Team Corally Centre Diff Assembly 46T Main Gear Xpert Build C-00180-685

Overview

The Corally Centre Diff Assembly 46T Main Gear Xpert Build (C-00180-685) is a premium drivetrain component designed for serious RC car enthusiasts in the UK who demand performance and reliability from their machines. This centre differential assembly represents the pinnacle of Corally's engineering expertise, offering precision-machined components that will transform the handling characteristics of compatible RC buggies and bashers. Whether you're a competitive racer looking to fine-tune your RC car's performance or an experienced basher seeking durability and smooth power delivery, this centre diff assembly delivers exceptional value and quality.

Built using a combination of aluminium and steel materials, this Xpert Build differential is engineered to withstand the demands of both track racing and off-road bashing. The 46-tooth main gear configuration is specifically designed to work seamlessly with select Corally RC models, providing optimal gear ratios and power transmission efficiency. For RC enthusiasts in the UK looking to upgrade or repair their Corally RC car, this centre diff assembly offers genuine OEM quality with the precision you expect from one of the world's most respected RC manufacturers.

The assembly features 100K oil filling, which means the internal gearing is protected by a premium lubricant that reduces friction, extends component lifespan, and ensures consistent performance across a wide range of driving conditions. This is the kind of attention to detail that separates quality RC spare parts from inferior alternatives, and it's exactly why Corally parts are trusted by RC enthusiasts across the UK and beyond.

Key Features

• CNC-Machined 46T Main Spur Gear — The main gear is precision-machined using computer numerical control technology, which ensures absolute consistency in gear tooth profile and concentricity, resulting in smoother power delivery, reduced noise, and longer service life compared to conventionally manufactured gears.
• Aluminium and Steel Construction — The differential housing and internal components utilise a combination of lightweight aluminium and durable steel, providing the optimal balance between strength and weight for racing and bashing applications on any RC car UK terrain.
• Xpert Build Quality — This represents Corally's highest build standard for differential assemblies, meaning every component is inspected and assembled to exacting tolerances that ensure perfect mesh, minimal backlash, and maximum efficiency in power transmission.
• 100K Oil Filled — The differential internals are pre-filled with 100K viscosity oil, which provides superior lubrication of all moving parts, reduces friction and heat generation, protects gears from wear, and maintains consistent performance whether you're track racing or high-speed bashing.
• Wide Model Compatibility — This centre diff assembly is compatible with multiple Corally RC car models including the Spark6, Radix 6 (2021 and 2022 versions), Python (2020, 2021, and 2022 versions), Radix 4, and works as a tuning upgrade for the Kronos, Shogun, Dementor, and older Python 2020 models.

Technical Performance

The Corally Centre Diff Assembly 46T represents engineering excellence in RC drivetrain design. The 46-tooth main gear specification has been carefully selected to deliver optimal acceleration and top-speed characteristics across Corally's range of 1/10 and 1/8 scale RC buggies and bashers. The CNC-machining process ensures that each gear tooth is cut to precise tolerances, eliminating the micro-variations that can occur in conventionally stamped or hobbed gears. This precision translates directly to smoother mesh between the differential and pinion gear, reduced noise during operation, and improved efficiency in power transfer from the motor to the wheels. The combination of aluminium and steel materials provides excellent strength-to-weight characteristics; the aluminium components keep the overall assembly weight minimal, which helps preserve vehicle performance, whilst the steel components in the internal gear train provide exceptional durability under high-torque conditions. The 100K oil filling is critical to performance longevity — this viscosity grade is specifically chosen to provide adequate film strength under the extreme pressures generated within a differential while remaining thin enough to flow freely at both cold startup and under sustained high-speed operation. For RC car enthusiasts in the UK running brushless motors on 3S, 4S, or 6S LiPo batteries, this centre diff will handle the power delivery smoothly and reliably.

Frequently Asked Questions

• Which Corally RC cars is this centre diff assembly compatible with? — This C-00180-685 assembly is a direct spare part fit for the Corally Spark6 (C-00285), Radix 6 2022 (C-00185-R), Radix 6 2021 (C-00185), Python 2022 (C-00182-R), Python 2021 (C-00182), and Radix 4 (C-00186). Additionally, it works as a performance upgrade component for the Kronos 2020, Python 2020, Shogun 2020, and Dementor 2020 models, allowing you to improve their differential performance if needed.
• What does 100K oil filling mean and why is it important? — The 100K refers to the viscosity grade of the mineral oil pre-filled in the differential assembly. This oil lubricates all the internal gears and bearings, dramatically reducing friction and wear whilst helping to dissipate heat generated during operation. This oil-filled design ensures your centre diff operates smoothly and reliably for many hours of racing or bashing, and it requires minimal maintenance compared to dry differential systems.
• Is this Xpert Build quality worth the investment? — Absolutely. The Xpert Build designation means this differential has been assembled with premium tolerances and quality control standards. The CNC-machined gears ensure smoother, quieter operation, the precision assembly minimises backlash, and the quality materials mean your differential will withstand aggressive driving without premature wear or failure. For serious RC enthusiasts, a quality centre diff assembly is one of the best upgrades you can make.
• Can I upgrade my older Corally RC car with this centre diff? — Yes, this assembly is compatible with several Corally models from 2020 onwards, not just as a direct spare part replacement but also as a performance tuning upgrade for slightly older models like the Kronos, Shogun, Dementor, and Python 2020 variants. Always confirm your specific model number before ordering to ensure compatibility.
• What's the difference between this centre diff and cheaper alternatives? — The Corally Centre Diff Assembly offers several advantages: CNC-machining for gear precision, a combination of aluminium and steel for optimal strength-to-weight ratio, pre-filled 100K oil for consistent lubrication and protection, and Xpert Build assembly standards that ensure tight tolerances and reliability. Cheaper differentials often use stamped gears that generate noise, have loose tolerances that create backlash, and may use cheaper materials that wear faster under high-power brushless motor loads.
