PAC 1300 Series Drag Race Valve Springs PAC-1331

PAC racing springs have brought the latest technology to the drag racing market. Traditional springs were made with higher load rates without concern for spring mass and frequency. PAC racing springs have taken years of research and coupled that with exotic new heat treatment methods to produce the next generation drag race springs.

These springs feature a 15-30% reduction in physical mass! This coupled with a natural frequency increase of 20% means that your engine will rev higher, faster, and last longer with more aggressive valve motion.
