Hot Racing +4 mm Steel Drive Stub SCX30 HRASXTY39 AW04 increases your rig’s track width by 4mm per side to provide a more stable foundation for extreme climbing. By pushing the wheels further out, you effectively lower the functional center of gravity and reduce the risk of tipping on off-camber sections.
Precision-machined from high-strength steel, these stubs handle high-torque demands and heavy brass upgrades with ease. The extended design provides critical clearance for wider tires, preventing chassis rub during full suspension articulation. These components are essential for drivers looking to optimize their small-scale crawler for competitive performance and durability.
