Race-Focused Steering Component

The 3Racing SAK-A550 is engineered for tuners running Sakura Advance 20M chassis where steering accuracy and repeatable setup are critical. Manufactured from 7075 aluminium, the arm reduces compliance at the front end to give clearer driver feedback through turn-in.

Material and Mechanical Benefits

7075 aluminium provides a high strength-to-weight ratio and improved fatigue life compared with softer alloys. The reduced deflection under load helps preserve toe settings and steering geometry during hard laps and chassis adjustments.

Installation and Setup Notes

Fitment is direct to Sakura Advance 20M mounting points. When installing, check servo alignment, steering centring and bump steer to optimise the new arm within your race setup. Consider hardened ball studs and correct torque to maintain consistent performance.

Expect reduced flex in the front end which can tighten turn-in. Revisit toe, steering throw and ackermann to fine tune handling balance for your track conditions.
Use hardened steel ball studs and quality turnbuckles to complement the SAK-A550. Upgrading servo saver components or a digital metal-gear servo will also capitalise on the arm's precision.
7075 offers higher yield strength and better fatigue resistance than common 6000 series alloys, making it preferable where stiffness and long-term dimensional stability matter.
