Technical Performance

The Traxxas Spur 72-tooth Gear delivers precision engineering that keeps your RC car running smoothly mile after mile. Spur gears are considered consumable items in RC vehicles and require periodic replacement to ensure maximum performance from your model, much like tyres or brake pads in full-size vehicles. This gear is manufactured to exacting standards with attention to tooth profile geometry, ensuring even distribution of load across all teeth during engagement. The 0.8 metric pitch specification provides compatibility with a range of Traxxas electric RC platforms, whilst the 32-pitch designation offers additional flexibility for builders working across different model generations. Constructed from hardened materials, the spur gear is engineered to withstand the constant rotational stresses of high-performance RC driving. Regular visual inspection after each run—checking for wear patterns, chipping, or small debris lodged between teeth—will help you identify when replacement is needed. Signs of excessive wear include visible tooth damage, flat spots on the tooth profile, or difficulty maintaining consistent mesh with your pinion gear. For electric vehicles, the actual replacement process is quite simple and requires no special tools beyond a hobby knife for debris removal and a screwdriver for the three 3mm fasteners that hold the gear in place.

Frequently Asked Questions

• How often do I need to replace my RC spur gear? — Spur gears are classified as consumable items and the frequency of replacement depends on how much you run your RC car and the conditions you drive in. After every run, visually inspect your spur gear for signs of wear or small debris lodged between the teeth. Small stones can be carefully removed with a hobby knife, but if the gear shows signs of excessive wear, replace it before continuing to run your model to prevent damage to other drivetrain components.
• Is this gear compatible with my Traxxas RC car? — The Traxxas Spur 72-tooth Gear with 0.8 metric pitch and 32-pitch compatibility is designed for Traxxas electric RC vehicles. However, compatibility varies by specific model, so we recommend checking your vehicle's manual or contacting our RC experts to confirm this part fits your particular model before ordering.
• What tools do I need to replace my spur gear? — Replacement is quite straightforward for most Traxxas electric vehicles. You'll need a screwdriver to remove the three 3mm CS screws that hold the spur gear onto the slipper hub, and a hobby knife to remove any small debris. For torque control type assemblies, you won't need to remove the slipper clutch nut, making the job even simpler.
• How can I tell if my spur gear needs replacing? — Visually inspect your spur gear after every run. Look for signs of excessive wear such as tooth damage, flat spots on the tooth profile, or visible chipping. If you notice the mesh between the spur gear and pinion gear becomes inconsistent, or if you see small stones or debris embedded in the teeth, it's time for replacement to maintain peak performance.
• Will this help improve my RC car's performance? — A fresh spur gear in good condition ensures smooth, efficient power transfer from your motor to the wheels. If your existing gear is worn, replacing it with this genuine Traxxas part will restore smooth meshing with your pinion, reducing drivetrain noise and vibration whilst improving overall drivetrain efficiency and reliability.
