The 3RACING Cero Outer Shaft Hub 4mm (SAK-C144) is intended as a practical service part for Cero models. It helps preserve steering precision by providing a firm connection between wheel and axle, which keeps handling consistent during varied running sessions. The part fits cleanly into the factory layout to simplify repairs and maintenance.
Designed specifically for the Cero range, this 4mm hub gives a straightforward path to replace worn components without modifying the car. It is a good choice for both weekend club racers and casual hobbyists who want dependable wheel alignment.
Prepare basic RC tools and follow the standard removal of the old hub before fitting the SAK-C144. Confirm the hub seats squarely and that retaining hardware is tightened evenly to prevent binding.
