    PAC 1300 Series Dual Drag Race Valve Springs are designed to have a higher rate than traditional triple springs due to heat treating and alloy advancements for a reduction in physical mass with higher frequencies. These dual drag race valve springs are coiled with a process that enhances durability by engineering the outer spring precision to interface with the inner spring. A smaller, lighter designed retainer and specially formulated spring steel ensures consistency and performance that substantially increases the longevity in extreme conditions, such as professional drag racing. Advantages of 1300 series dual valve springs includes lighter mass, higher frequency, higher rate, extreme engine RPM capability, and increased horsepower.
