Key Features
- Factory Assembled and Pre-filled — This centre diff arrives completely assembled and filled with 100k cSt silicone oil, eliminating the need for manual assembly and oil filling, which means you get a perfectly balanced differential ready for immediate installation into your ARRMA buggy.
- 50T Steel Spur Gear — The inclusion of a 50-tooth steel spur gear provides increased durability under extreme loads, which is essential when you're pushing your RC buggy hard through rough terrain or competitive racing scenarios, ensuring the differential can handle the torque transfer without stripping or premature wear.
- Tough Steel Internal Gears — The internal gearset is constructed from hardened steel, delivering long-lasting durability in all conditions, whether you're running in wet weather, sandy environments, or dry tracks, meaning this centre diff won't let you down during extended bashing or race sessions.
- Strong Composite Diff Case — The housing is engineered from durable composite material that balances strength with lightweight construction, protecting the internal gears whilst maintaining the overall vehicle geometry and performance characteristics that ARRMA vehicles are renowned for.
- Metal Cross Shafts and Inserts — Precision-machined metal cross shafts and inserts replace plastic alternatives, delivering increased efficiency of fit and long-lasting durability that ensures smooth power delivery and eliminates play in the drivetrain over time.
- Included Bearings — The set includes all necessary bearings for fast and efficient fitting to your vehicle, meaning you won't need to source additional bearing sets or worry about compatibility issues when installing this replacement centre diff.
Technical Performance
The ARRMA Center Diff Set 50T 100k Oil represents precision engineering designed specifically for 1/8 scale RC buggies that demand reliable drivetrain components. The 100,000 cSt silicone oil fill is a critical specification—this viscosity provides the ideal balance between responsiveness and protection in a centre differential, allowing smooth power distribution between the front and rear axles whilst maintaining the necessary drag to prevent over-aggressive locking that could cause traction roll or instability. The steel internal gears combined with the metal cross shafts and inserts ensure that power transfer remains efficient and consistent throughout extended driving sessions, whether you're competing in organised RC racing events or enjoying casual weekend bashing. The 50-tooth steel spur gear is engineered to handle the extreme loads generated by modern brushless RC buggy motors and high-capacity battery systems, resisting the kind of wear and stripping that can occur with lighter aluminium alternatives or lower-quality steel. The composite diff case provides structural integrity whilst keeping unsprung weight to a minimum, which helps maintain suspension performance and vehicle handling characteristics. This centre diff set is compatible with both the ARRMA Typhon 6S V5 BLX (C-ARA8606V5) and the ARRMA 1/8 TLR Tuned TYPHON 6S 4WD BLX Buggy (C-ARA8406), making it a versatile spare part for UK RC enthusiasts running these popular platform vehicles.

Frequently Asked Questions
- What vehicles is the ARRMA Center Diff Set 50T 100k Oil compatible with? — This centre diff set is designed for the ARRMA Typhon 6S V5 BLX (C-ARA8606V5) and the ARRMA 1/8 TLR Tuned TYPHON 6S 4WD BLX Buggy RTR (C-ARA8406). If you own either of these models and are looking to service your centre differential or replace a damaged unit, this is the genuine OEM part you need.
- Do I need to assemble this centre diff myself? — No. This centre diff set arrives factory assembled and pre-filled with 100k cSt silicone oil, ready for installation. You simply need to fit it into your vehicle's differential housing—no additional assembly, oil filling, or calibration is required.
- What does the 100k cSt oil viscosity mean, and why is it important? — The 100,000 cSt (centistoke) rating indicates the oil's thickness at a standard temperature. This specific viscosity is chosen by ARRMA to provide optimal centre differential performance in their Typhon models, balancing lock-up characteristics with smooth power distribution. Using the correct viscosity is crucial for maintaining your vehicle's handling characteristics and drivetrain longevity.
- Is this suitable for both racing and casual bashing? — Yes, absolutely. The ARRMA Center Diff Set is engineered to handle both competitive racing applications and casual weekend bashing. The steel internal gears and 50-tooth spur gear are built to withstand the demands of either scenario, making this a versatile replacement or upgrade part for any Typhon 6S owner.
- What is the difference between the 50T and other spur gear options? — The 50-tooth spur gear in this set offers a specific ratio that ARRMA has engineered for optimal performance in their Typhon 6S models. If you are considering alternative gear ratios, you would need to consult ARRMA's technical documentation or speak with an RC specialist to understand how different tooth counts would affect your vehicle's acceleration, top speed, and overall handling.
- How often should I service my centre differential? — Centre differential servicing intervals depend on usage intensity and driving conditions. Regular racers might service every few months, whilst casual bashers can extend intervals further. However, if you notice any signs of drivetrain noise, loss of power distribution, or sluggish acceleration, it's time to service or replace your centre diff. Having a spare assembled unit like this one means minimal downtime.
