Arrowmax am-210020 5,000cst Diff Oil 59ml  [am-210020]

Overview of silicone diff oils for RC

The Arrowmax am-210020 silicone diff fluid is formulated for use inside RC differential cases to refine traction and handling balance. Supplied as 59ml of 5,000cst oil, it provides a higher-viscosity option for tighter diff behaviour on electric models.

Use for diff rebuilds or when changing the internal damping to match surface grip and driver preference. Consistency in filling and bleeding procedures is crucial when evaluating different viscosities.

• Application: fill the diff case to the recommended level for your diff type, avoid air pockets for consistent behaviour.
• Tuning role: higher cst values increase internal resistance and can reduce inside-wheel spin under power, lower values allow freer differential action.
• Handling and storage: keep cap sealed and store upright away from extreme heat, and use a clean syringe or applicator to prevent contamination.

Consider this product a measured consumable; apply precise volumes and repeatable methods to obtain consistent handling results.
