The COMP Cams dual valve spring set is manufactured from Super Clean wire and built under extensive quality control to provide strength, durability and valve-train stability. Dual-spring construction better resists coil surge and manages increased lift found in extreme-stress applications. Outer/inner dimensions are 1.384" OD and .804" ID, giving a compact two-spring assembly suited to demanding builds.
