The 3Racing SAK-A546C damper bottom cap is engineered to tighten tolerances at the lower shock interface on the Sakura Advance 20M. Its design supports more consistent damping performance under race conditions and helps retain alignment during repeated service cycles.
Specifically matched to Sakura Advance 20M shock geometry, the SAK-A546C improves consistency when swapping oils or springs and reduces unwanted movement at the damper base. That stability makes setup changes more predictable and simplifies corner by corner tuning for lap time improvements.
