This aftermarket set supplies front CVDs and rear axle shafts sized for small-scale TRX4M crawler models, manufactured from medium carbon steel for strength and practical longevity in RC use. The parts widen each axle side by 5mm using the supplied brass spacers to increase track width, which reduces body roll and improves steering precision on rough terrain.
The components are fitted at the front CVD and rear axle shaft locations of the chassis as a tuning upgrade to widen the track without changing wheel diameter or fundamental suspension geometry. Always check clearance at the wheel arches and steering linkages after installation to ensure there is no rubbing or binding.

For builders seeking a modest track widen without altering tyre diameter, this medium carbon steel kit installs at front CVD and rear axle shaft positions to add +5mm per side; verify fitment with existing hubs and steering parts before final assembly.
