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

7075-T6 alloy gearbox replacement

This aftermarket 7075-T6 CNC-machined aluminum transmission kit is designed for AXIAL SCX30 platforms and 1/30 scale brushed rock crawlers. It targets the gearbox shell and mounting surfaces to deliver a durable machined alloy alternative that helps maintain precise gear mesh alignment during demanding crawls.

Notes on fitment and mechanics: the assembly supports motor tooth-slot sliding adjustment so builders can set pinion engagement accurately and is presented as a replacement for original part AXI-3311. Internal gears and bearings are not supplied; installers must provide and fit these components and apply grease to ensure smooth operation.

The small fasteners come pre-packed in the box; final assembly takes routine hobby tools and attention to torque. For secure service life, treat metal-to-metal screws with medium-strength threadlocker where vibration might loosen connections.

When replacing the original case on an AXIAL SCX30, this GPM 7075-T6 alloy transmission kit offers a machined housing that promotes consistent pinion engagement and improved mesh stability; remember to fit separate internal gears and bearings and follow recommended greasing and threadlocking steps.
