Overview

The ARRMA Steel Pinion Gear 14T Mod1 5mm is an essential spare part for RC enthusiasts who demand durability and reliability from their brushless RC vehicles. Whether you're piloting a high-performance 1/8 scale RC buggy, trophy truck, or speed truck across challenging terrain, having quality spare pinion gears in your RC tool box is crucial for maintaining peak performance. This super-tough steel 14T MOD1 pinion gear is precision-engineered to deliver smooth operation and exceptional longevity, making it the perfect direct replacement for your stock item or an ideal upgrade for demanding RC bashers and racers across the UK.

Designed specifically for ARRMA's range of 6S brushless RC vehicles including the MOJAVE, KRATON, NOTORIOUS, OUTCAST, TALION, and TYPHON models, this pinion gear represents genuine OEM engineering from one of the world's most trusted RC manufacturers. The 14-tooth configuration paired with Mod1 pitch makes this gear compatible with a wide variety of ARRMA's professional-grade brushless RC cars and trucks. If you're running an ARRMA RC vehicle and want to ensure you always have a spare pinion gear ready for track days, weekend bashing sessions, or competitive racing, this is the component you need.

As an authorised ARRMA retailer, RC Model Shop stocks genuine OEM parts that meet the manufacturer's exacting standards. This pinion gear comes from ARRMA's transmission division and has been proven on some of the fastest RC vehicles on the market. Whether you're preparing for an important race meeting, replacing a worn component, or simply maintaining a well-stocked spare parts inventory, the Steel Pinion Gear 14T Mod1 5mm is a wise investment in your RC hobby.

Key Features

• Strong and durable steel construction — Manufactured from high-quality steel, this pinion gear delivers exceptional strength and longevity under extreme RC driving conditions, ensuring it won't strip or fail during aggressive acceleration or high-speed runs that would damage lesser components.
• Precision manufactured tooth profile — Every tooth has been engineered with precision to ensure smooth and efficient meshing with your spur gear, resulting in quieter operation, reduced wear on both gears, and more consistent power delivery to your wheels.
• Double set screw holes — The pinion gear features precision-manufactured double set screw holes that allow secure fastening of set screws either side of the motor shaft, providing extra-secure fitting that prevents slipping or rotation on the shaft during intense driving sessions.
• 5mm motor shaft fitment — Designed specifically for 5mm motor shafts, this 14-tooth gear is compatible with the vast majority of modern brushless RC motors used in ARRMA's 1/8 and 1/7 scale vehicles.
• 14-tooth Mod1 specification — The 14-tooth count combined with Mod1 (Module 1) pitch creates the ideal gear ratio for balancing acceleration and top speed in high-performance brushless RC applications, whether you're racing on track or bashing off-road.
• Genuine OEM ARRMA component — This is the authentic pinion gear used in ARRMA's factory-assembled RTR vehicles, ensuring perfect compatibility and performance matching with your RC car or truck's drivetrain.

Technical Performance

The Steel Pinion Gear 14T Mod1 5mm represents engineering excellence in RC transmission components. Constructed from hardened steel rather than softer materials like plastic or nylon, this pinion gear can withstand the enormous stresses generated by modern brushless RC motors pushing out hundreds of watts. The precision-manufactured tooth profile ensures consistent mesh with your spur gear, eliminating the backlash and noise that come from poorly engineered gears. The double set screw holes are a critical engineering feature that prevents the motor shaft from slipping inside the gear bore during aggressive acceleration, which is especially important when running high-powered brushless motors in 1/8 and 1/7 scale RC vehicles like the ARRMA MOJAVE 6S, KRATON 6S, NOTORIOUS 6S, OUTCAST 6S, TALION 6S, and TYPHON 6S. The 5mm bore specification ensures compatibility with the vast majority of modern brushless RC motors in this scale range. With Mod1 pitch, this 14-tooth configuration delivers a proven balance between acceleration and top speed for competitive racing and recreational bashing alike.

Frequently Asked Questions

• Which ARRMA RC vehicles is this pinion gear compatible with? — This 14T Mod1 steel pinion gear fits ARRMA 6S brushless RC vehicles including the 1/7 scale MOJAVE 6S 4X4 RTR and MOJAVE 6S EXB roller models, plus 1/8 scale options such as the KRATON 6S 4X4 RTR and roller models, NOTORIOUS 6S 4X4 RTR, OUTCAST 6S 4X4 RTR and limited edition variants, TALION 6S 4X4 RTR, and TYPHON 6S 4X4 RTR. It's designed as a direct replacement for the stock pinion gear in these models.
• How often should I replace my RC pinion gear? — With regular use and proper maintenance, a quality steel pinion gear like this one should last hundreds of hours of driving. However, if you notice grinding noises, slipping under acceleration, or visible tooth wear, it's time to replace it. Having a spare pinion gear in your RC tool box means you can swap it out quickly without missing track time.
• Can I use this pinion gear with other RC brands? — This is a Mod1 pitch gear with 5mm bore fitment, so it could theoretically fit other 5mm motor shafts, but ARRMA designs its drivetrain systems as complete units. For guaranteed compatibility and performance, use it only with ARRMA vehicles it's specified for.
• What are the set screws used for? — The two M4x4mm set screws are tightened into the double set screw holes on either side of the motor shaft. They clamp the gear bore securely onto the shaft, preventing any rotation or slipping that could cause loss of power delivery, noise, or gear damage during aggressive acceleration.
• Is this a genuine ARRMA component? — Yes, this is the authentic OEM pinion gear from ARRMA, the genuine manufacturer. The model number AR310475 is the official ARRMA part number, and it's identical to the pinion gear that comes in new ARRMA 6S RTR kits.
• Why choose steel over plastic gears? — Steel gears are significantly more durable than plastic alternatives, especially in the demanding world of brushless RC where motor power outputs are very high. Steel resists stripping, maintains its tooth profile longer, and handles the extreme loads generated during acceleration and high-speed driving far better than softer materials.
