For racers and kit tuners, the HUDY 106630 Premium Silicone Oil 300,000 cSt delivers a heavy, stable viscosity for differential use. Manufactured in Europe to a controlled spec, it supports repeatable tuning outcomes.
The 300,000 cSt grade is part of HUDY's full viscosity range and is chosen when a strong locking effect is required. It is not intended for shock use, but for diffs where firm transfer and reduced slippage are needed.
Each viscosity is colour-coded for fast identification, and the 50ml bottle with flip cap makes dispensing straightforward while keeping your bench clean.
