Key Features

• 48-Pitch Specification — This 48-pitch (48DP) rating ensures precision meshing with compatible spur gears, delivering smooth power transfer with minimal backlash and wear, which is critical for maintaining consistent acceleration and top-end speed in competitive racing environments.
• 15-Tooth Configuration — The 15-tooth count provides the optimal balance between acceleration and top speed, making this gear suitable for a wide variety of track conditions, terrain types, and racing disciplines from tight technical circuits to flowing high-speed layouts.
• 7075 Aluminium Alloy Construction — Aircraft-grade 7075 aluminium is selected for its exceptional strength, rigidity, and resistance to wear, ensuring your pinion gear maintains its precision tolerances throughout extended racing seasons and maintains engagement with your spur gear without deformation or tooth wear.
• Superior Material Quality — The choice of 7075 aluminium over standard alloys means this gear weighs less than comparable steel alternatives whilst offering significantly greater durability and longer operational lifespan, reducing maintenance intervals and component replacement costs.
• Precision Manufacturing — Each tooth is CNC-machined to exacting tolerances, ensuring perfect meshing characteristics and compatibility with OEM and aftermarket spur gears, which translates to smoother acceleration, reduced drivetrain noise, and more efficient power delivery to the wheels.
• Direct Replacement Compatibility — The Fastrax 48DP 15T pinion gear is engineered as a direct upgrade for countless popular RC platforms, allowing you to increase performance without requiring additional modifications or chassis adjustments.

Technical Performance

The Fastrax 48DP 15T Aluminium 7075 Pinion Gear represents the intersection of materials science and precision engineering that serious RC car enthusiasts demand. The 7075 aluminium alloy used in its construction is the same high-strength material employed in aerospace applications, offering a hardness and durability profile that far exceeds standard aluminium gears found on budget RC vehicles and entry-level kits. The 48-pitch specification ensures micrometre-level accuracy in tooth spacing and profile, which means when this pinion gear engages with a compatible spur gear, the power transfer is smooth, efficient, and virtually free from the backlash and slop that degrades handling and acceleration response in lesser components. The 15-tooth configuration strikes an intelligent balance in the gearing equation: it provides sufficient mechanical advantage for rapid acceleration off the line whilst maintaining enough top-end speed capability for high-velocity running on open, flowing track sections. This makes it an exceptionally versatile choice whether you're running a competitive off-road buggy on a technical grass track, an on-road touring car at a dedicated RC racing circuit, or a bashing truck on mixed terrain. The lightweight nature of aluminium construction means the pinion gear contributes minimal rotational mass to your drivetrain, allowing your motor to reach peak RPM more quickly and respond more dynamically to throttle inputs. For competitive racers and serious hobbyists running brushless motor systems with modern ESCs and LiPo battery technology, this pinion gear will reliably handle the extreme torque loads and RPM demands of contemporary high-performance RC vehicles, maintaining its precision engagement and tooth integrity season after season.

Frequently Asked Questions

• What does the 48DP specification mean on this Fastrax pinion gear? — The 48DP designation refers to the diametral pitch (DP) of the gear, which defines the tooth size and spacing. 48-pitch gears have smaller, more closely-spaced teeth than lower-pitch alternatives, enabling finer control over gearing ratios and smoother meshing characteristics. This is the industry standard for high-performance RC cars and trucks available in the UK.
• Will this 15-tooth pinion gear fit my RC car? — The Fastrax 48DP 15T pinion gear is engineered for compatibility with standard 48-pitch spur gears found on most popular RC platforms including Traxxas, Team Associated, Losi, ARRMA and other major brands. However, you should verify your vehicle uses a 48-pitch drivetrain system before purchasing, as some models employ different pitch specifications. Contact our team at RC Model Shop if you're uncertain about compatibility with your specific model.
• What is the advantage of 7075 aluminium compared to standard gears? — 7075 aluminium is an aerospace-grade alloy that offers dramatically superior strength, hardness, and wear resistance compared to standard aluminium or mild steel gears. This means the Fastrax pinion gear will maintain its precision tolerances for far longer, resist tooth stripping under extreme torque loads, and require significantly less maintenance throughout its operational lifespan, ultimately saving you money on replacement components.
• Is the 15-tooth configuration suitable for off-road or on-road racing? — The 15-tooth pinion gear is remarkably versatile and performs excellently in both applications. For off-road buggies and trucks on grass or dirt circuits, it provides strong acceleration for conquering obstacles and loose terrain. For on-road touring cars, it balances acceleration with sufficient top-speed capability for flowing race tracks. This makes it an ideal choice if you run multiple vehicle types or frequently switch between different racing venues.
• How do I know if my existing pinion gear is worn and needs replacement? — Signs of pinion gear wear include audible grinding or whining noises during acceleration, visible tooth damage or flattening when inspected closely, difficulty maintaining consistent gear engagement, or a feeling of hesitation during throttle application. If you've been racing competitively for a full season or regularly bash your RC vehicle, replacing your pinion gear with this Fastrax component is a sensible preventative maintenance step that will restore crisp throttle response and eliminate potential drivetrain inefficiency.
• Can I use this pinion gear with both brushless and brushed motors? — Yes, the Fastrax 48DP 15T pinion gear is compatible with both brushless and brushed motor systems, as long as your vehicle uses a standard 48-pitch drivetrain architecture. The gear itself is motor-agnostic; what matters is the spur gear and chassis configuration. Many competitive RC enthusiasts upgrade from brushed to brushless motor systems whilst retaining the same chassis and drivetrain, making this gear an excellent upgrade component for such transitions.
• What maintenance does this pinion gear require? — The 7075 aluminium construction requires minimal maintenance compared to lower-quality alternatives. After each racing session or bashing day, wipe the gear clean of dirt and debris, inspect for any visible damage, and ensure the bearing surfaces remain lubricated. A light machine oil or dedicated RC gear lubricant applied sparingly to the bearing surfaces will ensure smooth operation. Unlike steel gears that require aggressive cleaning to prevent rust, this aluminium gear resists corrosion and requires only basic care.
