The 3Racing SAK-D6815A is a machined titanium steering travel stopper developed for the Sakura D6 platform to deliver consistent mechanical stop points. Its high modulus material reduces deflection under load and maintains steering geometry during high lateral forces, which helps preserve toe and Ackermann settings over time. Designed for racers who tune steering endpoints for predictable handling, the component fits common Sakura D6 mounts and integrates with aftermarket steering arms when clearance is confirmed.
