Performance Aluminium Upper Arm for Competitive Drifting

The 3Racing Sakura D4 RWD Aluminium Upper Arm, SAK-D4820A/BK, is engineered to deliver repeatable suspension geometry under hard drifting conditions. The precision machined aluminium body reduces compliance that can alter steering and camber under load.

Precision and Setup Benefits

Built with racing setup work in mind, this arm helps maintain intended roll centres and camber settings, enabling finer adjustments to toe and steering ackermann. It supports consistent lap to lap behaviour for drivers chasing predictable handling.

Fitment and Practical Notes for Tuners

Designed to bolt into Sakura D4 RWD mounting points, the arm facilitates quick comparisons between stock and upgraded geometry. When tuning, verify ball stud heights and use matched fasteners to preserve alignment precision.

The stiffer aluminium arm reduces lateral deflection, which helps keep roll centre position more stable under load, aiding predictable weight transfer during drifts.
After fitting, confirm ball stud heights, torque all fasteners to spec, and run progressive tests to observe changes in steering response before finalising settings.
Yes, but ensure clearance and geometry remain correct. Low profile setups may require matched knuckles and correct ball stud selection to preserve intended angles.
