1.244 Single Valve Springs w/Damper (16)

The PAC RACING SPRINGS 1.244 Single Valve Springs w/Damper (16) are engineered specifically for the demanding environment of circle track racing where reliability is paramount. These springs provide the necessary valve train control required for high-performance engines operating under sustained high-RPM conditions throughout a race. By ensuring consistent seat pressure and preventing catastrophic valve float, this set of sixteen springs allows racers to push their engines to the limit without sacrificing mechanical integrity. They are an essential upgrade for any competitor seeking to maintain a competitive edge on the track while ensuring their engine survives the rigors of competition.

These components from the renowned 1200 Series feature a robust single spring design integrated with an internal damper to effectively control harmonic vibrations during high-speed operation. With a stout 450 lb/in spring rate and a 1.244-inch outer diameter, they provide the tension required to manage aggressive camshaft profiles and heavy valves. The 1.100-inch coil bind height is precision-calculated to offer sufficient travel for performance lifts while preventing the spring from bottoming out under load. This technical balance ensures that the valve train remains stable and responsive even during the most grueling laps, protecting your investment from premature wear.

Designed primarily for circle track applications, the PAC RACING SPRINGS 1.244 Single Valve Springs w/Damper (16) are a critical component for engine builders looking to optimize efficiency and longevity. This complete set of sixteen ensures uniform performance across all cylinders, which is vital for maintaining balanced power delivery and preventing harmonic imbalances. Whether you are conducting a full top-end overhaul or a targeted performance upgrade, these springs offer the professional-grade durability needed for serious racing. Users should verify their retainer and valve seal compatibility to ensure a seamless installation process and optimal clearance for their specific engine configuration.
