Is this suitable for competitive tuning setups?

Yes, the 3Racing 3RAC-SG4877/V2 is engineered to provide repeatable mesh characteristics, making it a good choice for tuned competitive cars where consistency matters.

Should I apply grease or oil to the spur?

Light, appropriate gear lubricant on the pinion and spur contact points can reduce friction and noise, but follow product and chassis recommendations to avoid attracting debris.

Does tooth count affect top speed?

Tooth count changes gear ratio, which can influence acceleration and top speed. Use the 77T spur with suitable pinions to find the balance you want for track or club racing.

How often should I inspect the gear?

Check the spur and pinion after heavy use or crashes and at regular intervals; early detection of wear keeps setups consistent.
