Precision replacement for 3RACING Cero Outer Shaft Hub 4mm

The 3RACING Cero Outer Shaft Hub 4mm (SAK-C144) serves as a precise fitment item for Cero chassis tuning and race preparation. It maintains wheel-to-axle concentricity to support consistent suspension geometry and predictable steering response under load. Designed to integrate with factory component interfaces, it simplifies setup changes and reduces variables during tuning.

Racing oriented fit and function

Engineered for straightforward installation into Cero series layouts, this 4mm hub supports stable wheel location and repeatable alignment. Its profile minimises lateral play, aiding drivers who adjust toe and camber for tighter lap times.

Fitment notes for competitive use

Install using calibrated hand tools and verify axial seating to prevent binding that can affect steering precision. Inspect the hub and mating shaft for wear after high stress runs and replace as part of routine maintenance to keep setup consistent.
