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

Aluminium transmission housing tailored to R1

This aftermarket aluminium transmission housing is made for Gmade R1 platforms and Saw Back models. Replacing the factory plastic housing with aluminium can improve chassis rigidity and help keep drivetrain components correctly aligned in 1/10 rock buggy configurations.

Its purpose is functional upgrade and fitment reliability rather than visual change: it mates with the gearbox area used across the R1 series and provides a firmer mounting foundation. During installation ensure correct alignment of gearbox and wave mounts and confirm screw and bearing positions to avoid binding.

Select this aluminium transmission housing for a more durable, scale-accurate gearbox shell on 1/10 R1-series rock buggies; always trial-fit components and recheck fastener torque after initial runs.
