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

Silicone diff oil for RC differentials

This Arrowmax am-210020 silicone diff fluid is a scale RC accessory designed for use inside differential housings to dial in traction and roll behavior. The bottle contains 59ml of fluid labeled 5,000cst, a higher-viscosity option for tighter internal damping on electric RC models.

Use this fluid whenever diffs are rebuilt or when you need to alter internal damping to match track grip and driving style. Consistent filling and bleeding technique is as important as viscosity choice when comparing setups.

• 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.

This is a technical consumable for diff tuning; use proper tools and consistent methods to achieve repeatable on-track behaviour.
