Hardened Steel Helical Axle Gear Set 12T For 1/30 RC Crawler With CNC Machined Worm And Spur Gears, Smooth Meshing And Beefed Up Wear Resistance, Includes Two Identical Sets Compatible With SCX30

12T Hardened Steel Helical Gears for 1/30 RC Crawler Builds
✔️ Comes with two identical CNC machined sets for SCX30 axles

This gear set gives hobby builders a direct upgrade for the drivetrain in 1/30 scale RC crawlers. It slots into front and rear axles to handle daily trail runs or weekend competitions.

✅ Hardened steel build holds up under heavy torque loads
✅ Helical tooth profile cuts vibration during slow crawls
✅ Fixed 12T count keeps the ratio locked for torque setups
✅ Two full sets included so both axles match or you keep a spare

💡 Why do RC crawlers run helical gears instead of straight cut ones? Helical teeth roll into each other instead of clacking which keeps power smooth on technical lines. - Reduced noise and less stress on the motor during low speed sections - Better wear resistance so the gears last through seasons of rock work - Consistent mesh that stays tight even when the chassis flexes on uneven ground
