RC Differential Tuning Fluid 200.000cst 59ml - Arrowmax am-210032  [am-210032]

200.000cst silicone fluid for RC diffs

This Arrowmax am-210032 silicone diff fluid is supplied for RC models where changes to internal damping affect handling. The 59ml container provides a high-viscosity option for both gear and ball differentials to modify torque transfer behavior.

At 200.000cst the oil increases the coupling effect inside the diff, slowing side gear movement and altering rotation bias and traction. Tuners select heavier fluids to stabilise mid-corner rotation and to control inside-wheel spin under acceleration on low-grip tracks.

Refilling is a standard maintenance and tuning operation: remove or access the diff, drain the old oil, inspect components, then add the new silicone through the fill or pinion opening following the chassis maker's procedure. Operate the diff to eliminate trapped air and confirm consistent damping.

Because viscosity changes handling, adjust one axle at a time during testing and keep concise notes of which viscosities were tried and their effects. Reseal the bottle after use and store upright to maintain fluid integrity.
