1.681 Triple Valve Springs (16)

The PAC Racing Springs 1.681 Triple Valve Springs are designed for high-performance engines that require precise valve control and consistent lift at extreme RPMs. This set of 16 springs is ideal for serious engine builders and race mechanics who need to maintain valve seating integrity while accommodating aggressive camshaft profiles.

Manufactured using precision wire and advanced coiling techniques, these 1.681-inch diameter triple valve springs ensure consistent spring rate and load characteristics across all units. The triple-spring design provides the necessary load capacity for reliable operation in high boost or nitrous applications, effectively preventing valve float during peak engine speeds.

These springs are particularly beneficial for builders working with small-block and big-block engine platforms that utilize competition-level camshafts. Each spring is individually quality-tested to meet PAC's rigorous standards, ensuring batch consistency that is critical for balanced engine performance.
