PAC 1500 Series Circle Track Springs

The PAC 1500 Series Springs were designed from PAC's historical use in Circle Track applications. These Springs go through an industry leading Nitriding Process that allows the springs to withstand the abusive wear and fatigue of the typical endurance engine environment. In addition to the Nitriding Process, these springs are prepared with ID and OD Chamfering, Nano-Peening and Load Sorting to bring you the finest endurance valve springs available. We also recommend these springs for Solid Roller Street / Strip applications with aggressive camshafts. Since the endurance springs are designed to last a very long time, they do not have as high of a spring rate as the Drag Race series springs. This makes these a great option for street driven applications because the lower spring rate will help the rest of the valve train parts last a very long time.
