Product Description
AMSOIL Shock Therapy Suspension Fluid is formulated for maximum stability and high performance. AMSOIL Shock Therapy Suspension Fluids are formulated with shear stable synthetic base stocks with high viscosity indices. The complete additive package reduces foaming, aeration and wear, while seal conditioners are added to keep seals soft and pliable. AMSOIL Shock Therapy Suspension Fluids have been tested and proven to be superior, balanced products recommended for a wide range of temperatures and applications.

Controls Dampening and Rebound
AMSOIL Shock Therapy Suspension Fluids are formulated to make suspension systems more predictable. The base stocks of AMSOIL Shock Therapy Suspension Fluids have inherently high viscosity indices that effectively maintain their viscosities, while their antifoam agents reduce aeration and foam.

Reduces Friction and Wear
The constant friction within a shock body decreases suspension performance. AMSOIL Shock Therapy Suspension Fluid contains friction modifiers to reduce the energy loss caused by friction, while antiwear agents are added to protect shocks and forks from premature wear.
