3Racing SAK-D403 Racing Front Upper Suspension Arm for Sakura D4  [SAK-D403]

Racing Grade Front Upper Arm for Sakura D4

The 3Racing Sakura D4 Front Composite Upper Suspension Arm SAK-D403 is developed to provide stable front geometry under load and support consistent steering feedback in tuned race setups. Its profile and mount points match the Sakura D4 layout to simplify trackside swaps.

Composite Design for Tuned Performance

The composite formulation is selected to limit unwanted deflection while keeping mass low, allowing finer setup adjustments to spring and damper rates without masking chassis response.

Consistent Handling for Competitive Running

With reduced compliance at the front upper locations, the SAK-D403 helps maintain predictable turn-in and mid corner balance, which is valuable when trimming steering and traction for qualifying runs.
