Competition oriented 48P 77T spur from 3Racing

The 3Racing 48 Pitch Spur Gear 77T Ver.2 is produced to deliver consistent tooth engagement and repeatable mesh characteristics for tuned race cars. Its 48-pitch 77-tooth geometry supports predictable drivetrain response, making it suitable for drivers who frequently adjust pinion sizes and gear mesh to refine handling.

Technical Notes on the 3Racing Spur

  • Brand: 3Racing
  • Pitch: 48
  • Tooth Count: 77T
  • Application: Intended for competitive and club racing rigs that specify 48-pitch spur gearing

What should I check when setting gear mesh for racing?

Set a consistent minimal clearance at the tooth root, verify mesh under load and after a few runs, and retighten mounting hardware. Consistency lap after lap is key for race tuning.

Are there any setup considerations for durability?

Avoid excessive torque spikes, check motor timing and gearing combinations, and inspect teeth after impacts. Preventing overloads preserves gear life during events.

How does this spur help with tuning changes?

The stable 48-pitch tooth form gives predictable changes when you alter pinion size or backlash, so tuning adjustments produce reliable results without unexpected mesh shifts.
