Superior Stability for Dual Spring Setups

The PAC Racing 1.475 Titanium Valve Spring Retainers are the gold standard for dual spring valvetrain management. Built to handle the intense pressures of high-performance engines, these 500 Series titanium retainers offer an exceptional balance of weight reduction and durability. Designed for use with 10-degree locks, they ensure that your valve springs remain perfectly aligned and securely seated throughout the entire RPM range.

Technical Benefits

  • Material: High-strength Titanium construction.
  • Compatibility: Engineered for dual spring configurations.
  • Precision: 1.165 in / 0.840 in OD steps for exact fitment.
