Key Features
- Strong Steel Construction — This spur gear is manufactured from high-quality steel that provides exceptional durability and longevity, ensuring it maintains its structural integrity through countless hours of bashing, racing and high-powered driving in all conditions. Steel offers superior wear resistance compared to plastic alternatives, meaning your gear will maintain its tooth profile for extended periods without degradation.
- Precision Manufactured Tooth Configuration — Every tooth on this 47T spur gear is manufactured to exact specifications using advanced precision machining techniques. This precise engineering ensures smooth power transfer from your brushless motor to the transmission, eliminating vibration and noise whilst delivering consistent, reliable performance lap after lap and session after session.
- Engineered for Brushless Motors — The ARRMA Spur Gear 47T is specifically designed to work with large-scale brushless motors, which deliver significantly more power than brushed alternatives. The gear's tooth geometry and material composition are optimised to handle the intense torque and rapid acceleration characteristics of brushless drivetrain systems without slipping, stripping or premature wear.
- 47-Tooth Configuration — The 47-tooth count is specifically matched to the Kraton 8S and Outcast 8S models, ensuring perfect compatibility and optimal gearing ratios. This tooth count is calibrated by ARRMA engineers to deliver the ideal balance between acceleration and top speed for these monster truck platforms.
- 1.0 Module Gear Pitch — The 1.0 module specification indicates the pitch and size of the gear teeth, which directly affects meshing with the pinion gear. This standard module measurement ensures proper engagement and smooth operation when paired with the factory pinion gear on your Kraton or Outcast.
Technical Performance
The ARRMA Spur Gear 47T Z-ARA310920 represents the pinnacle of drivetrain component engineering for high-performance RC monster trucks. Manufactured from strong steel using precision machining processes, this spur gear is built to withstand the extreme demands of 8S brushless systems that generate tremendous torque and power. The 47-tooth configuration combined with the 1.0 module gear pitch creates an optimal meshing interface with the pinion gear, ensuring smooth, efficient power delivery whilst minimising mechanical losses. The precision-engineered tooth profile eliminates the slack and inconsistency found in lower-quality plastic gears, resulting in responsive handling and predictable performance whether you're accelerating hard off the line, navigating technical courses or maintaining top speed on wide-open terrain. With steel construction providing superior wear resistance, this spur gear maintains its dimensional accuracy and tooth integrity over extended use, protecting your investment in your Kraton 8S or Outcast 8S brushless RC monster truck. The engineering specifically accounts for the characteristics of brushless motors, which operate at higher speeds and generate more torque than traditional brushed motors, making this gear an ideal replacement when your factory spur gear requires maintenance or upgrade.

Frequently Asked Questions
- Which ARRMA models is the Z-ARA310920 spur gear compatible with? — The ARRMA Spur Gear 47T Z-ARA310920 is designed for the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. Both models feature powerful brushless motors that this gear is engineered to support, making it an essential spare part for owners of these high-performance vehicles.
- Why would I need to replace my spur gear? — Over time, spur gears experience wear from constant meshing with the pinion gear, especially under the intense demands of 8S brushless systems. Regular maintenance and replacement of your spur gear ensures smooth power delivery, reduces noise and vibration, and protects other drivetrain components from damage caused by worn or damaged teeth.
- Is this a genuine ARRMA part? — Yes, the Z-ARA310920 is a genuine ARRMA manufacturer part, not an aftermarket copy or clone. Genuine ARRMA spares are manufactured to the same exacting standards as components supplied in factory kits, ensuring perfect compatibility and reliability with your Kraton 8S or Outcast 8S.
- What tools do I need to install this spur gear? — Installation requires basic RC car maintenance tools including a small screwdriver, hex keys and potentially a small press or spanner set depending on your model's specific design. Consult your ARRMA model's manual for detailed installation instructions, as the process varies between vehicle platforms.
- How often should I replace my spur gear? — Spur gear lifespan depends on driving intensity, surface conditions and maintenance practices. Weekend bashers might change their spur gear every 6-12 months, whilst competitive racers may do so more frequently. Regular inspection of your spur gear's teeth for wear, damage or tooth loss will indicate when replacement is necessary.
- What is the difference between 47T and other tooth counts? — The 47-tooth count represents the specific gearing ratio calibrated for the Kraton 8S and Outcast 8S platforms. Different tooth counts affect acceleration and top speed characteristics; ARRMA engineers selected 47T to deliver optimal performance for these monster truck models with their brushless powertrains.
