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.

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