Shock oils

RC shock oil in a full range of weights for tuning your suspension.

RC shock oil is the silicone fluid inside your shock absorbers, and its weight controls how the car handles. We stock a full range of weights so you can dial in damping and rebound for your track and driving style. Thicker oil slows the shocks down, thinner speeds them up.Match the weight to your setup sheet and keep a few grades on hand for changing conditions. See all fluids in liquids, oils and glues.

Frequent Questions & Answers
What is shock oil?

Shock oil is the silicone fluid inside your shock absorbers. Its weight controls how fast the shock compresses and rebounds, which changes how the car handles.

How do I choose the right shock oil weight?

Follow your setup sheet as a starting point. Thicker oil slows the shocks for more grip on rough tracks, thinner oil frees them up on smooth surfaces.

How often should I change shock oil?

Refresh it when handling drifts off or the oil looks dark or thin. Racers often change it every few race days for consistent damping.

How do I fill shocks with oil?

Fill the body, move the shaft slowly to release air bubbles, let it settle, then bleed and cap. Doing both shocks on an axle the same way keeps them matched.
