Overview
The Fastrax 48DP 17T Aluminium 7075 Pinion Gear is a precision-engineered component designed for RC car enthusiasts across the UK who demand reliability and performance from their upgrades. This lightweight yet robust pinion gear is manufactured from premium 7075 aluminium alloy, a material recognised in the RC hobby for its exceptional strength-to-weight ratio and durability. Whether you're a dedicated racer running competition-grade RC buggies, a weekend basher enjoying high-speed runs, or an experienced hobbyist looking to fine-tune your RC car's performance, this pinion gear delivers the precision engineering you need to keep your vehicle running at peak efficiency.
Pinion gears are critical drivetrain components that directly affect your RC car's acceleration, top speed, and overall handling characteristics. By selecting the right tooth count for your specific application, you can optimise your vehicle's performance profile to match your driving style and terrain. The 48DP (diametral pitch) specification ensures compatibility with a wide range of RC vehicle platforms, making this an essential upgrade or replacement component for your spares box. Fastrax is a respected brand within the UK RC community, known for producing high-quality aftermarket components that enhance reliability and performance across the entire range of RC models.
At RC Model Shop, we stock authentic Fastrax components because we understand that quality upgrades matter. Whether you're looking to replace a worn pinion gear or exploring gear ratio changes to improve your RC car's performance characteristics, this 17-tooth option provides excellent versatility for both track racing and casual recreational driving.
Key Features
- 7075 Aluminium Alloy Construction — The pinion gear is manufactured from premium 7075 aluminium alloy, which is significantly stronger and more durable than standard materials, ensuring long service life even under demanding racing conditions and high-torque situations that would damage lesser alternatives.
- 48DP Specification — The 48 diametral pitch rating ensures this pinion gear is compatible with standard RC drivetrain systems used across numerous popular RC car platforms, making it a reliable upgrade choice for your existing vehicle or a replacement component for your spares collection.
- 17-Tooth Configuration — The 17-tooth count offers a balanced gear ratio that provides good acceleration characteristics whilst maintaining reasonable top speed capabilities, making it suitable for a variety of RC driving conditions from track racing to general recreational use.
- Precision Engineering — Fastrax components are manufactured to exact specifications with tight tolerances, ensuring smooth mesh with your spur gear and reliable power transmission throughout your RC car's drivetrain with minimal noise and vibration.
- Lightweight Design — The aluminium construction keeps unsprung weight to a minimum, which helps maintain responsive handling and improves your RC car's overall agility on both road surfaces and varied terrain common to UK RC tracks.
Technical Performance
The Fastrax 48DP 17T Aluminium 7075 Pinion Gear represents premium quality engineering in a compact drivetrain component. Built from genuine 7075 aluminium alloy, this material selection reflects Fastrax's commitment to durability and performance — 7075 is an aerospace-grade aluminium known for its superior strength characteristics compared to standard materials used in budget alternatives. The 48 diametral pitch specification is the industry standard for modern RC cars, ensuring broad compatibility across electric and nitro-powered vehicles in the UK RC market. The 17-tooth configuration strikes an excellent balance for general-purpose driving, offering sufficient acceleration for circuit racing whilst maintaining respectable top speed performance. Precision manufacturing ensures the gear meshes smoothly with compatible spur gears, minimising drivetrain losses, reducing heat generation, and extending component lifespan. This is the kind of upgrade component that serious RC hobbyists and competitors stock in their spares boxes, knowing that quality pinion gears can make the difference between reliable performance and costly drivetrain failures during important races or recreational sessions.

Frequently Asked Questions
- What does 48DP mean on an RC pinion gear? — DP stands for diametral pitch, which is the standard measurement used to classify gear sizes in RC vehicles. 48DP is the most common specification for modern RC cars, ensuring compatibility with spur gears from leading manufacturers. This measurement defines the tooth spacing and allows you to match pinion and spur gears accurately for optimal drivetrain performance.
- Why would I upgrade to a 7075 aluminium pinion gear? — Standard pinion gears are often made from softer materials that can wear down or strip under high-torque conditions, particularly in competition racing or when using high-powered brushless motors. The 7075 aluminium alloy used in this Fastrax gear offers significantly greater durability, maintaining precise tooth profiles longer and providing more reliable power transmission. This makes it an excellent investment for serious RC enthusiasts who run their vehicles regularly.
- How does a 17-tooth pinion gear affect my RC car's performance? — The tooth count on your pinion gear directly influences your vehicle's gear ratio and thus its acceleration and top speed characteristics. A 17-tooth pinion is considered mid-range and offers a good balance between quick acceleration and respectable top speed. If you find your RC car accelerates too slowly, you might consider a smaller pinion (more teeth provide lower gear ratio and faster acceleration), whilst if it lacks top speed, a larger pinion might suit your needs better — but always check your specific vehicle's compatibility.
- Is this pinion gear suitable for my RC buggy or truck? — The 48DP specification makes this gear compatible with most modern electric and nitro-powered RC buggies, trucks, and cars from UK suppliers. However, always verify that your current spur gear is also 48DP and check your vehicle's manual or manufacturer specifications before purchasing, as compatibility depends on both your pinion and spur gear matching the same pitch specification.
- What is the difference between this and standard steel pinion gears? — Whilst steel pinion gears are common and affordable, the aluminium 7075 construction in this Fastrax gear offers superior strength-to-weight ratio, better heat dissipation properties, and superior durability characteristics. Aluminium gears maintain their precise tooth profiles longer and resist stripping better under high-power applications, making them the choice of serious racers and competitors throughout the UK RC community.
