Rhodex RC Silicone Shock Oil — 50 to 1000 cSt

Rhodex RC Line Silicone Shock Oil is a 100% pure silicone shock fluid for RC suspension, available in 20 viscosities from 50 to 1000 cSt in clean 50 cSt steps. Pick the exact weight your setup calls for — what’s on the label is what’s in the bottle, and it holds its rated viscosity under racing heat.

Key benefits

20 precise viscosities (50–1000 cSt) — the weight you need is on the shelf, no blending or rounding off
100% pure silicone — no PAO blends, mineral thinners or thickener additives; consistent batch to batch
Heat-stable — holds its rated viscosity through a run instead of thinning out like generic shock oils
Seal-safe — won’t swell or attack shock O-rings and seals
Race-day repeatability — tight cSt tolerance, so your setup notes carry over to the next bottle

Choosing a viscosity

Viscosity	Feel	Typical use
50–200 cSt	Thin, fast rebound, responsive	Light/small cars, smooth or indoor tracks, fine tuning
250–500 cSt	Mid-range, balanced	Most 1/10 buggies and touring cars, general racing
550–800 cSt	Heavier damping	Rough or bumpy tracks, bigger jumps, larger vehicles
850–1000 cSt	Maximum control	Heavy/large-scale, very rough terrain

Thinner (lower cSt) = faster rebound and more responsive; thicker (higher cSt) = slower rebound and more damping. Adjust weight up for control, down for response.
