Serious modelers looking for consistent differential behaviour can use the Arrowmax AM-210017 2,000cst silicone fluid to refine handling. The 59ml supply makes it easy to test different setups without wasting material.
This viscosity is effective when you need mid-level locking and responsiveness, particularly on surfaces that demand repeatable traction. It helps balance grip and steering feel for controlled driving lines.
Ensure the differential is fully stripped and cleaned before filling to avoid mixing contaminants with the new fluid. Fill carefully, cycle the diff to work the oil in, and check for correct operation after a short test run.
