Key Features
- 48 Diametral Pitch (48Dp) Specification — The 48 diametral pitch rating indicates this is a precision-cut gear designed for smooth, efficient meshing with compatible spur gears, ensuring reliable power transmission and minimising noise during operation, which is particularly important for competitive racing where mechanical consistency matters.
- 28-Tooth Configuration — The 28-tooth count is a popular choice for RC cars as it balances acceleration with top speed, allowing you to customise your vehicle's performance profile depending on whether you prioritise quick getaway speed or maximum velocity on open terrain.
- Aluminium 7075 Construction — This premium aluminium alloy offers an exceptional strength-to-weight ratio, providing durability that can withstand the stresses of high-performance driving whilst remaining lightweight enough to not negatively impact your RC car's weight distribution and handling characteristics.
- Direct Replacement Part — This pinion gear is designed as a direct replacement component, making it simple to install into compatible RC car models without requiring additional modifications or adapters, saving time and frustration during maintenance or upgrades.
- Compatible with Multiple RC Platforms — The standardised 48Dp specification means this gear works across a wide range of RC vehicles from different manufacturers, making it a versatile addition to any RC hobbyist's spare parts collection.
Technical Performance
The Fastrax 48Dp 28T Aluminium 7075 Pinion Gear represents precision engineering at its finest for RC car enthusiasts. Constructed from 7075 aluminium alloy, one of the strongest aluminium alloys available in the market, this pinion gear combines exceptional durability with minimal weight, a critical balance in high-performance RC applications. The 48 diametral pitch specification ensures tooth profiles that are precisely cut to ISO standards, allowing for smooth, backlash-free meshing with compatible spur gears. This precision is essential for maintaining consistent power delivery and reducing mechanical losses that can rob your RC car of performance. At 28 teeth, this pinion provides an effective gear ratio option that suits a variety of driving styles and terrain types, from tight technical courses where acceleration is paramount to more open areas where sustained top speed becomes important. The engineering quality evident in this component reflects Fastrax's commitment to manufacturing standards that satisfy both casual RC car enthusiasts and serious competitors who demand reliability they can trust lap after lap. Installation is straightforward, requiring only basic tools and mechanical knowledge, making this an accessible upgrade or maintenance item for anyone with experience adjusting their RC car setup.

Frequently Asked Questions
- What vehicles is the Fastrax 48Dp 28T pinion gear compatible with? — This 48 diametral pitch gear is designed to work with numerous RC car models that accept standard 48Dp pinions. The compatibility depends on your vehicle's gearbox specifications and motor shaft type. We recommend checking your RC car's documentation or contacting our team at RC Model Shop to confirm compatibility with your specific model before purchasing.
- Why would I need to replace or upgrade my pinion gear? — Pinion gears wear over time through normal use, and replacing a worn gear restores smooth power delivery and prevents noise and vibration. Additionally, upgrading to a different tooth count adjusts your vehicle's acceleration and speed balance. If you've noticed grinding sounds or inconsistent acceleration, it's time to inspect your pinion gear.
- How does the 28-tooth configuration affect my RC car's performance? — The 28-tooth pinion offers a balanced approach to RC car performance. Compared to lower tooth counts (which favour speed), this configuration provides strong acceleration whilst still maintaining respectable top speed. Compared to higher tooth counts (which favour acceleration), it allows for greater maximum velocity. Your choice depends on whether you prioritise quick acceleration or sustained top speed.
- What makes 7075 aluminium better than standard aluminium for pinion gears? — Aluminium 7075 is one of the strongest aluminium alloys available, offering superior strength compared to standard 6061 or 6063 aluminium. This means your pinion gear can withstand greater stresses without stripping, warping, or cracking, extending component lifespan and providing more reliable performance during demanding driving sessions.
- Is this suitable for beginners? — Yes, this pinion gear is suitable for beginners, though gear replacement requires basic mechanical knowledge. If you're new to RC car maintenance, we recommend watching installation tutorials or visiting our store in Walsall where our team can provide guidance. The actual installation process is straightforward once you understand your vehicle's gearbox design.
- What is the difference between 48Dp and other diametral pitch specifications? — Diametral pitch (Dp) refers to the number of teeth per unit of diameter. Higher numbers like 48Dp have smaller, finer teeth, whilst lower numbers have larger teeth. 48Dp is a standard specification offering good durability and smooth operation for most RC cars. Other common options include 32Dp and 64Dp, which suit different applications.
