Ultimate Racing UR0790 is a 90wt high viscosity silicone oil designed to provide maximum control and stability in radio-controlled model shock absorbers. Thanks to its advanced formulation, it maintains a constant viscosity even at high temperatures, ensuring reliable and uniform performance during intensive use, both in hobby and competitive settings. The 90wt grade is suitable for rigid setups and demanding driving conditions, where minimizing suspension movement and obtaining a precise response is essential. Key Features: Viscosity: 90wt High performance silicone oil High thermal stability Improves precision and control Reduces roll, pitch and dive Product Code: UR0790 Applications: Off-road RC cars (buggy, truggy, monster truck) High performance on-road RC cars Advanced racing and tuning setup High grip tracks and compact surfaces Why choose 90wt? The 90wt oil is perfect for: very stiff and precise setups greater stability at high speeds drastically reduced suspension movement use on smooth or very grippy tracks Ultimate Racing represents a reliable choice for those who want to take their RC model to the highest level, with superior control and a professional response from the shock absorbers.
