Yokomo YOKYS300 Silicone Super Blend Shock Oil #300 for RC Shocks  [YOKYS300]

Silicone Shock Fluid for Dampers

The Yokomo YOKYS300 Super Blend Shock Oil #300 is a silicone-based fluid formulated for RC-scale shock absorbers and suspension components. It is supplied as a tuning fluid to change damping behavior in model cars, and is sold only as a hobby part for scale vehicles.

Compatibility is broad rather than chassis-specific: use this oil in any RC shock cartridge or threaded shock body that accepts silicone shock fluids. Do not assume identical fitment between brands; consult your shock manual for recommended oil grades before making changes.

Service is straightforward for those familiar with shock maintenance: drain the old oil, inspect seals and pistons for wear, then refill and bleed the shock according to the design. Make small adjustments when testing; even modest shifts in oil weight or air volume can change damping noticeably. The product grade "#300" is provided as a selection guide relative to other weights.

In tuning terms, shock oil influences compression and rebound damping as part of the whole suspension setup together with springs, pistons, and preload. Use Yokomo YOKYS300 to refine body roll and weight transfer on a buggy or touring car, and confirm changes on a test run rather than relying on numbers alone. Keep the bottle sealed in a cool, dry place and avoid contaminating the fluid with dirt or solvents.
