Technical Performance
The FTX Rally MK2RS Diff Main Gear represents precision gear engineering designed specifically for 1/10th scale brushless rally car applications. Manufactured to OEM specifications by FTX, this 42-tooth differential gear is engineered using high-quality materials selected for their durability, wear resistance and smooth operational characteristics. The precise tooth profile and cutting ensures minimal backlash when meshing with the pinion gear, which is critical for maintaining responsiveness during the rapid throttle inputs and precise steering inputs required in competitive rally racing. The 42-tooth configuration has been carefully selected to provide an optimal balance between acceleration characteristics and top-end speed, allowing your FTX MK2RS to achieve quick getaways from corners whilst still maintaining effective cruising speed on straightaways. The gear's hardened finish protects against wear from the constant engagement and disengagement that occurs during normal driving, whilst the precision engineering ensures that power is transmitted smoothly and efficiently from the motor through to the wheels. For UK RC car enthusiasts running their FTX MK2RS in both casual bashings and competitive rally events, this gear delivers the reliability and performance consistency that genuine OEM components are known for.

Frequently Asked Questions
- Is this diff main gear compatible with all FTX Rally models? — No, this gear is specifically engineered for the FTX MK2RS 1/10th brushless rally car. The part number FTX11348 is designed exclusively for the FTX5470BK (black) and FTX5470W (white) variants of the MK2RS model. If you have a different FTX Rally generation or model, you will need to verify compatibility with your specific vehicle before purchasing.
- When should I replace my FTX Rally diff main gear? — You should consider replacing your differential main gear if you notice grinding noises coming from the gearbox area, if the gear has visible tooth damage or chipping, or if you experience a loss of power transmission efficiency during acceleration. Regular inspection after racing or bashing sessions can help identify wear before it becomes critical.
- What is the 42T specification and why does it matter? — The 42T specification refers to the number of teeth on the gear. This tooth count directly affects the gear ratio and therefore the performance characteristics of your FTX MK2RS. A 42-tooth main gear has been specifically selected by FTX engineers to provide the optimal balance of acceleration and top speed for rally car racing, ensuring your vehicle performs as intended across a variety of driving surfaces and conditions.
- Will upgrading or replacing this gear improve my FTX MK2RS performance? — Using a genuine OEM FTX gear ensures that your FTX MK2RS performs exactly as the manufacturer designed it. If your current gear is worn or damaged, replacing it with this new gear will restore your car to factory performance levels. For significant performance changes, you would need to explore different tooth count options, but this 42T is the factory-standard specification.
- Is this a genuine FTX part or an aftermarket replacement? — This is a genuine FTX original equipment manufacturer component, produced to the same exacting standards as the gear that comes with your new FTX MK2RS. You can be confident that you're getting an authentic, factory-specification part when you purchase from an authorised FTX retailer.
- Do I need any special tools to install this diff main gear? — Installation of the differential main gear requires removal of the differential housing and the pinion gear. You will need standard RC car tools including hex keys and screwdrivers. If you're unfamiliar with differential disassembly, we recommend consulting the FTX MK2RS instruction manual or seeking advice from experienced RC technicians.
