Arrowmax am-210059 Professional 59ml 12,000cst Silicone Diff Oil for RC  [am-210059]

Product overview: silicone diff oil for tuning

Arrowmax am-210059 is a silicone differential oil supplied in a 59ml bottle with a nominal viscosity of 12,000cst, aimed at scale R/C model differentials. It functions as the damping medium inside gear or ball-type diffs where silicone oils are used to refine slip characteristics, traction transition and steering feel.

For setup and tuning, the oil's cst rating dictates how quickly the diff couples drive between wheels under load. Higher cst gives increased coupling and a slower slip rate, affecting corner exit traction and vehicle balance. This single-viscosity option gives a predictable mid-to-high damping characteristic for electric and nitro hobby cars.

Maintenance guidance: replace the fluid if you see inconsistent diff behaviour or during scheduled service, remove old fluid fully, refill to the level recommended by the diff manufacturer and reassemble using the chassis instructions. Allow time for the fluid to settle before final setup checks so changes are accurately reflected.

Storage and handling: keep the cap secure, store upright in a cool, dry area away from heat, avoid skin contact and ingestion, and dispose of used oil in line with local lubricant disposal rules.
