Overview
The FTX Rally Diff Main Gear 50T (FTX11314) is an essential replacement or upgrade component for the FTX MK2RS 1/10th brushless rally car. Whether you're maintaining your current RC car UK setup or looking to fine-tune your vehicle's performance, this differential main gear is a critical drivetrain component that directly affects acceleration, top speed and overall handling characteristics. As a spare part designed specifically for the FTX MK2RS rally platform, this gear ensures you can keep your ready to run RC rally car performing at its best, whether you're bashing casually or pushing hard at the track.
The differential system in any RC car is fundamental to how the vehicle distributes power to the wheels, especially during cornering and acceleration. The main gear sits at the heart of this system, and choosing the right tooth count is crucial for optimising your vehicle's performance profile. The 50-tooth configuration offers a specific balance that appeals to drivers seeking particular handling characteristics and speed delivery. This genuine FTX spare part is manufactured to the same exacting standards as the original equipment, ensuring perfect fitment and reliability every time you need to replace a worn component.
RC Model Shop stocks this part as part of our comprehensive range of FTX spares and upgrades for the MK2RS platform. If you own this brushless rally car or are planning to build one, having spare drivetrain components on hand is simply good practice. Our UK-based stock means you can order with confidence, knowing you're getting an authentic FTX component with quick delivery and expert support from our experienced team.
Key Features
- 50-tooth specification — This gear ratio is engineered to provide a specific balance of acceleration and top-end speed, allowing drivers to tune their vehicle's performance characteristics to match their driving style and track conditions.
- OEM FTX component — Manufactured to the exact same standards and specifications as the original equipment fitted to new FTX MK2RS vehicles, guaranteeing perfect compatibility and reliability.
- Differential main gear function — This is the primary drive gear that sits within the differential case and distributes rotational force from the motor to the wheels through the planetary gears, making it critical to overall drivetrain performance.
- Direct replacement capability — If your existing gear has become worn, stripped or damaged through normal use, this part provides a straightforward replacement that restores your vehicle to factory condition and performance.
- Part of the FTX MK2RS ecosystem — Works seamlessly with other FTX Rally components including the diff case (FTX11313), planetary gears (FTX11349), and the complete drivetrain assembly.
- Available in alternative ratios — FTX offers this same component in 17-tooth and 42-tooth configurations, allowing experienced drivers to swap gearing to achieve different performance profiles without replacing the entire differential unit.
Technical Performance
The FTX Rally MK2RS is a 1/10th scale brushless rally car engineered for speed, agility and precision handling. The differential system is one of the most sophisticated parts of any RC vehicle, and the main gear plays the most important role within it. In the FTX MK2RS, the main gear works in conjunction with the motor, ESC and gearbox to transfer power smoothly and efficiently to both front and rear wheels. The 50-tooth main gear (compared to alternative 17-tooth and 42-tooth options) provides a mid-range gearing option that suits many driving styles and conditions. Understanding gear ratios is fundamental to RC tuning: a larger tooth count means more aggressive acceleration but lower top speed, whilst a smaller tooth count delivers faster top-end speed but requires more time to reach maximum velocity. The 50T configuration sits in the sweet spot for general purpose rally driving, offering responsive acceleration with respectable high-speed capability. The gear is manufactured from hardened steel to withstand the enormous forces present in the drivetrain, particularly during hard acceleration and during competition driving. When properly maintained and lubricated as part of the differential service, these gears provide many hours of reliable performance before requiring replacement due to normal wear.

Frequently Asked Questions
- What is a differential main gear and why do I need it? — The main gear is the largest gear inside the differential unit and is responsible for converting power from the motor into rotational motion at the wheels. It's the most heavily loaded component in the drivetrain. You'll need to replace it if it becomes worn, chipped or stripped through normal use, or if you want to change your vehicle's gearing ratio for different performance characteristics.
- Will this gear fit my FTX MK2RS? — Yes, the FTX Rally Diff Main Gear 50T (FTX11314) is specifically designed for the FTX MK2RS 1/10th brushless rally car and is a direct factory replacement. It will also fit any other FTX Rally models using the same differential platform.
- What's the difference between the 17T, 42T and 50T main gears? — These represent different tooth counts for the main gear, each offering different performance characteristics. The 17-tooth provides maximum top speed with slower acceleration, the 42-tooth offers a middle ground, and the 50-tooth (this product) delivers responsive acceleration with good top-end speed. Your choice should depend on your driving conditions and personal preference.
- How often should I replace my differential main gear? — Under normal recreational driving, a differential gear can last for many hours before requiring replacement. Heavy competition use or aggressive driving will necessitate more frequent replacement. If you notice grinding sounds from the differential or reduced power delivery, it's time to inspect and likely replace the gear.
- Do I need any special tools to install this gear? — You'll need to disassemble your differential case (FTX11313) to access the main gear. This is a technical procedure that requires careful handling to avoid damage to other differential components. If you're not experienced with RC maintenance, we'd recommend having this installation performed by an experienced RC technician or at a hobby shop.
- Is this a genuine FTX part? — Yes, this is an official FTX component manufactured to the same exacting standards as the original equipment. When you order from RC Model Shop, you're guaranteed an authentic FTX spare part, not a copy or aftermarket alternative.
