3Racing SAK-U314D Sakura Advance 20M Big Bore Damper Foam Insert  [SAK-U314D]

Refine Suspension Response on Sakura Advance 20M

The 3Racing Sakura Advance 20M Big Bore Damper Foam SAK-U314D is intended to refine damping behaviour in your kit. Designed around the SAK-U314/PK dampers, the foam insert increases energy absorption to smooth out bumps and steady the chassis during laps.

Improved Impact Control

Targeted at hobbyists who tune suspension settings, the Big Bore Damper Foam reduces harsh impact feedback and lowers midband vibration. The result is more predictable handling through corners and over undulating track surfaces.

Tailored Fit for Sakura Dampers

This insert matches the internal shape of the Sakura Advance 20M damper assembly to prevent unwanted slop. A snug fit helps keep damping forces consistent, aiding setup work and repeatable performance.
