Technical Performance

The VITAVON 44T spur gear represents a significant advancement in drivetrain durability for ARRMA 6S electric RC vehicles. Built from 45# hardened steel—a material specification commonly used in industrial machinery and high-performance automotive applications—this gear provides substantially better wear resistance, fatigue strength, and dimensional stability compared to standard steel alternatives. The CNC precision machining process ensures that every tooth is cut to identical specifications, eliminating the micro-variances that can accumulate in injection-moulded or manually machined components. When this gear engages with your vehicle's pinion gear, the perfect tooth profile ensures smooth, efficient power transfer with minimal noise and vibration, allowing your brushless motor to deliver its maximum performance without energy loss to mechanical friction. The 44-tooth configuration has been specifically engineered for the 6S power class, optimising the balance between acceleration and top speed that drivers demand. At the heart of the ARRMA 6S design philosophy is the need for durable components that can handle the intense forces generated by brushless motors spinning at high RPM whilst driving through sand, mud, grass, and concrete. This spur gear was designed with those extreme conditions in mind. The Mod.1 rating ensures perfect compatibility with standard ARRMA pinion gears, maintaining the precise centre distance and meshing geometry that keeps your drivetrain running smoothly. For RC enthusiasts in the UK and beyond who demand the highest standards of build quality and performance, the VITAVON spur gear delivers genuine value by reducing downtime due to gear failures, improving driving consistency session to session, and providing the peace of mind that comes with knowing your drivetrain can handle whatever you throw at it.

Frequently Asked Questions

• Will this VITAVON spur gear fit my ARRMA Kraton 6S or Mojave 6S? — Yes, this gear is explicitly designed for ARRMA Kraton 6S and Mojave 6S models equipped with the 29mm differential case, which includes most standard production versions and the newer EXB variants (V5 and V6). The precise dimensions have been engineered to match ARRMA's specifications perfectly, ensuring flush installation without modification. If your vehicle uses a 31mm differential case (used in some other 6S ARRMA models like the Infraction or certain Typhon configurations), you will need a different gear size—specifically the VITAVON 50T model designed for 31mm cases.
• What is the advantage of 45# hardened steel over standard gears? — Hardened 45# steel offers superior resistance to stripping, wear, and deformation compared to standard steel or plastic alternatives. The hardening process increases the material's tensile strength and hardness, allowing it to withstand higher torque loads without permanent tooth deformation. For RC vehicles running 6S LiPo batteries with brushless motors, this increased durability translates to longer gear life, fewer failures during racing or aggressive bashing, and better overall reliability during extended driving sessions.
• Is this suitable as an upgrade from factory ARRMA gears? — Absolutely. Many RC enthusiasts in the UK and globally use VITAVON aftermarket gears as direct replacements for factory components, and report noticeably improved durability and performance. The CNC precision manufacturing typically exceeds factory quality standards, and the material hardness is superior. Whether you're upgrading preventatively to avoid future gear failures, or replacing worn factory gears after heavy use, this component will deliver a tangible improvement in drivetrain reliability and longevity.
• Will this gear work with my brushless motor and 6S LiPo setup? — Yes. This gear is purpose-designed for ARRMA 6S electric vehicles, which operate on 6S LiPo batteries (nominally 22.2V) and use brushless motors. The 44-tooth configuration and Mod.1 rating have been optimised for the power and RPM characteristics of typical 6S brushless drivetrain setups. Whether you're running a stock motor or a performance upgrade, this gear will handle the load effectively.
• What tools will I need to install this spur gear? — Installation requires basic RC mechanic's tools including an appropriate socket or spanner for the centre nut, and possibly a gear puller if removing the old gear proves difficult. Most RC enthusiasts doing their own maintenance will have these tools readily available. If you're not confident performing drivetrain work yourself, we recommend having installation carried out by an experienced RC technician to ensure proper torque specifications and alignment.
• How long will this gear last? — The actual lifespan depends on driving intensity, surface conditions, and maintenance practices. However, users consistently report that the VITAVON 45# hardened steel gear lasts significantly longer than standard alternatives—often 2-3 times as long under comparable driving conditions. Regular inspection and proper drivetrain lubrication will maximise gear longevity. Many competitive RC racers and serious bashers keep replacement gears on hand, not because they fail frequently, but because they drive intensively enough that having spares ensures they're never without a working vehicle.
• Is this a genuine VITAVON product? — Yes. RC Model Shop is an authorised retailer of genuine VITAVON components. All products sold through our store are authentic and backed by manufacturer specifications. You can be confident that the precision and quality you're paying for are genuinely delivered.
• What is the difference between this 44T gear and other tooth count options? — Different tooth counts alter the gear ratio between your motor's output and the wheels. A 44T spur gear with a standard pinion provides a specific final drive ratio optimised for 6S performance. VITAVON also offers other configurations such as the 50T model for 31mm differential cases (used in certain ARRMA 6S variants). The 44T is the correct spec for vehicles with 29mm diff cases. Changing tooth count significantly alters acceleration, top speed, and motor strain—always verify compatibility before installing gears with different tooth counts.
• Can I use this with older ARRMA 6S models or only the newer EXB versions? — This gear is compatible with both older and newer ARRMA 6S models, provided they are equipped with a 29mm differential case. Specifically listed compatibility includes: ARA8708V5 (Kraton 6S EXB), ARA8608V5 (Kraton 6S), ARA7604V2 (Mojave 6S), ARA7204 (Mojave EXB), ARA8611V5 (Notorious), ARA8606V5 (Typhon), ARA7618 (Fireteam), and others in this family.
