Optimum 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:
Increased Rate Linearity
More Resistance to Bowing
Fits All Standard Hardware
Maintains Free Length
