This steel gear set replaces the factory gearbox gears used in AXIAL 1/30 SCX30 4x4 RTR brushed rock crawlers. The kit uses #45 steel with a black hardening treatment and is supplied to serve as direct replacement parts for routine maintenance or modest drivetrain upgrades. The parts are intended for RC-scale installation only.
Included items cover the common internal gears found in the transfer/worm assembly: Transfer Gear (mod 0.3), 30T Idler (mod 0.3), 40T Worm and a 12T gear. Inspect gear mesh and bearing alignment when installing; the set is presented as replacement components rather than a complete gearbox.
