Frequently Asked Questions
- What does the 51-tooth centre differential spur gear do? — The centre differential spur gear controls the gear ratio in your Traxxas model's drivetrain, directly affecting how quickly your vehicle accelerates and what top speed it achieves. By changing from stock gearing to a 51-tooth configuration, you're adjusting these performance characteristics to suit your specific driving conditions and preferences.
- Which Traxxas models is the TRX8574 compatible with? — This centre differential spur gear is specifically compatible with the Traxxas UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck, available in both the Rigid Industries (TRX85086-4-RGD1) and Fox Racing (TRX85086-4-FOX1) variants.
- How do I know what tooth count I need? — The best approach is to consult your Traxxas model's owner manual, which will outline recommended gearing options for different running conditions. The 51-tooth option provides one of several available ratios, each suited to different balance points between acceleration and top speed.
- Is this suitable for beginners? — Whilst gear ratio tuning is more of an intermediate technique, the TRX8574 is straightforward to install for anyone with basic RC mechanical experience. Beginners should familiarise themselves with their vehicle's manual before attempting drivetrain modifications.
- How does changing the spur gear affect my RC car's performance? — A larger tooth count (like this 51-tooth option) generally provides stronger acceleration but lower top speed, whilst a smaller tooth count provides higher top speed but less acceleration. You'll want to match your gearing to your intended use—tight technical tracks, open circuits, or varied terrain all benefit from different setups.
- Is the TRX8574 a direct replacement for stock gearing? — Yes, this centre differential spur gear is a direct replacement component designed to fit your Traxxas differential housing perfectly. Simply follow your owner's manual instructions for safe removal of the old gear and installation of the new one.
