Technical Performance
The FTX Tracker Diff Main Gear (40T) is engineered as a critical component within the Tracker's differential assembly system. This 40-tooth main gear works in partnership with the complementary drive gear (16T model FTX10291) to establish the overall gear ratio and power delivery characteristics of your crawler. The differential housing and bevel gear set (sold separately) combine with this main gear to distribute torque intelligently between the wheels, a crucial feature for rock crawling and technical off-road driving where individual wheel traction control is essential. The precision-machined construction ensures smooth engagement and minimal backlash, contributing to reliable performance across a wide range of driving conditions. As part of the comprehensive FTX Tracker drivetrain system, this gear maintains compatibility with all standard FTX Tracker builds and configurations, making it an essential spare part for any serious Tracker owner.

Frequently Asked Questions
- Is the FTX Tracker Diff Main Gear (40T) compatible with all FTX Tracker models? — Yes, the FTX10290 is the genuine OEM part specified for FTX Tracker crawlers. However, always verify your specific Tracker version uses this exact 40-tooth configuration before ordering, as different variants may occasionally have alternative specifications. Our team at RC Model Shop can confirm compatibility if you're unsure.
- How difficult is it to replace this differential main gear? — Replacing this gear requires disassembling the differential housing and removing the existing gear. While not overly complex, the task does require some mechanical knowledge, basic RC car tools (Allen keys, screwdrivers), and patience. If you're new to RC maintenance, we recommend consulting the FTX Tracker assembly guide or visiting our Walsall store for guidance.
- What are the signs that my differential main gear needs replacement? — You may need to replace this gear if you experience slipping in the drivetrain, grinding noises during driving, reduced traction despite good tyre condition, or if the teeth become visibly damaged or worn. Regular inspection during maintenance sessions will help identify wear before it becomes a problem.
- Can I upgrade the gear ratio by using different tooth counts? — The 40-tooth main gear (FTX10290) paired with the 16-tooth drive gear (FTX10291) creates the standard ratio for the FTX Tracker. Changing either gear to a different tooth count would alter the overall drivetrain ratio, affecting acceleration, top speed, and torque characteristics. Always consult FTX documentation before attempting ratio modifications.
- How often should I inspect or maintain this gear? — For casual RC driving, inspect the differential monthly for wear and damage. For competitive use or heavy off-road driving, check after each use. Keep the differential properly lubricated with quality RC gear oil (sold separately) to extend component life and maintain smooth operation.
- What is the difference between this main gear and the bevel gear set? — The 40-tooth main differential gear (FTX10290) is the primary power input gear that receives torque from the motor and transmission. The bevel gear set (FTX10292) consists of smaller gears that work perpendicular to the main gear to distribute power to the left and right wheels, allowing differential action and independent wheel speed control.
