Track-Focused 86T Spur for Precise Gear Engagement

The 3RACING 48 Pitch Spur Gear 86T, model number 3RAC-SG4886, is aimed at competitive tuners who need repeatable mesh and minimal variation lap to lap. The 48 pitch tooth geometry keeps contact patterns stable under high RPMs.

Performance Notes for Tuners

This spur gear transmits motor torque into the drivetrain with reduced micro backlash when correctly meshed. Its 86-tooth count lets tuners refine acceleration versus top speed by selecting matching pinion steps without compromising engagement quality.

Compatibility Guidance for Race Builds

Designed for 1/10 scale race chassis that use 48 pitch systems, the 3RAC-SG4886 requires standard spline and centre distance checks. For best results, set mesh under load and verify contact pattern with a gear marking compound during final setup.

What mesh tolerance should racers aim for?

Aim for a minimal, consistent clearance across the tooth width. Slight toe in or out can be tested, but keep variation to a minimum to avoid tooth fatigue at race power levels.

Which pinion increments work best with an 86T spur?

Use standard 48 pitch pinion steps used by your class. Small tooth changes on the pinion fine tune acceleration and top speed while maintaining a stable mesh profile.

How do I inspect for gear wear in a race program?

Inspect for scalloping, chipped tips, and uneven wear across the face width. Replace if contact patterns shift or if fatigue signs appear after a race weekend.
