Gmade R1 Transmission Housing Aluminium Upgrade GM038 by GPM  [GM038]

Aluminium gearbox shell for R1 series

This aluminium transmission housing fits Gmade R1 platforms and Saw Back variants. As a metal replacement for the stock plastic unit, it aims to increase chassis stiffness and improve drivetrain alignment in 1/10 rock buggy setups.

The part is designed around compatibility and tuning rather than aesthetics: it mounts to the gearbox area used across the R1 family and provides a firmer anchor for drivetrain components. When fitting, check gearbox and wave mount alignment and reuse existing fasteners where appropriate to maintain correct spacing.

Choose this aluminium transmission housing when you want a more robust, scale-friendly unit for 1/10 R1-series rock buggies; confirm fit on your chassis and retorque screws after a short run-in.
