Our proprietary furnace technology and highly specific manufacturing processes guarantee consistency from spring to spring. This allows us to offer unparalleled metallurgical integrity and the most value for your investment.
All of our hot wound springs endure in-process inspection at each step of manufacturing to ensure product conformance, and we have computerized load-testing equipment capable of testing loads from 50 pounds (23 kilograms) to 150,000 pounds (68,000 kilograms).

We begin with the highest quality raw materials to create cold wound springs from .250’’ (7mm) to .750 (18.75mm), offering high tensile chrome silicon for maximum travel.
