This GPM steel gear set replaces the internal gearbox gears used in AXIAL 1/30 SCX30 4x4 RTR brushed rock crawlers. Machined components use #45 steel with a black hardening treatment and are supplied as service parts for drivetrain maintenance or conservative tuning. These items are intended for RC-scale installation only.
Contained parts address the transfer and worm internals: Transfer Gear (mod 0.3), 30T Idler (mod 0.3), 40T Worm and a 12T gear. During installation verify gear mesh, endplay and bearing alignment to ensure correct tooth engagement; the set is supplied as replacement components rather than a complete gearbox assembly.
