AMSOIL Suspension Fluid Shock Therapy #5 Light (STL)

AMSOIL Suspension Fluid Shock Therapy #5 Light is a specialized suspension fluid formulated to deliver consistent damping performance and reliable protection in shock and fork systems. It’s designed to help maintain smooth, predictable suspension action across a wide range of riding conditions by resisting viscosity change, reducing foaming and aeration, and helping protect internal components from wear and corrosion.

Key Benefits

• Helps provide consistent damping and predictable suspension feel

• Resists viscosity change for more stable performance as temperatures change

• Helps reduce foaming/aeration to maintain smooth suspension action

• Helps protect internal components from wear

• Helps protect against rust and corrosion inside suspension components

Applications

Use in suspension systems where a #5 Light suspension fluid is recommended, including:

• motorcycle forks

• shock absorbers

• other suspension components requiring this viscosity grade

Service / Change Interval

• Follow the suspension or vehicle manufacturer’s recommended service interval (or your suspension tuner’s schedule), especially for severe riding conditions.

Note: Always confirm the correct suspension fluid weight/grade for your specific fork or shock before use.
