Hyperco's Hypercoil Quarter Midget Springs were developed to meet the specific requirements of modern Quarter Midget racing. Hyperco’s springs were designed with input from the top Quarter Midget chassis builders and the race teams. Their OBD Hypercoils feature a unique design concept where 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 by adjusting the spring's body diameter.
Hyperco’s Quarter Midget Springs are available in spring rate increments without tolerance overlap. This ensures predictable suspension tuning for a wide range of track conditions.
Springs measure 4.25" long. Please select spring rate from the menu above.
