Frequently Asked Questions

What vehicles does this fit?: This gear fits many Traxxas vehicles using 1.0 Mod (1.0 metric pitch) gearing. Consult your vehicle's parts diagram or owner's manual to confirm fitment for your specific model before ordering.
What's the difference between spur gear tooth counts?: Fewer teeth on the spur gear increases top speed; more teeth increases torque and acceleration. The right choice depends on your running surface and driving style — your owner's manual will list the available range for your vehicle.
Is this a replacement or an upgrade?: Both. It serves as a direct stock replacement for vehicles that ship with a 38-tooth spur as stock, and it's also an optional tuning gear for vehicles where other tooth counts are stock but 38T is within the supported range.
Can I order online and pick up in Greeley?: Yes — shop online and ship to your door, or choose in-store pickup at JackWagon R/C & Hobbies in Greeley, CO.
