RC Shock Tuning Oil 450cst 110ml - Arrowmax am-210039  [am-210039]

Precision damping oil for RC suspensions

This Arrowmax am-210039 silicone shock fluid comes in a 110ml bottle with a declared 450cst viscosity. It is suitable for use when filling and servicing shock absorbers on electric and nitro RC cars, enabling precise changes to damping behaviour by swapping oil weights.

Typical servicing steps include removing the shock, draining old oil, checking seals and shafts for wear, then refilling the specified volume while taking care to expel trapped air. Employ common shock rebuild tools and replacement parts; never force parts to fit if alignment is incorrect.

450cst will generally firm up damping relative to lighter oils and will affect both compression and rebound. You may need to adjust spring rates and preload and then run the car on representative terrain to assess the handling difference. Refer to shock and chassis guidance for recommended volumes and spring matchings.
