Quick Turn Springs 1-3/8in .425 10pk

The ALLSTAR PERFORMANCE Quick Turn Springs 1-3/8in .425 10-pack is designed for serious engine builders and racing enthusiasts who require precision valve train control. These compact coil springs are essential components specifically for high-performance engine valve train applications, ensuring rapid valve actuation and consistent spring pressure.

Constructed to ALLSTAR PERFORMANCE specifications, these springs feature a 1-3/8 inch outer diameter and a .425 wire diameter, engineered for optimal load characteristics and fatigue resistance. The precise dimensions and spring rate guarantee consistent valve seating and lift across the entire RPM band, which is critical for maintaining proper valve overlap and preventing float in high-lift camshaft applications.

Engine builders and mechanics rely on these Quick Turn Springs for small-block and mid-displacement engine packages, where space constraints demand compact solutions without sacrificing performance. The 10-pack quantity is ideal for complete valve train setups, ensuring uniform preload and deflection rates for enhanced engine reliability.
