Ultimate Racing UR0804 is a high viscosity 4000cSt silicone oil designed for use in radio-controlled model differentials where increased internal strength and superior traction control are required. Thanks to its advanced formulation, it maintains a constant viscosity even under stress and high temperatures, ensuring reliable and uniform performance during use. The 4000cSt grade is ideal for setups that require greater traction and stability, reducing slippage between the wheels and improving the model's response when accelerating and exiting corners. Key Features: Viscosity: 4000cSt High performance silicone oil High thermal stability Improves traction and power distribution Reduces slippage and loss of grip Product Code: UR0804 Applications: Off-road RC car differentials (buggy, truggy, monster truck) High performance on-road RC cars Advanced racing and tuning setup Use on medium-high grip tracks Why choose 4000? 4000 oil is perfect for: increasing traction on surfaces with good grip improving stability during acceleration reducing differential slippage obtaining more controlled and predictable behaviour Ultimate Racing is synonymous with quality and reliability in dynamic modelling, offering professional solutions to optimize every aspect of the performance of your RC model., PRECAUTIONS, non-toxic product, do not swallow, keep out of reach of children
