Yokomo YOKB7-S6AC Vented Shock Caps (4pcs)  [YOKB7-S6AC]

Shock cap aeration summary

This RC-scale aeration cap comes as a pack of 4pcs for general dampers and shock assemblies. The vented top is intended to manage airflow around the shock head and to be used as part of routine damper maintenance and setup.

Fitting is simple for anyone comfortable with normal damper servicing: support or drain oil as needed, remove the old cap, place the vented cap on the shock shaft or body in line with your damper layout, then reassemble. Standard shock service tools are sufficient.

On setup, the vented cap offers a defined outlet for trapped air and slight oil displacement during compression and rebound cycles, which can influence small changes in feel and rebound consistency. Use these caps together with spring selection, oil viscosity, shaft condition and piston choice for full tuning results.

Fitment advice: the part is described as a generic damper component; confirm dimensions and bench-fit before fitting to your car. Shock top sizes differ between manufacturers and chassis, so always check first.
