This is not a beginner's component—it's engineered for RC hobbyists who have already discovered the joy of tuning and upgrading their vehicles, and who understand that investing in quality differential gears pays dividends in durability and performance. If you've been experiencing differential wear or simply want to future-proof your ARRMA 6S EXB against the stresses of aggressive driving, the Vitavon steel diff gears are the solution.
Key Features
- CNC-Machined Construction — Every tooth and surface of these differential gears is precisely machined using Computer Numerical Control technology, ensuring absolute consistency and perfect meshing between the pinion and ring gear, which eliminates play and delivers crisp, responsive power transfer to your wheels.
- 20CR Steel with Hardened Treatment — The gears are manufactured from premium 20CR steel and undergo a hardening process that increases their wear resistance and load-carrying capacity, meaning they can handle the extreme torque produced by brushless motors without stripping or cracking even under the most demanding driving conditions.
- Spiral-Cut Bevel Gear Design — Unlike traditional straight-cut gears, the spiral-cut profile distributes loads across a larger surface area and operates with reduced noise and vibration, resulting in smoother acceleration and a more refined driving experience across your RC car UK setup.
- 43/10T Gear Ratio — This specific tooth count combination is optimised for 6S brushless systems, providing the perfect blend of acceleration response and top-end speed that suits everything from tight technical tracks to open field bashing.
- 29mm Differential Case Compatibility — These gears are precision-engineered to fit exclusively within the 29mm differential case found on EXB variants; they will not fit 31mm diff cases, ensuring you order the exact right component for your model.
- Drop-In Replacement Design — Installation is straightforward—simply remove your worn stock gears (part numbers ARA310979 or RA310980) and install these Vitavon upgrades without requiring any case modification or additional machining.
- Universal EXB Compatibility — These gears work across the entire ARRMA 6S EXB range, including the Kraton 6S EXB V5, Kraton 6S EXB V6, Mojave 6S, Mojave EXB, and Notorious 6S EXB V6, making them a versatile upgrade for multi-vehicle collections.
Technical Performance
The Vitavon CNC HD Steel Diff Gear Pinion & Ring Gear set represents the pinnacle of differential upgrade engineering for ARRMA 6S brushless vehicles. Manufactured from 20CR steel with hardened treatment, these gears deliver exceptional durability compared to the softer aluminium or mild steel materials found in factory components. The CNC-machined construction ensures that each gear tooth is cut to exact specifications, eliminating the microscopic variations that can cause premature wear, noise, and slippage in stock differentials. The spiral-cut bevel gear design is a hallmark of premium RC components, offering superior load distribution that extends component lifespan even under extreme driving conditions.
The 43/10T ratio has been carefully selected for ARRMA 6S EXB platforms, which are equipped with powerful brushless motors capable of producing enormous amounts of torque through 3S or 6S LiPo batteries. This gear ratio strikes an ideal balance—it provides responsive acceleration without over-revving the motor, and maintains reasonable top-end speed for open-field bashers and competitive track driving alike. The hardened steel construction can withstand the brutal forces of rapid acceleration, aggressive cornering, and impact landings that are routine in RC car UK driving. Users of Vitavon components consistently report improved reliability and extended differential lifespan when compared to driving with stock gears, making this an investment that pays for itself through reduced replacement costs and more reliable performance during critical moments in races or events.

Frequently Asked Questions
- Will these Vitavon diff gears fit my ARRMA 6S model? — These gears are designed exclusively for ARRMA 6S EXB models with a 29mm differential case. They are compatible with the Kraton 6S EXB ARA8708V5, Kraton 6S EXB V6, Mojave 6S, Mojave EXB, Typhon, Notorious 6S EXB V6, and Fireteam models. Critically, they will not fit 31mm differential cases, so verify your differential case size before ordering. If you have an older Arrma 6S model or a different differential case size, you will need different gears.
- What is the advantage of steel gears over the factory aluminium components? — Steel gears, particularly those made from hardened 20CR steel like these Vitavon pieces, are significantly stronger and more durable than the softer materials used in stock components. Steel gears resist wear, stripping, and deformation far better, meaning they last substantially longer even under the extreme torque loads of brushless motors. This translates to fewer differential failures, more reliable performance, and ultimately better value for your money despite the higher upfront cost.
- Can I use these gears with a 3S LiPo battery or only with 6S? — The Vitavon CNC HD Steel Diff Gears are engineered for ARRMA 6S EXB platforms and will work perfectly with 6S LiPo batteries. They will also function with 3S batteries, though you'll lose some of the performance advantages and the gears will be over-engineered for lower power applications. For maximum benefit and to justify the upgrade cost, these gears are best paired with 6S LiPo power.
- How difficult is installation, and will I need special tools? — Installation requires removing your existing differential gears and installing the Vitavon components—a task well within the capability of intermediate RC car UK hobbyists. You will need basic hex drivers and possibly a small gear puller if your old gears are stuck, but no specialised or expensive tools are required. If you're unfamiliar with differential maintenance, your local RC hobby shop can install them for you, typically in under an hour.
- What is the difference between the 43/10T ratio and other gear ratios available? — The 43/10T ratio (4.3:1) is optimised for balanced performance across 6S brushless systems. Lower tooth counts on the pinion (such as 8T or 9T) create lower ratios that favour top speed but reduce acceleration and increase motor strain; higher pinion counts (11T or 12T) create higher ratios that favour acceleration but reduce top speed. The 10T pinion paired with the 43T ring gear represents the factory-recommended ratio for EXB variants and suits most driving styles.
- Are these gears suitable for beginners? — Whilst these gears are not technically difficult to install, they are best suited to intermediate or advanced RC enthusiasts who already understand differential maintenance and upgrading. Beginners should focus on learning to drive and maintain their stock vehicle before investing in premium upgrade components. That said, once you're ready to enhance your ARRMA 6S, these Vitavon gears are among the smartest first upgrades you can make.
- How long will these gears last compared to stock components? — The durability improvement depends heavily on driving style, maintenance, and the lubrication used in your differential. With proper care and quality diff fluid, Vitavon hardened steel gears typically last two to three times longer than stock components. Aggressive bashers may see slightly shorter lifespan, whilst users who maintain their differentials carefully can expect exceptional longevity—potentially many years of reliable service with minimal wear.
