AMSOIL Shock Therapy® #5 Light Suspension Fluid Description

AMSOIL Shock Therapy® #5 Light Suspension Fluid resists viscosity loss over a broad temperature range for consistent, effective suspension feel. It reduces foaming, aeration and wear, while conditioning seals for maximum life.

AMSOIL Shock Therapy #5 Medium Suspension Fluid

Formulated for Fade-Free Dampening and Smooth Rebounds in High Performance Applications

A properly functioning suspension is vital to performance during a race or maneuvering around obstacles on the trail. For greatest effectiveness, riders need consistent suspension feel over a broad temperature range. Aggressive riding, however, can heat suspension fluid enough to cause viscosity loss, resulting in soft, inconsistent feel. AMSOIL Shock Therapy Suspension Fluid resists viscosity loss over a broad temperature range for consistent, effective suspension feel. It reduces foaming, aeration and wear, while conditioning seals for maximum life.

AMSOIL Shock Therapy #5 Light Suspension Fluid
  • High viscosity index helps prevent fade under extreme temperatures
  • Consistent, smooth dampening
  • Seal conditioners for extended service life
  • Race-grade technology

Controlled Dampening and Rebound

AMSOIL Shock Therapy Suspension Fluid is formulated to make suspension systems more predictable. Its base oils have inherently high viscosity indices that effectively maintain viscosity, while its anti-foam 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 anti-wear agents protect shocks and forks from premature wear.

Recommendations

Use AMSOIL Shock Therapy Suspension Fluid in front forks and shocks on snowmobiles, dirt bikes, motorcycles, ATVs and other racing and recreational-use vehicles, as well as cars and trucks that require suspension systems that perform in the most extreme conditions. Agitate the fluid before use. Shock Therapy Suspension Fluid Light #5 is the preferred choice for winter use.

Use AMSOIL Shock Therapy Suspension Fluid Light #5 in suspension systems and forks where less dampening and quicker rebounds are desired, including those made by Showa, Kayaba, Bilstein, RydeFX, Penske, WP, RACETECH, (US1) and Custom Axis.

Use AMSOIL Shock Therapy Suspension Fluid Medium #10 in suspension systems where more dampening control and slower rebounds are desired, including those made by Öhlin, FOX, RACETECH (US2), Koni and WP shocks, and Harley-Davidson forks that recommend type "E" or "B" fork oil.

Great oil

I've run this in a few dirt bikes and recently put it in the suspension of my YZ250. Creates really smooth action for the suspension. Good stuff.
