Competition oriented aluminium upper arm for precise setup work

The 3Racing Sakura D4 AWD Aluminum Upper Arm is intended for drivers focusing on setup consistency and predictable steering behaviour. The aluminium construction reduces component deflection, aiding repeatable tuning and control during aggressive drift lines.

Stable links for refined steering geometry

With reduced compliance compared to plastic, the SAK-D4820/BK helps maintain steering and toe settings under load, delivering a touchpoint for tighter setup adjustments. This stability assists when dialing in camber, toe and steering rack settings.

Fitment and practical installation notes

Engineered for direct compatibility with Sakura D4 AWD mounting points, the arm allows straightforward replacement without altering baseline geometry. Confirm ball stud placement and torque values during installation to retain consistent performance.

How does aluminium affect setup sensitivity?

Aluminium reduces flex, which increases sensitivity to small alignment changes. Expect finer feedback when adjusting toe and steering rack settings.

Should I change my steering linkage after fitting?

Not necessarily. However, check linkage geometry for any free play and verify that ball joints sit correctly to avoid binding at full lock.

What should I check during setup sessions?

Monitor toe stability, steering centring and how the car reacts during sustained slides. Small increments to setup are recommended once the aluminium arm is fitted.
