1.300 Dual Valve Springs (16)

The PAC Racing Springs 1.300 Dual Valve Springs are designed specifically for high-performance drag racing engines, where extreme valve control and reliability are crucial. This set includes 16 dual valve springs, catering to the needs of racers and engine builders who require precision components capable of withstanding the intense acceleration cycles and sustained RPM loads typical in competitive motorsports.

These dual spring designs enhance valve seating control and prevent float at peak power, making them essential for engines that exceed stock performance limits. The springs are manufactured using high-quality spring steel alloys and proprietary heat-treating processes, which improve fatigue resistance and longevity under extreme conditions that would typically compromise conventional street springs.

Racers building naturally aspirated small-block or big-block engines for competition will find this valve spring set particularly beneficial, especially those utilizing aggressive solid-roller cam profiles or high-lift designs that require exceptional spring pressure stability. Installation of these springs is recommended to be performed by professionals to ensure optimal performance.
