If you are looking for the ultimate in high performance valve springs for high boost/high rev DOHC applications, then look no further than our Race Series Ovate wire springs. Designed for extreme high performance street and all-out race applications, Atomic springs are made from triple heat treated Ovate wire and provide high seat and nose pressures whilst providing extreme durability.
Ovate wire is the latest technology in spring steel wire profile and is used extensively in the USA in NASCAR, Winston Cup and Drag race applications. Ovate wire is not circular in cross section, but is elliptical (across the horizontal plane) to provide high spring pressures whilst allowing clearance for high lift camshafts. Special triple heat treatment is required to ensure consistent tempering across the entire spring section and, combined with specialised tooling required to produce the wire form, Ovate springs are quite a bit more expensive than conventionally formed wire springs. They are however, the only choice when used in short installed height, high lift, high boost, highly stressed street/race applications.
