Light Weight Suspension Fluid: Similar to what many manufacturers call a "5W" or 5-weight. This fluid is often used by CORR and SCORE off road teams in their long-travel shocks due to its ability to hold viscosity under extreme conditions. Tuners use our LightWeight Suspension Fluid as a direct replacement in the rear shock on modern motocross bikes (ExtraLight 2.5 in the front forks). NHRA's Top Fuel and Funny Car teams also use this fluid as a substitute for the "water soluble" fluid used in their clutch management systems due to its ability to produce extremely consistent operation under both hot and cold racing conditions.
