The Tamiya 42207 VG Gear Differential Oil 800 is a precision silicone oil used to tune gear differentials in RC cars. It is aimed at enthusiasts who want tight, repeatable diff tuning for both on road and mixed surface setups.
This differential oil fits a wide range of Tamiya gear diff units, including TRF417 and TA06 style assemblies. By varying the oil weight in the diff you can influence slip characteristics for better traction and control.
Silicone oils such as the Tamiya 42207 maintain stable viscosity across temperature swings, which helps keep handling predictable during long runs or changing conditions, making setup changes more reliable.
