Engineering focus on gear engagement and durability

The 3Racing 64 Pitch Spur Gear 88T Ver.2, reference 3RAC-SG6488/V2, is specified for racers and tuners who need repeatable drivetrain characteristics. Its 88 tooth, 64 pitch geometry supports closer tooth overlap and improved load distribution across the contact face.

Optimised mesh for competitive setups

This spur is intended to allow tighter mesh settings and reduced backlash, improving torque transfer efficiency at high RPM. Use it as part of a measured setup process that includes checking pinion alignment and bearing play.

Tuning considerations and fitment

When integrating this spur into a 1/10 on-road chassis, verify mounting pattern and clearances, and adjust slipper clutch or belt tension as needed to match the new gear ratio. Monitor wear patterns after initial runs to confirm correct alignment.

Start with a paper-thin feeler between pinion and spur, then tighten motor mount while rotating to seat teeth. Aim for minimal visible gap without binding and recheck after a controlled run.
Inspect for signs of rounding, pitting or uneven wear along the tooth face. If wear appears concentrated on one side, re-evaluate mesh alignment and bearing preload.
Belt and shaft systems require the same mesh clarity, but belt systems can be more sensitive to alignment along the centerline. Confirm parallelism and avoid lateral deflection when tightening components.
