Description
High-rpm stability and consistent valve control are critical when pushing your engine to the limit, and undersized or worn valve springs compromise both. The Isky 1.560 Valve Springs deliver the spring rate and damping characteristics needed for aggressive cam profiles and elevated RPM applications, ensuring your valvetrain stays synchronized under extreme load.
