AMSOIL Shock Therapy Suspension Fluids use high viscosity, synthetic, shear stable synthetic materials to reduce foaming, aeration and wear.  Seal conditioners have been added to maintain soft and pliable seals. AMSOIL Shock Therapy Suspension Fluids have been proven through testing and use for a wide range of temperatures and applications.

Controls Dampening and Rebound

AMSOIL Shock Therapy Suspension Fluid is formulated for fade-free damping and smooth rebounds.  This reduces rider fatigue, enables the driver to focus on the terrain ahead and ride longer and harder overall.

High Viscosity Index

AMSOIL Shock Therapy Suspension Fluid ensures a constant viscosity and allows for controlled flow through shock absorber orifices at a wide range of temperatures.

Reduce friction and Wear

AMSOIL Shock Therapy Suspension Fluid contains highly effective friction modifiers and anti-wear agents.  These are designed to reduce energy loss and heat build-up, protect against premature wear and maintain proper suspension and shock absorption.

Temperature and Performance

AMSOIL Shock Therapy Suspension Fluid, with a high viscosity index, high pour and high flash points, won't break down as it provides demonstrated performance at temperature extremes.  Its chemical composition makes it exceptionally resistant to volatility and decreases sludge and deposit buildups. 

Maintains Seal Pliability

AMSOIL Shock Therapy Suspension Fluid includes several seal conditioners designed to keep seals soft and pliable and prolong their service life.
