Overview
The FONZON 50T Full Metal Split Centre Differential is the ultimate drivetrain upgrade for your ARRMA 6S RC car, engineered to deliver exceptional performance and bulletproof durability on demanding terrain. Whether you're bashing at the weekend or competing seriously, this precision-machined differential represents pro-grade engineering that transforms how your ready to run RC vehicle handles power delivery and traction. Designed specifically for the ARRMA 6S platform, this centre diff is the top factory replacement choice and is suitable for virtually all ARRMA 6S models currently available in the UK market, from the iconic Kraton 6S to the high-performance Typhon 6S.
Built from premium materials and pre-assembled at the factory, the FONZON 50T arrives ready to run straight out of the box with zero fiddling required. The 50T tooth configuration strikes an excellent balance between wheel speed and torque, making it ideal for everyday off-road running as well as more demanding competitive driving styles. Unlike budget differentials that wear quickly under load, this full metal centre diff is machined to exacting tolerances and filled with quality 100K cSt differential oil, ensuring smooth power distribution even when you're pushing your RC model truck or buggy to its limits across rough, rocky terrain.
RC enthusiasts across the UK trust the FONZON brand for drivetrain reliability. This centre differential delivers the kind of rock-solid stability you need whether you're racing against friends, tackling challenging trails, or just having fun bashing through the countryside. The optional LSD (Limited Slip Differential) clutch plate set included in the box allows you to fine-tune traction control and performance characteristics, letting you dial in the perfect feel for your driving style and track conditions.
Key Features
- Fully CNC-Machined Nickel-Chromium Alloy Steel Gears — These gears are manufactured from premium 4340 steel that delivers superior strength and exceptional wear resistance, ensuring the differential maintains precision and reliability even under the extreme loads and stress of competitive RC driving or intense bashing sessions.
- 7075-T6 Aluminium Centre Housing — Engineered from aviation-grade 7075-T6 aluminium, the centre housing provides lightweight rigidity without compromising durability, whilst the finely polished finish gives a professional appearance that matches high-end RC builds.
- Extended Nickel-Chromium Steel Drive Cups with +1.5mm Extension — These optimised drive cups are specifically designed to reduce drivetrain angle stress, which is critical for maintaining smooth operation and preventing premature wear on your RC car's transmission components during aggressive driving.
- Grade 12.9 Titanium-Coated Screws — Featuring a corrosion-resistant gold finish, these precision-grade fasteners ensure long-term reliability and resist degradation from moisture, dirt, and the elements encountered during outdoor RC operations.
- Sealed High-Performance Adapter Cup Bearings — These premium bearings deliver smooth, efficient rotation with minimal friction, contributing to both performance and longevity of your RC drivetrain.
- Pre-Filled with 100K cSt Differential Oil — The differential arrives factory-filled with quality differential oil at the optimal viscosity for immediate use, eliminating the need for messy filling procedures and ensuring correct lubrication from day one.
- Includes Optional LSD Clutch Plate Set — The included Limited Slip Differential clutch plates allow you to enhance traction control and adjust the differential's behaviour, enabling you to tune performance characteristics for different terrain types and driving conditions from casual bashing to serious racing.
Technical Performance
The FONZON 50T Full Metal Split Centre Differential represents modern engineering excellence in RC drivetrain design. Every component has been precision-engineered and CNC-machined to tolerances that match factory original specifications, ensuring your ARRMA 6S platform vehicle operates with professional-grade stability and reliability. The fully metal construction throughout eliminates the plastic components found in budget differentials, dramatically improving durability under high loads whilst maintaining smooth, predictable power distribution across extreme terrain. The 50T tooth count delivers an intelligent balance between wheel speed and torque delivery, making this differential equally at home during high-speed bashing runs or technical competitive racing where precise traction control matters. The sealed high-performance adapter cup bearings minimise friction losses and ensure consistent performance throughout extended driving sessions. Built from premium 4340 nickel-chromium alloy steel gears and housed in rigid 7075-T6 aluminium, this centre diff is engineered to withstand the punishment of 6S LiPo power systems whilst maintaining precision engagement. The extended drive cups reduce drivetrain angle stress, a critical factor for longevity when running powerful brushless RC cars on rough terrain. The Grade 12.9 titanium-coated fasteners resist corrosion from mud, water, and salt, making this differential suitable for genuine all-weather RC use across the UK.
