Hypercoils 12" UHT Barrel 2-1/2" I.D. Coil-Over Spring - 150 lb. Helmet Bill Strips Viscosity typical of 75W-110Optimum Body Diameter (OBD) Hypercoils feature a unique design concept that adjusts the body diameter of the spring relative to the end coils. The OBD design enables Hyperco to take full advantage of its ultra high tensile material by optimizing the applied stress through adjusting the spring's body diameter. The results are in and they are simply incredible: More Deflection Less Weight Increased Rate Linearity More Resistance to Bowing Fits All
