AXIAL SCX30 Ford Bronco 7075-T6 Alloy Transmission Kit by GPM SCX30/38  [SCX30/38]

7075-T6 alloy transmission kit

This transmission kit is an aftermarket 7075-T6 CNC-machined aluminum replacement designed for AXIAL SCX30 platforms, intended for 1/30 scale brushed rock crawler setups. The kit focuses on the gearbox housing and mounting surfaces, offering a rigid machined alloy option where durability and alignment are important for low-speed crawling and precise gear mesh adjustments.

Key mechanical notes: the assembly allows motor tooth-slot sliding adjustment to fine-tune pinion engagement, and it is intended to replace factory part AXI-3311. Internal gears and bearings are not supplied, they must be installed by the builder, and the installer should apply appropriate grease to the gears during assembly to ensure smooth operation.

Packaging arrives with the small hardware pre-packed; final assembly requires standard hobby tools and a careful torque approach. For reliability, use a medium-strength threadlocker on metal-to-metal screws where vibration or loosening is a concern.

For builders upgrading an AXIAL SCX30 platform, this GPM 7075-T6 alloy transmission kit provides a precision-machined gearbox shell and mounting options that support tighter gear alignment and consistent pinion engagement; proper installation requires sourcing internal gears and bearings separately and applying grease and medium-strength threadlocker as noted.
