59ml Arrowmax am-210032 Silicone Differential Oil 200.000cst for RC Tuning  [am-210032]

Silicone oil for internal differential tuning

This Arrowmax am-210032 silicone diff fluid is made for RC-scale differentials to change internal damping characteristics. The compact 59ml bottle contains a high-viscosity oil suited to both gear and ball style diffs where tuners want to manage torque transfer between axles.

Using 200.000cst fluid increases coupling inside the differential, reducing relative gear movement and biasing rotation and traction. Tuners employ denser oils to steady mid-corner rotation, improve throttle predictability, and reduce slip on surfaces with limited grip.

Refilling a diff is straightforward: drain the previous fluid, inspect internal parts for wear, then introduce fresh silicone oil through the fill or pinion opening following the chassis manufacturer guidance. Work the diff through its range to eliminate trapped air and confirm even damping.

To evaluate handling changes, alter one axle at a time and keep a simple log of viscosities and effects. After use, cap the bottle and store upright to keep the oil clean and prevent evaporation.
