HUDY premium silicone oils are a go-to for RC racers and hobbyists who need predictable behaviour from their drivetrain. The HUDY 106581 bottle provides 80,000 cSt viscosity tailored for differential tuning in on-road and off-road cars, and production takes place in Europe with controlled lab checks for consistency.
Viscosity determines how a diff transfers torque between wheels. The thick 80,000 cSt grade offers higher internal resistance, helping to lock the diff slightly and boost traction and stability when cornering at speed or on loose surfaces.
HUDY uses a simple colour-coded system so you can spot the right viscosity at a glance. That makes swapping oils during tuning sessions straightforward, whether you are testing grip levels or matching damper oil to differential feel.
The HUDY 106581 comes in a 100ml bottle with a flip cap for controlled pouring and minimal mess. The volume is convenient for multiple refills and regular maintenance without needing frequent repurchases.
