Arrowmax am-210028 Silicone Diff Fluid 59ml 50,000cst for RC differentials  [am-210028]

Silicone Diff Fluid for RC Differentials

Arrowmax am-210028 is a 59ml bottle of silicone differential fluid formulated for radio-controlled model differentials where higher shear resistance is required. The 50,000 cSt viscosity offers a predictable, slow-flowing behaviour that helps reduce diff slip and stabilise drive transfer during acceleration and cornering on scale on-road and off-road setups.

In practical terms this fluid is used to adjust how quickly a diff allows wheel speed differences. Heavier fluids like 50,000 cSt increase coupling between axle outputs, which can reduce inside-wheel spin on corner exit and change handling balance. Use this product as part of a broader tuning approach alongside tyre choice, suspension settings and gear ratios.

Basic service workflow:

• Drain the old diff fluid and clean gears and bearings with appropriate RC-safe cleaner.
• Inspect O-rings and diff components for wear before reassembly.
• Add fluid to the diff housing to the desired level, rotate the gears to work the fluid through, and reassemble the unit.
• Allow a short break-in and test on track to evaluate handling changes, then fine-tune by moving to lighter or heavier diff fluids as needed.

Notes on handling and storage: keep the bottle capped and stored upright at room temperature, avoid contamination with dirt or other oils, and dispose of used fluid according to local regulations for automotive and hobby fluids.
