AXIAL SCX30 Transmission Gearbox Upgrade 7075-T6 for 1/30 Crawlers - SCX30/38 by GPM  [SCX30/38]

CNC-machined 7075-T6 gearbox housing

This aftermarket 7075-T6 CNC-machined aluminum gearbox housing is designed specifically for AXIAL SCX30 platforms and 1/30 scale brushed rock crawler applications. The component upgrades the original case and mounting faces to deliver improved rigidity and better-maintained gear alignment under load.

Key technical points: the housing allows motor tooth-slot sliding to accurately set pinion engagement and is supplied as a replacement for factory part AXI-3311. Internal gears and bearings are excluded from the kit and must be installed by the user; apply appropriate lubricants to the gears during assembly to preserve smooth function.

The package ships with the small fasteners included; final assembly needs standard hobby tools and careful torque control. To combat vibration-related loosening, treat metal-to-metal screws with a medium-strength threadlocker where needed.

For enthusiasts seeking a more durable transmission mount on AXIAL SCX30 machines, this GPM 7075-T6 alloy shell increases structural stiffness and helps hold consistent pinion engagement; remember to procure internal gears and bearings separately and follow good greasing and threadlocking practice.
