AMSOIL Shock Therapy Suspension Fluid #5W Light - STLQT

The AMSOIL Shock Therapy #5 Light Suspension Fluid (STLQT) is a race-grade synthetic fluid designed for high-performance suspension systems. It is engineered to provide fast rebound and consistent damping in lighter-duty applications or colder environments.

Key Performance Benefits

• Fade-Free Performance: The advanced synthetic formula resists aeration and foaming, which are the primary causes of shock fade and inconsistent suspension feel during aggressive riding.

• Reduced Friction & Stiction: Contains specialized friction modifiers that ensure smooth transitions and immediate response to small bumps, reducing the "stickiness" often felt in standard fluids.

• Extreme Temperature Stability: With a high viscosity index of 209, this fluid maintains its protective film even under high-heat conditions while remaining fluid enough for immediate performance in sub-zero temperatures.

• Seal & Component Protection: Formulated with seal conditioners to prevent drying and cracking, alongside anti-wear agents that extend the life of internal fork and shock components.

Technical Specifications

Popular Fitment & Compatibility

The Light #5 weight is the ideal choice for systems requiring a lower-viscosity fluid for quick response:

• Shocks: Recommended for high-performance units from Ohlins, FOX, WP, and Penske.

• Forks: A premium replacement for Showa, Kayaba (KYB), and Marzocchi forks requiring a light-weight oil.

• Specialty Use: Often used as a direct replacement for Harley-Davidson Type "E" fork oil when a lighter, more responsive front-end feel is desired.
