VITAVON Arrma 6S HD Spider Gear/Diff Gear Set For 31mm Diff Case Only AR310436 - Vitavon Black VITAR310436

Overview

The VITAVON Arrma 6S HD Spider Gear/Diff Gear Set For 31mm Diff Case Only AR310436 represents a premium upgrade component for serious RC enthusiasts running ARRMA 6S platform vehicles in the UK and beyond. This is a specialist differential gear set engineered to replace the factory spider gears in your 31mm differential case, delivering enhanced durability and performance for bashers, racers and weekend warriors alike. Whether you're pushing your Arrma Mojave 6S, Kraton 6S, Notorious 6S or Typhon to the limits, this VITAVON upgrade is designed to withstand the punishment of high-torque 6S brushless power.

VITAVON has established itself as a trusted manufacturer of precision CNC-machined RC parts, and this spider gear set exemplifies their commitment to quality and longevity. Made from hardened steel using advanced CNC manufacturing processes, these gears are built to handle the extreme forces generated by 6S LiPo batteries and brushless motors. Unlike standard factory gears, VITAVON's hardened steel construction resists stripping, cracking and wear even during aggressive driving, making this upgrade essential if you want to extend your differential's lifespan and maintain smooth power delivery to the wheels.

This product is specifically engineered for the 31mm differential case found on certain ARRMA 6S models—it is absolutely critical to verify you have a 31mm diff case before purchasing, as this set will not fit 29mm cases. If you're looking for a durable, performance-enhancing upgrade for your RC car UK setup, this VITAVON spider gear set delivers professional-grade reliability at a competitive price point.

Key Features

• Hardened Steel Construction — These spider gears are manufactured from hardened steel, which dramatically increases their resistance to stripping, cracking and permanent deformation compared to factory plastic or softer metal gears, ensuring reliable power transfer even under extreme driving conditions.
• CNC Manufacturing — Each gear is precision-machined using CNC technology, guaranteeing exact tolerances and perfect tooth profiles that mesh smoothly with your existing differential components, reducing wear and maintaining consistent handling characteristics.
• 31mm Diff Case Compatibility — Specifically designed for ARRMA 6S models equipped with the 31mm differential case, this set ensures a perfect fit and optimal performance without modification or adapters required.
• Extended Durability — The hardened steel material and precision engineering mean these gears will outlast standard factory components by a significant margin, reducing the frequency of maintenance and repairs and ultimately saving you money over time.
• Smooth Power Delivery — The precise CNC tolerances ensure minimal backlash and smooth engagement, translating to responsive handling and consistent acceleration whether you're racing competitively or bashing on the weekend.
• Direct Factory Replacement — These spider gears are designed as a direct replacement for factory components, meaning installation is straightforward for anyone with basic RC maintenance knowledge and a few common tools.

Technical Performance

The VITAVON HD spider gear set represents a substantial upgrade in drivetrain durability for 6S brushless ARRMA vehicles. Manufactured from hardened steel through precision CNC machining, these gears are engineered to withstand the extreme torque and rotational forces generated by brushless motors running on 6S LiPo battery systems. The 31mm differential case is found on several ARRMA 6S platform models including the Mojave 6S, Kraton 6S, Notorious 6S, Typhon 6S and other variants, and these gears are calibrated specifically for this case size. The hardened steel construction provides significantly greater resistance to the common failure modes seen in standard factory gears—particularly tooth stripping, which occurs when softer materials cannot sustain the shear forces of high-power brushless systems. CNC manufacturing ensures that each gear's tooth profile is identical to every other, meaning backlash remains minimal and consistent across the entire differential. This translates directly to smoother acceleration, more predictable handling and less vibration transmitted through the chassis during aggressive driving. Whether you're running your ARRMA 6S vehicle on mixed terrain with a ready to run RC car setup or pushing it to competitive speeds on a track, these gears will provide the durability and reliability you need to keep your RC hobby enjoyable without constant rebuilds and replacements.

Frequently Asked Questions

• Will these spider gears fit my ARRMA 6S vehicle? — These gears are engineered exclusively for ARRMA 6S models equipped with a 31mm differential case. Compatible models include the Mojave 6S (ARA7604V2T1 / ARA7604V2T2), Kraton 6S (ARA8608V5T1 / ARA8608V5T2), Notorious 6S (ARA8611V5T1 / ARA8611V5T2), Typhon 6S (ARA8608V5), and Fireteam 6S (ARA7618T1 / ARA7618T2). It is absolutely essential to verify your vehicle has a 31mm diff case, as this set will not fit the smaller 29mm case found on some other 6S models. Always check your vehicle's specification sheet or contact the manufacturer if you're unsure.
• What is the stock part number for this product? — The official VITAVON stock part number is AR310436. Please double-check this against your vehicle's documentation before purchasing to ensure compatibility and avoid disappointment.
• Why should I upgrade from factory gears to VITAVON hardened steel gears? — Factory gears on ARRMA 6S vehicles are typically manufactured from softer materials designed for cost-effectiveness rather than ultimate durability. When you upgrade to brushless power and run high-performance 6S LiPo batteries, the torque output increases dramatically, and standard gears often cannot handle this without stripping or cracking. VITAVON's hardened steel construction and CNC precision engineering provide dramatically superior wear resistance, meaning your differential will remain reliable and require less frequent maintenance. Many UK RC enthusiasts find that upgrading to hardened steel gears is one of the most worthwhile drivetrain improvements they can make.
• How difficult is installation of this spider gear set? — Installation requires opening your differential case and replacing the existing spider gears with these new VITAVON components. This is a moderate-level maintenance task suitable for anyone with basic RC mechanical knowledge and appropriate tools. You will need a differential case tool or equivalent to safely access and reassemble your differential without damaging seals or tolerances. If you've never performed differential maintenance before, many local RC hobby shops in the UK offer installation services, or you can find detailed video tutorials online specific to your ARRMA 6S model.
• Will these gears improve my vehicle's performance? — These spider gears are not designed to increase speed or acceleration directly, but rather to provide superior durability and maintain consistent performance. By resisting wear and stripping, they ensure your differential continues to deliver smooth, predictable power transfer without degradation, which is particularly important if you're running your ARRMA 6S regularly on rough terrain or pushing high speeds. In practical terms, you'll experience fewer mechanical failures, more reliable handling characteristics and less need for rebuilds.
• How long will these gears last compared to factory components? — VITAVON hardened steel gears typically outlast standard factory gears by several times, depending on driving intensity and maintenance practices. Factors affecting longevity include the quality of differential lubricant used, driving style, terrain types and how frequently you service your vehicle. With proper maintenance, most users report that VITAVON hardened steel gears remain in excellent condition well beyond the point where factory gears would require replacement.
