Fade Free Formula. Maxima's Racing Shock Fluid is a blend of the finest petroleum base stocks available. With extremely high viscosity indexes over 350+, low pour points and reduced friction capability, these high performance fluids show a considerably reduced rate of viscosity change when subjected to elevated temperatures. Racing Shock Fluid will work equally well in either steel or aluminum-bodied suspension components. Racing Shock Fluid 7WT can be used when more damping is required. Extremely high viscosity indexes over 300+, low pour points and reduced friction capability. Will work equally well in either steel or aluminum-bodied suspension components. Caution: Protect from contamination and excessive heat. Technical Data: SAE viscosity: 3WT. Color D 1500: Red. Gravity: 30.5° A.P.I. Viscosity SUS @ 100°F: 75.8.
