For model car tuners aiming for repeatable handling, the HUDY 106521 Premium Silicone Oil provides stable viscosity control. This 20,000cSt option is supplied in a 100ml European-made bottle to ensure uniform behaviour across multiple fills.
The HUDY portfolio covers oils from 100cSt through to 1,000,000cSt so you can match fluid thickness to shocks, diffs, or custom gearboxes. The 20,000cSt grade is well suited to diffs that need stronger coupling without being fully locked.
Colour-coded bottles let you find the right viscosity quickly, while the flip-top spout keeps application tidy. That lets you spend less time cleaning up and more time testing track settings.
