The 3Racing SAK-D4820A Aluminum Upper Arm is a focused upgrade for the Sakura D4 RWD chassis, made to boost durability and handling precision. Its alloy construction helps the suspension keep consistent behaviour during repeated laps.
Using the 3Racing upper arm on a Sakura D4 RWD gives more consistent steering input and a stronger part that tolerates aggressive driving, making it a sensible upgrade for those refining lap times or improving durability.
