Rhodex's bestselling silicone shock oil range. Twenty exact viscosities from 50 cSt ultra-light tuning oil to 1000 cSt heavy damping. Pure 100% silicone, heat-stable, seal-safe, and perfectly blendable for custom setups.
Generic shock oils suffer from viscosity variance — your 400 cSt today might behave like 380 cSt next month. That kills setup repeatability. Professional racers can't tune what they can't trust.
Rhodex Silicone Performance Fluid is engineered to exact cSt specifications, batch after batch. Pure silicone base — no PAO, no mineral oil dilution, no thickener compromises. The result: damping you can trust, race after race.
That's why thousands of racers chose Rhodex as their go-to shock oil. And it's why you'll find it at the top of Amazon's RC silicone oil bestseller list.
From 50 cSt cold-start rebound oil to 1000 cSt heavy damping for high-grip carpet — find your exact specification.
Cold-weather tuning, light rebound damping, and ultra-fast shock response. The lightest in the range.
Light damping for fast tracks and small-scale RC. Perfect blending base for custom setups.
Light-medium damping. Common viscosity for indoor carpet and high-grip surface tuning.
Light damping fluid. Popular for touring cars on smooth tracks and balanced suspension setups.
Mid-light damping. Versatile choice for off-road buggies and smaller RC platforms.
Standard medium-light damping. Excellent all-around viscosity for mid-grip surfaces.
Medium damping. The "sweet spot" viscosity used by countless racers as their default setup oil.
Medium damping. Reliable middle-range viscosity for off-road racing and bumpy tracks.
Medium-firm damping. Popular for short-course trucks and aggressive off-road driving styles.
Firm damping. Standard choice for 1/8 buggies and trucks on rough or jumpy tracks.
Firm damping. Higher control for technical tracks with sharp transitions and jumps.
Firm-heavy damping. For aggressive off-road and large-scale RC platforms requiring stiff control.
Heavy damping. For high-grip surfaces requiring tight body roll control.
Heavy damping for monster trucks, large-scale RC, and high-load applications.
Very heavy damping. Specialty viscosity for crawler shocks and ultra-controlled compression.
Very heavy damping. For extreme high-grip carpet and ultra-stiff rebound control.
Extra-heavy damping. Specialist viscosity for niche applications and extreme suspension setups.
Extra-heavy damping. For high-load racing, controlled compression, and stiff suspension behavior.
Ultra-heavy damping. Specialist viscosity for unique suspension setups and high-control applications.
Maximum damping. Top of the range for the heaviest setups and most demanding compression control needs.
Every Rhodex Silicone Performance Fluid shares the same precision-engineered base — only the viscosity differs.
No PAO dilution, no mineral oil contamination. Pure polydimethylsiloxane base for true viscosity behavior.
Resists viscosity fade under thermal stress. Your 400 cSt stays 400 cSt — from cold start to race finish.
Compatible with all standard shock seals, O-rings, and shock body materials. Won't swell or degrade rubber.
Mix any two viscosities for custom intermediate values. Predictable blending behavior every time.
Practical professional size. Squeezable bottle with precision dropper tip for clean, accurate dispensing.
Formulated and bottled in the United Kingdom. British manufacturing standards in every drop.
