pushing serious power or a standard brushed motor setup, this pinion gear will handle the torque transfer efficiently. For RC car enthusiasts in the UK who understand that drivetrain performance directly impacts overall vehicle handling and speed delivery, investing in a quality pinion gear like this Fastrax component is a smart decision that will improve your RC experience and reduce downtime due to gear failure.

Frequently Asked Questions
- What is a pinion gear and why do I need it in my RC car? — A pinion gear is the small gear attached to your motor shaft that meshes with the larger spur gear connected to your drivetrain. It's essential because it transfers power from your motor to the wheels while establishing the overall gear ratio that determines your vehicle's acceleration and top speed characteristics. Without a properly functioning pinion gear, your RC car simply won't operate.
- How do I know if 31T is the right tooth count for me? — The ideal tooth count depends on several factors including your motor KV rating, battery voltage, desired top speed, track type, and driving style. Lower tooth counts (like 27-29T) provide more acceleration but lower top speed, whilst higher counts (like 33-35T) offer more top speed but require more motor power to accelerate. Many competitive RC drivers carry multiple pinion gears to test different ratios for different tracks.
- Why is 7075 aluminium better than standard aluminium or plastic? — 7075 aluminium is an aerospace-grade material that is significantly stronger and more rigid than standard aluminium or nylon alternatives. This means it resists stripping, flexing, and breaking under the extreme forces generated by powerful RC motors. For serious RC enthusiasts, the durability and performance consistency of 7075 pinion gears justify the investment.
- Is this gear compatible with my RC vehicle? — This is a 48DP pinion gear, so it will work with any RC vehicle designed for 48DP drivetrain components, which includes most 1/10 scale buggies, trucks, and truggy vehicles from manufacturers like Traxxas, Losi, ARRMA, Team Associated, and others. However, always verify your vehicle's specifications to ensure 48DP compatibility before purchasing.
- Can I use this with any motor? — This pinion gear can be used with any motor system (brushless or brushed) that is compatible with 48DP drivetrain standards, provided your motor shaft fits the pinion gear's bore. The gear itself is motor-agnostic—it simply transfers the power being delivered.
- How often should I replace my pinion gear? — With proper maintenance and appropriate gear ratios for your motor power, a quality 7075 aluminium pinion gear like this Fastrax component can last through hundreds of driving hours. You'll need to replace it if you notice stripped teeth, visible cracks, or if meshing becomes noisy or inefficient.
