Arrowmax am-210023 Silicone Differential Oil 10,000cst 59ml  [am-210023]

Durable silicone oil for differential tuning

The Arrowmax am-210023 silicone diff fluid is provided in a 59ml bottle with a rated viscosity of 10,000cst and is intended for use in model differential housings to change traction bias and chassis balance without modifying mechanical geometry.

It is compatible with standard hobby differentials that accept silicone oil. The fluid is a tuning medium: increasing viscosity raises internal damping and limits differential action under load, while lighter oils allow freer wheel differential movement.

Routine installation is within the skill set of most model builders. Remove the diff following your chassis manual, open the case, drain the old fluid, apply the correct fill to the gearset and spider, then reassemble and test for smooth operation. Maintain cleanliness and avoid contaminating the oil with debris.

Practical note: this 10,000cst grade is suited to drivers seeking a firmer diff feel without changing gears or spiders. Expect interactions with tyre choice, suspension setup, and gear ratios; tune gradually and log changes for repeatable results.
