Arrowmax am-210059 12,000cst 59ml Diff Fluid for R/C Differentials  [am-210059]

Technical notes on differential damping

Arrowmax am-210059 is a silicone differential fluid supplied in a 59ml bottle at a nominal viscosity of 12,000cst, for use in scale R/C model differentials. The fluid provides damping inside gear or ball-type diffs where silicone oils are chosen to control slip, traction transition and steering characteristics.

From a tuning perspective, the viscosity figure controls the rate at which the diff transfers torque between wheels under load. Increasing cst raises coupling and slows slip, which in turn affects corner exit grip and overall chassis balance. This single-viscosity product offers predictable mid-to-high damping for both electric and nitro models.

Recommended service steps: replace the fluid if diff performance becomes inconsistent or during scheduled maintenance, fully remove the old fluid, refill to the level advised by the differential or chassis maker and reassemble following the manual. Allow the fluid to distribute inside the unit before completing setup checks.

Storage and handling guidance: keep the bottle closed, store upright in a cool dry area away from heat, avoid skin contact and ingestion, and dispose of used fluid in accordance with local waste rules for lubricants.
