Overview
The ARRMA 19T Mod1 Pinion Gear is an essential spare part for RC enthusiasts running ARRMA's range of brushless 6S 4WD trucks and buggies. Whether you're a weekend basher pushing your RC car UK setup to the limit or a competitive racer fine-tuning your drivetrain, this precision-engineered steel pinion gear delivers the durability and performance required for extreme RC conditions. As a critical transmission component that directly interfaces with your spur gear, selecting the right pinion size is fundamental to optimising your vehicle's acceleration, top speed and overall performance characteristics.
This 19T configuration strikes an excellent balance between acceleration and top speed, making it a popular choice for drivers seeking versatile performance across various terrain types. The 19-tooth design provides gear ratio flexibility that complements ARRMA's powerful brushless motor systems found in models like the Kraton 6S, Typhon 6S, Outcast 6S, Notorious 6S, Talion 6S and Mojave 6S. Whether you're upgrading from a different tooth count or replacing a worn gear, this genuine ARRMA component ensures compatibility and reliability with your existing setup.
ARRMA's commitment to precision manufacturing means every tooth is cut to exacting standards, guaranteeing smooth mesh engagement with your spur gear and reliable power delivery under demanding conditions. For RC car enthusiasts throughout the UK, having spare pinion gears in your toolbox is simply good practice—gear damage from over-driving or debris impact can happen in seconds, but a replacement pinion keeps you racing within minutes.
Key Features
- Solid Steel Construction — Manufactured from hardened steel, this pinion gear withstands the extreme forces generated by high-torque brushless motors in competitive and casual RC environments, ensuring consistent performance without premature tooth wear or breakage.
- Precision-Machined Teeth — Each tooth is manufactured with tight tolerances to ensure perfect mesh alignment with your spur gear, reducing noise, vibration and drivetrain stress while maximising power transmission efficiency.
- Precision-Engineered Bore Threading — The bore is machined with precision threading that accepts the included steel securing screw, providing a secure and repeatable mounting that prevents slippage during hard acceleration or extreme cornering.
- 19-Tooth Configuration — This mid-range tooth count delivers an excellent balance between acceleration and top speed, making it suitable for a wide variety of terrain types and driving styles without sacrificing performance in either direction.
- Mod1 Gear Pitch — The Mod1 (Module 1) specification ensures compatibility with ARRMA's spur gears and transmission systems, guaranteeing proper engagement and reliable operation across the entire ARRMA 6S brushless lineup.
- Includes Mounting Hardware — Each gear comes with one steel securing screw, eliminating the need to source additional fasteners and ensuring you have everything required for immediate installation.
Technical Performance
The 19T Mod1 pinion gear is engineered to deliver exceptional durability and performance across ARRMA's full range of 6S brushless RC vehicles. The solid steel construction provides superior strength compared to lighter alternative materials, absorbing impact forces and resisting the repetitive shear stresses generated by continuous acceleration and deceleration cycles. The precision-machined tooth profile ensures minimal backlash when engaged with your spur gear, which translates to more responsive steering input, better traction control and improved acceleration characteristics. This component is rated for use across the entire ARRMA 6S platform, including the 1/7 Mojave 6S, 1/8 Kraton 6S, 1/8 Typhon 6S, 1/8 Outcast 6S, 1/8 Notorious 6S and 1/8 Talion 6S models. The 19-tooth count provides a gear ratio that works exceptionally well with ARRMA's high-torque brushless motors, offering drivers the flexibility to tune their vehicle's performance characteristics by combining this pinion with different spur gear sizes to achieve their desired balance of acceleration and top speed.

Frequently Asked Questions
- What ARRMA models is the 19T Mod1 pinion gear compatible with? — This pinion gear is designed for ARRMA's 6S brushless models, including the Mojave 6S 4WD RTR, Kraton 6S 4WD RTR, Kraton 6S EXB Roller, Typhon 6S 4WD RTR, Outcast 6S 4WD RTR, Outcast 6S Limited Edition, Notorious 6S 4WD RTR and Talion 6S 4WD RTR. Always verify your specific model's transmission requirements before purchasing.
- What is the difference between 19T and other pinion gear sizes? — Pinion gear tooth count directly affects your vehicle's gear ratio. Lower tooth counts (12T-15T) provide more aggressive acceleration but lower top speed, whilst higher counts (20T-23T) favour top speed over acceleration. The 19T option strikes a balanced middle ground, making it ideal for drivers wanting versatile performance without extreme bias toward either characteristic.
- How often will I need to replace the pinion gear? — Under normal driving conditions, a quality steel pinion gear like this will last for many hours of use. However, accidents, collisions and running over debris can cause immediate damage. Additionally, excessive pinion wear occurs if your spur gear is worn, so inspect both components together during maintenance to prevent premature failure.
- Is this suitable for beginners? — Yes, the 19T Mod1 pinion gear is an excellent choice for drivers at all experience levels. It provides balanced performance that doesn't demand extreme driving techniques to perform well, making it ideal for newer RC enthusiasts learning vehicle setup and tuning. The included steel screw simplifies installation, and compatible ARRMA RTR models include comprehensive instructions.
- Why should I buy genuine ARRMA pinion gears instead of aftermarket alternatives? — Genuine ARRMA components are engineered to exact specifications that match your vehicle's transmission system, ensuring proper tooth engagement and maximum durability. OEM gears undergo rigorous quality testing and are manufactured to tolerances that guarantee compatibility with ARRMA spur gears and motor systems, whereas aftermarket alternatives may introduce fitment issues, noise and premature wear.
