Hyperco Spring, Coilover, 4.250" Length, 1.680" Diameter, 80 Rate, Blue (Quarter Midget)

Quarter (1/4) Midget Springs were developed to meet the specific requirements of modern ¼ midget racing. Hyperco’s springs were designed with input from the top ¼ midget chassis builders and the race teams. Their OBD Hypercoils feature a unique design concept. They adjust the body diameter of the spring relative to the end coils. The OBD design technique enables Hyperco to take full advantage of its extensive range of ultra-high tensile material by optimizing the applied stress through adjusting the springs body diameter.
