Yokomo YOKB7-S6AC Aeration Shock Cap 4pcs Set  [YOKB7-S6AC]

Vented shock cap overview

This RC-scale aeration shock cap is supplied as a set of 4pcs and is intended for use on dampers and shock assemblies across general RC applications. The cap is designed to vent and manage airflow at the shock top and is suitable for routine maintenance and damper tuning.

Installation is straightforward for anyone familiar with standard damper service: drain or support oil as required, remove the existing cap from the shock body, fit the vented cap onto the shock shaft or body according to your damper layout, and reassemble. No special tools beyond typical shock service tools are required.

In tuning, the vented cap provides a controlled path for trapped air and minor oil displacement during compression and rebound, which can produce subtle changes in feel and rebound consistency. Treat these caps as one element of a wider damper setup that includes spring choice, oil weight, shaft condition and piston selection.

Compatibility notes: this item is listed as a general damper part; verify physical fit with your shock body and shaft dimensions before installation. Because top dimensions vary between brands and chassis, confirm fit on the bench before track use.
