This GPM aftermarket set provides front CVDs and rear axle shafts sized for small-scale TRX4M crawler models, made from medium carbon steel for durability in RC use. The set increases each axle side by 5mm using included brass spacers to widen the wheel track, which helps reduce roll and refines steering response on scale terrain.
The components are intended for installation at the front CVD and rear axle shafts area of the chassis, and they serve a tuning role—widening track width without changing wheel diameter or suspension geometry. Check clearances at the wheel arches and steering linkages after fitting to ensure no binding occurs.

For RC builders who want a modest track widen without altering wheel size, this medium carbon steel kit installs at the front CVD and rear axle shaft locations and provides +5mm per side track increase; verify fit with existing hubs and steering components before finalising installation.
