This aftermarket 7075-T6 CNC-machined aluminum transmission kit is produced for AXIAL SCX30 platforms, intended for 1/30 scale brushed rock crawler applications. It focuses on replacing the gearbox housing and mounting surfaces to provide a stiffer alloy option that helps keep gear mesh consistent during low-speed crawling.
Technical summary: the assembly supports motor tooth-slot sliding to fine-tune pinion engagement and is supplied as a replacement for factory part AXI-3311. Internal gears and bearings are not included and must be provided and installed by the builder; use suitable grease on gear teeth during assembly for reliable operation.
Small hardware comes pre-packed in the carton; final assembly requires standard hobby tools and sensible torque control. For secure service, apply a medium-strength threadlocker to metal-to-metal screws where vibration is expected.

For AXIAL SCX30 owners seeking a machined 7075-T6 gearbox shell, this GPM transmission kit enhances case rigidity and supports repeatable pinion engagement; internal gears and bearings must be sourced separately and proper greasing and threadlocker use is recommended during installation.
