Overview
The ARRMA Diff Set Center 50T Z-AR220029 is an essential replacement spare part for RC car enthusiasts across the UK who demand reliable, high-performance drivetrain components. Whether you're a competitive racer, a weekend basher, or an RC hobbyist looking to maintain your ARRMA vehicle at peak performance, this front and rear centre differential set provides all the precision-engineered components needed to service your diff assembly and keep your RC car running smoothly. This genuine ARRMA spare part is designed to restore your differential to factory specifications, ensuring consistent handling and optimal power delivery to all four wheels.
Differential maintenance is crucial for any serious RC car UK enthusiast. Over time, differential gears wear down through intense use, track racing, or general bashing. A worn differential can lead to inconsistent handling, reduced traction, and poor acceleration. The ARRMA 50T Centre Diff Set addresses this by providing heavy-duty replacement gears and components manufactured to the highest standards. This complete set includes everything you need for a full differential overhaul, making it the ideal choice for anyone looking to refresh their ARRMA Mojave 6S, Typhon 6S, or compatible RC models.
Built with super-tough materials and precision manufacturing, this differential set is engineered to handle the demands of high-speed RC racing and extreme off-road bashing. The 50T spur gear provides excellent acceleration and torque delivery, whilst the sophisticated planetary and satellite gear arrangement ensures smooth, predictable power distribution. If you're running an ARRMA 1/8 scale brushless RC buggy or truck, maintaining your differential with quality OEM spares like this Z-AR220029 set is an investment in longevity and performance.
Key Features
- Super-tough Steel Crown Gear — The 43T straight diff crown gear is manufactured from premium hardened steel, providing exceptional durability and resistance to wear during high-speed acceleration and aggressive driving, ensuring your differential maintains optimal gear mesh and efficiency over extended periods of use.
- Precision Planetary and Satellite Gears — All planetary and satellite gears are machined from super-tough steel and engineered with precision-manufactured gear teeth that deliver consistent performance at high speeds, critical for maintaining predictable handling during competitive racing or fast-paced RC car track sessions.
- 50T Spur Gear — The included 50T spur gear provides the ideal balance of acceleration and top speed for most ARRMA models, delivering strong torque off the line whilst maintaining responsive throttle control for both circuit racing and off-road bashing applications.
- Super-strong Differential Case — Constructed from reinforced material with a specially designed case insert, the differential housing is engineered to withstand extreme loads and impact forces, protecting internal gears from damage during aggressive driving, jumps, and high-speed cornering.
- Metal Cross Shafts — Premium metal cross shafts replace plastic alternatives, offering increased efficiency of fit and exceptional durability that ensures smooth gear engagement and long-lasting performance without flex or wear.
- Precision Screw Threads — All fastening points feature precision-manufactured threads that allow fast and easy servicing, making differential maintenance straightforward for RC enthusiasts without specialist tools or technical expertise.
- Front and Rear Compatibility — This differential set is engineered as a complete front and rear assembly, ensuring uniform performance across both axles and delivering balanced, predictable handling characteristics across all driving conditions.
- Silicone O-rings and Gasket Seal — Included sealing components ensure a watertight fit, protecting internal gears from dust, mud, and moisture contamination during outdoor off-road RC car UK bashing sessions.
- Four Satellite Gear Shims — Precision shims allow fine-tuning of differential lock-up characteristics, enabling advanced users to customise the balance between traction and turning ability to suit specific track conditions or driving styles.
Technical Performance
The ARRMA Diff Set Center 50T Z-AR220029 represents the pinnacle of differential engineering for 1/8 scale brushless RC vehicles. Every component within this set has been manufactured to exacting tolerances, ensuring smooth operation and predictable performance whether you're driving your ARRMA Mojave 6S V2 BLX, Typhon 6S V5 BLX, or other compatible models. The 50T spur gear engages with the 43T straight crown gear through the planetary differential system, creating a sophisticated torque-sensing mechanism that automatically distributes power between the left and right wheels based on traction demands. This ensures that during acceleration, both wheels receive equal power, but as soon as one wheel loses traction, the differential allows the opposite wheel to maintain grip, critical for maintaining control during high-speed RC racing on UK circuit tracks.
The materials specification throughout this differential set reflects ARRMA's commitment to durability. Super-tough steel crown, planetary, and satellite gears resist the micro-fracturing and tooth stripping that can occur with inferior materials when exposed to the extreme stress of brushless motor power delivery. The metal cross shafts eliminate flex in the gear train, a common problem in plastic differential designs that causes inconsistent torque distribution and handling characteristics. The specially designed differential case insert strengthens the housing against the radial forces generated during aggressive cornering and jumping, whilst the precision-manufactured screw threads throughout ensure that components can be repeatedly disassembled and reassembled without stripping, essential for hobbyists who service their differentials regularly. The inclusion of silicone O-rings and a comprehensive gasket seal system means that your differential remains protected from moisture and contamination when driving off-road in wet UK conditions, extending the service life of internal components and reducing maintenance intervals.

Frequently Asked Questions
- Which ARRMA RC models is this differential set compatible with? — The Z-AR220029 is designed for use with ARRMA Mojave 6S V2 BLX (Red/Black and Green/Black variants), ARRMA Typhon 6S V5 BLX, and ARRMA 1/8 TLR Tuned Typhon 6S 4WD BLX Buggy. Ensure your model matches these part numbers before ordering: C-ARA7604V2T2, C-ARA7604V2T1, C-ARA8606V5, or C-ARA8406.
- Do I need special tools to install this differential set? — The precision-manufactured screw threads throughout this differential set are designed for fast and easy servicing with standard RC tool kits. Most owners can disassemble and reassemble their differentials using common hex wrenches and screwdrivers without specialist equipment.
- How often should I service my differential? — Differential service intervals depend on driving intensity and conditions. Weekend bashers might service annually, whilst competitive racers may maintain their differentials every few months. Regular servicing prevents wear-related performance loss and extends the life of your RC vehicle.
- What is the 50T gear ratio and how does it affect performance? — The 50T spur gear combined with the 43T crown gear creates a specific gear ratio that determines acceleration, top speed, and torque delivery. This combination is optimised for ARRMA 6S models, balancing strong acceleration with reasonable top-end speed, making it suitable for both track racing and off-road bashing.
- Can I adjust differential lock-up with this set? — Yes. The four satellite gear shims included in this set allow fine-tuning of differential lock characteristics. Adding or removing shims adjusts how much power is distributed between wheels, enabling customisation for different track conditions and driving styles.
- Is this suitable for beginners? — Whilst this is an OEM replacement spare part requiring basic mechanical knowledge to install, beginners new to RC car maintenance should consider having an experienced RC hobbyist or local RC Model Shop staff member assist with the first differential service. Once installed, the differential operates automatically with no user adjustment needed during driving.
- What makes this better than aftermarket alternatives? — As a genuine ARRMA OEM spare part, this differential set is engineered specifically for your vehicle's performance characteristics, geometry, and drivetrain specifications. OEM components ensure perfect fitment and predictable performance, whereas some aftermarket alternatives may require modification or produce inconsistent results.
