3Racing SAK-D4820 Aluminium Upper Arm Sakura D4 AWD Upgrade  [SAK-D4820]

Stiffen up your Sakura D4 AWD with aluminium upper arms

The 3Racing Sakura D4 AWD Aluminum Upper Arm, model SAK-D4820, is an effective upgrade for hobby drivers who want firmer suspension behaviour on the Sakura D4 AWD chassis. Built from durable aluminium, this arm reduces unwanted movement and helps keep suspension geometry more stable under load.

Why aluminium improves handling

Aluminium components offer greater rigidity than stock plastics while keeping weight reasonable. The 3Racing upper arm cuts down on part flex, which translates to sharper turn-in and more predictable mid-corner balance for both practice and club racing.

Compatibility notes and swap tips

Made for the Sakura D4 AWD platform, the SAK-D4820 uses the same mounting points as the original parts for a clean fit. Swapping in the arm is a simple job with common workshop tools and will not normally require chassis alterations.
