This genuine ARRMA part ensures compatibility and reliability with your RC setup, making it an ideal choice for anyone looking to maintain or upgrade their electric RC car.
Pinion gears are critical drivetrain components that work in conjunction with your RC car's spur gear to transfer power from the motor to the wheels. Choosing the correct pinion gear specification is fundamental to achieving optimal performance, whether you are chasing top speed on a straight track, seeking better acceleration off the line, or looking for improved overall handling characteristics. The ARRMA 16T Mod1 Safe-D8 Pinion Gear is engineered to deliver consistent, reliable performance and is trusted by RC enthusiasts across the United Kingdom who demand quality and precision in their RC hobby equipment.
As an authorised ARRMA dealer, RC Model Shop stocks genuine original parts to keep your RC vehicles running at their best. This pinion gear represents ARRMA's commitment to providing aftermarket support and replacement components that meet the exact specifications your RC car requires for peak performance.
Key Features
- Mod 1 Gear Pitch — The Mod 1 specification indicates the gear module, which defines the size and tooth pitch of the gear. This standardised specification ensures precise meshing with your spur gear and consistent power transmission efficiency, which is critical for smooth acceleration and reliable performance across all driving conditions.
- 16-Tooth Configuration — This pinion gear features 16 teeth, a specification that directly impacts your RC car's final drive ratio and overall speed characteristics. The tooth count you choose will affect both acceleration and top speed, making this an important tuning variable for RC enthusiasts who want to dial in their vehicle's performance for specific track conditions or driving styles.
- Safe-D8 Bore — The Safe-D8 bore design ensures secure, reliable attachment to your motor shaft with minimal play or slippage during operation. This precision fit is essential for maintaining consistent power delivery and preventing the kind of drivetrain issues that can occur with loose or poorly fitting components, which would compromise both performance and reliability.
- Genuine ARRMA Component — As an official ARRMA part, this pinion gear is manufactured to exact OEM specifications and quality standards, ensuring perfect compatibility with your ARRMA RC vehicle and delivering the performance characteristics ARRMA engineers intended for your model.
Technical Performance
The ARRMA 16T Mod1 Safe-D8 Pinion Gear is engineered with precision manufacturing tolerances that ensure smooth meshing with spur gears and consistent power delivery throughout operation. The Mod 1 gear specification defines the relationship between tooth size and pitch diameter, creating a standardised interface that works reliably with compatible ARRMA drivetrain components. The 16-tooth count represents a common tuning option for ARRMA vehicles, offering a balance between acceleration and top speed that suits a wide range of driving scenarios and skill levels. The Safe-D8 bore system provides a secure connection to your motor shaft, eliminating the wobble and inconsistency that can result from loose-fitting components. This precision engineering means you are not just replacing a worn gear—you are reinstalling a component that meets ARRMA's exacting quality standards and will perform exactly as your RC car's designers intended. Whether you are using this pinion gear on a ready to run RC model or as part of a race kit setup, the engineering quality ensures reliable performance and longevity.

Frequently Asked Questions
- What is a pinion gear and why do I need to replace it? — A pinion gear is a small toothed wheel on your RC car's motor shaft that meshes with the spur gear to transfer power to the wheels. Over time, pinion gears can wear down, strip teeth, or become damaged through normal use, especially in competitive racing or heavy bashing scenarios. Replacing a worn pinion gear restores proper drivetrain function and prevents further damage to your RC car's transmission system.
- How do I know if the 16-tooth pinion is right for my ARRMA RC car? — Pinion gear tooth count is a tuning variable that affects your vehicle's acceleration and top speed. Smaller tooth counts like 15T will give you higher top speed but slower acceleration, while larger tooth counts provide quicker acceleration but lower top speed. The 16T specification represents a middle ground suitable for general purpose driving, but your specific ARRMA model documentation will indicate the recommended tooth counts for your vehicle.
- Is the Safe-D8 bore compatible with my motor? — The Safe-D8 bore is ARRMA's proprietary shaft fitment system designed to work with ARRMA motors and motor shafts. Before ordering, verify that your vehicle uses a Safe-D8 bore specification by checking your model's documentation or the existing pinion gear on your RC car.
- Where can I find my exact model specifications? — The part number Z-ARA311036 uniquely identifies this component. Your ARRMA vehicle's manual or the packaging of your RC car should specify which pinion gear tooth count and bore type your model requires, ensuring you order the correct replacement part.
- Can I use this pinion gear on other RC brands? — This is an ARRMA-specific component engineered for ARRMA vehicles. Using it on other RC brands may result in poor fitment or performance issues. Always verify compatibility with your specific RC car model before installation.
