Maintain efficient power transfer and lower internal gearbox operating temperatures on your small-scale rock crawler with the GPM Aluminium Transmission Housing Set. Precision CNC-machined from high-strength 7075-T6 aircraft-grade aluminium, this three-piece upgrade case replaces factory composite housings to eliminate flexing under high-torque motor loads.

Designed with tight internal machining tolerances, this housing minimises gear slop to ensure smooth, quiet tooth engagement. The aluminium structure acts as a heat sink, drawing thermal energy away from transmission gears during long trail runs and steep climbs. Complete with 3D streamlined exterior contours and pre-installed hardware, this heavy-duty case restores driveline alignment and provides lasting protection on rough terrain.
