Double Pigtail Spring 14x7

The Double Pigtail Spring 14x7 is a high-performance conventional coil spring engineered by Hyperco for demanding rear suspension applications. Designed with technical precision, this steel spring provides the consistent rate control necessary for maintaining vehicle balance and predictable handling under load. Whether you are looking to buy a replacement or upgrading for specific track requirements, this component meets the rigorous standards of professional racing environments.

Featuring a 175 lb/in spring rate, this specific model is optimized for setups requiring a moderate level of resistance. The 14-inch length and 7-inch outer diameter ensure compatibility with standard conventional spring perches, while the double pigtail design allows for secure seating on both the upper and lower mounts. This specialized end configuration is essential for chassis that utilize pigtail-style spring seats, preventing shifting or noise during suspension travel.

Durability is a core feature of the Hyperco engineering process, and these specifications highlight a spring built to withstand repeated compression cycles without significant rate loss or "set." The steel construction is finished with a protective black paint, providing resistance against environmental factors and corrosion. Understanding these technical specifications is vital for tuners who require exact mechanical data to calculate roll centers and weight transfer.

Reviewing the performance data of the Double Pigtail Spring 14x7 reveals its utility in various automotive disciplines where rear suspension geometry demands a 7-inch outer diameter spring. As a critical link in the suspension system, the accuracy of the 175-pound rate ensures that spring frequency remains within the desired range for the vehicle's total weight. This component is sold individually to allow for precise corner-weighting and custom tuning of the rear axle.
